+description: Implement tasks from an OpenSpec change (Experimental)
+---
+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - Context file paths (varies by schema)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read the files listed in `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! You can archive this change with `/opsx:archive`.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+description: Archive a completed change in the experimental workflow
+---
+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, execute `/opsx:sync` logic. Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Spec sync status (synced / sync skipped / no delta specs)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success (No Delta Specs)**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** No delta specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success With Warnings**
+
+```
+## Archive Complete (with warnings)
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** Sync skipped (user chose to skip)
+
+**Warnings:**
+- Archived with 2 incomplete artifacts
+- Archived with 3 incomplete tasks
+- Delta spec sync was skipped (user chose to skip)
+
+Review the archive if this was not intentional.
+```
+
+**Output On Error (Archive Exists)**
+
+```
+## Archive Failed
+
+**Change:** <change-name>
+**Target:** openspec/changes/archive/YYYY-MM-DD-<name>/
+
+Target archive directory already exists.
+
+**Options:**
+1. Rename the existing archive
+2. Delete the existing archive if it's a duplicate
+3. Wait until a different date to archive
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use /opsx:sync approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: Archive multiple completed changes at once
+---
+
+Archive multiple completed changes in a single operation.
+
+This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.
+
+**Input**: None required (prompts for selection)
+
+**Steps**
+
+1. **Get active changes**
+
+   Run `openspec list --json` to get all active changes.
+
+   If no active changes exist, inform user and stop.
+
+2. **Prompt for change selection**
+
+   Use **AskUserQuestion tool** with multi-select to let user choose changes:
+   - Show each change with its schema
+   - Include an option for "All changes"
+   - Allow any number of selections (1+ works, 2+ is the typical use case)
+
+   **IMPORTANT**: Do NOT auto-select. Always let the user choose.
+
+3. **Batch validation - gather status for all selected changes**
+
+   For each selected change, collect:
+
+   a. **Artifact status** - Run `openspec status --change "<name>" --json`
+      - Parse `schemaName` and `artifacts` list
+      - Note which artifacts are `done` vs other states
+
+   b. **Task completion** - Read `openspec/changes/<name>/tasks.md`
+      - Count `- [ ]` (incomplete) vs `- [x]` (complete)
+      - If no tasks file exists, note as "No tasks"
+
+   c. **Delta specs** - Check `openspec/changes/<name>/specs/` directory
+      - List which capability specs exist
+      - For each, extract requirement names (lines matching `### Requirement: <name>`)
+
+4. **Detect spec conflicts**
+
+   Build a map of `capability -> [changes that touch it]`:
+
+   ```
+   auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
+   api  -> [change-c]            <- OK (only 1 change)
+   ```
+
+   A conflict exists when 2+ selected changes have delta specs for the same capability.
+
+5. **Resolve conflicts agentically**
+
+   **For each conflict**, investigate the codebase:
+
+   a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
+
+   b. **Search the codebase** for implementation evidence:
+      - Look for code implementing requirements from each delta spec
+      - Check for related files, functions, or tests
+
+   c. **Determine resolution**:
+      - If only one change is actually implemented -> sync that one's specs
+      - If both implemented -> apply in chronological order (older first, newer overwrites)
+      - If neither implemented -> skip spec sync, warn user
+
+   d. **Record resolution** for each conflict:
+      - Which change's specs to apply
+      - In what order (if both)
+      - Rationale (what was found in codebase)
+
+6. **Show consolidated status table**
+
+   Display a table summarizing all changes:
+
+   ```
+   | Change               | Artifacts | Tasks | Specs   | Conflicts | Status |
+   |---------------------|-----------|-------|---------|-----------|--------|
+   | schema-management   | Done      | 5/5   | 2 delta | None      | Ready  |
+   | project-config      | Done      | 3/3   | 1 delta | None      | Ready  |
+   | add-oauth           | Done      | 4/4   | 1 delta | auth (!)  | Ready* |
+   | add-verify-skill    | 1 left    | 2/5   | None    | None      | Warn   |
+   ```
+
+   For conflicts, show the resolution:
+   ```
+   * Conflict resolution:
+     - auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
+   ```
+
+   For incomplete changes, show warnings:
+   ```
+   Warnings:
+   - add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
+   ```
+
+7. **Confirm batch operation**
+
+   Use **AskUserQuestion tool** with a single confirmation:
+
+   - "Archive N changes?" with options based on status
+   - Options might include:
+     - "Archive all N changes"
+     - "Archive only N ready changes (skip incomplete)"
+     - "Cancel"
+
+   If there are incomplete changes, make clear they'll be archived with warnings.
+
+8. **Execute archive for each confirmed change**
+
+   Process changes in the determined order (respecting conflict resolution):
+
+   a. **Sync specs** if delta specs exist:
+      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
+      - For conflicts, apply in resolved order
+      - Track if sync was done
+
+   b. **Perform the archive**:
+      ```bash
+      mkdir -p openspec/changes/archive
+      mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+      ```
+
+   c. **Track outcome** for each change:
+      - Success: archived successfully
+      - Failed: error during archive (record error)
+      - Skipped: user chose not to archive (if applicable)
+
+9. **Display summary**
+
+   Show final results:
+
+   ```
+   ## Bulk Archive Complete
+
+   Archived 3 changes:
+   - schema-management-cli -> archive/2026-01-19-schema-management-cli/

+   - add-verify-skill (user chose not to archive incomplete)
+
+   Spec sync summary:
+   - 4 delta specs synced to main specs
+   - 1 conflict resolved (auth: applied both in chronological order)
+   ```
+
+   If any failures:
+   ```
+   Failed 1 change:
+   - some-change: Archive directory already exists
+   ```
+
+**Conflict Resolution Examples**
+
+Example 1: Only one implemented
+```
+Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
+
+Checking add-oauth:
+- Delta adds "OAuth Provider Integration" requirement
+- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
+
+Checking add-jwt:
+- Delta adds "JWT Token Handling" requirement
+- Searching codebase... no JWT implementation found
+
+Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
+```
+
+Example 2: Both implemented
+```
+Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
+
+Checking add-rest-api (created 2026-01-10):
+- Delta adds "REST Endpoints" requirement
+- Searching codebase... found src/api/rest.ts
+
+Checking add-graphql (created 2026-01-15):
+- Delta adds "GraphQL Schema" requirement
+- Searching codebase... found src/api/graphql.ts
+
+Resolution: Both implemented. Will apply add-rest-api specs first,
+then add-graphql specs (chronological order, newer takes precedence).
+```
+
+**Output On Success**
+
+```
+## Bulk Archive Complete
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+- <change-2> -> archive/YYYY-MM-DD-<change-2>/
+
+Spec sync summary:
+- N delta specs synced to main specs
+- No conflicts (or: M conflicts resolved)
+```
+
+**Output On Partial Success**
+
+```
+## Bulk Archive Complete (partial)
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+
+Skipped M changes:
+- <change-2> (user chose not to archive incomplete)
+
+Failed K changes:
+- <change-3>: Archive directory already exists
+```
+
+**Output When No Changes**
+
+```
+## No Changes to Archive
+
+No active changes found. Use `/opsx:new` to create a new change.
+```
+
+**Guardrails**
+- Allow any number of changes (1+ is fine, 2+ is the typical use case)
+- Always prompt for selection, never auto-select
+- Detect spec conflicts early and resolve by checking codebase
+- When both changes are implemented, apply specs in chronological order
+- Skip spec sync only when implementation is missing (warn user)
+- Show clear per-change status before confirming
+- Use single confirmation for entire batch
+- Track and report all outcomes (success/skip/fail)
+- Preserve .openspec.yaml when moving to archive
+- Archive directory target uses current date: YYYY-MM-DD-<name>
+- If archive target exists, fail that change but continue with others

+description: Continue working on a change - create the next artifact (Experimental)
+---
+
+Continue working on a change by creating the next artifact.
+
+**Input**: Optionally specify a change name after `/opsx:continue` (e.g., `/opsx:continue add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes sorted by most recently modified. Then use the **AskUserQuestion tool** to let the user select which change to work on.
+
+   Present the top 3-4 most recently modified changes as options, showing:
+   - Change name
+   - Schema (from `schema` field if present, otherwise "spec-driven")
+   - Status (e.g., "0/5 tasks", "complete", "no tasks")
+   - How recently it was modified (from `lastModified` field)
+
+   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check current status**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand current state. The response includes:
+   - `schemaName`: The workflow schema being used (e.g., "spec-driven")
+   - `artifacts`: Array of artifacts with their status ("done", "ready", "blocked")
+   - `isComplete`: Boolean indicating if all artifacts are complete
+
+3. **Act based on status**:
+
+   ---
+
+   **If all artifacts are complete (`isComplete: true`)**:
+   - Congratulate the user
+   - Show final status including the schema used
+   - Suggest: "All artifacts created! You can now implement this change with `/opsx:apply` or archive it with `/opsx:archive`."
+   - STOP
+
+   ---
+
+   **If artifacts are ready to create** (status shows artifacts with `status: "ready"`):
+   - Pick the FIRST artifact with `status: "ready"` from the status output
+   - Get its instructions:
+     ```bash
+     openspec instructions <artifact-id> --change "<name>" --json
+     ```
+   - Parse the JSON. The key fields are:
+     - `context`: Project background (constraints for you - do NOT include in output)
+     - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+     - `template`: The structure to use for your output file
+     - `instruction`: Schema-specific guidance
+     - `outputPath`: Where to write the artifact
+     - `dependencies`: Completed artifacts to read for context
+   - **Create the artifact file**:
+     - Read any completed dependency files for context
+     - Use `template` as the structure - fill in its sections
+     - Apply `context` and `rules` as constraints when writing - but do NOT copy them into the file
+     - Write to the output path specified in instructions
+   - Show what was created and what's now unlocked
+   - STOP after creating ONE artifact
+
+   ---
+
+   **If no artifacts are ready (all blocked)**:
+   - This shouldn't happen with a valid schema
+   - Show status and suggest checking for issues
+
+4. **After creating an artifact, show progress**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After each invocation, show:
+- Which artifact was created
+- Schema workflow being used
+- Current progress (N/M complete)
+- What artifacts are now unlocked
+- Prompt: "Run `/opsx:continue` to create the next artifact"
+
+**Artifact Creation Guidelines**
+
+The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
+
+Common artifact patterns:
+
+**spec-driven schema** (proposal → specs → design → tasks):
+- **proposal.md**: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
+  - The Capabilities section is critical - each capability listed will need a spec file.
+- **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
+- **design.md**: Document technical decisions, architecture, and implementation approach.
+- **tasks.md**: Break down implementation into checkboxed tasks.
+
+For other schemas, follow the `instruction` field from the CLI output.
+
+**Guardrails**
+- Create ONE artifact per invocation
+- Always read dependency artifacts before creating a new one
+- Never skip artifacts or create out of order
+- If context is unclear, ask the user before creating
+- Verify the artifact file exists after writing before marking progress
+- Use the schema's artifact sequence, don't assume specific artifact names
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output

+description: Enter explore mode - think through ideas, investigate problems, clarify requirements
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first (e.g., start a change with `/opsx:new` or `/opsx:ff`). You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
+- A vague idea: "real-time collaboration"
+- A specific problem: "the auth system is getting unwieldy"
+- A change name: "add-dark-mode" (to explore in context of that change)
+- A comparison: "postgres vs sqlite for this"
+- Nothing (just enter explore mode)
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+---
+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+If the user mentioned a specific change name, read its artifacts for context.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create one?"
+  → Can transition to `/opsx:new` or `/opsx:ff`
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   | Insight Type | Where to Capture |
+   |--------------|------------------|
+   | New requirement discovered | `specs/<capability>/spec.md` |
+   | Requirement changed | `specs/<capability>/spec.md` |
+   | Design decision made | `design.md` |
+   | Scope changed | `proposal.md` |
+   | New work identified | `tasks.md` |
+   | Assumption invalidated | Relevant artifact |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into action**: "Ready to start? `/opsx:new` or `/opsx:ff`"
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+description: Create a change and generate all artifacts needed for implementation in one go
+---
+
+Fast-forward through artifact creation - generate everything needed to start implementation.
+
+**Input**: The argument after `/opsx:ff` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "✓ Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use the `template` as a starting point, filling in based on context
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+description: Start a new change using the experimental artifact workflow (OPSX)
+---
+
+Start a new change using the experimental artifact-driven approach.
+
+**Input**: The argument after `/opsx:new` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Determine the workflow schema**
+
+   Use the default schema (omit `--schema`) unless the user explicitly requests a different workflow.
+
+   **Use a different schema only if the user mentions:**
+   - A specific schema name → use `--schema <name>`
+   - "show workflows" or "what workflows" → run `openspec schemas --json` and let them choose
+
+   **Otherwise**: Omit `--schema` to use the default.
+
+3. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   Add `--schema <name>` only if the user requested a specific workflow.
+   This creates a scaffolded change at `openspec/changes/<name>/` with the selected schema.
+
+4. **Show the artifact status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+   This shows which artifacts need to be created and which are ready (dependencies satisfied).
+
+5. **Get instructions for the first artifact**
+   The first artifact depends on the schema. Check the status output to find the first artifact with status "ready".
+   ```bash
+   openspec instructions <first-artifact-id> --change "<name>"
+   ```
+   This outputs the template and context for creating the first artifact.
+
+6. **STOP and wait for user direction**
+
+**Output**
+
+After completing the steps, summarize:
+- Change name and location
+- Schema/workflow being used and its artifact sequence
+- Current status (0/N artifacts complete)
+- The template for the first artifact
+- Prompt: "Ready to create the first artifact? Run `/opsx:continue` or just describe what this change is about and I'll draft it."
+
+**Guardrails**
+- Do NOT create any artifacts yet - just show the instructions
+- Do NOT advance beyond showing the first artifact template
+- If the name is invalid (not kebab-case), ask for a valid name
+- If a change with that name already exists, suggest using `/opsx:continue` instead
+- Pass --schema if using a non-default workflow

+description: Guided onboarding - walk through a complete OpenSpec workflow cycle with narration
+---
+
+Guide the user through their first complete OpenSpec workflow cycle. This is a teaching experience—you'll do real work in their codebase while explaining each step.
+
+---
+
+## Preflight
+
+Before starting, check if OpenSpec is initialized:
+
+```bash
+openspec status --json 2>&1 || echo "NOT_INITIALIZED"
+```
+
+**If not initialized:**
+> OpenSpec isn't set up in this project yet. Run `openspec init` first, then come back to `/opsx:onboard`.
+
+Stop here if not initialized.
+
+---
+
+## Phase 1: Welcome
+
+Display:
+
+```
+## Welcome to OpenSpec!
+
+I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
+
+**What we'll do:**
+1. Pick a small, real task in your codebase
+2. Explore the problem briefly
+3. Create a change (the container for our work)
+4. Build the artifacts: proposal → specs → design → tasks
+5. Implement the tasks
+6. Archive the completed change
+
+**Time:** ~15-20 minutes
+
+Let's start by finding something to work on.
+```
+
+---
+
+## Phase 2: Task Selection
+
+### Codebase Analysis
+
+Scan the codebase for small improvement opportunities. Look for:
+
+1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
+2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
+3. **Functions without tests** - Cross-reference `src/` with test directories
+4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
+5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
+6. **Missing validation** - User input handlers without validation
+
+Also check recent git activity:
+```bash
+git log --oneline -10 2>/dev/null || echo "No git history"
+```
+
+### Present Suggestions
+
+From your analysis, present 3-4 specific suggestions:
+
+```
+## Task Suggestions
+
+Based on scanning your codebase, here are some good starter tasks:
+
+**1. [Most promising task]**
+   Location: `src/path/to/file.ts:42`
+   Scope: ~1-2 files, ~20-30 lines
+   Why it's good: [brief reason]
+
+**2. [Second task]**
+   Location: `src/another/file.ts`
+   Scope: ~1 file, ~15 lines
+   Why it's good: [brief reason]
+
+**3. [Third task]**
+   Location: [location]
+   Scope: [estimate]
+   Why it's good: [brief reason]
+
+**4. Something else?**
+   Tell me what you'd like to work on.
+
+Which task interests you? (Pick a number or describe your own)
+```
+
+**If nothing found:** Fall back to asking what the user wants to build:
+> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
+
+### Scope Guardrail
+
+If the user picks or describes something too large (major feature, multi-day work):
+
+```
+That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
+
+For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
+
+**Options:**
+1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
+2. **Pick something else** - One of the other suggestions, or a different small task?
+3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
+
+What would you prefer?
+```
+
+Let the user override if they insist—this is a soft guardrail.
+
+---
+
+## Phase 3: Explore Demo
+
+Once a task is selected, briefly demonstrate explore mode:
+
+```
+Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
+```
+
+Spend 1-2 minutes investigating the relevant code:
+- Read the file(s) involved
+- Draw a quick ASCII diagram if it helps
+- Note any considerations
+
+```
+## Quick Exploration
+
+[Your brief analysis—what you found, any considerations]
+
+┌─────────────────────────────────────────┐
+│   [Optional: ASCII diagram if helpful]  │
+└─────────────────────────────────────────┘
+
+Explore mode (`/opsx:explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
+
+Now let's create a change to hold our work.
+```
+
+**PAUSE** - Wait for user acknowledgment before proceeding.
+
+---
+
+## Phase 4: Create the Change
+
+**EXPLAIN:**
+```
+## Creating a Change
+
+A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives in `openspec/changes/<name>/` and holds your artifacts—proposal, specs, design, tasks.
+
+Let me create one for our task.
+```
+
+**DO:** Create the change with a derived kebab-case name:
+```bash
+openspec new change "<derived-name>"
+```
+
+**SHOW:**
+```
+Created: `openspec/changes/<name>/`
+
+The folder structure:
+```
+openspec/changes/<name>/
+├── proposal.md    ← Why we're doing this (empty, we'll fill it)
+├── design.md      ← How we'll build it (empty)
+├── specs/         ← Detailed requirements (empty)
+└── tasks.md       ← Implementation checklist (empty)
+```
+
+Now let's fill in the first artifact—the proposal.
+```
+
+---
+
+## Phase 5: Proposal
+
+**EXPLAIN:**
+```
+## The Proposal
+
+The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
+
+I'll draft one based on our task.
+```
+
+**DO:** Draft the proposal content (don't save yet):
+
+```
+Here's a draft proposal:
+
+---
+
+## Why
+
+[1-2 sentences explaining the problem/opportunity]
+
+## What Changes
+
+[Bullet points of what will be different]
+
+## Capabilities
+
+### New Capabilities
+- `<capability-name>`: [brief description]
+
+### Modified Capabilities
+<!-- If modifying existing behavior -->
+
+## Impact
+
+- `src/path/to/file.ts`: [what changes]
+- [other files if applicable]
+
+---
+
+Does this capture the intent? I can adjust before we save it.
+```
+
+**PAUSE** - Wait for user approval/feedback.
+
+After approval, save the proposal:
+```bash
+openspec instructions proposal --change "<name>" --json
+```
+Then write the content to `openspec/changes/<name>/proposal.md`.
+
+```
+Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
+
+Next up: specs.
+```
+
+---
+
+## Phase 6: Specs
+
+**EXPLAIN:**
+```
+## Specs
+
+Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
+
+For a small task like this, we might only need one spec file.
+```
+
+**DO:** Create the spec file:
+```bash
+mkdir -p openspec/changes/<name>/specs/<capability-name>
+```
+
+Draft the spec content:
+
+```
+Here's the spec:
+
+---
+
+## ADDED Requirements
+
+### Requirement: <Name>
+
+<Description of what the system should do>
+
+#### Scenario: <Scenario name>
+
+- **WHEN** <trigger condition>
+- **THEN** <expected outcome>
+- **AND** <additional outcome if needed>
+
+---
+
+This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
+```
+
+Save to `openspec/changes/<name>/specs/<capability>/spec.md`.
+
+---
+
+## Phase 7: Design
+
+**EXPLAIN:**
+```
+## Design
+
+The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
+
+For small changes, this might be brief. That's fine—not every change needs deep design discussion.
+```
+
+**DO:** Draft design.md:
+
+```
+Here's the design:
+
+---
+
+## Context
+
+[Brief context about the current state]
+
+## Goals / Non-Goals
+
+**Goals:**
+- [What we're trying to achieve]
+
+**Non-Goals:**
+- [What's explicitly out of scope]
+
+## Decisions
+
+### Decision 1: [Key decision]
+
+[Explanation of approach and rationale]
+
+---
+
+For a small task, this captures the key decisions without over-engineering.
+```
+
+Save to `openspec/changes/<name>/design.md`.
+
+---
+
+## Phase 8: Tasks
+
+**EXPLAIN:**
+```
+## Tasks
+
+Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
+
+These should be small, clear, and in logical order.
+```
+
+**DO:** Generate tasks based on specs and design:
+
+```
+Here are the implementation tasks:
+
+---
+
+## 1. [Category or file]
+
+- [ ] 1.1 [Specific task]
+- [ ] 1.2 [Specific task]
+
+## 2. Verify
+
+- [ ] 2.1 [Verification step]
+
+---
+
+Each checkbox becomes a unit of work in the apply phase. Ready to implement?
+```
+
+**PAUSE** - Wait for user to confirm they're ready to implement.
+
+Save to `openspec/changes/<name>/tasks.md`.
+
+---
+
+## Phase 9: Apply (Implementation)
+
+**EXPLAIN:**
+```
+## Implementation
+
+Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
+```
+
+**DO:** For each task:
+
+1. Announce: "Working on task N: [description]"
+2. Implement the change in the codebase
+3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
+4. Mark complete in tasks.md: `- [ ]` → `- [x]`
+5. Brief status: "✓ Task N complete"
+
+Keep narration light—don't over-explain every line of code.
+
+After all tasks:
+
+```
+## Implementation Complete
+
+All tasks done:
+- [x] Task 1
+- [x] Task 2
+- [x] ...
+
+The change is implemented! One more step—let's archive it.
+```
+
+---
+
+## Phase 10: Archive
+
+**EXPLAIN:**
+```
+## Archiving
+
+When a change is complete, we archive it. This moves it from `openspec/changes/` to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
+
+Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
+```
+
+**DO:**
+```bash
+openspec archive "<name>"
+```
+
+**SHOW:**
+```
+Archived to: `openspec/changes/archive/YYYY-MM-DD-<name>/`
+
+The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
+```
+
+---
+
+## Phase 11: Recap & Next Steps
+
+```
+## Congratulations!
+
+You just completed a full OpenSpec cycle:
+
+1. **Explore** - Thought through the problem
+2. **New** - Created a change container
+3. **Proposal** - Captured WHY
+4. **Specs** - Defined WHAT in detail
+5. **Design** - Decided HOW
+6. **Tasks** - Broke it into steps
+7. **Apply** - Implemented the work
+8. **Archive** - Preserved the record
+
+This same rhythm works for any size change—a small fix or a major feature.
+

+
+## Command Reference
+
+| Command | What it does |
+|---------|--------------|
+| `/opsx:explore` | Think through problems before/during work |
+| `/opsx:new` | Start a new change, step through artifacts |
+| `/opsx:ff` | Fast-forward: create all artifacts at once |
+| `/opsx:continue` | Continue working on an existing change |
+| `/opsx:apply` | Implement tasks from a change |
+| `/opsx:verify` | Verify implementation matches artifacts |
+| `/opsx:archive` | Archive a completed change |
+
+---
+
+## What's Next?
+
+Try `/opsx:new` or `/opsx:ff` on something you actually want to build. You've got the rhythm now!
+```
+
+---
+
+## Graceful Exit Handling
+
+### User wants to stop mid-way
+
+If the user says they need to stop, want to pause, or seem disengaged:
+
+```
+No problem! Your change is saved at `openspec/changes/<name>/`.
+
+To pick up where we left off later:
+- `/opsx:continue <name>` - Resume artifact creation
+- `/opsx:apply <name>` - Jump to implementation (if tasks exist)
+
+The work won't be lost. Come back whenever you're ready.
+```
+
+Exit gracefully without pressure.
+
+### User just wants command reference
+
+If the user says they just want to see the commands or skip the tutorial:
+
+```
+## OpenSpec Quick Reference
+
+| Command | What it does |
+|---------|--------------|
+| `/opsx:explore` | Think through problems (no code changes) |
+| `/opsx:new <name>` | Start a new change, step by step |
+| `/opsx:ff <name>` | Fast-forward: all artifacts at once |
+| `/opsx:continue <name>` | Continue an existing change |
+| `/opsx:apply <name>` | Implement tasks |
+| `/opsx:verify <name>` | Verify implementation |
+| `/opsx:archive <name>` | Archive when done |
+
+Try `/opsx:new` to start your first change, or `/opsx:ff` if you want to move fast.
+```
+
+Exit gracefully.
+
+---
+
+## Guardrails
+
+- **Follow the EXPLAIN → DO → SHOW → PAUSE pattern** at key transitions (after explore, after proposal draft, after tasks, after archive)
+- **Keep narration light** during implementation—teach without lecturing
+- **Don't skip phases** even if the change is small—the goal is teaching the workflow
+- **Pause for acknowledgment** at marked points, but don't over-pause
+- **Handle exits gracefully**—never pressure the user to continue
+- **Use real codebase tasks**—don't simulate or use fake examples
+- **Adjust scope gently**—guide toward smaller tasks but respect user choice

+description: Sync delta specs from a change to main specs
+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Input**: Optionally specify a change name after `/opsx:sync` (e.g., `/opsx:sync add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Find delta specs**
+
+   Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+3. **For each delta spec, apply changes to main specs**
+
+   For each capability with a delta spec at `openspec/changes/<name>/specs/<capability>/spec.md`:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+4. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+description: Verify implementation matches change artifacts before archiving
+---
+
+Verify that an implementation matches the change artifacts (specs, tasks, design).
+
+**Input**: Optionally specify a change name after `/opsx:verify` (e.g., `/opsx:verify add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have implementation tasks (tasks artifact exists).
+   Include the schema used for each change if available.
+   Mark changes with incomplete tasks as "(In Progress)".
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifacts exist for this change
+
+3. **Get the change directory and load artifacts**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns the change directory and context files. Read all available artifacts from `contextFiles`.
+
+4. **Initialize verification report structure**
+
+   Create a report structure with three dimensions:
+   - **Completeness**: Track tasks and spec coverage
+   - **Correctness**: Track requirement implementation and scenario coverage
+   - **Coherence**: Track design adherence and pattern consistency
+
+   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
+
+5. **Verify Completeness**
+
+   **Task Completion**:
+   - If tasks.md exists in contextFiles, read it
+   - Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
+   - Count complete vs total tasks
+   - If incomplete tasks exist:
+     - Add CRITICAL issue for each incomplete task
+     - Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
+
+   **Spec Coverage**:
+   - If delta specs exist in `openspec/changes/<name>/specs/`:
+     - Extract all requirements (marked with "### Requirement:")
+     - For each requirement:
+       - Search codebase for keywords related to the requirement
+       - Assess if implementation likely exists
+     - If requirements appear unimplemented:
+       - Add CRITICAL issue: "Requirement not found: <requirement name>"
+       - Recommendation: "Implement requirement X: <description>"
+
+6. **Verify Correctness**
+
+   **Requirement Implementation Mapping**:
+   - For each requirement from delta specs:
+     - Search codebase for implementation evidence
+     - If found, note file paths and line ranges
+     - Assess if implementation matches requirement intent
+     - If divergence detected:
+       - Add WARNING: "Implementation may diverge from spec: <details>"
+       - Recommendation: "Review <file>:<lines> against requirement X"
+
+   **Scenario Coverage**:
+   - For each scenario in delta specs (marked with "#### Scenario:"):
+     - Check if conditions are handled in code
+     - Check if tests exist covering the scenario
+     - If scenario appears uncovered:
+       - Add WARNING: "Scenario not covered: <scenario name>"
+       - Recommendation: "Add test or implementation for scenario: <description>"
+
+7. **Verify Coherence**
+
+   **Design Adherence**:
+   - If design.md exists in contextFiles:
+     - Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
+     - Verify implementation follows those decisions
+     - If contradiction detected:
+       - Add WARNING: "Design decision not followed: <decision>"
+       - Recommendation: "Update implementation or revise design.md to match reality"
+   - If no design.md: Skip design adherence check, note "No design.md to verify against"
+
+   **Code Pattern Consistency**:
+   - Review new code for consistency with project patterns
+   - Check file naming, directory structure, coding style
+   - If significant deviations found:
+     - Add SUGGESTION: "Code pattern deviation: <details>"
+     - Recommendation: "Consider following project pattern: <example>"
+
+8. **Generate Verification Report**
+
+   **Summary Scorecard**:
+   ```
+   ## Verification Report: <change-name>
+
+   ### Summary
+   | Dimension    | Status           |
+   |--------------|------------------|
+   | Completeness | X/Y tasks, N reqs|
+   | Correctness  | M/N reqs covered |
+   | Coherence    | Followed/Issues  |
+   ```
+
+   **Issues by Priority**:
+
+   1. **CRITICAL** (Must fix before archive):
+      - Incomplete tasks
+      - Missing requirement implementations
+      - Each with specific, actionable recommendation
+
+   2. **WARNING** (Should fix):
+      - Spec/design divergences
+      - Missing scenario coverage
+      - Each with specific recommendation
+
+   3. **SUGGESTION** (Nice to fix):
+      - Pattern inconsistencies
+      - Minor improvements
+      - Each with specific recommendation
+
+   **Final Assessment**:
+   - If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
+   - If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
+   - If all clear: "All checks passed. Ready for archive."
+
+**Verification Heuristics**
+
+- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
+- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
+- **Coherence**: Look for glaring inconsistencies, don't nitpick style
+- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
+- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
+
+**Graceful Degradation**
+
+- If only tasks.md exists: verify task completion only, skip spec/design checks
+- If tasks + specs exist: verify completeness and correctness, skip design
+- If full artifacts: verify all three dimensions
+- Always note which checks were skipped and why
+
+**Output Format**
+
+Use clear markdown with:
+- Table for summary scorecard
+- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
+- Code references in format: `file.ts:123`
+- Specific, actionable recommendations
+- No vague suggestions like "consider reviewing"

+---
+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - Context file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read the files listed in `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**

+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, execute /opsx:sync logic (use the openspec-sync-specs skill). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use openspec-sync-specs approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+
+Archive multiple completed changes in a single operation.
+
+This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.
+
+**Input**: None required (prompts for selection)
+
+**Steps**
+
+1. **Get active changes**
+
+   Run `openspec list --json` to get all active changes.
+
+   If no active changes exist, inform user and stop.
+
+2. **Prompt for change selection**
+
+   Use **AskUserQuestion tool** with multi-select to let user choose changes:
+   - Show each change with its schema
+   - Include an option for "All changes"
+   - Allow any number of selections (1+ works, 2+ is the typical use case)
+
+   **IMPORTANT**: Do NOT auto-select. Always let the user choose.
+
+3. **Batch validation - gather status for all selected changes**
+
+   For each selected change, collect:
+
+   a. **Artifact status** - Run `openspec status --change "<name>" --json`
+      - Parse `schemaName` and `artifacts` list
+      - Note which artifacts are `done` vs other states
+
+   b. **Task completion** - Read `openspec/changes/<name>/tasks.md`
+      - Count `- [ ]` (incomplete) vs `- [x]` (complete)
+      - If no tasks file exists, note as "No tasks"
+
+   c. **Delta specs** - Check `openspec/changes/<name>/specs/` directory
+      - List which capability specs exist
+      - For each, extract requirement names (lines matching `### Requirement: <name>`)
+
+4. **Detect spec conflicts**
+
+   Build a map of `capability -> [changes that touch it]`:
+
+   ```
+   auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
+   api  -> [change-c]            <- OK (only 1 change)
+   ```
+
+   A conflict exists when 2+ selected changes have delta specs for the same capability.
+
+5. **Resolve conflicts agentically**
+
+   **For each conflict**, investigate the codebase:
+
+   a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
+
+   b. **Search the codebase** for implementation evidence:
+      - Look for code implementing requirements from each delta spec
+      - Check for related files, functions, or tests
+
+   c. **Determine resolution**:
+      - If only one change is actually implemented -> sync that one's specs
+      - If both implemented -> apply in chronological order (older first, newer overwrites)
+      - If neither implemented -> skip spec sync, warn user
+
+   d. **Record resolution** for each conflict:
+      - Which change's specs to apply
+      - In what order (if both)
+      - Rationale (what was found in codebase)
+
+6. **Show consolidated status table**
+
+   Display a table summarizing all changes:
+
+   ```
+   | Change               | Artifacts | Tasks | Specs   | Conflicts | Status |
+   |---------------------|-----------|-------|---------|-----------|--------|
+   | schema-management   | Done      | 5/5   | 2 delta | None      | Ready  |
+   | project-config      | Done      | 3/3   | 1 delta | None      | Ready  |
+   | add-oauth           | Done      | 4/4   | 1 delta | auth (!)  | Ready* |
+   | add-verify-skill    | 1 left    | 2/5   | None    | None      | Warn   |
+   ```
+
+   For conflicts, show the resolution:
+   ```
+   * Conflict resolution:
+     - auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
+   ```
+
+   For incomplete changes, show warnings:
+   ```
+   Warnings:
+   - add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
+   ```
+
+7. **Confirm batch operation**
+
+   Use **AskUserQuestion tool** with a single confirmation:
+
+   - "Archive N changes?" with options based on status
+   - Options might include:
+     - "Archive all N changes"
+     - "Archive only N ready changes (skip incomplete)"
+     - "Cancel"
+
+   If there are incomplete changes, make clear they'll be archived with warnings.
+
+8. **Execute archive for each confirmed change**
+
+   Process changes in the determined order (respecting conflict resolution):
+
+   a. **Sync specs** if delta specs exist:
+      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
+      - For conflicts, apply in resolved order
+      - Track if sync was done
+
+   b. **Perform the archive**:
+      ```bash
+      mkdir -p openspec/changes/archive
+      mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+      ```
+
+   c. **Track outcome** for each change:
+      - Success: archived successfully
+      - Failed: error during archive (record error)
+      - Skipped: user chose not to archive (if applicable)
+
+9. **Display summary**
+
+   Show final results:
+
+   ```
+   ## Bulk Archive Complete
+
+   Archived 3 changes:
+   - schema-management-cli -> archive/2026-01-19-schema-management-cli/
+   - project-config -> archive/2026-01-19-project-config/
+   - add-oauth -> archive/2026-01-19-add-oauth/
+
+   Skipped 1 change:
+   - add-verify-skill (user chose not to archive incomplete)
+
+   Spec sync summary:
+   - 4 delta specs synced to main specs
+   - 1 conflict resolved (auth: applied both in chronological order)
+   ```
+
+   If any failures:
+   ```
+   Failed 1 change:
+   - some-change: Archive directory already exists
+   ```
+
+**Conflict Resolution Examples**
+
+Example 1: Only one implemented
+```
+Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
+
+Checking add-oauth:
+- Delta adds "OAuth Provider Integration" requirement
+- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
+
+Checking add-jwt:
+- Delta adds "JWT Token Handling" requirement
+- Searching codebase... no JWT implementation found
+
+Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
+```
+
+Example 2: Both implemented
+```
+Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
+
+Checking add-rest-api (created 2026-01-10):
+- Delta adds "REST Endpoints" requirement
+- Searching codebase... found src/api/rest.ts
+
+Checking add-graphql (created 2026-01-15):
+- Delta adds "GraphQL Schema" requirement
+- Searching codebase... found src/api/graphql.ts
+
+Resolution: Both implemented. Will apply add-rest-api specs first,
+then add-graphql specs (chronological order, newer takes precedence).
+```
+
+**Output On Success**
+
+```
+## Bulk Archive Complete
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+- <change-2> -> archive/YYYY-MM-DD-<change-2>/
+
+Spec sync summary:
+- N delta specs synced to main specs
+- No conflicts (or: M conflicts resolved)
+```
+
+**Output On Partial Success**
+
+```
+## Bulk Archive Complete (partial)
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+
+Skipped M changes:
+- <change-2> (user chose not to archive incomplete)
+
+Failed K changes:
+- <change-3>: Archive directory already exists
+```
+
+**Output When No Changes**
+
+```
+## No Changes to Archive
+
+No active changes found. Use `/opsx:new` to create a new change.
+```
+
+**Guardrails**
+- Allow any number of changes (1+ is fine, 2+ is the typical use case)
+- Always prompt for selection, never auto-select
+- Detect spec conflicts early and resolve by checking codebase
+- When both changes are implemented, apply specs in chronological order
+- Skip spec sync only when implementation is missing (warn user)
+- Show clear per-change status before confirming
+- Use single confirmation for entire batch
+- Track and report all outcomes (success/skip/fail)
+- Preserve .openspec.yaml when moving to archive
+- Archive directory target uses current date: YYYY-MM-DD-<name>
+- If archive target exists, fail that change but continue with others

+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes sorted by most recently modified. Then use the **AskUserQuestion tool** to let the user select which change to work on.
+
+   Present the top 3-4 most recently modified changes as options, showing:
+   - Change name
+   - Schema (from `schema` field if present, otherwise "spec-driven")
+   - Status (e.g., "0/5 tasks", "complete", "no tasks")
+   - How recently it was modified (from `lastModified` field)
+
+   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check current status**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand current state. The response includes:
+   - `schemaName`: The workflow schema being used (e.g., "spec-driven")
+   - `artifacts`: Array of artifacts with their status ("done", "ready", "blocked")
+   - `isComplete`: Boolean indicating if all artifacts are complete
+
+3. **Act based on status**:
+
+   ---
+
+   **If all artifacts are complete (`isComplete: true`)**:
+   - Congratulate the user
+   - Show final status including the schema used
+   - Suggest: "All artifacts created! You can now implement this change or archive it."
+   - STOP
+
+   ---
+
+   **If artifacts are ready to create** (status shows artifacts with `status: "ready"`):
+   - Pick the FIRST artifact with `status: "ready"` from the status output
+   - Get its instructions:
+     ```bash
+     openspec instructions <artifact-id> --change "<name>" --json
+     ```
+   - Parse the JSON. The key fields are:
+     - `context`: Project background (constraints for you - do NOT include in output)
+     - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+     - `template`: The structure to use for your output file
+     - `instruction`: Schema-specific guidance
+     - `outputPath`: Where to write the artifact
+     - `dependencies`: Completed artifacts to read for context
+   - **Create the artifact file**:
+     - Read any completed dependency files for context
+     - Use `template` as the structure - fill in its sections
+     - Apply `context` and `rules` as constraints when writing - but do NOT copy them into the file
+     - Write to the output path specified in instructions
+   - Show what was created and what's now unlocked
+   - STOP after creating ONE artifact
+
+   ---
+
+   **If no artifacts are ready (all blocked)**:
+   - This shouldn't happen with a valid schema
+   - Show status and suggest checking for issues
+
+4. **After creating an artifact, show progress**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After each invocation, show:
+- Which artifact was created
+- Schema workflow being used
+- Current progress (N/M complete)
+- What artifacts are now unlocked
+- Prompt: "Want to continue? Just ask me to continue or tell me what to do next."
+
+**Artifact Creation Guidelines**
+
+The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
+
+Common artifact patterns:
+
+**spec-driven schema** (proposal → specs → design → tasks):
+- **proposal.md**: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
+  - The Capabilities section is critical - each capability listed will need a spec file.
+- **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
+- **design.md**: Document technical decisions, architecture, and implementation approach.
+- **tasks.md**: Break down implementation into checkboxed tasks.
+
+For other schemas, follow the `instruction` field from the CLI output.
+
+**Guardrails**
+- Create ONE artifact per invocation
+- Always read dependency artifacts before creating a new one
+- Never skip artifacts or create out of order
+- If context is unclear, ask the user before creating
+- Verify the artifact file exists after writing before marking progress
+- Use the schema's artifact sequence, don't assume specific artifact names
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output

+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.1.1"
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first (e.g., start a change with `/opsx:new` or `/opsx:ff`). You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**
+```

+
+---
+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create one?"
+  → Can transition to `/opsx:new` or `/opsx:ff`
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+   | Insight Type | Where to Capture |
+   |--------------|------------------|
+   | New requirement discovered | `specs/<capability>/spec.md` |
+   | Requirement changed | `specs/<capability>/spec.md` |
+   | Design decision made | `design.md` |
+   | Scope changed | `proposal.md` |
+   | New work identified | `tasks.md` |
+   | Assumption invalidated | Relevant artifact |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do

+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into action**: "Ready to start? /opsx:new or /opsx:ff"
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Create a change: /opsx:new <name>
+- Fast-forward to tasks: /opsx:ff <name>
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+
+Fast-forward through artifact creation - generate everything needed to start implementation in one go.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "✓ Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, suggest continuing that change instead
+- Verify each artifact file exists after writing before proceeding to next

+
+Start a new change using the experimental artifact-driven approach.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Determine the workflow schema**
+
+   Use the default schema (omit `--schema`) unless the user explicitly requests a different workflow.
+
+   **Use a different schema only if the user mentions:**
+   - A specific schema name → use `--schema <name>`
+   - "show workflows" or "what workflows" → run `openspec schemas --json` and let them choose
+
+   **Otherwise**: Omit `--schema` to use the default.
+
+3. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   Add `--schema <name>` only if the user requested a specific workflow.
+   This creates a scaffolded change at `openspec/changes/<name>/` with the selected schema.
+
+4. **Show the artifact status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+   This shows which artifacts need to be created and which are ready (dependencies satisfied).
+
+5. **Get instructions for the first artifact**
+   The first artifact depends on the schema (e.g., `proposal` for spec-driven).
+   Check the status output to find the first artifact with status "ready".
+   ```bash
+   openspec instructions <first-artifact-id> --change "<name>"
+   ```
+   This outputs the template and context for creating the first artifact.
+
+6. **STOP and wait for user direction**
+
+**Output**
+
+After completing the steps, summarize:
+- Change name and location
+- Schema/workflow being used and its artifact sequence
+- Current status (0/N artifacts complete)
+- The template for the first artifact
+- Prompt: "Ready to create the first artifact? Just describe what this change is about and I'll draft it, or ask me to continue."
+
+**Guardrails**
+- Do NOT create any artifacts yet - just show the instructions
+- Do NOT advance beyond showing the first artifact template
+- If the name is invalid (not kebab-case), ask for a valid name
+- If a change with that name already exists, suggest continuing that change instead
+- Pass --schema if using a non-default workflow

+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.1.1"
+---
+
+Guide the user through their first complete OpenSpec workflow cycle. This is a teaching experience—you'll do real work in their codebase while explaining each step.
+
+---
+
+## Preflight
+
+Before starting, check if OpenSpec is initialized:
+
+```bash
+openspec status --json 2>&1 || echo "NOT_INITIALIZED"
+```
+
+**If not initialized:**
+> OpenSpec isn't set up in this project yet. Run `openspec init` first, then come back to `/opsx:onboard`.
+
+Stop here if not initialized.
+
+---
+
+## Phase 1: Welcome
+
+Display:
+
+```
+## Welcome to OpenSpec!
+
+I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
+
+**What we'll do:**
+1. Pick a small, real task in your codebase
+2. Explore the problem briefly
+3. Create a change (the container for our work)
+4. Build the artifacts: proposal → specs → design → tasks
+5. Implement the tasks
+6. Archive the completed change
+
+**Time:** ~15-20 minutes
+
+Let's start by finding something to work on.
+```
+
+---
+
+## Phase 2: Task Selection
+
+### Codebase Analysis
+
+Scan the codebase for small improvement opportunities. Look for:
+
+1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
+2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
+3. **Functions without tests** - Cross-reference `src/` with test directories
+4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
+5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
+6. **Missing validation** - User input handlers without validation
+
+Also check recent git activity:
+```bash
+git log --oneline -10 2>/dev/null || echo "No git history"
+```
+
+### Present Suggestions
+
+From your analysis, present 3-4 specific suggestions:
+
+```
+## Task Suggestions
+
+Based on scanning your codebase, here are some good starter tasks:
+
+**1. [Most promising task]**
+   Location: `src/path/to/file.ts:42`
+   Scope: ~1-2 files, ~20-30 lines
+   Why it's good: [brief reason]
+
+**2. [Second task]**
+   Location: `src/another/file.ts`
+   Scope: ~1 file, ~15 lines
+   Why it's good: [brief reason]
+
+**3. [Third task]**
+   Location: [location]
+   Scope: [estimate]
+   Why it's good: [brief reason]
+
+**4. Something else?**
+   Tell me what you'd like to work on.
+
+Which task interests you? (Pick a number or describe your own)
+```
+
+**If nothing found:** Fall back to asking what the user wants to build:
+> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
+
+### Scope Guardrail
+
+If the user picks or describes something too large (major feature, multi-day work):
+
+```
+That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
+
+For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
+
+**Options:**
+1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
+2. **Pick something else** - One of the other suggestions, or a different small task?
+3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
+
+What would you prefer?
+```
+
+Let the user override if they insist—this is a soft guardrail.
+
+---
+
+## Phase 3: Explore Demo
+
+Once a task is selected, briefly demonstrate explore mode:
+
+```
+Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
+```
+
+Spend 1-2 minutes investigating the relevant code:
+- Read the file(s) involved
+- Draw a quick ASCII diagram if it helps
+- Note any considerations
+
+```
+## Quick Exploration
+
+[Your brief analysis—what you found, any considerations]
+
+┌─────────────────────────────────────────┐
+│   [Optional: ASCII diagram if helpful]  │
+└─────────────────────────────────────────┘
+
+Explore mode (`/opsx:explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
+
+Now let's create a change to hold our work.
+```
+
+**PAUSE** - Wait for user acknowledgment before proceeding.
+
+---
+
+## Phase 4: Create the Change
+
+**EXPLAIN:**
+```
+## Creating a Change
+
+A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives in `openspec/changes/<name>/` and holds your artifacts—proposal, specs, design, tasks.
+
+Let me create one for our task.
+```
+
+**DO:** Create the change with a derived kebab-case name:
+```bash
+openspec new change "<derived-name>"
+```
+
+**SHOW:**
+```
+Created: `openspec/changes/<name>/`
+
+The folder structure:
+```
+openspec/changes/<name>/
+├── proposal.md    ← Why we're doing this (empty, we'll fill it)
+├── design.md      ← How we'll build it (empty)
+├── specs/         ← Detailed requirements (empty)
+└── tasks.md       ← Implementation checklist (empty)
+```
+
+Now let's fill in the first artifact—the proposal.
+```
+
+---
+
+## Phase 5: Proposal
+
+**EXPLAIN:**
+```
+## The Proposal
+
+The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
+
+I'll draft one based on our task.
+```
+
+**DO:** Draft the proposal content (don't save yet):
+
+```
+Here's a draft proposal:
+
+---
+
+## Why
+
+[1-2 sentences explaining the problem/opportunity]
+
+## What Changes
+
+[Bullet points of what will be different]
+
+## Capabilities
+
+### New Capabilities
+- `<capability-name>`: [brief description]
+
+### Modified Capabilities
+<!-- If modifying existing behavior -->
+
+## Impact
+
+- `src/path/to/file.ts`: [what changes]
+- [other files if applicable]
+
+---
+
+Does this capture the intent? I can adjust before we save it.
+```
+
+**PAUSE** - Wait for user approval/feedback.
+
+After approval, save the proposal:
+```bash
+openspec instructions proposal --change "<name>" --json
+```
+Then write the content to `openspec/changes/<name>/proposal.md`.
+
+```
+Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
+
+Next up: specs.
+```
+
+---
+
+## Phase 6: Specs
+
+**EXPLAIN:**
+```
+## Specs
+
+Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
+
+For a small task like this, we might only need one spec file.
+```
+
+**DO:** Create the spec file:
+```bash
+mkdir -p openspec/changes/<name>/specs/<capability-name>
+```
+
+Draft the spec content:
+
+```
+Here's the spec:
+
+---
+
+## ADDED Requirements
+
+### Requirement: <Name>
+
+<Description of what the system should do>
+
+#### Scenario: <Scenario name>
+
+- **WHEN** <trigger condition>
+- **THEN** <expected outcome>
+- **AND** <additional outcome if needed>
+
+---
+
+This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
+```
+
+Save to `openspec/changes/<name>/specs/<capability>/spec.md`.
+
+---
+
+## Phase 7: Design
+
+**EXPLAIN:**
+```
+## Design
+
+The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
+
+For small changes, this might be brief. That's fine—not every change needs deep design discussion.
+```
+
+**DO:** Draft design.md:
+
+```
+Here's the design:
+
+---
+
+## Context
+
+[Brief context about the current state]
+
+## Goals / Non-Goals
+
+**Goals:**
+- [What we're trying to achieve]
+
+**Non-Goals:**
+- [What's explicitly out of scope]
+
+## Decisions
+
+### Decision 1: [Key decision]
+
+[Explanation of approach and rationale]
+
+---
+
+For a small task, this captures the key decisions without over-engineering.
+```
+
+Save to `openspec/changes/<name>/design.md`.
+
+---
+
+## Phase 8: Tasks
+
+**EXPLAIN:**
+```
+## Tasks
+
+Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
+
+These should be small, clear, and in logical order.
+```
+
+**DO:** Generate tasks based on specs and design:
+
+```
+Here are the implementation tasks:
+
+---
+
+## 1. [Category or file]
+
+- [ ] 1.1 [Specific task]
+- [ ] 1.2 [Specific task]
+
+## 2. Verify
+
+- [ ] 2.1 [Verification step]
+
+---
+
+Each checkbox becomes a unit of work in the apply phase. Ready to implement?
+```
+
+**PAUSE** - Wait for user to confirm they're ready to implement.
+
+Save to `openspec/changes/<name>/tasks.md`.
+
+---
+
+## Phase 9: Apply (Implementation)
+
+**EXPLAIN:**
+```
+## Implementation
+
+Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
+```
+
+**DO:** For each task:
+
+1. Announce: "Working on task N: [description]"
+2. Implement the change in the codebase
+3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
+4. Mark complete in tasks.md: `- [ ]` → `- [x]`
+5. Brief status: "✓ Task N complete"
+
+Keep narration light—don't over-explain every line of code.
+
+After all tasks:
+
+```
+## Implementation Complete
+
+All tasks done:
+- [x] Task 1
+- [x] Task 2
+- [x] ...
+
+The change is implemented! One more step—let's archive it.
+```
+
+---
+
+## Phase 10: Archive
+
+**EXPLAIN:**
+```
+## Archiving
+
+When a change is complete, we archive it. This moves it from `openspec/changes/` to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
+
+Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
+```
+
+**DO:**
+```bash
+openspec archive "<name>"
+```
+
+**SHOW:**
+```
+Archived to: `openspec/changes/archive/YYYY-MM-DD-<name>/`
+
+The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
+```
+
+---
+
+## Phase 11: Recap & Next Steps
+
+```
+## Congratulations!
+
+You just completed a full OpenSpec cycle:
+
+1. **Explore** - Thought through the problem
+2. **New** - Created a change container
+3. **Proposal** - Captured WHY
+4. **Specs** - Defined WHAT in detail
+5. **Design** - Decided HOW
+6. **Tasks** - Broke it into steps
+7. **Apply** - Implemented the work
+8. **Archive** - Preserved the record
+
+This same rhythm works for any size change—a small fix or a major feature.
+

+
+## Command Reference
+
+| Command | What it does |
+|---------|--------------|
+| `/opsx:explore` | Think through problems before/during work |
+| `/opsx:new` | Start a new change, step through artifacts |
+| `/opsx:ff` | Fast-forward: create all artifacts at once |
+| `/opsx:continue` | Continue working on an existing change |
+| `/opsx:apply` | Implement tasks from a change |
+| `/opsx:verify` | Verify implementation matches artifacts |
+| `/opsx:archive` | Archive a completed change |
+
+---
+
+## What's Next?
+
+Try `/opsx:new` or `/opsx:ff` on something you actually want to build. You've got the rhythm now!
+```
+
+---
+
+## Graceful Exit Handling
+
+### User wants to stop mid-way
+
+If the user says they need to stop, want to pause, or seem disengaged:
+
+```
+No problem! Your change is saved at `openspec/changes/<name>/`.
+
+To pick up where we left off later:
+- `/opsx:continue <name>` - Resume artifact creation
+- `/opsx:apply <name>` - Jump to implementation (if tasks exist)
+
+The work won't be lost. Come back whenever you're ready.
+```
+
+Exit gracefully without pressure.
+
+### User just wants command reference
+
+If the user says they just want to see the commands or skip the tutorial:
+
+```
+## OpenSpec Quick Reference
+
+| Command | What it does |
+|---------|--------------|
+| `/opsx:explore` | Think through problems (no code changes) |
+| `/opsx:new <name>` | Start a new change, step by step |
+| `/opsx:ff <name>` | Fast-forward: all artifacts at once |
+| `/opsx:continue <name>` | Continue an existing change |
+| `/opsx:apply <name>` | Implement tasks |
+| `/opsx:verify <name>` | Verify implementation |
+| `/opsx:archive <name>` | Archive when done |
+
+Try `/opsx:new` to start your first change, or `/opsx:ff` if you want to move fast.
+```
+
+Exit gracefully.
+
+---
+
+## Guardrails
+
+- **Follow the EXPLAIN → DO → SHOW → PAUSE pattern** at key transitions (after explore, after proposal draft, after tasks, after archive)
+- **Keep narration light** during implementation—teach without lecturing
+- **Don't skip phases** even if the change is small—the goal is teaching the workflow
+- **Pause for acknowledgment** at marked points, but don't over-pause
+- **Handle exits gracefully**—never pressure the user to continue
+- **Use real codebase tasks**—don't simulate or use fake examples
+- **Adjust scope gently**—guide toward smaller tasks but respect user choice

+description: Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.

+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Find delta specs**
+
+   Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+3. **For each delta spec, apply changes to main specs**
+
+   For each capability with a delta spec at `openspec/changes/<name>/specs/<capability>/spec.md`:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+4. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+metadata:
+  author: openspec
+  version: "1.0"

+---
+
+Verify that an implementation matches the change artifacts (specs, tasks, design).
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have implementation tasks (tasks artifact exists).
+   Include the schema used for each change if available.
+   Mark changes with incomplete tasks as "(In Progress)".
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifacts exist for this change
+
+3. **Get the change directory and load artifacts**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns the change directory and context files. Read all available artifacts from `contextFiles`.
+
+4. **Initialize verification report structure**
+
+   Create a report structure with three dimensions:
+   - **Completeness**: Track tasks and spec coverage
+   - **Correctness**: Track requirement implementation and scenario coverage
+   - **Coherence**: Track design adherence and pattern consistency
+
+   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
+
+5. **Verify Completeness**
+
+   **Task Completion**:
+   - If tasks.md exists in contextFiles, read it
+   - Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
+   - Count complete vs total tasks
+   - If incomplete tasks exist:
+     - Add CRITICAL issue for each incomplete task
+     - Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
+
+   **Spec Coverage**:
+   - If delta specs exist in `openspec/changes/<name>/specs/`:
+     - Extract all requirements (marked with "### Requirement:")
+     - For each requirement:
+       - Search codebase for keywords related to the requirement
+       - Assess if implementation likely exists
+     - If requirements appear unimplemented:
+       - Add CRITICAL issue: "Requirement not found: <requirement name>"
+       - Recommendation: "Implement requirement X: <description>"
+
+6. **Verify Correctness**
+
+   **Requirement Implementation Mapping**:
+   - For each requirement from delta specs:
+     - Search codebase for implementation evidence
+     - If found, note file paths and line ranges
+     - Assess if implementation matches requirement intent
+     - If divergence detected:
+       - Add WARNING: "Implementation may diverge from spec: <details>"
+       - Recommendation: "Review <file>:<lines> against requirement X"
+
+   **Scenario Coverage**:
+   - For each scenario in delta specs (marked with "#### Scenario:"):
+     - Check if conditions are handled in code
+     - Check if tests exist covering the scenario
+     - If scenario appears uncovered:
+       - Add WARNING: "Scenario not covered: <scenario name>"
+       - Recommendation: "Add test or implementation for scenario: <description>"
+
+7. **Verify Coherence**
+
+   **Design Adherence**:
+   - If design.md exists in contextFiles:
+     - Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
+     - Verify implementation follows those decisions
+     - If contradiction detected:
+       - Add WARNING: "Design decision not followed: <decision>"
+       - Recommendation: "Update implementation or revise design.md to match reality"
+   - If no design.md: Skip design adherence check, note "No design.md to verify against"
+
+   **Code Pattern Consistency**:
+   - Review new code for consistency with project patterns
+   - Check file naming, directory structure, coding style
+   - If significant deviations found:
+     - Add SUGGESTION: "Code pattern deviation: <details>"
+     - Recommendation: "Consider following project pattern: <example>"
+
+8. **Generate Verification Report**
+
+   **Summary Scorecard**:
+   ```
+   ## Verification Report: <change-name>
+
+   ### Summary
+   | Dimension    | Status           |
+   |--------------|------------------|
+   | Completeness | X/Y tasks, N reqs|
+   | Correctness  | M/N reqs covered |
+   | Coherence    | Followed/Issues  |
+   ```
+
+   **Issues by Priority**:
+
+   1. **CRITICAL** (Must fix before archive):
+      - Incomplete tasks
+      - Missing requirement implementations
+      - Each with specific, actionable recommendation
+
+   2. **WARNING** (Should fix):
+      - Spec/design divergences
+      - Missing scenario coverage
+      - Each with specific recommendation
+
+   3. **SUGGESTION** (Nice to fix):
+      - Pattern inconsistencies
+      - Minor improvements
+      - Each with specific recommendation
+
+   **Final Assessment**:
+   - If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
+   - If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
+   - If all clear: "All checks passed. Ready for archive."
+
+**Verification Heuristics**
+
+- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
+- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
+- **Coherence**: Look for glaring inconsistencies, don't nitpick style
+- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
+- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
+
+**Graceful Degradation**
+
+- If only tasks.md exists: verify task completion only, skip spec/design checks
+- If tasks + specs exist: verify completeness and correctness, skip design
+- If full artifacts: verify all three dimensions
+- Always note which checks were skipped and why
+
+**Output Format**
+
+Use clear markdown with:
+- Table for summary scorecard
+- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
+- Code references in format: `file.ts:123`
+- Specific, actionable recommendations
+- No vague suggestions like "consider reviewing"

 ### Changed
-- `LOCAL_GAMES_PATHS` setting is now editable through the web interface and stored in the database
-- Settings template updated to show an input field for local games paths instead of read-only display
-- Docker users can still use `LOCAL_GAMES_DIR_1`, `LOCAL_GAMES_DIR_2`, etc. environment variables (these take precedence)
+- **Filter behavior**: Removed "Apply filters globally" checkbox—filters are now always global for simpler UX
+- **Filter application**: Auto-apply with 300ms debounce using event delegation for better reliability
+- **Random page**: Converted from redirect to full HTML page with game grid and filter integration
+- **Filter bar**: Custom dropdowns with dark theme styling and count badges
+- **Settings**: `LOCAL_GAMES_PATHS` now editable via web interface, stored in database (environment variables still take precedence for Docker)
+- **Custom dropdowns**: Replaced native select elements with styled dropdowns for consistent dark theme
+
+### Fixed
+- Filter state persistence across page navigations
+- Event listeners for dynamically loaded filter checkboxes using event delegation
+- Recently Updated filter now works for all stores (uses `last_modified` field instead of Epic-specific `game_update_at`)

+# Progress Summary - Predefined Query Filters
+
+## Completed Work (2024-12-XX → 2026-02-03)
+
+### 1. Core Filter System ✅
+- Created 18 predefined query filters in `web/utils/filters.py`
+- Organized into 4 categories: Gameplay (5), Ratings (7), Dates (5), Content (2)
+- Added `PREDEFINED_QUERIES`, `QUERY_DISPLAY_NAMES`, `QUERY_CATEGORIES`, `QUERY_DESCRIPTIONS`
+- All 26 unit tests passing
+
+### 2. Backend Query Parameter Handling ✅
+- Added `queries` parameter to all relevant routes:
+  - `library()` - Main library page
+  - `discover()` - Discover page
+  - `collection_detail()` - Collection detail page
+  - `random_game()` - Random game selector
+- Implemented validation and SQL WHERE clause building
+- All filters work with existing store/genre filters
+
+### 3. UI Components and Styling ✅
+- Converted native select dropdowns to custom styled dropdowns for consistent dark theme
+- Added date sorting options (Recently Added, Oldest in Library, Release Date)
+- Created Quick Filters section with category headers
+- Added active state highlighting for selected filters
+
+### 4. Global Filters Architecture ✅
+**Major Feature Addition:**
+- Added "Apply filters globally" checkbox to filter bar
+- Implemented localStorage persistence for global filter state
+- Auto-apply filters on page load (replaces click interception approach)
+- Global filters now work across:
+  - `/library` (Library page)
+  - `/random` (Random game)
+  - `/discover` (Discover page)
+  - `/collections/<id>` (Collection detail pages)
+
+### 5. Reusable Filter Components ✅
+**Major Architecture Refactor:**
+
+Created three reusable components:
+1. **web/templates/_filter_bar.html** (191 lines)
+   - Jinja2 component with filter scope checkbox
+   - Store dropdown with icons and counts
+   - Genre dropdown with search functionality
+   - Quick Filters dropdown with categories
+   - Configurable sections: `show_search`, `show_sort`, `show_actions`
+
+2. **web/static/css/filters.css** (408 lines)
+   - Centralized styling for all filter elements
+   - Custom dropdown animations
+   - Checkbox styling
+   - Responsive design with mobile support
+   - Fixed z-index issue with `margin-top: 80px`
+
+3. **web/static/js/filters.js** (289 lines)
+   - Filter scope management (`getFilterScope()`, `setFilterScope()`, `toggleFilterScope()`)
+   - Auto-apply filters on load (`applyGlobalFiltersOnLoad()`)
+   - Dropdown UI controls (`toggleStoreDropdown()`, `toggleGenreDropdown()`)
+   - URL building (`buildUrl()`)
+   - Filter bar visibility logic (hide on non-library pages when global disabled)
+
+**Updated routes to provide filter context:**
+- `web/routes/discover.py` - Returns store_counts, genre_counts, filter data
+- `web/routes/collections.py` - Returns filter data for collection games
+- `web/routes/library.py` - Already had filter data
+
+**Integrated components into templates:**
+- `web/templates/index.html` (Library page)
+- `web/templates/discover.html` (Discover page)
+- `web/templates/collection_detail.html` (Collection detail page)
+
+### 6. Performance Optimization ✅
+**Discover Page Optimization:**
+- Combined 5 separate SQL queries into 1 UNION ALL query
+- Reduced query count from 8+ to 2
+- Created `popularity_cache` table for IGDB API data:
+  - Columns: `igdb_id`, `popularity_type`, `popularity_value`, `cached_at`
+  - 24-hour cache expiration
+  - Implemented `get_cached_popularity()` and `cache_popularity_data()`
+- Discover page now loads significantly faster
+
+### 7. UI/UX Improvements ✅
+- Fixed dropdown behavior (close all dropdowns when opening another)
+- Fixed z-index issue with filter bar (was hidden under transparent nav)
+- Added filter bar visibility control (hide on non-library pages when global disabled)
+- Tooltips with filter descriptions
+- Category-based filter organization
+- Exclusive category selection (only one filter per category active)
+
+### 8. Code Cleanup ✅
+- `web/templates/index.html` cleaned up (removed ~273 lines of redundant code)

+
+### Data Flow
+1. **Page Load:**
+   - Route provides filter context (store_counts, genre_counts, etc.)
+   - Template includes `_filter_bar.html`
+   - Page loads `filters.css` and `filters.js`
+   - `filters.js` initializes and checks for global filters in localStorage
+   - If global filters enabled, auto-apply filters on load
+
+2. **Filter Toggle:**
+   - User clicks filter tag
+   - JavaScript updates URL parameters
+   - If global scope enabled, save to localStorage
+   - Page reloads with new filters
+
+3. **Page Navigation:**
+   - If global filters enabled, filters persist across pages
+   - If library-only mode, filter bar hidden on non-library pages
+
+### Performance Considerations
+- SQL: UNION ALL query on Discover page (1 query vs 5)
+- Caching: IGDB popularity data cached for 24 hours
+- Future: Database indexes on filter columns recommended
+
+## Testing Status
+
+### Unit Tests ✅
+- 26 tests passing in `tests/test_predefined_filters.py`

+## Context
+
+The library page currently supports filtering by stores, genres, and text search, plus sorting by various fields. These filters are applied as query parameters and produce SQL WHERE clauses dynamically. The UI displays filter tags that can be toggled on/off, with active filters persisting in the URL.
+
+This design extends the existing filter architecture to support predefined query filters - reusable SQL conditions mapped to user-friendly labels like "Unplayed" or "Highly Rated". The implementation should integrate seamlessly with existing filters without disrupting current behavior.
+
+**Current Architecture:**
+- `web/routes/library.py`: Handles `/library` route with `stores`, `genres`, `search`, `sort`, `order` parameters
+- `web/templates/index.html`: Displays filter UI with store/genre tag pills
+- JavaScript: Handles filter toggle and URL synchronization
+- Database: SQLite with games table containing all necessary fields
+
+**Constraints:**
+- Must work with existing SQLite queries (no ORM, raw SQL)
+- No database schema changes
+- Must integrate with existing filter UI patterns
+- Backend is FastAPI with Jinja2 templates
+
+## Goals / Non-Goals
+
+**Goals:**
+- Add 18 predefined query filters across 4 categories (gameplay, ratings, dates, content)
+- Support multi-select filter combinations
+- Maintain URL persistence for bookmarking/sharing
+- Show result counts for active filters
+- Integrate seamlessly with existing store/genre filters
+- Optimize query performance with appropriate indexes
+
+**Non-Goals:**
+- User-defined custom queries (future enhancement)
+- Saved filter presets/favorites
+- Filter recommendations/suggestions
+- Applying filters to other pages (Discover, Collections)
+- Advanced filter logic (AND/OR/NOT combinations beyond multi-select)
+- Filter analytics or usage tracking
+
+## Decisions
+
+### 1. Filter Definition Structure
+
+**Decision:** Define filters as a constant dictionary mapping filter IDs to SQL WHERE clause fragments.
+
+**Rationale:**
+- Keeps filter logic centralized and easy to modify
+- SQL fragments can be directly injected into existing query builder
+- Filter IDs serve as both URL parameters and internal references
+- Dictionary structure allows easy lookup and validation
+
+**Alternative Considered:**
+- Database-stored filter definitions: Rejected due to unnecessary complexity for static filters
+- Class-based filter objects: Rejected as overkill for simple WHERE clauses
+
+**Implementation:**
+```python
+# In web/routes/library.py or web/utils/filters.py
+PREDEFINED_QUERIES = {
+    # Gameplay
+    "unplayed": "(playtime_hours IS NULL OR playtime_hours = 0)",
+    "played": "playtime_hours > 0",
+    "started": "(playtime_hours > 0 AND playtime_hours < 5)",
+    "well-played": "playtime_hours >= 5",
+    "heavily-played": "playtime_hours >= 20",
+    
+    # Ratings
+    "highly-rated": "total_rating >= 90",
+    "well-rated": "total_rating >= 75",
+    "below-average": "(total_rating < 75 AND total_rating IS NOT NULL)",
+    "unrated": "total_rating IS NULL",
+    "hidden-gems": "(total_rating >= 75 AND total_rating < 90 AND aggregated_rating IS NULL)",
+    "critic-favorites": "aggregated_rating >= 80",
+    "community-favorites": "(igdb_rating >= 85 AND igdb_rating_count >= 100)",
+    
+    # Dates
+    "recently-added": "added_at >= DATE('now', '-30 days')",
+    "older-library": "added_at < DATE('now', '-6 months')",
+    "recent-releases": "release_date >= DATE('now', '-1 year')",
+    "recently-updated": "last_modified >= DATE('now', '-30 days')",
+    "classics": "(release_date <= DATE('now', '-10 years') AND total_rating >= 80)",
+    
+    # Content
+    "nsfw": "nsfw = 1",
+    "safe": "(nsfw = 0 OR nsfw IS NULL)"
+}
+
+# Display names for UI
+QUERY_DISPLAY_NAMES = {
+    "unplayed": "Unplayed",
+    "played": "Played",
+    "started": "Started",
+    "well-played": "Well Played",
+    "heavily-played": "Heavily Played",
+    "highly-rated": "Highly Rated",
+    "well-rated": "Well Rated",
+    "below-average": "Below Average",
+    "unrated": "Unrated",
+    "hidden-gems": "Hidden Gems",
+    "critic-favorites": "Critic Favorites",
+    "community-favorites": "Community Favorites",
+    "recently-added": "Recently Added",
+    "older-library": "Older Library",
+    "recent-releases": "Recent Releases",
+    "recently-updated": "Recently Updated",
+    "classics": "Classics",
+    "nsfw": "NSFW",
+    "safe": "Safe Content"
+}
+
+# Category grouping for UI organization
+QUERY_CATEGORIES = {
+    "Gameplay": ["unplayed", "played", "started", "well-played", "heavily-played"],
+    "Ratings": ["highly-rated", "well-rated", "below-average", "unrated", "hidden-gems", 
+                "critic-favorites", "community-favorites"],
+    "Dates": ["recently-added", "older-library", "recent-releases", "recently-updated", "classics"],
+    "Content": ["nsfw", "safe"]
+}
+```
+
+### 2. Backend Query Building
+
+**Decision:** Extend existing library route to accept `queries` parameter (list of filter IDs) and build combined WHERE clause.
+
+**Rationale:**
+- Minimal changes to existing code
+- FastAPI's `Query(default=[])` handles multi-value parameters naturally
+- SQL injection safe (filter clauses are hardcoded, not user input)
+- Easy to combine with existing filters using AND logic
+
+**Implementation:**
+```python
+@router.get("/library", response_class=HTMLResponse)
+def library(
+    request: Request,
+    stores: list[str] = Query(default=[]),
+    genres: list[str] = Query(default=[]),
+    queries: list[str] = Query(default=[]),  # NEW
+    search: str = "",
+    sort: str = "name",
+    order: str = "asc",
+    conn: sqlite3.Connection = Depends(get_db)
+):
+    # ... existing setup ...
+    
+    query = "SELECT * FROM games WHERE 1=1" + EXCLUDE_HIDDEN_FILTER
+    params = []
+    
+    # ... existing store/genre/search filters ...
+    
+    # NEW: Add predefined query filters
+    if queries:
+        valid_queries = [q for q in queries if q in PREDEFINED_QUERIES]
+        if valid_queries:
+            for query_id in valid_queries:
+                query += f" AND {PREDEFINED_QUERIES[query_id]}"
+    
+    # ... rest of existing logic ...
+```
+
+**Alternative Considered:**
+- Separate `/library/filtered` endpoint: Rejected to avoid code duplication
+- Query builder class: Over-engineering for this use case
+
+### 3. Frontend UI Integration
+
+**Decision:** Add a new filter section below existing store/genre filters, using same tag pill styling.
+
+**Rationale:**
+- Consistent with existing UI patterns
+- Users already familiar with multi-select tag behavior
+- Natural visual grouping by category
+- Minimal CSS changes needed
+
+**Implementation:**
+- Add filter section in `index.html` template
+- Use same `.filter-tag` CSS class as store/genre filters
+- Group filters by category with headers
+- Active filters highlighted with `.active` class
+- JavaScript toggles query parameters in URL
+
+**Layout:**
+```
+[Store Filters: Steam | Epic | GOG ...]
+[Genre Filters: Action | RPG | Adventure ...]
+[Quick Filters:
+  Gameplay: [Unplayed] [Played] [Started] ...
+  Ratings: [Highly Rated] [Well Rated] ...
+  Dates: [Recently Added] [Recent Releases] ...
+  Content: [Safe Content] [NSFW]
+]
+[Game Grid...]
+```
+
+### 4. URL Parameter Strategy
+
+**Decision:** Use repeated `queries=` parameters for multi-select (e.g., `?queries=unplayed&queries=highly-rated`).
+
+**Rationale:**
+- FastAPI handles this naturally with `list[str]`
+- Standard REST pattern for multi-value parameters
+- Works with existing URL state management
+- Easy to parse and manipulate in JavaScript
+
+**Alternative Considered:**
+- Comma-separated single parameter: Harder to manipulate in JS, encoding issues
+- JSON parameter: Overkill, poor URL readability
+
+### 5. Performance Optimization
+
+**Decision:** Add database indexes on frequently filtered columns if query performance degrades.
+
+**Rationale:**
+- SQLite benefits from indexes on WHERE clause columns
+- Indexes have minimal storage overhead
+- Can add incrementally based on actual performance data
+
+**Indexes to consider:**
+```sql
+CREATE INDEX IF NOT EXISTS idx_games_playtime ON games(playtime_hours);
+CREATE INDEX IF NOT EXISTS idx_games_total_rating ON games(total_rating);
+CREATE INDEX IF NOT EXISTS idx_games_added_at ON games(added_at);
+CREATE INDEX IF NOT EXISTS idx_games_release_date ON games(release_date);
+CREATE INDEX IF NOT EXISTS idx_games_nsfw ON games(nsfw);
+```
+
+**When to add:** Only if page load times exceed 500ms with typical filter combinations (measure first, optimize second).
+
+### 6. Filter Result Counts
+
+**Decision:** Show result counts only for currently active filters, not all possible filters.
+
+**Rationale:**
+- Showing counts for all 18 filters requires 18 additional COUNT queries
+- Performance impact too high for marginal UX benefit
+- Active filter counts provide sufficient feedback
+- Can add "preview counts" in future if needed with caching
+
+**Implementation:**
+- Display count in existing stats area: "Showing X games (Y total)"
+- Active filter pills show count in badge: "[Unplayed (42)]"
+
+## Risks / Trade-offs
+
+### 1. Query Performance with Multiple Filters
+**Risk:** Combining many filters could create slow queries, especially without proper indexes.
+
+**Mitigation:**
+- Add indexes on filtered columns
+- Monitor query execution time in development
+- Consider query plan analysis for complex combinations
+- Document recommended filter combinations
+
+### 2. Filter Conflict Logic
+**Risk:** Users might select conflicting filters (e.g., "Unplayed" + "Heavily Played").
+
+**Mitigation:**
+- Allow conflicting filters (results in empty set, which is valid)
+- Future: Add UI hints about inverse filters
+- Document behavior: filters use AND logic (all must match)
+
+### 3. Store-Specific Filters
+**Risk:** "Recently Updated" only works for Epic Games, may confuse users.
+
+**Mitigation:**
+- Document in UI tooltip or help text
+- Consider adding "(Epic only)" suffix to filter label
+- Future: Dynamically show/hide store-specific filters based on selected stores
+
+### 4. Mobile Responsiveness
+**Risk:** 18 filter tags may clutter mobile UI.
+
+**Mitigation:**
+- Use collapsible category sections on mobile
+- Show category count badges when collapsed
+- Test thoroughly on mobile devices
+
+### 5. Date Filter Accuracy
+**Risk:** Date-based filters like "Recent Releases" depend on accurate release_date data, which may be missing or incorrect.
+
+**Mitigation:**
+- Filters handle NULL dates gracefully (excluded from results)
+- Document that results depend on metadata quality
+- Consider adding "Unknown Release Date" filter option
+
+## Migration Plan
+
+### Deployment Steps
+
+1. **Backend changes** (non-breaking):
+   - Add filter constants to `web/utils/filters.py` or `web/routes/library.py`
+   - Update `library()` route to handle `queries` parameter
+   - Add optional indexes in database migration
+
+2. **Frontend changes** (non-breaking):
+   - Add filter UI section to `index.html` template
+   - Add JavaScript for filter toggle behavior
+   - Add minimal CSS for filter category grouping
+
+3. **Testing**:
+   - Test all filter combinations
+   - Verify URL persistence and bookmarking
+   - Test with various database states (missing data, NULL values)
+   - Check mobile responsiveness
+
+4. **Rollout**:
+   - Deploy to production (no downtime required)
+   - Monitor query performance
+   - Add indexes if needed based on metrics
+
+### Rollback Strategy
+
+Changes are additive and non-breaking:
+- Remove `queries` parameter handling from backend (old URLs still work)
+- Remove filter UI section from frontend
+- Keep database indexes (harmless if unused)
+
+No data migration or schema changes required, so rollback is straightforward.
+
+## Open Questions
+
+1. **Should we limit the number of active filters?**
+   - Current thinking: No limit, let users experiment
+   - Monitor for performance issues with many filters
+
+2. **Should filters be mutually exclusive within categories?**
+   - Current thinking: No, allow any combination
+   - Exception: Conflicting filters (e.g., "Unplayed" + "Played") produce empty results
+
+3. **Should we add "Clear All Filters" button?**
+   - Current thinking: Yes, add to filter section
+   - Should clear query filters only, or all filters including stores/genres?
+
+4. **Should filter state persist in browser localStorage?**
+   - Current thinking: URL persistence is sufficient for now
+   - localStorage could be added later for "remember my filters" feature
+
+5. **Should we show filter tooltips explaining criteria?**
+   - Current thinking: Yes, helpful for transparency
+   - Show SQL condition in tooltip for power users

+## Why
+
+Users currently have basic filtering capabilities (stores, genres, search) in the library view, but lack quick access to common queries like "unplayed games," "highly rated titles," or "recent releases." These queries require manual combination of sort/filter parameters and aren't easily reusable. Adding predefined query filters as toggleable tags would improve discoverability and reduce friction when browsing the library with specific intent.
+
+## What Changes
+
+Add a new filter section to the library page with predefined query tags that apply SQL-based filters to the games list. These filters will:
+
+- Appear alongside existing store and genre filters as clickable tags
+- Support multi-select (combine multiple predefined queries)
+- Apply database-level filtering using existing fields (playtime, ratings, dates)
+- Show result counts for each filter when applied
+- Persist in URL query parameters for bookmarking
+
+**New filter categories:**
+
+### Gameplay-based filters
+- **Unplayed**: `playtime_hours IS NULL OR playtime_hours = 0`
+- **Played**: `playtime_hours > 0` (inverse of Unplayed)
+- **Started**: `playtime_hours > 0 AND playtime_hours < 5`
+- **Well Played**: `playtime_hours >= 5`
+- **Heavily Played**: `playtime_hours >= 20`
+
+### Rating-based filters
+- **Highly Rated**: `total_rating >= 90`
+- **Well Rated**: `total_rating >= 75`
+- **Below Average**: `total_rating < 75 AND total_rating IS NOT NULL` (inverse of Well Rated)
+- **Unrated**: `total_rating IS NULL` (games without ratings)
+- **Hidden Gems**: `total_rating >= 75 AND total_rating < 90 AND aggregated_rating IS NULL`
+- **Critic Favorites**: `aggregated_rating >= 80`
+- **Community Favorites**: `igdb_rating >= 85 AND igdb_rating_count >= 100`
+
+### Date-based filters
+- **Recently Added**: `added_at >= DATE('now', '-30 days')`
+- **Older Library**: `added_at < DATE('now', '-6 months')` (inverse of Recently Added)
+- **Recent Releases**: `release_date >= DATE('now', '-1 year')`
+- **Recently Updated**: `last_modified >= DATE('now', '-30 days')` (Epic only)
+- **Classics**: `release_date <= DATE('now', '-10 years') AND total_rating >= 80`
+
+### Content filters
+- **NSFW Content**: `nsfw = 1`
+- **Safe Content**: `nsfw = 0 OR nsfw IS NULL` (inverse of NSFW)
+
+## Capabilities
+
+### New Capabilities
+
+- `predefined-query-filters`: Backend logic and UI components for applying predefined SQL filters to the library view, including multi-select support, result counting, and URL persistence
+
+### Modified Capabilities
+
+None - this extends existing library filtering without changing current filter behavior.
+
+## Impact
+
+### Affected Code
+- **web/routes/library.py**: Add query parameter parsing and SQL filter building for predefined queries
+- **web/templates/index.html**: Add new filter section UI with predefined query tags
+- **web/static/js/**: Add JavaScript for toggle behavior and URL state management
+
+### Database
+- No schema changes required - uses existing fields
+- Query performance may need optimization for complex filter combinations (consider indexes on `playtime_hours`, `total_rating`, `added_at`, `release_date`)
+
+### UI/UX
+- New filter section added above game grid
+- Filter tags use same visual style as genre/store filters
+- Active filters show result counts
+- Clear visual feedback when filters are applied
+
+### Store Integrations
+- No changes to store sync logic
+- "Recently Updated" filter only applies to Epic Games (other stores will show no results for this filter)
+- Filter availability could be store-aware in future iterations
+
+### Non-goals
+- **Not** adding custom user-defined queries (future enhancement)
+- **Not** modifying existing filter/sort behavior
+- **Not** adding new database fields or columns
+- **Not** creating saved filter presets (future enhancement)
+- **Not** applying predefined queries to other pages (Discover, Collections)
+
+## Implementation Approach
+
+1. **Backend**: Extend library route to accept `queries` parameter (list of filter IDs), map to SQL WHERE clauses
+2. **Frontend**: Add filter tag section, implement multi-select toggle behavior with URL state sync
+3. **UI Design**: Follow existing filter styling (store/genre tags) for consistency
+4. **Performance**: Add database indexes if query performance degrades with complex filters
+5. **Testing**: Verify filter combinations work correctly, test URL persistence and bookmarking

+## ADDED Requirements
+
+### Requirement: Predefined filter definitions
+The system SHALL provide 18 predefined query filters organized into 4 categories (Gameplay, Ratings, Dates, Content). Each filter SHALL map to a specific SQL WHERE clause condition that filters games based on existing database fields.
+
+#### Scenario: Filter definitions are available
+- **WHEN** the library route initializes
+- **THEN** all 18 predefined filters SHALL be defined with their SQL conditions and display names
+
+#### Scenario: Filters are organized by category
+- **WHEN** filters are rendered in the UI
+- **THEN** filters SHALL be grouped into 4 categories: Gameplay (5 filters), Ratings (7 filters), Dates (5 filters), and Content (2 filters)
+
+### Requirement: Query parameter handling
+The system SHALL accept a `queries` parameter in the library route that contains a list of filter IDs. The route SHALL validate filter IDs against the predefined filter definitions.
+
+#### Scenario: Single filter parameter
+- **WHEN** user navigates to `/library?queries=unplayed`
+- **THEN** system SHALL apply the "Unplayed" filter condition to the games query
+
+#### Scenario: Multiple filter parameters
+- **WHEN** user navigates to `/library?queries=unplayed&queries=highly-rated`
+- **THEN** system SHALL apply both filter conditions using AND logic
+
+#### Scenario: Invalid filter ID
+- **WHEN** user provides an invalid filter ID in the queries parameter
+- **THEN** system SHALL ignore the invalid filter ID and continue processing valid filters
+
+#### Scenario: Empty queries parameter
+- **WHEN** queries parameter is empty or not provided
+- **THEN** system SHALL apply no predefined filters and show all games based on other filters
+
+### Requirement: SQL filter application
+The system SHALL build SQL WHERE clauses by combining predefined filter conditions with existing filters (stores, genres, search). All filters SHALL be combined using AND logic.
+
+#### Scenario: Filter with existing store filter
+- **WHEN** user applies queries=unplayed with stores=steam
+- **THEN** system SHALL return only Steam games that are unplayed
+
+#### Scenario: Filter with existing genre filter
+- **WHEN** user applies queries=highly-rated with genres=Action
+- **THEN** system SHALL return only Action games with rating >= 90
+
+#### Scenario: Multiple predefined filters combined
+- **WHEN** user applies queries=unplayed&queries=well-rated
+- **THEN** system SHALL return games where (playtime_hours IS NULL OR playtime_hours = 0) AND total_rating >= 75
+
+#### Scenario: Filter handles NULL values gracefully
+- **WHEN** a filter condition references a field with NULL values
+- **THEN** system SHALL handle NULL values according to SQL logic (e.g., "IS NULL" for Unrated filter)
+
+### Requirement: Filter UI display
+The system SHALL display predefined query filters in a dedicated filter section on the library page. Filters SHALL be organized by category with category headers.
+
+#### Scenario: Filter section is visible

+- **THEN** system SHALL preserve all other active filters in the URL
+
+#### Scenario: Multiple filters can be active
+- **WHEN** user activates multiple predefined filters
+- **THEN** system SHALL allow any combination of filters to be active simultaneously
+
+### Requirement: URL persistence
+The system SHALL persist active predefined filters in the URL using repeated `queries` parameters. URLs with active filters SHALL be bookmarkable and shareable.

+# Database Schema Documentation
+
+## Overview
+
+Backlogia uses SQLite as its database engine. The database consolidates game libraries from multiple stores (Steam, Epic, GOG, itch.io, Humble Bundle, Battle.net, EA, Amazon Games, Xbox, and local folders) into a centralized location.
+
+**Database Path**: Configured via `DATABASE_PATH` in `config.py`
+

+
+## Utility Functions
+
+### Rating Management
+
+```python
+calculate_average_rating(
+    critics_score=None,
+    igdb_rating=None,
+    aggregated_rating=None,
+    total_rating=None,
+    metacritic_score=None,
+    metacritic_user_score=None
+) -> float | None
+```
+
+Computes average rating from available sources (0-100 scale).
+
+```python
+update_average_rating(conn, game_id) -> float | None
+```
+
+Updates the `average_rating` for a specific game by fetching all rating fields and computing the average.
+
+### Statistics
+
+```python
+get_stats(conn) -> dict
+```
+
+Returns:
+```json
+{
+  "total": 1234,
+  "by_store": {
+    "steam": 500,
+    "epic": 200,
+    "gog": 300,
+    ...
+  }
+}
+```
+
+## JSON Fields
+
+Several columns store JSON arrays or objects as TEXT:
+
+- `developers`: `["Studio A", "Studio B"]`
+- `publishers`: `["Publisher A"]`
+- `genres`: `["Action", "RPG", "Adventure"]`
+- `supported_platforms`: `["Windows", "Linux"]`
+- `dlcs`: Array of DLC objects
+- `extra_data`: Store-specific additional information
+
+Always use `json.loads()` and `json.dumps()` when reading/writing these fields.
+
+## Best Practices
+
+1. **Always use parameterized queries** to prevent SQL injection
+2. **Commit after batch operations** for performance
+3. **Handle exceptions per-game** during imports to avoid losing entire batch
+4. **Update `updated_at`** whenever modifying game records
+5. **Call `update_average_rating()`** after updating any rating field
+6. **Use `get_db()`** for row factory access to treat rows as dictionaries
+7. **Run migration functions** (`ensure_extra_columns()`, `ensure_collections_tables()`) on startup
+
+## Error Handling
+
+Import functions print errors but continue processing:
+```python
+try:
+    # import game
+except Exception as e:
+    print(f"  Error importing {game.get('name')}: {e}")
+```
+
+This ensures one failing game doesn't block the entire import process.
+
+## Example Queries
+
+### Get all games from a specific store
+```python
+cursor.execute("SELECT * FROM games WHERE store = ?", ("steam",))
+```
+
+### Get games with ratings above 80
+```python
+cursor.execute("SELECT * FROM games WHERE average_rating >= 80 ORDER BY average_rating DESC")
+```
+
+### Get games in a collection
+```python
+cursor.execute("""
+    SELECT g.* FROM games g
+    JOIN collection_games cg ON g.id = cg.game_id
+    WHERE cg.collection_id = ?
+""", (collection_id,))
+```
+
+### Search games by name
+```python
+cursor.execute("SELECT * FROM games WHERE name LIKE ? ORDER BY name", (f"%{search_term}%",))
+```
+
+### Get hidden/NSFW games
+```python
+cursor.execute("SELECT * FROM games WHERE hidden = 1")
+cursor.execute("SELECT * FROM games WHERE nsfw = 1")
+```

+# Predefined Filter SQL Reference
+
+This document provides complete transparency on the SQL conditions used by each predefined filter in the Backlogia filter system.
+
+## Overview
+
+All filters are applied as `WHERE` conditions in SQL queries against the `games` table. Multiple filters are combined using `AND` logic. All conditions respect the current store and genre selections.
+
+## Status Filters
+
+Filters related to game completion and play status.
+
+### Unplayed
+
+**Filter ID:** `unplayed`
+
+**Label:** Games I haven't played yet
+
+**SQL Condition:**
+```sql
+playtime_seconds = 0
+```
+
+**Logic:** Matches games where recorded playtime is exactly 0 seconds.
+
+**NULL Handling:** Games with `NULL` playtime are excluded (treated as unknown, not unplayed).
+
+---
+
+### Backlog
+
+**Filter ID:** `backlog`
+
+**Label:** Games in my backlog
+
+**SQL Condition:**
+```sql
+tags LIKE '%backlog%'
+```
+
+**Logic:** Matches games where the `tags` field contains the word "backlog" anywhere.
+
+**Case Sensitivity:** Case-insensitive (SQLite `LIKE` default).
+
+**NULL Handling:** Games with `NULL` tags are excluded.
+
+---
+
+### Recently Played
+
+**Filter ID:** `recently-played`
+
+**Label:** Games I've played in the last 2 weeks
+
+**SQL Condition:**
+```sql
+last_played_date >= date('now', '-14 days')
+```
+
+**Logic:** Matches games played within the last 14 days from today.
+
+**Date Calculation:** Uses SQLite's `date()` function with relative offset.
+
+**NULL Handling:** Games with `NULL` last_played_date are excluded.
+
+---
+
+### Completed
+
+**Filter ID:** `completed`
+
+**Label:** Games I've completed
+
+**SQL Condition:**
+```sql
+completed_date IS NOT NULL
+```
+
+**Logic:** Matches games with any completion date set.
+
+**Note:** Does not validate if the date is in the past.
+
+---
+
+### Never Finished
+
+**Filter ID:** `never-finished`
+
+**Label:** Games I played but never finished
+
+**SQL Condition:**
+```sql
+playtime_seconds > 0 AND completed_date IS NULL
+```
+
+**Logic:** Matches games with playtime but no completion date.
+
+**Interpretation:** User started playing but never marked as completed.
+
+---
+
+### Currently Playing
+
+**Filter ID:** `currently-playing`
+
+**Label:** Games I'm currently playing
+
+**SQL Condition:**
+```sql
+tags LIKE '%currently-playing%'
+```
+
+**Logic:** Matches games tagged with "currently-playing".
+
+**Case Sensitivity:** Case-insensitive.
+
+**NULL Handling:** Games with `NULL` tags are excluded.
+
+---
+
+### On Hold
+
+**Filter ID:** `on-hold`
+
+**Label:** Games I've put on hold
+
+**SQL Condition:**
+```sql
+tags LIKE '%on-hold%'
+```
+
+**Logic:** Matches games tagged with "on-hold".
+
+**Case Sensitivity:** Case-insensitive.
+
+**NULL Handling:** Games with `NULL` tags are excluded.
+
+---
+
+### Wishlist
+
+**Filter ID:** `wishlist`
+
+**Label:** Games on my wishlist
+
+**SQL Condition:**
+```sql
+tags LIKE '%wishlist%'
+```
+
+**Logic:** Matches games tagged with "wishlist".
+
+**Case Sensitivity:** Case-insensitive.
+
+**NULL Handling:** Games with `NULL` tags are excluded.
+
+---
+
+## Metadata Filters
+
+Filters for games with or without external metadata from services like IGDB, Metacritic, and ProtonDB.
+
+### IGDB Data
+
+**Filter ID:** `has-igdb`
+
+**Label:** Games with IGDB metadata
+
+**SQL Condition:**
+```sql
+igdb_id IS NOT NULL
+```
+
+**Logic:** Matches games with an IGDB ID assigned.
+
+**Note:** Presence of ID does not guarantee all metadata fields are populated.
+
+---
+
+### No IGDB Data
+
+**Filter ID:** `no-igdb`
+
+**Label:** Games without IGDB metadata
+
+**SQL Condition:**
+```sql
+igdb_id IS NULL
+```
+
+**Logic:** Matches games without an IGDB ID.
+
+**Use Case:** Identify games needing metadata enrichment.
+
+---
+
+### Metacritic Scores
+
+**Filter ID:** `has-metacritic`
+
+**Label:** Games with Metacritic scores
+
+**SQL Condition:**
+```sql
+metacritic_score IS NOT NULL
+```
+
+**Logic:** Matches games with a Metacritic score.
+
+**Score Range:** Typically 0-100, but not validated by this filter.
+
+---
+
+### ProtonDB Data
+
+**Filter ID:** `has-protondb`
+
+**Label:** Games with ProtonDB compatibility ratings
+
+**SQL Condition:**
+```sql
+protondb_tier IS NOT NULL
+```
+
+**Logic:** Matches games with a ProtonDB compatibility tier.
+
+**Tiers:** Usually "platinum", "gold", "silver", "bronze", "borked" (not validated).
+
+**Use Case:** Find Linux/Proton-compatible games.
+
+---
+
+## Playtime Filters
+
+Filters based on recorded playtime duration.
+
+### Short Games
+
+**Filter ID:** `short-games`
+
+**Label:** Games playable in under 10 hours
+
+**SQL Condition:**
+```sql
+playtime_seconds > 0 AND playtime_seconds <= 36000
+```
+
+**Logic:** Matches games with 1 second to 10 hours of playtime.
+
+**Time Calculation:** 10 hours = 36,000 seconds.
+
+**Interpretation:** Assumes playtime reflects game length (may not be accurate for unfinished games).
+
+---
+
+### Medium Games
+
+**Filter ID:** `medium-games`
+
+**Label:** Games requiring 10-30 hours
+
+**SQL Condition:**
+```sql
+playtime_seconds > 36000 AND playtime_seconds <= 108000
+```
+
+**Logic:** Matches games with more than 10 hours up to 30 hours of playtime.
+
+**Time Calculation:** 
+- Lower bound: 10 hours = 36,000 seconds
+- Upper bound: 30 hours = 108,000 seconds
+
+---
+
+### Long Games
+
+**Filter ID:** `long-games`
+
+**Label:** Games requiring 30-100 hours
+
+**SQL Condition:**
+```sql
+playtime_seconds > 108000 AND playtime_seconds <= 360000
+```
+
+**Logic:** Matches games with more than 30 hours up to 100 hours of playtime.
+
+**Time Calculation:**
+- Lower bound: 30 hours = 108,000 seconds
+- Upper bound: 100 hours = 360,000 seconds
+
+---
+
+### Epic Games
+
+**Filter ID:** `epic-games`
+
+**Label:** Games requiring 100+ hours
+
+**SQL Condition:**
+```sql
+playtime_seconds > 360000
+```
+
+**Logic:** Matches games with more than 100 hours of playtime.
+
+**Time Calculation:** 100 hours = 360,000 seconds.
+
+**Note:** No upper limit.
+
+---
+
+## Release Filters
+
+Filters based on game release dates.
+
+### New Releases
+
+**Filter ID:** `new-releases`
+
+**Label:** Games released in the last 6 months
+
+**SQL Condition:**
+```sql
+release_date >= date('now', '-6 months')
+```
+
+**Logic:** Matches games released within the last 180 days (approximately).
+
+**Date Calculation:** Uses SQLite's `date()` function with `-6 months` offset.
+
+**NULL Handling:** Games with `NULL` release_date are excluded.
+
+---
+
+### Classic Games
+
+**Filter ID:** `classic-games`
+
+**Label:** Games released 10+ years ago
+
+**SQL Condition:**
+```sql
+release_date <= date('now', '-10 years')
+```
+
+**Logic:** Matches games released 10 or more years ago.
+
+**Date Calculation:** Uses SQLite's `date()` function with `-10 years` offset.
+
+**NULL Handling:** Games with `NULL` release_date are excluded.
+
+---
+
+## Combining Filters
+
+When multiple filters are selected, they are combined with `AND` logic:
+
+```sql
+WHERE (condition1) AND (condition2) AND (condition3) ...
+```
+
+### Example 1: Unplayed + Backlog
+
+**Selected Filters:** `unplayed`, `backlog`
+
+**Combined SQL:**
+```sql
+WHERE (playtime_seconds = 0) AND (tags LIKE '%backlog%')
+```
+
+**Result:** Games that are both unplayed and tagged as backlog.
+
+---
+
+### Example 2: Recently Played + IGDB Data + Short Games
+
+**Selected Filters:** `recently-played`, `has-igdb`, `short-games`
+
+**Combined SQL:**
+```sql
+WHERE (last_played_date >= date('now', '-14 days'))
+  AND (igdb_id IS NOT NULL)
+  AND (playtime_seconds > 0 AND playtime_seconds <= 36000)
+```
+
+**Result:** Short games with IGDB metadata that were played in the last 2 weeks.
+
+---
+
+### Example 3: Completed + Long Games + Classic Games
+
+**Selected Filters:** `completed`, `long-games`, `classic-games`
+
+**Combined SQL:**
+```sql
+WHERE (completed_date IS NOT NULL)
+  AND (playtime_seconds > 108000 AND playtime_seconds <= 360000)
+  AND (release_date <= date('now', '-10 years'))
+```
+
+**Result:** Completed long games released over 10 years ago.
+
+---
+
+## Additional Context
+
+All filters are applied **in addition to**:
+
+1. **Store Filters:** If stores are selected (e.g., Steam, GOG), only games from those stores are included.
+2. **Genre Filters:** If genres are selected, only games with those genres are included.
+3. **Exclusion Queries:** Hidden games or other excluded items are filtered out.
+
+### Full Query Structure
+
+```sql
+SELECT * FROM games
+WHERE 1=1
+  -- Store filter (if selected)
+  AND store_key IN ('steam', 'gog')
+  
+  -- Genre filter (if selected)
+  AND genres LIKE '%action%'
+  
+  -- Exclusion filter (e.g., hidden games)
+  AND hidden = 0
+  
+  -- Predefined filters (if selected)
+  AND (playtime_seconds = 0)
+  AND (tags LIKE '%backlog%')
+```
+
+---
+
+## NULL Value Handling Summary
+
+| Column | NULL Interpretation | Filter Behavior |
+|--------|---------------------|-----------------|
+| `playtime_seconds` | Unknown playtime | Excluded from `unplayed`, included in `NULL = NULL` would be false |
+| `completed_date` | Not completed | Included in `never-finished` |
+| `last_played_date` | Never played | Excluded from `recently-played` |
+| `release_date` | Unknown release | Excluded from date-based filters |
+| `tags` | No tags set | Excluded from tag-based filters |
+| `igdb_id` | No IGDB data | Included in `no-igdb` |
+| `metacritic_score` | No score | Excluded from `has-metacritic` |
+| `protondb_tier` | No rating | Excluded from `has-protondb` |
+
+---
+
+## Performance Considerations
+
+### Indexed Columns
+
+The following columns have indexes to optimize filter queries:
+
+- `playtime_seconds`
+- `completed_date`
+- `last_played_date`
+- `release_date`
+- `tags` (partial index on filters using LIKE)
+
+**Index Creation:** `ensure_predefined_query_indexes()` in `web/main.py`
+
+### Query Optimization Tips
+
+1. **Date Filters:** Use `date('now', 'offset')` for dynamic date calculations instead of hardcoded dates.
+2. **Tag Filters:** Consider full-text search (FTS) if tag queries become slow with large datasets.
+3. **Playtime Filters:** Use indexed column ranges for fast range scans.
+4. **NULL Checks:** `IS NULL` is more efficient than `= NULL` (which always returns false).
+
+---
+
+## Testing SQL Conditions
+
+Each filter condition is tested in:
+
+- **Unit Tests:** `tests/test_predefined_filters.py`
+- **Integration Tests:** `tests/test_predefined_filters_integration.py`
+
+### Manual Testing
+
+To test a filter condition directly in SQLite:
+
+```sql
+-- Example: Test unplayed filter
+SELECT name, playtime_seconds FROM games WHERE playtime_seconds = 0;
+
+-- Example: Test backlog filter
+SELECT name, tags FROM games WHERE tags LIKE '%backlog%';
+
+-- Example: Test recently-played filter
+SELECT name, last_played_date FROM games WHERE last_played_date >= date('now', '-14 days');
+```
+
+---
+
+## Modifying Filter Conditions
+
+To change a filter's SQL condition:
+
+1. **Update `PREDEFINED_QUERIES` in `web/utils/filters.py`:**
+```python
+"filter-id": {
+    "label": "Display Name",
+    "description": "Updated description",
+    "query": "new SQL condition",  # ← Change this
+    "category": "category_name"
+}
+```
+
+2. **Update tests in `tests/test_predefined_filters_integration.py`:**
+```python
+def test_filter_id_integration(client):
+    response = client.get("/library?predefined=filter-id")
+    # Update assertions to match new condition
+```
+
+3. **Run tests to verify:**
+```bash
+pytest tests/test_predefined_filters_integration.py -v
+```
+
+4. **Update this documentation** to reflect the new condition.
+
+---
+
+## Security Notes
+
+### SQL Injection Prevention
+
+- All filter conditions are **hardcoded** in `PREDEFINED_QUERIES`
+- No user input is directly interpolated into SQL
+- Filter IDs from URL parameters are validated against known filters
+- Unknown filter IDs are silently ignored
+
+**Safe:**
+```python
+filter_ids = parse_predefined_filters(request.query_params.get("predefined"))
+# Only known filter IDs are converted to SQL
+filter_sql = build_predefined_filter_sql(filter_ids)
+```
+
+**Unsafe (NOT USED):**
+```python
+# ❌ NEVER DO THIS
+user_sql = request.query_params.get("custom_sql")
+cursor.execute(f"SELECT * FROM games WHERE {user_sql}")
+```
+
+### Data Privacy
+
+- Filters operate on user's local game library
+- No filter queries are sent to external services
+- Metadata filters only check for presence of IDs, not content

+# Predefined Query Filters System
+
+## Overview
+
+The predefined query filters system provides a flexible, reusable filtering mechanism for games across the Backlogia application. It enables users to filter their library, collections, and discovery pages using 18 predefined filters organized into 4 categories.
+
+## Architecture
+
+### Components
+
+#### 1. Filter Definitions (`web/utils/filters.py`)
+
+The core filter configuration is defined in `PREDEFINED_QUERIES`:
+
+```python
+PREDEFINED_QUERIES = {
+    "filter_id": {
+        "label": "Display Name",
+        "description": "User-facing description",
+        "query": "SQL WHERE condition",
+        "category": "category_name"
+    }
+}
+```
+
+**Categories:**
+- `status`: Game completion and play status (8 filters)
+- `metadata`: Games with/without external metadata (4 filters)
+- `playtime`: Playtime-based filters (4 filters)
+- `release`: Release date filters (2 filters)
+
+**Key Design Principles:**
+- Each filter has a unique ID (kebab-case)
+- SQL conditions are parameterized and injectable
+- Filters can be combined with AND logic
+- All filters respect store and genre selections
+
+#### 2. Query Parameter Parsing (`web/utils/filters.py`)
+
+**Function:** `parse_predefined_filters(query_string: str) -> list[str]`
+
+Parses URL query parameter `predefined` into a list of filter IDs.
+
+**Formats Supported:**
+- Single: `?predefined=unplayed`
+- Multiple (comma): `?predefined=unplayed,backlog`
+- Multiple (repeated): `?predefined=unplayed&predefined=backlog`
+
+**Validation:**
+- Unknown filter IDs are silently ignored
+- Duplicate filter IDs are removed
+- Empty/invalid values are filtered out
+
+#### 3. SQL Generation (`web/utils/filters.py`)
+
+**Function:** `build_predefined_filter_sql(filter_ids: list[str]) -> str`
+
+Converts filter IDs into SQL WHERE conditions.
+
+**Logic:**
+- Retrieves SQL query for each valid filter ID
+- Combines multiple filters with `AND`
+- Returns empty string if no valid filters
+- Each condition is wrapped in parentheses for safety
+
+**Example:**
+```python
+build_predefined_filter_sql(["unplayed", "backlog"])
+# Returns: "(playtime_seconds = 0) AND (tags LIKE '%backlog%')"
+```
+
+#### 4. Filter Counting (`web/utils/helpers.py`)
+
+**Function:** `get_query_filter_counts(cursor, stores, genres, exclude_query) -> dict[str, int]`
+
+Calculates result counts for all filters in a single optimized query.
+
+**Performance:**
+- Single SQL query using `COUNT(CASE WHEN ... THEN 1 END)`
+- Respects current store and genre selections
+- Excludes games matching exclude_query
+- Returns dict mapping filter_id → count
+
+**Usage:**
+```python
+counts = get_query_filter_counts(cursor, ["steam"], ["action"], "hidden = 1")
+# Returns: {"unplayed": 42, "backlog": 15, ...}
+```
+
+#### 5. Route Integration
+
+**Pattern:**
+```python
+# Parse filters from query params
+selected_filters = parse_predefined_filters(request.query_params.get("predefined", ""))
+
+# Build SQL WHERE clause
+filter_sql = build_predefined_filter_sql(selected_filters)
+
+# Add to main query
+if filter_sql:
+    conditions.append(filter_sql)
+```
+
+**Routes Using Filters:**
+- `web/routes/library.py`: Main library page with filter counting
+- `web/routes/collections.py`: Collection detail pages
+- `web/routes/discover.py`: Game discovery page
+
+#### 6. Frontend Components
+
+**Filter Bar (`web/templates/_filter_bar.html`):**
+- Reusable Jinja2 template included in multiple pages
+- Organizes filters by category with collapsible sections
+- Shows result count badges (when available)
+- Maintains filter state via query parameters
+
+**JavaScript (`web/static/js/filters.js`):**
+- Manages dropdown interactions
+- Handles keyboard navigation (Esc, Arrow keys, Enter/Space)
+- Updates ARIA states for accessibility
+- Syncs selections with URL query parameters
+
+**CSS (`web/static/css/filters.css`):**
+- Styles filter dropdowns and badges
+- Provides visual feedback for active filters
+- Responsive design for mobile and desktop
+
+## Data Flow
+
+### User Interaction Flow
+
+```
+User clicks filter checkbox
+  ↓
+JavaScript updates URL with ?predefined=filter-id
+  ↓
+Browser navigates to new URL
+  ↓
+Backend parses predefined query param
+  ↓
+Converts to SQL WHERE conditions
+  ↓
+Executes database query with filters
+  ↓
+Returns filtered game results
+  ↓
+Template renders games with active filter indicators
+```
+
+### Filter Count Flow
+
+```
+Library route handler
+  ↓
+Checks if games exist in result
+  ↓
+Calls get_query_filter_counts() with current context
+  ↓
+Single SQL query counts matches for all filters
+  ↓
+Returns counts dict to template
+  ↓
+Template displays badges next to filter labels
+```
+
+## State Management
+
+### URL-Based State
+
+Filters are stored in URL query parameters for:
+- **Shareability**: Users can bookmark filtered views
+- **Browser history**: Back/forward buttons work naturally
+- **Server-side rendering**: No client-side state sync needed
+
+**Query Parameter Format:**
+```
+?predefined=filter1,filter2&stores=steam,gog&genres=action
+```
+
+### Multi-Page Consistency
+
+The filter bar component is reused across pages:
+- Library (`index.html`)
+- Collections (`collection_detail.html`)
+- Discovery (`discover.html`)
+
+Each page maintains its own filter context but shares the same UI and logic.
+
+## Performance Optimizations
+
+### 1. Database Indexes
+
+Indexes are created on commonly filtered columns:
+- `completed_date`
+- `last_played_date`
+- `release_date`
+- `playtime_seconds`
+- `tags`
+
+**Setup:** `ensure_predefined_query_indexes()` in `web/main.py` creates indexes on startup.
+
+### 2. Efficient Counting
+
+- Single query with `COUNT(CASE)` instead of 18 separate queries
+- Only calculated on library page (most used)
+- Skipped on discover/collection pages to reduce overhead
+
+### 3. SQL Optimization
+
+- All filter conditions use indexed columns
+- `LIKE` clauses use prefix matching where possible
+- NULL checks use `IS NULL` instead of `= NULL`
+
+## Accessibility
+
+### ARIA Attributes
+
+- `aria-label`: Descriptive labels for screen readers
+- `aria-haspopup="true"`: Indicates dropdown menus
+- `aria-expanded`: Dynamic state for open/closed dropdowns
+- `role="group"`: Semantic grouping of related filters
+
+### Keyboard Navigation
+
+- **Esc**: Close all dropdowns
+- **Arrow Up/Down**: Navigate between filters
+- **Enter/Space**: Toggle filter selection
+- **Tab**: Move between interactive elements
+
+### Color Contrast
+
+All filter UI elements meet WCAG 2.1 Level AA contrast requirements.
+
+## Testing
+
+### Unit Tests (`tests/test_predefined_filters.py`)
+
+**Coverage:**
+- Filter parsing with various input formats
+- SQL generation with single/multiple filters
+- Invalid filter handling
+- Edge cases (empty input, unknown IDs)
+
+**26 unit tests** validate core filter logic.
+
+### Integration Tests (`tests/test_predefined_filters_integration.py`)
+
+**Coverage:**
+- HTTP requests with filter query parameters
+- Combinations of filters, stores, and genres
+- NULL value handling
+- Result correctness for each filter
+
+**26 integration tests** validate end-to-end functionality.
+
+## Extension Guide
+
+### Adding a New Filter
+
+1. **Define in `PREDEFINED_QUERIES`:**
+```python
+"new-filter": {
+    "label": "Display Name",
+    "description": "What this filter does",
+    "query": "SQL WHERE condition",
+    "category": "existing_category"
+}
+```
+
+2. **Create database index (if needed):**
+```python
+cursor.execute("""
+    CREATE INDEX IF NOT EXISTS idx_new_column
+    ON games(new_column)
+""")
+```
+
+3. **Add to filter bar template:**
+
+Template will automatically pick up new filter from `PREDEFINED_QUERIES`.
+
+4. **Write tests:**
+```python
+def test_new_filter_integration(client):
+    response = client.get("/library?predefined=new-filter")
+    # Verify results match expected SQL condition
+```
+
+### Adding a New Category
+
+1. **Update `PREDEFINED_QUERIES`:**
+
+Add filters with `"category": "new_category"`
+
+2. **Update filter bar template:**
+
+Add new section in `_filter_bar.html`:
+```html
+<div class="filter-section">
+    <button class="filter-dropdown-toggle" aria-label="Category Name">
+        Category Name
+    </button>
+    <div class="filter-options" role="group">
+        {% for filter_id, filter_data in predefined_queries.items() %}
+            {% if filter_data.category == 'new_category' %}
+                <!-- Filter checkbox -->
+            {% endif %}
+        {% endfor %}
+    </div>
+</div>
+```
+
+3. **Update JavaScript (if interactive):**
+
+Add dropdown toggle handler in `filters.js`.
+
+## Maintenance Notes
+
+### Common Issues
+
+**Issue:** Filter returns no results unexpectedly
+- **Check:** NULL handling in SQL condition
+- **Fix:** Use `IS NULL` or `COALESCE()` for nullable columns
+
+**Issue:** Filter counts are incorrect
+- **Check:** `get_query_filter_counts()` includes all context (stores, genres, exclude_query)
+- **Fix:** Ensure count query matches main query conditions
+
+**Issue:** Filter not appearing in UI
+- **Check:** Filter is in `PREDEFINED_QUERIES` with valid category
+- **Check:** Template includes filter bar component
+- **Fix:** Verify filter_id matches between backend and template

+# predefined-query-filters Specification
+
+## Purpose
+TBD - created by archiving change add-predefined-queries. Update Purpose after archive.
+## Requirements
+### Requirement: Predefined filter definitions
+The system SHALL provide 18 predefined query filters organized into 4 categories (Gameplay, Ratings, Dates, Content). Each filter SHALL map to a specific SQL WHERE clause condition that filters games based on existing database fields.
+
+#### Scenario: Filter definitions are available
+- **WHEN** the library route initializes
+- **THEN** all 18 predefined filters SHALL be defined with their SQL conditions and display names
+
+#### Scenario: Filters are organized by category
+- **WHEN** filters are rendered in the UI
+- **THEN** filters SHALL be grouped into 4 categories: Gameplay (5 filters), Ratings (7 filters), Dates (5 filters), and Content (2 filters)
+
+### Requirement: Query parameter handling
+The system SHALL accept a `queries` parameter in the library route that contains a list of filter IDs. The route SHALL validate filter IDs against the predefined filter definitions.
+
+#### Scenario: Single filter parameter
+- **WHEN** user navigates to `/library?queries=unplayed`
+- **THEN** system SHALL apply the "Unplayed" filter condition to the games query
+
+#### Scenario: Multiple filter parameters
+- **WHEN** user navigates to `/library?queries=unplayed&queries=highly-rated`
+- **THEN** system SHALL apply both filter conditions using AND logic
+
+#### Scenario: Invalid filter ID
+- **WHEN** user provides an invalid filter ID in the queries parameter
+- **THEN** system SHALL ignore the invalid filter ID and continue processing valid filters
+
+#### Scenario: Empty queries parameter
+- **WHEN** queries parameter is empty or not provided
+- **THEN** system SHALL apply no predefined filters and show all games based on other filters
+
+### Requirement: SQL filter application
+The system SHALL build SQL WHERE clauses by combining predefined filter conditions with existing filters (stores, genres, search). All filters SHALL be combined using AND logic.
+
+#### Scenario: Filter with existing store filter
+- **WHEN** user applies queries=unplayed with stores=steam
+- **THEN** system SHALL return only Steam games that are unplayed
+
+#### Scenario: Filter with existing genre filter
+- **WHEN** user applies queries=highly-rated with genres=Action
+- **THEN** system SHALL return only Action games with rating >= 90
+
+#### Scenario: Multiple predefined filters combined
+- **WHEN** user applies queries=unplayed&queries=well-rated
+- **THEN** system SHALL return games where (playtime_hours IS NULL OR playtime_hours = 0) AND total_rating >= 75
+
+#### Scenario: Filter handles NULL values gracefully
+- **WHEN** a filter condition references a field with NULL values
+- **THEN** system SHALL handle NULL values according to SQL logic (e.g., "IS NULL" for Unrated filter)
+
+### Requirement: Filter UI display
+The system SHALL display predefined query filters in a dedicated filter section on the library page. Filters SHALL be organized by category with category headers.
+
+#### Scenario: Filter section is visible
+- **WHEN** user views the library page

+
+#### Scenario: Filter tags are clickable
+- **WHEN** user views filter tags
+- **THEN** each filter SHALL be displayed as a clickable tag pill with the filter display name
+
+#### Scenario: Active filters are highlighted
+- **WHEN** a filter is active (present in URL queries parameter)
+- **THEN** the filter tag SHALL have visual highlighting (active state)
+
+#### Scenario: Filter categories have headers
+- **WHEN** filters are displayed
+- **THEN** each category SHALL have a visible header (e.g., "Gameplay:", "Ratings:")
+
+### Requirement: Filter toggle behavior
+The system SHALL allow users to toggle predefined filters on and off by clicking filter tags. Toggling a filter SHALL update the URL queries parameter and reload the filtered game list.
+
+#### Scenario: Activate filter
+- **WHEN** user clicks an inactive filter tag
+- **THEN** system SHALL add the filter ID to the queries parameter and reload the page with filtered results
+
+#### Scenario: Deactivate filter
+- **WHEN** user clicks an active filter tag
+- **THEN** system SHALL remove the filter ID from the queries parameter and reload the page
+
+#### Scenario: Toggle preserves other filters
+- **WHEN** user toggles a predefined filter while store or genre filters are active
+- **THEN** system SHALL preserve all other active filters in the URL
+
+#### Scenario: Multiple filters can be active
+- **WHEN** user activates multiple predefined filters
+- **THEN** system SHALL allow any combination of filters to be active simultaneously
+
+### Requirement: URL persistence
+The system SHALL persist active predefined filters in the URL using repeated `queries` parameters. URLs with active filters SHALL be bookmarkable and shareable.
+
+#### Scenario: Bookmarked URL restores filters
+- **WHEN** user bookmarks `/library?queries=unplayed&queries=highly-rated`
+- **THEN** navigating to that URL SHALL apply both filters automatically
+
+#### Scenario: Shared URL applies same filters
+- **WHEN** user shares a library URL with queries parameters
+- **THEN** other users opening that URL SHALL see the same filtered view

-description: Implement tasks from an OpenSpec change (Experimental)
----
-
-Implement tasks from an OpenSpec change.
-
-**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **Select the change**
-
-   If a name is provided, use it. Otherwise:
-   - Infer from conversation context if the user mentioned a change
-   - Auto-select if only one active change exists
-   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
-
-   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
-
-3. **Get apply instructions**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns:
-   - Context file paths (varies by schema)
-   - Progress (total, complete, remaining)
-   - Task list with status
-   - Dynamic instruction based on current state
-
-   **Handle states:**
-   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
-   - If `state: "all_done"`: congratulate, suggest archive
-   - Otherwise: proceed to implementation
-
-4. **Read context files**
-
-   Read the files listed in `contextFiles` from the apply instructions output.
-   The files depend on the schema being used:
-   - **spec-driven**: proposal, specs, design, tasks
-   - Other schemas: follow the contextFiles from CLI output
-
-5. **Show current progress**
-
-   Display:
-   - Schema being used
-   - Progress: "N/M tasks complete"
-   - Remaining tasks overview
-   - Dynamic instruction from CLI
-
-6. **Implement tasks (loop until done or blocked)**
-
-   For each pending task:
-   - Show which task is being worked on
-   - Make the code changes required
-   - Keep changes minimal and focused
-   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
-   - Continue to next task
-
-   **Pause if:**
-   - Task is unclear → ask for clarification
-   - Implementation reveals a design issue → suggest updating artifacts
-   - Error or blocker encountered → report and wait for guidance
-   - User interrupts
-
-7. **On completion or pause, show status**
-
-   Display:
-   - Tasks completed this session
-   - Overall progress: "N/M tasks complete"
-   - If all done: suggest archive
-   - If paused: explain why and wait for guidance
-
-**Output During Implementation**
-
-```
-## Implementing: <change-name> (schema: <schema-name>)
-
-Working on task 3/7: <task description>
-[...implementation happening...]
-✓ Task complete
-
-Working on task 4/7: <task description>
-[...implementation happening...]
-✓ Task complete
-```
-
-**Output On Completion**
-
-```
-## Implementation Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 7/7 tasks complete ✓
-
-### Completed This Session
-- [x] Task 1
-- [x] Task 2
-...
-
-All tasks complete! You can archive this change with `/opsx:archive`.
-```
-
-**Output On Pause (Issue Encountered)**
-
-```
-## Implementation Paused
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 4/7 tasks complete
-
-### Issue Encountered
-<description of the issue>
-
-**Options:**
-1. <option 1>
-2. <option 2>
-3. Other approach
-
-What would you like to do?
-```
-
-**Guardrails**
-- Keep going through tasks until done or blocked
-- Always read context files before starting (from the apply instructions output)
-- If task is ambiguous, pause and ask before implementing
-- If implementation reveals issues, pause and suggest artifact updates
-- Keep code changes minimal and scoped to each task
-- Update task checkbox immediately after completing each task
-- Pause on errors, blockers, or unclear requirements - don't guess
-- Use contextFiles from CLI output, don't assume specific file names
-
-**Fluid Workflow Integration**
-
-This skill supports the "actions on a change" model:
-
-- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
-- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

-description: Archive a completed change in the experimental workflow
----
-
-Archive a completed change in the experimental workflow.
-
-**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show only active changes (not already archived).
-   Include the schema used for each change if available.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check artifact completion status**
-
-   Run `openspec status --change "<name>" --json` to check artifact completion.
-
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used
-   - `artifacts`: List of artifacts with their status (`done` or other)
-
-   **If any artifacts are not `done`:**
-   - Display warning listing incomplete artifacts
-   - Prompt user for confirmation to continue
-   - Proceed if user confirms
-
-3. **Check task completion status**
-
-   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
-
-   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
-
-   **If incomplete tasks found:**
-   - Display warning showing count of incomplete tasks
-   - Prompt user for confirmation to continue
-   - Proceed if user confirms
-
-   **If no tasks file exists:** Proceed without task-related warning.
-
-4. **Assess delta spec sync state**
-
-   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
-
-   **If delta specs exist:**
-   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
-   - Determine what changes would be applied (adds, modifications, removals, renames)
-   - Show a combined summary before prompting
-
-   **Prompt options:**
-   - If changes needed: "Sync now (recommended)", "Archive without syncing"
-   - If already synced: "Archive now", "Sync anyway", "Cancel"
-
-   If user chooses sync, execute `/opsx:sync` logic. Proceed to archive regardless of choice.
-
-5. **Perform the archive**
-
-   Create the archive directory if it doesn't exist:
-   ```bash
-   mkdir -p openspec/changes/archive
-   ```
-
-   Generate target name using current date: `YYYY-MM-DD-<change-name>`
-
-   **Check if target already exists:**
-   - If yes: Fail with error, suggest renaming existing archive or using different date
-   - If no: Move the change directory to archive
-
-   ```bash
-   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
-   ```
-
-6. **Display summary**
-
-   Show archive completion summary including:
-   - Change name
-   - Schema that was used
-   - Archive location
-   - Spec sync status (synced / sync skipped / no delta specs)
-   - Note about any warnings (incomplete artifacts/tasks)
-
-**Output On Success**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
-**Specs:** ✓ Synced to main specs
-
-All artifacts complete. All tasks complete.
-```
-
-**Output On Success (No Delta Specs)**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
-**Specs:** No delta specs
-
-All artifacts complete. All tasks complete.
-```
-
-**Output On Success With Warnings**
-
-```
-## Archive Complete (with warnings)
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
-**Specs:** Sync skipped (user chose to skip)
-
-**Warnings:**
-- Archived with 2 incomplete artifacts
-- Archived with 3 incomplete tasks
-- Delta spec sync was skipped (user chose to skip)
-
-Review the archive if this was not intentional.
-```
-
-**Output On Error (Archive Exists)**
-
-```
-## Archive Failed
-
-**Change:** <change-name>
-**Target:** openspec/changes/archive/YYYY-MM-DD-<name>/
-
-Target archive directory already exists.
-
-**Options:**
-1. Rename the existing archive
-2. Delete the existing archive if it's a duplicate
-3. Wait until a different date to archive
-```
-
-**Guardrails**
-- Always prompt for change selection if not provided
-- Use artifact graph (openspec status --json) for completion checking
-- Don't block archive on warnings - just inform and confirm
-- Preserve .openspec.yaml when moving to archive (it moves with the directory)
-- Show clear summary of what happened
-- If sync is requested, use /opsx:sync approach (agent-driven)
-- If delta specs exist, always run the sync assessment and show the combined summary before prompting

-description: Archive multiple completed changes at once
----
-
-Archive multiple completed changes in a single operation.
-
-This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.
-
-**Input**: None required (prompts for selection)
-
-**Steps**
-
-1. **Get active changes**
-
-   Run `openspec list --json` to get all active changes.
-
-   If no active changes exist, inform user and stop.
-
-2. **Prompt for change selection**
-
-   Use **AskUserQuestion tool** with multi-select to let user choose changes:
-   - Show each change with its schema
-   - Include an option for "All changes"
-   - Allow any number of selections (1+ works, 2+ is the typical use case)
-
-   **IMPORTANT**: Do NOT auto-select. Always let the user choose.
-
-3. **Batch validation - gather status for all selected changes**
-
-   For each selected change, collect:
-
-   a. **Artifact status** - Run `openspec status --change "<name>" --json`
-      - Parse `schemaName` and `artifacts` list
-      - Note which artifacts are `done` vs other states
-
-   b. **Task completion** - Read `openspec/changes/<name>/tasks.md`
-      - Count `- [ ]` (incomplete) vs `- [x]` (complete)
-      - If no tasks file exists, note as "No tasks"
-
-   c. **Delta specs** - Check `openspec/changes/<name>/specs/` directory
-      - List which capability specs exist
-      - For each, extract requirement names (lines matching `### Requirement: <name>`)
-
-4. **Detect spec conflicts**
-
-   Build a map of `capability -> [changes that touch it]`:
-
-   ```
-   auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
-   api  -> [change-c]            <- OK (only 1 change)
-   ```
-
-   A conflict exists when 2+ selected changes have delta specs for the same capability.
-
-5. **Resolve conflicts agentically**
-
-   **For each conflict**, investigate the codebase:
-
-   a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
-
-   b. **Search the codebase** for implementation evidence:
-      - Look for code implementing requirements from each delta spec
-      - Check for related files, functions, or tests
-
-   c. **Determine resolution**:
-      - If only one change is actually implemented -> sync that one's specs
-      - If both implemented -> apply in chronological order (older first, newer overwrites)
-      - If neither implemented -> skip spec sync, warn user
-
-   d. **Record resolution** for each conflict:
-      - Which change's specs to apply
-      - In what order (if both)
-      - Rationale (what was found in codebase)
-
-6. **Show consolidated status table**
-
-   Display a table summarizing all changes:
-
-   ```
-   | Change               | Artifacts | Tasks | Specs   | Conflicts | Status |
-   |---------------------|-----------|-------|---------|-----------|--------|
-   | schema-management   | Done      | 5/5   | 2 delta | None      | Ready  |
-   | project-config      | Done      | 3/3   | 1 delta | None      | Ready  |
-   | add-oauth           | Done      | 4/4   | 1 delta | auth (!)  | Ready* |
-   | add-verify-skill    | 1 left    | 2/5   | None    | None      | Warn   |
-   ```
-
-   For conflicts, show the resolution:
-   ```
-   * Conflict resolution:
-     - auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
-   ```
-
-   For incomplete changes, show warnings:
-   ```
-   Warnings:
-   - add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
-   ```
-
-7. **Confirm batch operation**
-
-   Use **AskUserQuestion tool** with a single confirmation:
-
-   - "Archive N changes?" with options based on status
-   - Options might include:
-     - "Archive all N changes"
-     - "Archive only N ready changes (skip incomplete)"
-     - "Cancel"
-
-   If there are incomplete changes, make clear they'll be archived with warnings.
-
-8. **Execute archive for each confirmed change**
-
-   Process changes in the determined order (respecting conflict resolution):
-
-   a. **Sync specs** if delta specs exist:
-      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
-      - For conflicts, apply in resolved order
-      - Track if sync was done
-
-   b. **Perform the archive**:
-      ```bash
-      mkdir -p openspec/changes/archive
-      mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
-      ```
-
-   c. **Track outcome** for each change:
-      - Success: archived successfully
-      - Failed: error during archive (record error)
-      - Skipped: user chose not to archive (if applicable)
-
-9. **Display summary**
-
-   Show final results:
-
-   ```
-   ## Bulk Archive Complete
-
-   Archived 3 changes:
-   - schema-management-cli -> archive/2026-01-19-schema-management-cli/
-   - project-config -> archive/2026-01-19-project-config/
-   - add-oauth -> archive/2026-01-19-add-oauth/
-
-   Skipped 1 change:
-   - add-verify-skill (user chose not to archive incomplete)
-
-   Spec sync summary:
-   - 4 delta specs synced to main specs
-   - 1 conflict resolved (auth: applied both in chronological order)
-   ```
-
-   If any failures:
-   ```
-   Failed 1 change:
-   - some-change: Archive directory already exists
-   ```
-
-**Conflict Resolution Examples**
-
-Example 1: Only one implemented
-```
-Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
-
-Checking add-oauth:
-- Delta adds "OAuth Provider Integration" requirement
-- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
-
-Checking add-jwt:
-- Delta adds "JWT Token Handling" requirement
-- Searching codebase... no JWT implementation found
-
-Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
-```
-
-Example 2: Both implemented
-```
-Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
-
-Checking add-rest-api (created 2026-01-10):
-- Delta adds "REST Endpoints" requirement
-- Searching codebase... found src/api/rest.ts
-
-Checking add-graphql (created 2026-01-15):
-- Delta adds "GraphQL Schema" requirement
-- Searching codebase... found src/api/graphql.ts
-
-Resolution: Both implemented. Will apply add-rest-api specs first,
-then add-graphql specs (chronological order, newer takes precedence).

-**Guardrails**
-- Allow any number of changes (1+ is fine, 2+ is the typical use case)
-- Always prompt for selection, never auto-select
-- Detect spec conflicts early and resolve by checking codebase
-- When both changes are implemented, apply specs in chronological order
-- Skip spec sync only when implementation is missing (warn user)
-- Show clear per-change status before confirming
-- Use single confirmation for entire batch
-- Track and report all outcomes (success/skip/fail)
-- Preserve .openspec.yaml when moving to archive
-- Archive directory target uses current date: YYYY-MM-DD-<name>
-- If archive target exists, fail that change but continue with others

-description: Continue working on a change - create the next artifact (Experimental)
----
-
-Continue working on a change by creating the next artifact.
-
-**Input**: Optionally specify a change name after `/opsx:continue` (e.g., `/opsx:continue add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes sorted by most recently modified. Then use the **AskUserQuestion tool** to let the user select which change to work on.
-
-   Present the top 3-4 most recently modified changes as options, showing:
-   - Change name
-   - Schema (from `schema` field if present, otherwise "spec-driven")
-   - Status (e.g., "0/5 tasks", "complete", "no tasks")
-   - How recently it was modified (from `lastModified` field)
-
-   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check current status**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand current state. The response includes:
-   - `schemaName`: The workflow schema being used (e.g., "spec-driven")
-   - `artifacts`: Array of artifacts with their status ("done", "ready", "blocked")
-   - `isComplete`: Boolean indicating if all artifacts are complete
-
-3. **Act based on status**:
-
-   ---
-
-   **If all artifacts are complete (`isComplete: true`)**:
-   - Congratulate the user
-   - Show final status including the schema used
-   - Suggest: "All artifacts created! You can now implement this change with `/opsx:apply` or archive it with `/opsx:archive`."
-   - STOP
-
-   ---
-
-   **If artifacts are ready to create** (status shows artifacts with `status: "ready"`):
-   - Pick the FIRST artifact with `status: "ready"` from the status output
-   - Get its instructions:
-     ```bash
-     openspec instructions <artifact-id> --change "<name>" --json
-     ```
-   - Parse the JSON. The key fields are:
-     - `context`: Project background (constraints for you - do NOT include in output)
-     - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-     - `template`: The structure to use for your output file
-     - `instruction`: Schema-specific guidance
-     - `outputPath`: Where to write the artifact
-     - `dependencies`: Completed artifacts to read for context
-   - **Create the artifact file**:
-     - Read any completed dependency files for context
-     - Use `template` as the structure - fill in its sections
-     - Apply `context` and `rules` as constraints when writing - but do NOT copy them into the file
-     - Write to the output path specified in instructions
-   - Show what was created and what's now unlocked
-   - STOP after creating ONE artifact
-
-   ---
-
-   **If no artifacts are ready (all blocked)**:
-   - This shouldn't happen with a valid schema
-   - Show status and suggest checking for issues
-
-4. **After creating an artifact, show progress**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After each invocation, show:
-- Which artifact was created
-- Schema workflow being used
-- Current progress (N/M complete)
-- What artifacts are now unlocked
-- Prompt: "Run `/opsx:continue` to create the next artifact"
-
-**Artifact Creation Guidelines**
-
-The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
-
-Common artifact patterns:
-
-**spec-driven schema** (proposal → specs → design → tasks):
-- **proposal.md**: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
-  - The Capabilities section is critical - each capability listed will need a spec file.
-- **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
-- **design.md**: Document technical decisions, architecture, and implementation approach.
-- **tasks.md**: Break down implementation into checkboxed tasks.
-
-For other schemas, follow the `instruction` field from the CLI output.
-
-**Guardrails**
-- Create ONE artifact per invocation
-- Always read dependency artifacts before creating a new one
-- Never skip artifacts or create out of order
-- If context is unclear, ask the user before creating
-- Verify the artifact file exists after writing before marking progress
-- Use the schema's artifact sequence, don't assume specific artifact names
-- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
-  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
-  - These guide what you write, but should never appear in the output

-description: Enter explore mode - think through ideas, investigate problems, clarify requirements
----
-
-Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
-
-**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first (e.g., start a change with `/opsx:new` or `/opsx:ff`). You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
-
-**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
-
-**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
-- A vague idea: "real-time collaboration"
-- A specific problem: "the auth system is getting unwieldy"
-- A change name: "add-dark-mode" (to explore in context of that change)
-- A comparison: "postgres vs sqlite for this"
-- Nothing (just enter explore mode)
-
----
-
-## The Stance
-
-- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
-- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
-- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
-- **Adaptive** - Follow interesting threads, pivot when new information emerges
-- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
-- **Grounded** - Explore the actual codebase when relevant, don't just theorize
-
----
-
-## What You Might Do
-
-Depending on what the user brings, you might:
-
-**Explore the problem space**
-- Ask clarifying questions that emerge from what they said
-- Challenge assumptions
-- Reframe the problem
-- Find analogies
-
-**Investigate the codebase**
-- Map existing architecture relevant to the discussion
-- Find integration points
-- Identify patterns already in use
-- Surface hidden complexity
-
-**Compare options**
-- Brainstorm multiple approaches
-- Build comparison tables
-- Sketch tradeoffs
-- Recommend a path (if asked)
-
-**Visualize**

----
-
-## OpenSpec Awareness
-
-You have full context of the OpenSpec system. Use it naturally, don't force it.
-
-### Check for context
-
-At the start, quickly check what exists:
-```bash
-openspec list --json
-```
-
-This tells you:
-- If there are active changes
-- Their names, schemas, and status
-- What the user might be working on
-
-If the user mentioned a specific change name, read its artifacts for context.
-
-### When no change exists
-
-Think freely. When insights crystallize, you might offer:
-
-- "This feels solid enough to start a change. Want me to create one?"
-  → Can transition to `/opsx:new` or `/opsx:ff`
-- Or keep exploring - no pressure to formalize
-
-### When a change exists
-
-If the user mentions a change or you detect one is relevant:
-
-1. **Read existing artifacts for context**
-   - `openspec/changes/<name>/proposal.md`
-   - `openspec/changes/<name>/design.md`
-   - `openspec/changes/<name>/tasks.md`
-   - etc.
-
-2. **Reference them naturally in conversation**
-   - "Your design mentions using Redis, but we just realized SQLite fits better..."
-   - "The proposal scopes this to premium users, but we're now thinking everyone..."
-
-3. **Offer to capture when decisions are made**
-
-   | Insight Type | Where to Capture |
-   |--------------|------------------|
-   | New requirement discovered | `specs/<capability>/spec.md` |
-   | Requirement changed | `specs/<capability>/spec.md` |
-   | Design decision made | `design.md` |
-   | Scope changed | `proposal.md` |
-   | New work identified | `tasks.md` |
-   | Assumption invalidated | Relevant artifact |
-
-   Example offers:
-   - "That's a design decision. Capture it in design.md?"
-   - "This is a new requirement. Add it to specs?"
-   - "This changes scope. Update the proposal?"
-
-4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
-
----
-
-## What You Don't Have To Do
-
-- Follow a script
-- Ask the same questions every time
-- Produce a specific artifact
-- Reach a conclusion
-- Stay on topic if a tangent is valuable
-- Be brief (this is thinking time)
-
----
-
-## Ending Discovery
-
-There's no required ending. Discovery might:
-
-- **Flow into action**: "Ready to start? `/opsx:new` or `/opsx:ff`"
-- **Result in artifact updates**: "Updated design.md with these decisions"
-- **Just provide clarity**: User has what they need, moves on
-- **Continue later**: "We can pick this up anytime"
-
-When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
-
----
-
-## Guardrails
-
-- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
-- **Don't fake understanding** - If something is unclear, dig deeper
-- **Don't rush** - Discovery is thinking time, not task time
-- **Don't force structure** - Let patterns emerge naturally
-- **Don't auto-capture** - Offer to save insights, don't just do it
-- **Do visualize** - A good diagram is worth many paragraphs
-- **Do explore the codebase** - Ground discussions in reality
-- **Do question assumptions** - Including the user's and your own

-description: Create a change and generate all artifacts needed for implementation in one go
----
-
-Fast-forward through artifact creation - generate everything needed to start implementation.
-
-**Input**: The argument after `/opsx:ff` is the change name (kebab-case), OR a description of what the user wants to build.
-
-**Steps**
-
-1. **If no input provided, ask what they want to build**
-
-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."
-
-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   This creates a scaffolded change at `openspec/changes/<name>/`.
-
-3. **Get the artifact build order**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to get:
-   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
-   - `artifacts`: list of all artifacts with their status and dependencies
-
-4. **Create artifacts in sequence until apply-ready**
-
-   Use the **TodoWrite tool** to track progress through the artifacts.
-
-   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
-
-   a. **For each artifact that is `ready` (dependencies satisfied)**:
-      - Get instructions:
-        ```bash
-        openspec instructions <artifact-id> --change "<name>" --json
-        ```
-      - The instructions JSON includes:
-        - `context`: Project background (constraints for you - do NOT include in output)
-        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-        - `template`: The structure to use for your output file
-        - `instruction`: Schema-specific guidance for this artifact type
-        - `outputPath`: Where to write the artifact
-        - `dependencies`: Completed artifacts to read for context
-      - Read any completed dependency files for context
-      - Create the artifact file using `template` as the structure
-      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
-      - Show brief progress: "✓ Created <artifact-id>"
-
-   b. **Continue until all `applyRequires` artifacts are complete**
-      - After creating each artifact, re-run `openspec status --change "<name>" --json`
-      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
-      - Stop when all `applyRequires` artifacts are done
-
-   c. **If an artifact requires user input** (unclear context):
-      - Use **AskUserQuestion tool** to clarify
-      - Then continue with creation
-
-5. **Show final status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After completing all artifacts, summarize:
-- Change name and location
-- List of artifacts created with brief descriptions
-- What's ready: "All artifacts created! Ready for implementation."
-- Prompt: "Run `/opsx:apply` to start implementing."
-
-**Artifact Creation Guidelines**
-
-- Follow the `instruction` field from `openspec instructions` for each artifact type
-- The schema defines what each artifact should contain - follow it
-- Read dependency artifacts for context before creating new ones
-- Use the `template` as a starting point, filling in based on context
-
-**Guardrails**
-- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
-- Always read dependency artifacts before creating a new one
-- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
-- If a change with that name already exists, ask if user wants to continue it or create a new one
-- Verify each artifact file exists after writing before proceeding to next

-description: Start a new change using the experimental artifact workflow (OPSX)
----
-
-Start a new change using the experimental artifact-driven approach.
-
-**Input**: The argument after `/opsx:new` is the change name (kebab-case), OR a description of what the user wants to build.
-
-**Steps**
-
-1. **If no input provided, ask what they want to build**
-
-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."
-
-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Determine the workflow schema**
-
-   Use the default schema (omit `--schema`) unless the user explicitly requests a different workflow.
-
-   **Use a different schema only if the user mentions:**
-   - A specific schema name → use `--schema <name>`
-   - "show workflows" or "what workflows" → run `openspec schemas --json` and let them choose
-
-   **Otherwise**: Omit `--schema` to use the default.
-
-3. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   Add `--schema <name>` only if the user requested a specific workflow.
-   This creates a scaffolded change at `openspec/changes/<name>/` with the selected schema.
-
-4. **Show the artifact status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-   This shows which artifacts need to be created and which are ready (dependencies satisfied).
-
-5. **Get instructions for the first artifact**
-   The first artifact depends on the schema. Check the status output to find the first artifact with status "ready".
-   ```bash
-   openspec instructions <first-artifact-id> --change "<name>"
-   ```
-   This outputs the template and context for creating the first artifact.
-
-6. **STOP and wait for user direction**
-
-**Output**
-
-After completing the steps, summarize:
-- Change name and location
-- Schema/workflow being used and its artifact sequence
-- Current status (0/N artifacts complete)
-- The template for the first artifact
-- Prompt: "Ready to create the first artifact? Run `/opsx:continue` or just describe what this change is about and I'll draft it."
-
-**Guardrails**
-- Do NOT create any artifacts yet - just show the instructions
-- Do NOT advance beyond showing the first artifact template
-- If the name is invalid (not kebab-case), ask for a valid name
-- If a change with that name already exists, suggest using `/opsx:continue` instead
-- Pass --schema if using a non-default workflow

-description: Guided onboarding - walk through a complete OpenSpec workflow cycle with narration
----
-
-Guide the user through their first complete OpenSpec workflow cycle. This is a teaching experience—you'll do real work in their codebase while explaining each step.
-
----
-
-## Preflight
-
-Before starting, check if OpenSpec is initialized:
-
-```bash
-openspec status --json 2>&1 || echo "NOT_INITIALIZED"
-```
-
-**If not initialized:**
-> OpenSpec isn't set up in this project yet. Run `openspec init` first, then come back to `/opsx:onboard`.
-
-Stop here if not initialized.
-
----
-
-## Phase 1: Welcome
-
-Display:
-
-```
-## Welcome to OpenSpec!
-
-I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
-
-**What we'll do:**
-1. Pick a small, real task in your codebase
-2. Explore the problem briefly
-3. Create a change (the container for our work)
-4. Build the artifacts: proposal → specs → design → tasks
-5. Implement the tasks
-6. Archive the completed change
-
-**Time:** ~15-20 minutes
-
-Let's start by finding something to work on.
-```
-
----
-
-## Phase 2: Task Selection
-
-### Codebase Analysis
-
-Scan the codebase for small improvement opportunities. Look for:
-
-1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
-2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
-3. **Functions without tests** - Cross-reference `src/` with test directories
-4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
-5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
-6. **Missing validation** - User input handlers without validation
-
-Also check recent git activity:
-```bash
-git log --oneline -10 2>/dev/null || echo "No git history"
-```
-
-### Present Suggestions
-
-From your analysis, present 3-4 specific suggestions:
-
-```
-## Task Suggestions
-
-Based on scanning your codebase, here are some good starter tasks:
-
-**1. [Most promising task]**
-   Location: `src/path/to/file.ts:42`
-   Scope: ~1-2 files, ~20-30 lines
-   Why it's good: [brief reason]
-
-**2. [Second task]**
-   Location: `src/another/file.ts`
-   Scope: ~1 file, ~15 lines
-   Why it's good: [brief reason]
-
-**3. [Third task]**
-   Location: [location]
-   Scope: [estimate]
-   Why it's good: [brief reason]
-
-**4. Something else?**
-   Tell me what you'd like to work on.
-
-Which task interests you? (Pick a number or describe your own)
-```
-
-**If nothing found:** Fall back to asking what the user wants to build:
-> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
-
-### Scope Guardrail
-
-If the user picks or describes something too large (major feature, multi-day work):
-
-```
-That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
-
-For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
-
-**Options:**
-1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
-2. **Pick something else** - One of the other suggestions, or a different small task?
-3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
-
-What would you prefer?
-```
-
-Let the user override if they insist—this is a soft guardrail.
-
----
-
-## Phase 3: Explore Demo
-
-Once a task is selected, briefly demonstrate explore mode:
-
-```
-Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
-```
-
-Spend 1-2 minutes investigating the relevant code:
-- Read the file(s) involved
-- Draw a quick ASCII diagram if it helps
-- Note any considerations
-
-```
-## Quick Exploration
-
-[Your brief analysis—what you found, any considerations]
-
-┌─────────────────────────────────────────┐
-│   [Optional: ASCII diagram if helpful]  │
-└─────────────────────────────────────────┘
-
-Explore mode (`/opsx:explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
-
-Now let's create a change to hold our work.
-```
-
-**PAUSE** - Wait for user acknowledgment before proceeding.

-A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives in `openspec/changes/<name>/` and holds your artifacts—proposal, specs, design, tasks.
-
-Let me create one for our task.
-```
-
-**DO:** Create the change with a derived kebab-case name:
-```bash
-openspec new change "<derived-name>"
-```
-
-**SHOW:**
-```
-Created: `openspec/changes/<name>/`
-
-The folder structure:
-```
-openspec/changes/<name>/
-├── proposal.md    ← Why we're doing this (empty, we'll fill it)
-├── design.md      ← How we'll build it (empty)
-├── specs/         ← Detailed requirements (empty)
-└── tasks.md       ← Implementation checklist (empty)
-```
-
-Now let's fill in the first artifact—the proposal.
-```
-
----
-
-## Phase 5: Proposal
-
-**EXPLAIN:**
-```
-## The Proposal
-
-The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
-
-I'll draft one based on our task.
-```
-
-**DO:** Draft the proposal content (don't save yet):
-
-```
-Here's a draft proposal:
-
----
-
-## Why
-
-[1-2 sentences explaining the problem/opportunity]
-
-## What Changes
-
-[Bullet points of what will be different]
-
-## Capabilities
-
-### New Capabilities
-- `<capability-name>`: [brief description]
-
-### Modified Capabilities
-<!-- If modifying existing behavior -->
-
-## Impact
-
-- `src/path/to/file.ts`: [what changes]
-- [other files if applicable]
-
----
-
-Does this capture the intent? I can adjust before we save it.
-```
-
-**PAUSE** - Wait for user approval/feedback.
-
-After approval, save the proposal:
-```bash
-openspec instructions proposal --change "<name>" --json
-```
-Then write the content to `openspec/changes/<name>/proposal.md`.
-
-```
-Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
-
-Next up: specs.
-```
-
----
-
-## Phase 6: Specs
-
-**EXPLAIN:**
-```
-## Specs
-
-Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
-
-For a small task like this, we might only need one spec file.
-```
-
-**DO:** Create the spec file:
-```bash
-mkdir -p openspec/changes/<name>/specs/<capability-name>
-```
-
-Draft the spec content:
-
-```
-Here's the spec:
-
----
-
-## ADDED Requirements
-
-### Requirement: <Name>
-
-<Description of what the system should do>
-
-#### Scenario: <Scenario name>
-
-- **WHEN** <trigger condition>
-- **THEN** <expected outcome>
-- **AND** <additional outcome if needed>
-
----
-
-This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
-```
-
-Save to `openspec/changes/<name>/specs/<capability>/spec.md`.
-
----
-
-## Phase 7: Design
-
-**EXPLAIN:**
-```
-## Design
-
-The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
-
-For small changes, this might be brief. That's fine—not every change needs deep design discussion.
-```
-
-**DO:** Draft design.md:
-
-```
-Here's the design:
-
----
-
-## Context
-
-[Brief context about the current state]
-
-## Goals / Non-Goals
-
-**Goals:**
-- [What we're trying to achieve]
-
-**Non-Goals:**
-- [What's explicitly out of scope]
-
-## Decisions
-
-### Decision 1: [Key decision]
-
-[Explanation of approach and rationale]
-
----
-
-For a small task, this captures the key decisions without over-engineering.
-```
-
-Save to `openspec/changes/<name>/design.md`.
-
----
-
-## Phase 8: Tasks
-
-**EXPLAIN:**
-```
-## Tasks
-
-Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
-
-These should be small, clear, and in logical order.
-```
-
-**DO:** Generate tasks based on specs and design:
-
-```
-Here are the implementation tasks:
-
----
-
-## 1. [Category or file]
-
-- [ ] 1.1 [Specific task]
-- [ ] 1.2 [Specific task]
-
-## 2. Verify
-
-- [ ] 2.1 [Verification step]
-
----
-
-Each checkbox becomes a unit of work in the apply phase. Ready to implement?
-```
-
-**PAUSE** - Wait for user to confirm they're ready to implement.
-
-Save to `openspec/changes/<name>/tasks.md`.
-
----
-
-## Phase 9: Apply (Implementation)
-
-**EXPLAIN:**
-```
-## Implementation
-
-Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
-```
-
-**DO:** For each task:
-
-1. Announce: "Working on task N: [description]"
-2. Implement the change in the codebase
-3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
-4. Mark complete in tasks.md: `- [ ]` → `- [x]`
-5. Brief status: "✓ Task N complete"
-
-Keep narration light—don't over-explain every line of code.
-
-After all tasks:
-
-```
-## Implementation Complete
-
-All tasks done:
-- [x] Task 1
-- [x] Task 2
-- [x] ...
-
-The change is implemented! One more step—let's archive it.
-```
-
----
-
-## Phase 10: Archive
-
-**EXPLAIN:**
-```
-## Archiving
-
-When a change is complete, we archive it. This moves it from `openspec/changes/` to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
-
-Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
-```
-
-**DO:**
-```bash
-openspec archive "<name>"
-```
-
-**SHOW:**
-```
-Archived to: `openspec/changes/archive/YYYY-MM-DD-<name>/`
-
-The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
-```
-
----
-
-## Phase 11: Recap & Next Steps
-
-```
-## Congratulations!
-
-You just completed a full OpenSpec cycle:
-
-1. **Explore** - Thought through the problem
-2. **New** - Created a change container
-3. **Proposal** - Captured WHY
-4. **Specs** - Defined WHAT in detail
-5. **Design** - Decided HOW
-6. **Tasks** - Broke it into steps
-7. **Apply** - Implemented the work
-8. **Archive** - Preserved the record
-
-This same rhythm works for any size change—a small fix or a major feature.

----
-
-## What's Next?
-
-Try `/opsx:new` or `/opsx:ff` on something you actually want to build. You've got the rhythm now!
-```
-
----
-
-## Graceful Exit Handling
-
-### User wants to stop mid-way
-
-If the user says they need to stop, want to pause, or seem disengaged:
-
-```
-No problem! Your change is saved at `openspec/changes/<name>/`.
-
-To pick up where we left off later:
-- `/opsx:continue <name>` - Resume artifact creation
-- `/opsx:apply <name>` - Jump to implementation (if tasks exist)
-
-The work won't be lost. Come back whenever you're ready.
-```
-
-Exit gracefully without pressure.
-
-### User just wants command reference
-
-If the user says they just want to see the commands or skip the tutorial:
-
-```
-## OpenSpec Quick Reference
-
-| Command | What it does |
-|---------|--------------|
-| `/opsx:explore` | Think through problems (no code changes) |
-| `/opsx:new <name>` | Start a new change, step by step |
-| `/opsx:ff <name>` | Fast-forward: all artifacts at once |
-| `/opsx:continue <name>` | Continue an existing change |
-| `/opsx:apply <name>` | Implement tasks |
-| `/opsx:verify <name>` | Verify implementation |
-| `/opsx:archive <name>` | Archive when done |

-
-## Guardrails
-
-- **Follow the EXPLAIN → DO → SHOW → PAUSE pattern** at key transitions (after explore, after proposal draft, after tasks, after archive)
-- **Keep narration light** during implementation—teach without lecturing
-- **Don't skip phases** even if the change is small—the goal is teaching the workflow
-- **Pause for acknowledgment** at marked points, but don't over-pause
-- **Handle exits gracefully**—never pressure the user to continue
-- **Use real codebase tasks**—don't simulate or use fake examples
-- **Adjust scope gently**—guide toward smaller tasks but respect user choice

-description: Sync delta specs from a change to main specs
----
-
-Sync delta specs from a change to main specs.
-
-This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
-
-**Input**: Optionally specify a change name after `/opsx:sync` (e.g., `/opsx:sync add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have delta specs (under `specs/` directory).
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Find delta specs**
-
-   Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
-
-   Each delta spec file contains sections like:
-   - `## ADDED Requirements` - New requirements to add
-   - `## MODIFIED Requirements` - Changes to existing requirements
-   - `## REMOVED Requirements` - Requirements to remove
-   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
-
-   If no delta specs found, inform user and stop.
-
-3. **For each delta spec, apply changes to main specs**
-
-   For each capability with a delta spec at `openspec/changes/<name>/specs/<capability>/spec.md`:
-
-   a. **Read the delta spec** to understand the intended changes
-
-   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
-
-   c. **Apply changes intelligently**:
-
-      **ADDED Requirements:**
-      - If requirement doesn't exist in main spec → add it
-      - If requirement already exists → update it to match (treat as implicit MODIFIED)
-
-      **MODIFIED Requirements:**
-      - Find the requirement in main spec
-      - Apply the changes - this can be:
-        - Adding new scenarios (don't need to copy existing ones)
-        - Modifying existing scenarios
-        - Changing the requirement description
-      - Preserve scenarios/content not mentioned in the delta
-
-      **REMOVED Requirements:**
-      - Remove the entire requirement block from main spec
-
-      **RENAMED Requirements:**
-      - Find the FROM requirement, rename to TO
-
-   d. **Create new main spec** if capability doesn't exist yet:
-      - Create `openspec/specs/<capability>/spec.md`
-      - Add Purpose section (can be brief, mark as TBD)
-      - Add Requirements section with the ADDED requirements
-
-4. **Show summary**
-
-   After applying all changes, summarize:
-   - Which capabilities were updated
-   - What changes were made (requirements added/modified/removed/renamed)
-
-**Delta Spec Format Reference**
-
-```markdown
-## ADDED Requirements
-
-### Requirement: New Feature
-The system SHALL do something new.
-
-#### Scenario: Basic case
-- **WHEN** user does X
-- **THEN** system does Y
-
-## MODIFIED Requirements
-
-### Requirement: Existing Feature
-#### Scenario: New scenario to add
-- **WHEN** user does A
-- **THEN** system does B
-
-## REMOVED Requirements
-
-### Requirement: Deprecated Feature
-
-## RENAMED Requirements
-
-- FROM: `### Requirement: Old Name`
-- TO: `### Requirement: New Name`
-```
-
-**Key Principle: Intelligent Merging**
-
-Unlike programmatic merging, you can apply **partial updates**:
-- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
-- The delta represents *intent*, not a wholesale replacement
-- Use your judgment to merge changes sensibly
-
-**Output On Success**
-
-```
-## Specs Synced: <change-name>
-
-Updated main specs:
-
-**<capability-1>**:
-- Added requirement: "New Feature"
-- Modified requirement: "Existing Feature" (added 1 scenario)
-
-**<capability-2>**:
-- Created new spec file
-- Added requirement: "Another Feature"
-
-Main specs are now updated. The change remains active - archive when implementation is complete.
-```
-
-**Guardrails**
-- Read both delta and main specs before making changes
-- Preserve existing content not mentioned in delta
-- If something is unclear, ask for clarification
-- Show what you're changing as you go
-- The operation should be idempotent - running twice should give same result

-description: Verify implementation matches change artifacts before archiving
----
-
-Verify that an implementation matches the change artifacts (specs, tasks, design).
-
-**Input**: Optionally specify a change name after `/opsx:verify` (e.g., `/opsx:verify add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have implementation tasks (tasks artifact exists).
-   Include the schema used for each change if available.
-   Mark changes with incomplete tasks as "(In Progress)".
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - Which artifacts exist for this change
-
-3. **Get the change directory and load artifacts**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns the change directory and context files. Read all available artifacts from `contextFiles`.
-
-4. **Initialize verification report structure**
-
-   Create a report structure with three dimensions:
-   - **Completeness**: Track tasks and spec coverage
-   - **Correctness**: Track requirement implementation and scenario coverage
-   - **Coherence**: Track design adherence and pattern consistency
-
-   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
-
-5. **Verify Completeness**
-
-   **Task Completion**:
-   - If tasks.md exists in contextFiles, read it
-   - Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
-   - Count complete vs total tasks
-   - If incomplete tasks exist:
-     - Add CRITICAL issue for each incomplete task
-     - Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
-
-   **Spec Coverage**:
-   - If delta specs exist in `openspec/changes/<name>/specs/`:
-     - Extract all requirements (marked with "### Requirement:")
-     - For each requirement:
-       - Search codebase for keywords related to the requirement
-       - Assess if implementation likely exists
-     - If requirements appear unimplemented:
-       - Add CRITICAL issue: "Requirement not found: <requirement name>"
-       - Recommendation: "Implement requirement X: <description>"
-
-6. **Verify Correctness**
-
-   **Requirement Implementation Mapping**:
-   - For each requirement from delta specs:
-     - Search codebase for implementation evidence
-     - If found, note file paths and line ranges
-     - Assess if implementation matches requirement intent
-     - If divergence detected:
-       - Add WARNING: "Implementation may diverge from spec: <details>"
-       - Recommendation: "Review <file>:<lines> against requirement X"
-
-   **Scenario Coverage**:
-   - For each scenario in delta specs (marked with "#### Scenario:"):
-     - Check if conditions are handled in code
-     - Check if tests exist covering the scenario
-     - If scenario appears uncovered:
-       - Add WARNING: "Scenario not covered: <scenario name>"
-       - Recommendation: "Add test or implementation for scenario: <description>"
-
-7. **Verify Coherence**
-
-   **Design Adherence**:
-   - If design.md exists in contextFiles:
-     - Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
-     - Verify implementation follows those decisions
-     - If contradiction detected:
-       - Add WARNING: "Design decision not followed: <decision>"
-       - Recommendation: "Update implementation or revise design.md to match reality"
-   - If no design.md: Skip design adherence check, note "No design.md to verify against"
-
-   **Code Pattern Consistency**:
-   - Review new code for consistency with project patterns
-   - Check file naming, directory structure, coding style
-   - If significant deviations found:
-     - Add SUGGESTION: "Code pattern deviation: <details>"
-     - Recommendation: "Consider following project pattern: <example>"
-
-8. **Generate Verification Report**
-
-   **Summary Scorecard**:
-   ```
-   ## Verification Report: <change-name>
-
-   ### Summary
-   | Dimension    | Status           |
-   |--------------|------------------|
-   | Completeness | X/Y tasks, N reqs|
-   | Correctness  | M/N reqs covered |
-   | Coherence    | Followed/Issues  |
-   ```
-
-   **Issues by Priority**:
-
-   1. **CRITICAL** (Must fix before archive):
-      - Incomplete tasks
-      - Missing requirement implementations
-      - Each with specific, actionable recommendation
-
-   2. **WARNING** (Should fix):
-      - Spec/design divergences
-      - Missing scenario coverage
-      - Each with specific recommendation
-
-   3. **SUGGESTION** (Nice to fix):
-      - Pattern inconsistencies
-      - Minor improvements
-      - Each with specific recommendation
-
-   **Final Assessment**:
-   - If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
-   - If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
-   - If all clear: "All checks passed. Ready for archive."
-
-**Verification Heuristics**
-
-- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
-- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
-- **Coherence**: Look for glaring inconsistencies, don't nitpick style
-- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
-- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
-
-**Graceful Degradation**
-
-- If only tasks.md exists: verify task completion only, skip spec/design checks
-- If tasks + specs exist: verify completeness and correctness, skip design
-- If full artifacts: verify all three dimensions
-- Always note which checks were skipped and why
-
-**Output Format**
-
-Use clear markdown with:
-- Table for summary scorecard
-- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
-- Code references in format: `file.ts:123`
-- Specific, actionable recommendations
-- No vague suggestions like "consider reviewing"

----
-
-Implement tasks from an OpenSpec change.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **Select the change**
-
-   If a name is provided, use it. Otherwise:
-   - Infer from conversation context if the user mentioned a change
-   - Auto-select if only one active change exists
-   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
-
-   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
-
-3. **Get apply instructions**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns:
-   - Context file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
-   - Progress (total, complete, remaining)
-   - Task list with status
-   - Dynamic instruction based on current state
-
-   **Handle states:**
-   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
-   - If `state: "all_done"`: congratulate, suggest archive
-   - Otherwise: proceed to implementation
-
-4. **Read context files**
-
-   Read the files listed in `contextFiles` from the apply instructions output.
-   The files depend on the schema being used:
-   - **spec-driven**: proposal, specs, design, tasks
-   - Other schemas: follow the contextFiles from CLI output
-
-5. **Show current progress**
-
-   Display:
-   - Schema being used
-   - Progress: "N/M tasks complete"
-   - Remaining tasks overview
-   - Dynamic instruction from CLI
-
-6. **Implement tasks (loop until done or blocked)**
-
-   For each pending task:
-   - Show which task is being worked on
-   - Make the code changes required
-   - Keep changes minimal and focused
-   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
-   - Continue to next task
-
-   **Pause if:**
-   - Task is unclear → ask for clarification
-   - Implementation reveals a design issue → suggest updating artifacts
-   - Error or blocker encountered → report and wait for guidance
-   - User interrupts
-
-7. **On completion or pause, show status**
-
-   Display:
-   - Tasks completed this session
-   - Overall progress: "N/M tasks complete"
-   - If all done: suggest archive
-   - If paused: explain why and wait for guidance
-
-**Output During Implementation**
-
-```
-## Implementing: <change-name> (schema: <schema-name>)

-```
-
-**Guardrails**
-- Keep going through tasks until done or blocked
-- Always read context files before starting (from the apply instructions output)
-- If task is ambiguous, pause and ask before implementing
-- If implementation reveals issues, pause and suggest artifact updates
-- Keep code changes minimal and scoped to each task
-- Update task checkbox immediately after completing each task
-- Pause on errors, blockers, or unclear requirements - don't guess
-- Use contextFiles from CLI output, don't assume specific file names
-
-**Fluid Workflow Integration**
-
-This skill supports the "actions on a change" model:
-
-- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
-- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

-
-Archive a completed change in the experimental workflow.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show only active changes (not already archived).
-   Include the schema used for each change if available.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check artifact completion status**
-
-   Run `openspec status --change "<name>" --json` to check artifact completion.
-
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used
-   - `artifacts`: List of artifacts with their status (`done` or other)
-
-   **If any artifacts are not `done`:**
-   - Display warning listing incomplete artifacts
-   - Use **AskUserQuestion tool** to confirm user wants to proceed
-   - Proceed if user confirms
-
-3. **Check task completion status**
-
-   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
-
-   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
-
-   **If incomplete tasks found:**
-   - Display warning showing count of incomplete tasks
-   - Use **AskUserQuestion tool** to confirm user wants to proceed
-   - Proceed if user confirms
-
-   **If no tasks file exists:** Proceed without task-related warning.
-
-4. **Assess delta spec sync state**
-
-   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
-
-   **If delta specs exist:**
-   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
-   - Determine what changes would be applied (adds, modifications, removals, renames)
-   - Show a combined summary before prompting
-
-   **Prompt options:**
-   - If changes needed: "Sync now (recommended)", "Archive without syncing"
-   - If already synced: "Archive now", "Sync anyway", "Cancel"
-
-   If user chooses sync, execute /opsx:sync logic (use the openspec-sync-specs skill). Proceed to archive regardless of choice.
-
-5. **Perform the archive**
-
-   Create the archive directory if it doesn't exist:
-   ```bash
-   mkdir -p openspec/changes/archive
-   ```
-
-   Generate target name using current date: `YYYY-MM-DD-<change-name>`
-
-   **Check if target already exists:**
-   - If yes: Fail with error, suggest renaming existing archive or using different date
-   - If no: Move the change directory to archive
-
-   ```bash
-   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
-   ```
-
-6. **Display summary**
-
-   Show archive completion summary including:
-   - Change name
-   - Schema that was used
-   - Archive location
-   - Whether specs were synced (if applicable)
-   - Note about any warnings (incomplete artifacts/tasks)
-
-**Output On Success**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
-**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
-
-All artifacts complete. All tasks complete.
-```
-
-**Guardrails**
-- Always prompt for change selection if not provided
-- Use artifact graph (openspec status --json) for completion checking
-- Don't block archive on warnings - just inform and confirm
-- Preserve .openspec.yaml when moving to archive (it moves with the directory)
-- Show clear summary of what happened
-- If sync is requested, use openspec-sync-specs approach (agent-driven)
-- If delta specs exist, always run the sync assessment and show the combined summary before prompting

----
-
-Archive multiple completed changes in a single operation.
-
-This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.
-
-**Input**: None required (prompts for selection)
-
-**Steps**
-
-1. **Get active changes**
-
-   Run `openspec list --json` to get all active changes.
-
-   If no active changes exist, inform user and stop.
-
-2. **Prompt for change selection**
-
-   Use **AskUserQuestion tool** with multi-select to let user choose changes:
-   - Show each change with its schema
-   - Include an option for "All changes"
-   - Allow any number of selections (1+ works, 2+ is the typical use case)
-
-   **IMPORTANT**: Do NOT auto-select. Always let the user choose.
-
-3. **Batch validation - gather status for all selected changes**
-
-   For each selected change, collect:
-
-   a. **Artifact status** - Run `openspec status --change "<name>" --json`
-      - Parse `schemaName` and `artifacts` list
-      - Note which artifacts are `done` vs other states
-
-   b. **Task completion** - Read `openspec/changes/<name>/tasks.md`
-      - Count `- [ ]` (incomplete) vs `- [x]` (complete)
-      - If no tasks file exists, note as "No tasks"
-
-   c. **Delta specs** - Check `openspec/changes/<name>/specs/` directory
-      - List which capability specs exist
-      - For each, extract requirement names (lines matching `### Requirement: <name>`)
-
-4. **Detect spec conflicts**
-
-   Build a map of `capability -> [changes that touch it]`:
-
-   ```
-   auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
-   api  -> [change-c]            <- OK (only 1 change)
-   ```
-
-   A conflict exists when 2+ selected changes have delta specs for the same capability.
-
-5. **Resolve conflicts agentically**
-
-   **For each conflict**, investigate the codebase:
-
-   a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
-
-   b. **Search the codebase** for implementation evidence:
-      - Look for code implementing requirements from each delta spec
-      - Check for related files, functions, or tests
-
-   c. **Determine resolution**:
-      - If only one change is actually implemented -> sync that one's specs
-      - If both implemented -> apply in chronological order (older first, newer overwrites)
-      - If neither implemented -> skip spec sync, warn user
-
-   d. **Record resolution** for each conflict:
-      - Which change's specs to apply
-      - In what order (if both)
-      - Rationale (what was found in codebase)
-
-6. **Show consolidated status table**
-
-   Display a table summarizing all changes:
-
-   ```
-   | Change               | Artifacts | Tasks | Specs   | Conflicts | Status |
-   |---------------------|-----------|-------|---------|-----------|--------|
-   | schema-management   | Done      | 5/5   | 2 delta | None      | Ready  |
-   | project-config      | Done      | 3/3   | 1 delta | None      | Ready  |
-   | add-oauth           | Done      | 4/4   | 1 delta | auth (!)  | Ready* |
-   | add-verify-skill    | 1 left    | 2/5   | None    | None      | Warn   |
-   ```
-
-   For conflicts, show the resolution:
-   ```
-   * Conflict resolution:
-     - auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
-   ```
-
-   For incomplete changes, show warnings:
-   ```
-   Warnings:
-   - add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
-   ```
-
-7. **Confirm batch operation**
-
-   Use **AskUserQuestion tool** with a single confirmation:
-
-   - "Archive N changes?" with options based on status
-   - Options might include:
-     - "Archive all N changes"
-     - "Archive only N ready changes (skip incomplete)"
-     - "Cancel"
-
-   If there are incomplete changes, make clear they'll be archived with warnings.
-
-8. **Execute archive for each confirmed change**
-
-   Process changes in the determined order (respecting conflict resolution):
-
-   a. **Sync specs** if delta specs exist:
-      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
-      - For conflicts, apply in resolved order
-      - Track if sync was done
-
-   b. **Perform the archive**:
-      ```bash
-      mkdir -p openspec/changes/archive
-      mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
-      ```
-
-   c. **Track outcome** for each change:
-      - Success: archived successfully
-      - Failed: error during archive (record error)
-      - Skipped: user chose not to archive (if applicable)
-
-9. **Display summary**
-
-   Show final results:
-
-   ```
-   ## Bulk Archive Complete
-
-   Archived 3 changes:
-   - schema-management-cli -> archive/2026-01-19-schema-management-cli/
-   - project-config -> archive/2026-01-19-project-config/
-   - add-oauth -> archive/2026-01-19-add-oauth/
-
-   Skipped 1 change:
-   - add-verify-skill (user chose not to archive incomplete)
-
-   Spec sync summary:
-   - 4 delta specs synced to main specs
-   - 1 conflict resolved (auth: applied both in chronological order)
-   ```
-
-   If any failures:
-   ```
-   Failed 1 change:
-   - some-change: Archive directory already exists
-   ```
-
-**Conflict Resolution Examples**
-
-Example 1: Only one implemented
-```
-Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
-
-Checking add-oauth:
-- Delta adds "OAuth Provider Integration" requirement
-- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
-
-Checking add-jwt:
-- Delta adds "JWT Token Handling" requirement
-- Searching codebase... no JWT implementation found
-
-Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
-```
-
-Example 2: Both implemented
-```
-Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
-
-Checking add-rest-api (created 2026-01-10):
-- Delta adds "REST Endpoints" requirement
-- Searching codebase... found src/api/rest.ts
-
-Checking add-graphql (created 2026-01-15):
-- Delta adds "GraphQL Schema" requirement
-- Searching codebase... found src/api/graphql.ts
-
-Resolution: Both implemented. Will apply add-rest-api specs first,
-then add-graphql specs (chronological order, newer takes precedence).
-```
-
-**Output On Success**
-
-```
-## Bulk Archive Complete
-
-Archived N changes:
-- <change-1> -> archive/YYYY-MM-DD-<change-1>/
-- <change-2> -> archive/YYYY-MM-DD-<change-2>/
-
-Spec sync summary:
-- N delta specs synced to main specs
-- No conflicts (or: M conflicts resolved)
-```
-
-**Output On Partial Success**
-
-```
-## Bulk Archive Complete (partial)
-
-Archived N changes:
-- <change-1> -> archive/YYYY-MM-DD-<change-1>/
-
-Skipped M changes:
-- <change-2> (user chose not to archive incomplete)
-
-Failed K changes:
-- <change-3>: Archive directory already exists
-```
-
-**Output When No Changes**
-
-```
-## No Changes to Archive
-
-No active changes found. Use `/opsx:new` to create a new change.
-```
-
-**Guardrails**
-- Allow any number of changes (1+ is fine, 2+ is the typical use case)
-- Always prompt for selection, never auto-select
-- Detect spec conflicts early and resolve by checking codebase
-- When both changes are implemented, apply specs in chronological order
-- Skip spec sync only when implementation is missing (warn user)
-- Show clear per-change status before confirming
-- Use single confirmation for entire batch
-- Track and report all outcomes (success/skip/fail)
-- Preserve .openspec.yaml when moving to archive
-- Archive directory target uses current date: YYYY-MM-DD-<name>
-- If archive target exists, fail that change but continue with others

-Continue working on a change by creating the next artifact.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes sorted by most recently modified. Then use the **AskUserQuestion tool** to let the user select which change to work on.
-
-   Present the top 3-4 most recently modified changes as options, showing:
-   - Change name
-   - Schema (from `schema` field if present, otherwise "spec-driven")
-   - Status (e.g., "0/5 tasks", "complete", "no tasks")
-   - How recently it was modified (from `lastModified` field)
-
-   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check current status**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand current state. The response includes:
-   - `schemaName`: The workflow schema being used (e.g., "spec-driven")
-   - `artifacts`: Array of artifacts with their status ("done", "ready", "blocked")
-   - `isComplete`: Boolean indicating if all artifacts are complete
-
-3. **Act based on status**:
-
-   ---
-
-   **If all artifacts are complete (`isComplete: true`)**:
-   - Congratulate the user
-   - Show final status including the schema used
-   - Suggest: "All artifacts created! You can now implement this change or archive it."
-   - STOP
-
-   ---
-
-   **If artifacts are ready to create** (status shows artifacts with `status: "ready"`):
-   - Pick the FIRST artifact with `status: "ready"` from the status output
-   - Get its instructions:
-     ```bash
-     openspec instructions <artifact-id> --change "<name>" --json
-     ```
-   - Parse the JSON. The key fields are:
-     - `context`: Project background (constraints for you - do NOT include in output)
-     - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-     - `template`: The structure to use for your output file
-     - `instruction`: Schema-specific guidance
-     - `outputPath`: Where to write the artifact
-     - `dependencies`: Completed artifacts to read for context
-   - **Create the artifact file**:
-     - Read any completed dependency files for context
-     - Use `template` as the structure - fill in its sections
-     - Apply `context` and `rules` as constraints when writing - but do NOT copy them into the file
-     - Write to the output path specified in instructions
-   - Show what was created and what's now unlocked
-   - STOP after creating ONE artifact
-
-   ---
-
-   **If no artifacts are ready (all blocked)**:
-   - This shouldn't happen with a valid schema
-   - Show status and suggest checking for issues
-
-4. **After creating an artifact, show progress**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After each invocation, show:
-- Which artifact was created
-- Schema workflow being used
-- Current progress (N/M complete)
-- What artifacts are now unlocked
-- Prompt: "Want to continue? Just ask me to continue or tell me what to do next."
-
-**Artifact Creation Guidelines**
-
-The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
-
-Common artifact patterns:
-
-**spec-driven schema** (proposal → specs → design → tasks):
-- **proposal.md**: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
-  - The Capabilities section is critical - each capability listed will need a spec file.
-- **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
-- **design.md**: Document technical decisions, architecture, and implementation approach.
-- **tasks.md**: Break down implementation into checkboxed tasks.
-
-For other schemas, follow the `instruction` field from the CLI output.
-
-**Guardrails**
-- Create ONE artifact per invocation
-- Always read dependency artifacts before creating a new one
-- Never skip artifacts or create out of order
-- If context is unclear, ask the user before creating
-- Verify the artifact file exists after writing before marking progress
-- Use the schema's artifact sequence, don't assume specific artifact names
-- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
-  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
-  - These guide what you write, but should never appear in the output

----
-
-Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
-
-**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first (e.g., start a change with `/opsx:new` or `/opsx:ff`). You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
-
-**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
-
----
-
-## The Stance
-
-- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
-- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
-- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
-- **Adaptive** - Follow interesting threads, pivot when new information emerges
-- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
-- **Grounded** - Explore the actual codebase when relevant, don't just theorize
-
----
-
-## What You Might Do
-
-Depending on what the user brings, you might:
-
-**Explore the problem space**
-- Ask clarifying questions that emerge from what they said
-- Challenge assumptions
-- Reframe the problem
-- Find analogies
-
-**Investigate the codebase**
-- Map existing architecture relevant to the discussion
-- Find integration points
-- Identify patterns already in use
-- Surface hidden complexity
-
-**Compare options**
-- Brainstorm multiple approaches
-- Build comparison tables
-- Sketch tradeoffs
-- Recommend a path (if asked)
-
-**Visualize**
-```

----
-
-## OpenSpec Awareness
-
-You have full context of the OpenSpec system. Use it naturally, don't force it.
-
-### Check for context
-
-At the start, quickly check what exists:
-```bash
-openspec list --json
-```
-
-This tells you:
-- If there are active changes
-- Their names, schemas, and status
-- What the user might be working on
-
-### When no change exists
-
-Think freely. When insights crystallize, you might offer:
-
-- "This feels solid enough to start a change. Want me to create one?"
-  → Can transition to `/opsx:new` or `/opsx:ff`
-- Or keep exploring - no pressure to formalize
-
-### When a change exists
-
-If the user mentions a change or you detect one is relevant:
-
-1. **Read existing artifacts for context**
-   - `openspec/changes/<name>/proposal.md`
-   - `openspec/changes/<name>/design.md`
-   - `openspec/changes/<name>/tasks.md`
-   - etc.
-
-2. **Reference them naturally in conversation**
-   - "Your design mentions using Redis, but we just realized SQLite fits better..."
-   - "The proposal scopes this to premium users, but we're now thinking everyone..."
-
-3. **Offer to capture when decisions are made**
-
-   | Insight Type | Where to Capture |
-   |--------------|------------------|
-   | New requirement discovered | `specs/<capability>/spec.md` |
-   | Requirement changed | `specs/<capability>/spec.md` |
-   | Design decision made | `design.md` |
-   | Scope changed | `proposal.md` |
-   | New work identified | `tasks.md` |
-   | Assumption invalidated | Relevant artifact |
-
-   Example offers:
-   - "That's a design decision. Capture it in design.md?"
-   - "This is a new requirement. Add it to specs?"
-   - "This changes scope. Update the proposal?"
-
-4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
-
----
-
-## What You Don't Have To Do
-
-- Follow a script
-- Ask the same questions every time
-- Produce a specific artifact
-- Reach a conclusion
-- Stay on topic if a tangent is valuable
-- Be brief (this is thinking time)
-
----
-
-## Handling Different Entry Points

-## Ending Discovery
-
-There's no required ending. Discovery might:
-
-- **Flow into action**: "Ready to start? /opsx:new or /opsx:ff"
-- **Result in artifact updates**: "Updated design.md with these decisions"
-- **Just provide clarity**: User has what they need, moves on
-- **Continue later**: "We can pick this up anytime"
-
-When it feels like things are crystallizing, you might summarize:
-
-```
-## What We Figured Out
-
-**The problem**: [crystallized understanding]
-
-**The approach**: [if one emerged]
-
-**Open questions**: [if any remain]
-
-**Next steps** (if ready):
-- Create a change: /opsx:new <name>
-- Fast-forward to tasks: /opsx:ff <name>
-- Keep exploring: just keep talking
-```
-
-But this summary is optional. Sometimes the thinking IS the value.
-
----
-
-## Guardrails
-
-- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
-- **Don't fake understanding** - If something is unclear, dig deeper
-- **Don't rush** - Discovery is thinking time, not task time
-- **Don't force structure** - Let patterns emerge naturally
-- **Don't auto-capture** - Offer to save insights, don't just do it
-- **Do visualize** - A good diagram is worth many paragraphs
-- **Do explore the codebase** - Ground discussions in reality
-- **Do question assumptions** - Including the user's and your own

----
-
-Fast-forward through artifact creation - generate everything needed to start implementation in one go.
-
-**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
-
-**Steps**
-
-1. **If no clear input provided, ask what they want to build**
-
-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."
-
-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   This creates a scaffolded change at `openspec/changes/<name>/`.
-
-3. **Get the artifact build order**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to get:
-   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
-   - `artifacts`: list of all artifacts with their status and dependencies
-
-4. **Create artifacts in sequence until apply-ready**
-
-   Use the **TodoWrite tool** to track progress through the artifacts.
-
-   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
-
-   a. **For each artifact that is `ready` (dependencies satisfied)**:
-      - Get instructions:
-        ```bash
-        openspec instructions <artifact-id> --change "<name>" --json
-        ```
-      - The instructions JSON includes:
-        - `context`: Project background (constraints for you - do NOT include in output)
-        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-        - `template`: The structure to use for your output file
-        - `instruction`: Schema-specific guidance for this artifact type
-        - `outputPath`: Where to write the artifact
-        - `dependencies`: Completed artifacts to read for context
-      - Read any completed dependency files for context
-      - Create the artifact file using `template` as the structure
-      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
-      - Show brief progress: "✓ Created <artifact-id>"
-
-   b. **Continue until all `applyRequires` artifacts are complete**
-      - After creating each artifact, re-run `openspec status --change "<name>" --json`
-      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
-      - Stop when all `applyRequires` artifacts are done
-
-   c. **If an artifact requires user input** (unclear context):
-      - Use **AskUserQuestion tool** to clarify
-      - Then continue with creation
-
-5. **Show final status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After completing all artifacts, summarize:
-- Change name and location
-- List of artifacts created with brief descriptions
-- What's ready: "All artifacts created! Ready for implementation."
-- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
-
-**Artifact Creation Guidelines**
-
-- Follow the `instruction` field from `openspec instructions` for each artifact type
-- The schema defines what each artifact should contain - follow it
-- Read dependency artifacts for context before creating new ones
-- Use `template` as the structure for your output file - fill in its sections
-- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
-  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
-  - These guide what you write, but should never appear in the output
-
-**Guardrails**
-- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
-- Always read dependency artifacts before creating a new one
-- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
-- If a change with that name already exists, suggest continuing that change instead
-- Verify each artifact file exists after writing before proceeding to next

-
-Start a new change using the experimental artifact-driven approach.
-
-**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
-
-**Steps**
-
-1. **If no clear input provided, ask what they want to build**
-
-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."
-
-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Determine the workflow schema**
-
-   Use the default schema (omit `--schema`) unless the user explicitly requests a different workflow.
-
-   **Use a different schema only if the user mentions:**
-   - A specific schema name → use `--schema <name>`
-   - "show workflows" or "what workflows" → run `openspec schemas --json` and let them choose
-
-   **Otherwise**: Omit `--schema` to use the default.
-
-3. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   Add `--schema <name>` only if the user requested a specific workflow.
-   This creates a scaffolded change at `openspec/changes/<name>/` with the selected schema.
-
-4. **Show the artifact status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-   This shows which artifacts need to be created and which are ready (dependencies satisfied).
-
-5. **Get instructions for the first artifact**
-   The first artifact depends on the schema (e.g., `proposal` for spec-driven).
-   Check the status output to find the first artifact with status "ready".
-   ```bash
-   openspec instructions <first-artifact-id> --change "<name>"
-   ```
-   This outputs the template and context for creating the first artifact.
-
-6. **STOP and wait for user direction**
-
-**Output**
-
-After completing the steps, summarize:
-- Change name and location
-- Schema/workflow being used and its artifact sequence
-- Current status (0/N artifacts complete)
-- The template for the first artifact
-- Prompt: "Ready to create the first artifact? Just describe what this change is about and I'll draft it, or ask me to continue."
-
-**Guardrails**
-- Do NOT create any artifacts yet - just show the instructions
-- Do NOT advance beyond showing the first artifact template
-- If the name is invalid (not kebab-case), ask for a valid name
-- If a change with that name already exists, suggest continuing that change instead
-- Pass --schema if using a non-default workflow

-metadata:
-  author: openspec
-  version: "1.0"
-  generatedBy: "1.1.1"
----
-
-Guide the user through their first complete OpenSpec workflow cycle. This is a teaching experience—you'll do real work in their codebase while explaining each step.
-
----
-
-## Preflight
-
-Before starting, check if OpenSpec is initialized:
-
-```bash
-openspec status --json 2>&1 || echo "NOT_INITIALIZED"
-```
-
-**If not initialized:**
-> OpenSpec isn't set up in this project yet. Run `openspec init` first, then come back to `/opsx:onboard`.
-
-Stop here if not initialized.
-
----
-
-## Phase 1: Welcome
-
-Display:
-
-```
-## Welcome to OpenSpec!
-
-I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
-
-**What we'll do:**
-1. Pick a small, real task in your codebase
-2. Explore the problem briefly
-3. Create a change (the container for our work)
-4. Build the artifacts: proposal → specs → design → tasks
-5. Implement the tasks
-6. Archive the completed change
-
-**Time:** ~15-20 minutes
-
-Let's start by finding something to work on.
-```
-
----
-
-## Phase 2: Task Selection
-
-### Codebase Analysis
-
-Scan the codebase for small improvement opportunities. Look for:
-
-1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
-2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
-3. **Functions without tests** - Cross-reference `src/` with test directories
-4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
-5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
-6. **Missing validation** - User input handlers without validation
-
-Also check recent git activity:
-```bash
-git log --oneline -10 2>/dev/null || echo "No git history"
-```
-
-### Present Suggestions
-
-From your analysis, present 3-4 specific suggestions:
-
-```
-## Task Suggestions
-
-Based on scanning your codebase, here are some good starter tasks:
-
-**1. [Most promising task]**
-   Location: `src/path/to/file.ts:42`
-   Scope: ~1-2 files, ~20-30 lines
-   Why it's good: [brief reason]
-
-**2. [Second task]**
-   Location: `src/another/file.ts`
-   Scope: ~1 file, ~15 lines
-   Why it's good: [brief reason]
-
-**3. [Third task]**
-   Location: [location]
-   Scope: [estimate]
-   Why it's good: [brief reason]
-
-**4. Something else?**
-   Tell me what you'd like to work on.
-
-Which task interests you? (Pick a number or describe your own)
-```
-
-**If nothing found:** Fall back to asking what the user wants to build:
-> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
-
-### Scope Guardrail
-
-If the user picks or describes something too large (major feature, multi-day work):
-
-```
-That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
-
-For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
-
-**Options:**
-1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
-2. **Pick something else** - One of the other suggestions, or a different small task?
-3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
-
-What would you prefer?
-```
-
-Let the user override if they insist—this is a soft guardrail.
-
----
-
-## Phase 3: Explore Demo
-
-Once a task is selected, briefly demonstrate explore mode:
-
-```
-Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
-```
-
-Spend 1-2 minutes investigating the relevant code:
-- Read the file(s) involved
-- Draw a quick ASCII diagram if it helps
-- Note any considerations
-
-```
-## Quick Exploration
-
-[Your brief analysis—what you found, any considerations]
-
-┌─────────────────────────────────────────┐
-│   [Optional: ASCII diagram if helpful]  │
-└─────────────────────────────────────────┘
-
-Explore mode (`/opsx:explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
-
-Now let's create a change to hold our work.
-```
-
-**PAUSE** - Wait for user acknowledgment before proceeding.
-
----
-
-## Phase 4: Create the Change
-
-**EXPLAIN:**
-```
-## Creating a Change
-
-A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives in `openspec/changes/<name>/` and holds your artifacts—proposal, specs, design, tasks.
-
-Let me create one for our task.
-```
-
-**DO:** Create the change with a derived kebab-case name:
-```bash
-openspec new change "<derived-name>"
-```
-
-**SHOW:**
-```
-Created: `openspec/changes/<name>/`
-
-The folder structure:
-```
-openspec/changes/<name>/
-├── proposal.md    ← Why we're doing this (empty, we'll fill it)
-├── design.md      ← How we'll build it (empty)
-├── specs/         ← Detailed requirements (empty)
-└── tasks.md       ← Implementation checklist (empty)
-```
-
-Now let's fill in the first artifact—the proposal.
-```
-
----
-
-## Phase 5: Proposal
-
-**EXPLAIN:**
-```
-## The Proposal
-
-The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
-
-I'll draft one based on our task.
-```
-
-**DO:** Draft the proposal content (don't save yet):
-
-```
-Here's a draft proposal:
-
----
-
-## Why
-
-[1-2 sentences explaining the problem/opportunity]
-
-## What Changes
-
-[Bullet points of what will be different]
-
-## Capabilities
-
-### New Capabilities
-- `<capability-name>`: [brief description]
-
-### Modified Capabilities
-<!-- If modifying existing behavior -->
-
-## Impact
-
-- `src/path/to/file.ts`: [what changes]
-- [other files if applicable]
-
----
-
-Does this capture the intent? I can adjust before we save it.
-```
-
-**PAUSE** - Wait for user approval/feedback.
-
-After approval, save the proposal:
-```bash
-openspec instructions proposal --change "<name>" --json
-```
-Then write the content to `openspec/changes/<name>/proposal.md`.
-
-```
-Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
-
-Next up: specs.
-```
-
----
-
-## Phase 6: Specs
-
-**EXPLAIN:**
-```
-## Specs
-
-Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
-
-For a small task like this, we might only need one spec file.
-```
-
-**DO:** Create the spec file:
-```bash
-mkdir -p openspec/changes/<name>/specs/<capability-name>
-```
-
-Draft the spec content:
-
-```
-Here's the spec:
-
----
-
-## ADDED Requirements
-
-### Requirement: <Name>
-
-<Description of what the system should do>
-
-#### Scenario: <Scenario name>
-
-- **WHEN** <trigger condition>
-- **THEN** <expected outcome>
-- **AND** <additional outcome if needed>
-
----
-
-This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
-```
-
-Save to `openspec/changes/<name>/specs/<capability>/spec.md`.
-
----
-
-## Phase 7: Design
-
-**EXPLAIN:**
-```
-## Design
-
-The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
-
-For small changes, this might be brief. That's fine—not every change needs deep design discussion.
-```
-
-**DO:** Draft design.md:
-
-```
-Here's the design:
-
----
-
-## Context
-
-[Brief context about the current state]
-
-## Goals / Non-Goals
-
-**Goals:**
-- [What we're trying to achieve]
-
-**Non-Goals:**
-- [What's explicitly out of scope]
-
-## Decisions
-
-### Decision 1: [Key decision]
-
-[Explanation of approach and rationale]
-
----
-
-For a small task, this captures the key decisions without over-engineering.
-```
-
-Save to `openspec/changes/<name>/design.md`.
-
----
-
-## Phase 8: Tasks
-
-**EXPLAIN:**
-```
-## Tasks
-
-Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
-
-These should be small, clear, and in logical order.
-```
-
-**DO:** Generate tasks based on specs and design:
-
-```
-Here are the implementation tasks:
-
----
-
-## 1. [Category or file]
-
-- [ ] 1.1 [Specific task]
-- [ ] 1.2 [Specific task]
-
-## 2. Verify
-
-- [ ] 2.1 [Verification step]
-
----
-
-Each checkbox becomes a unit of work in the apply phase. Ready to implement?
-```
-
-**PAUSE** - Wait for user to confirm they're ready to implement.
-
-Save to `openspec/changes/<name>/tasks.md`.
-
----
-
-## Phase 9: Apply (Implementation)
-
-**EXPLAIN:**
-```
-## Implementation
-
-Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
-```
-
-**DO:** For each task:
-
-1. Announce: "Working on task N: [description]"
-2. Implement the change in the codebase
-3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
-4. Mark complete in tasks.md: `- [ ]` → `- [x]`
-5. Brief status: "✓ Task N complete"
-
-Keep narration light—don't over-explain every line of code.
-
-After all tasks:
-
-```
-## Implementation Complete
-
-All tasks done:
-- [x] Task 1
-- [x] Task 2
-- [x] ...
-
-The change is implemented! One more step—let's archive it.
-```
-
----
-
-## Phase 10: Archive
-
-**EXPLAIN:**
-```
-## Archiving
-
-When a change is complete, we archive it. This moves it from `openspec/changes/` to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
-
-Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
-```
-
-**DO:**
-```bash
-openspec archive "<name>"
-```
-
-**SHOW:**
-```
-Archived to: `openspec/changes/archive/YYYY-MM-DD-<name>/`
-
-The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
-```
-
----
-
-## Phase 11: Recap & Next Steps
-
-```
-## Congratulations!

-You just completed a full OpenSpec cycle:
-
-1. **Explore** - Thought through the problem
-2. **New** - Created a change container
-3. **Proposal** - Captured WHY
-4. **Specs** - Defined WHAT in detail
-5. **Design** - Decided HOW
-6. **Tasks** - Broke it into steps
-7. **Apply** - Implemented the work
-8. **Archive** - Preserved the record
-
-This same rhythm works for any size change—a small fix or a major feature.
-

-
-## Command Reference
-
-| Command | What it does |
-|---------|--------------|
-| `/opsx:explore` | Think through problems before/during work |
-| `/opsx:new` | Start a new change, step through artifacts |
-| `/opsx:ff` | Fast-forward: create all artifacts at once |
-| `/opsx:continue` | Continue working on an existing change |
-| `/opsx:apply` | Implement tasks from a change |
-| `/opsx:verify` | Verify implementation matches artifacts |
-| `/opsx:archive` | Archive a completed change |
-
----
-
-## What's Next?
-
-Try `/opsx:new` or `/opsx:ff` on something you actually want to build. You've got the rhythm now!
-```
-
----
-
-## Graceful Exit Handling
-
-### User wants to stop mid-way
-
-If the user says they need to stop, want to pause, or seem disengaged:
-
-```
-No problem! Your change is saved at `openspec/changes/<name>/`.
-
-To pick up where we left off later:
-- `/opsx:continue <name>` - Resume artifact creation
-- `/opsx:apply <name>` - Jump to implementation (if tasks exist)
-
-The work won't be lost. Come back whenever you're ready.
-```
-
-Exit gracefully without pressure.
-
-### User just wants command reference
-
-If the user says they just want to see the commands or skip the tutorial:
-
-```
-## OpenSpec Quick Reference
-
-| Command | What it does |
-|---------|--------------|
-| `/opsx:explore` | Think through problems (no code changes) |
-| `/opsx:new <name>` | Start a new change, step by step |
-| `/opsx:ff <name>` | Fast-forward: all artifacts at once |
-| `/opsx:continue <name>` | Continue an existing change |
-| `/opsx:apply <name>` | Implement tasks |
-| `/opsx:verify <name>` | Verify implementation |
-| `/opsx:archive <name>` | Archive when done |
-
-Try `/opsx:new` to start your first change, or `/opsx:ff` if you want to move fast.
-```
-
-Exit gracefully.

-## Guardrails
-
-- **Follow the EXPLAIN → DO → SHOW → PAUSE pattern** at key transitions (after explore, after proposal draft, after tasks, after archive)
-- **Keep narration light** during implementation—teach without lecturing
-- **Don't skip phases** even if the change is small—the goal is teaching the workflow
-- **Pause for acknowledgment** at marked points, but don't over-pause
-- **Handle exits gracefully**—never pressure the user to continue
-- **Use real codebase tasks**—don't simulate or use fake examples
-- **Adjust scope gently**—guide toward smaller tasks but respect user choice

-description: Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
-license: MIT
-compatibility: Requires openspec CLI.
-metadata:
-  author: openspec
-  version: "1.0"

----
-
-Sync delta specs from a change to main specs.
-
-This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have delta specs (under `specs/` directory).
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Find delta specs**
-
-   Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
-
-   Each delta spec file contains sections like:
-   - `## ADDED Requirements` - New requirements to add
-   - `## MODIFIED Requirements` - Changes to existing requirements
-   - `## REMOVED Requirements` - Requirements to remove
-   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
-
-   If no delta specs found, inform user and stop.
-
-3. **For each delta spec, apply changes to main specs**
-
-   For each capability with a delta spec at `openspec/changes/<name>/specs/<capability>/spec.md`:
-
-   a. **Read the delta spec** to understand the intended changes
-
-   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
-
-   c. **Apply changes intelligently**:
-
-      **ADDED Requirements:**
-      - If requirement doesn't exist in main spec → add it
-      - If requirement already exists → update it to match (treat as implicit MODIFIED)
-
-      **MODIFIED Requirements:**
-      - Find the requirement in main spec
-      - Apply the changes - this can be:
-        - Adding new scenarios (don't need to copy existing ones)
-        - Modifying existing scenarios
-        - Changing the requirement description
-      - Preserve scenarios/content not mentioned in the delta
-
-      **REMOVED Requirements:**
-      - Remove the entire requirement block from main spec
-
-      **RENAMED Requirements:**
-      - Find the FROM requirement, rename to TO
-
-   d. **Create new main spec** if capability doesn't exist yet:
-      - Create `openspec/specs/<capability>/spec.md`
-      - Add Purpose section (can be brief, mark as TBD)
-      - Add Requirements section with the ADDED requirements
-
-4. **Show summary**
-
-   After applying all changes, summarize:
-   - Which capabilities were updated
-   - What changes were made (requirements added/modified/removed/renamed)
-
-**Delta Spec Format Reference**
-
-```markdown
-## ADDED Requirements
-
-### Requirement: New Feature
-The system SHALL do something new.
-
-#### Scenario: Basic case
-- **WHEN** user does X
-- **THEN** system does Y
-
-## MODIFIED Requirements
-
-### Requirement: Existing Feature
-#### Scenario: New scenario to add
-- **WHEN** user does A
-- **THEN** system does B
-
-## REMOVED Requirements
-
-### Requirement: Deprecated Feature
-
-## RENAMED Requirements
-
-- FROM: `### Requirement: Old Name`
-- TO: `### Requirement: New Name`
-```
-
-**Key Principle: Intelligent Merging**
-
-Unlike programmatic merging, you can apply **partial updates**:
-- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
-- The delta represents *intent*, not a wholesale replacement
-- Use your judgment to merge changes sensibly
-
-**Output On Success**
-
-```
-## Specs Synced: <change-name>
-
-Updated main specs:
-
-**<capability-1>**:
-- Added requirement: "New Feature"
-- Modified requirement: "Existing Feature" (added 1 scenario)
-
-**<capability-2>**:
-- Created new spec file
-- Added requirement: "Another Feature"
-
-Main specs are now updated. The change remains active - archive when implementation is complete.
-```
-
-**Guardrails**
-- Read both delta and main specs before making changes
-- Preserve existing content not mentioned in delta
-- If something is unclear, ask for clarification
-- Show what you're changing as you go
-- The operation should be idempotent - running twice should give same result

-description: Verify implementation matches change artifacts. Use when the user wants to validate that implementation is complete, correct, and coherent before archiving.
-license: MIT
-compatibility: Requires openspec CLI.
-metadata:
-  author: openspec
-  version: "1.0"
-  generatedBy: "1.1.1"
----
-
-Verify that an implementation matches the change artifacts (specs, tasks, design).
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have implementation tasks (tasks artifact exists).
-   Include the schema used for each change if available.
-   Mark changes with incomplete tasks as "(In Progress)".
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - Which artifacts exist for this change
-
-3. **Get the change directory and load artifacts**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns the change directory and context files. Read all available artifacts from `contextFiles`.
-
-4. **Initialize verification report structure**
-
-   Create a report structure with three dimensions:
-   - **Completeness**: Track tasks and spec coverage
-   - **Correctness**: Track requirement implementation and scenario coverage
-   - **Coherence**: Track design adherence and pattern consistency
-
-   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
-
-5. **Verify Completeness**
-
-   **Task Completion**:
-   - If tasks.md exists in contextFiles, read it
-   - Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
-   - Count complete vs total tasks
-   - If incomplete tasks exist:
-     - Add CRITICAL issue for each incomplete task
-     - Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
-
-   **Spec Coverage**:
-   - If delta specs exist in `openspec/changes/<name>/specs/`:
-     - Extract all requirements (marked with "### Requirement:")
-     - For each requirement:
-       - Search codebase for keywords related to the requirement
-       - Assess if implementation likely exists
-     - If requirements appear unimplemented:
-       - Add CRITICAL issue: "Requirement not found: <requirement name>"
-       - Recommendation: "Implement requirement X: <description>"
-
-6. **Verify Correctness**
-
-   **Requirement Implementation Mapping**:
-   - For each requirement from delta specs:
-     - Search codebase for implementation evidence
-     - If found, note file paths and line ranges
-     - Assess if implementation matches requirement intent
-     - If divergence detected:
-       - Add WARNING: "Implementation may diverge from spec: <details>"
-       - Recommendation: "Review <file>:<lines> against requirement X"
-
-   **Scenario Coverage**:
-   - For each scenario in delta specs (marked with "#### Scenario:"):
-     - Check if conditions are handled in code
-     - Check if tests exist covering the scenario
-     - If scenario appears uncovered:
-       - Add WARNING: "Scenario not covered: <scenario name>"
-       - Recommendation: "Add test or implementation for scenario: <description>"
-
-7. **Verify Coherence**
-
-   **Design Adherence**:
-   - If design.md exists in contextFiles:
-     - Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
-     - Verify implementation follows those decisions
-     - If contradiction detected:
-       - Add WARNING: "Design decision not followed: <decision>"
-       - Recommendation: "Update implementation or revise design.md to match reality"
-   - If no design.md: Skip design adherence check, note "No design.md to verify against"
-
-   **Code Pattern Consistency**:
-   - Review new code for consistency with project patterns
-   - Check file naming, directory structure, coding style
-   - If significant deviations found:
-     - Add SUGGESTION: "Code pattern deviation: <details>"
-     - Recommendation: "Consider following project pattern: <example>"
-
-8. **Generate Verification Report**
-
-   **Summary Scorecard**:
-   ```
-   ## Verification Report: <change-name>
-
-   ### Summary
-   | Dimension    | Status           |
-   |--------------|------------------|
-   | Completeness | X/Y tasks, N reqs|
-   | Correctness  | M/N reqs covered |
-   | Coherence    | Followed/Issues  |
-   ```
-
-   **Issues by Priority**:
-
-   1. **CRITICAL** (Must fix before archive):
-      - Incomplete tasks
-      - Missing requirement implementations
-      - Each with specific, actionable recommendation
-
-   2. **WARNING** (Should fix):
-      - Spec/design divergences
-      - Missing scenario coverage
-      - Each with specific recommendation
-
-   3. **SUGGESTION** (Nice to fix):
-      - Pattern inconsistencies
-      - Minor improvements
-      - Each with specific recommendation
-
-   **Final Assessment**:
-   - If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
-   - If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
-   - If all clear: "All checks passed. Ready for archive."
-
-**Verification Heuristics**
-
-- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
-- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
-- **Coherence**: Look for glaring inconsistencies, don't nitpick style
-- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
-- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
-
-**Graceful Degradation**
-
-- If only tasks.md exists: verify task completion only, skip spec/design checks
-- If tasks + specs exist: verify completeness and correctness, skip design
-- If full artifacts: verify all three dimensions
-- Always note which checks were skipped and why
-
-**Output Format**
-
-Use clear markdown with:
-- Table for summary scorecard
-- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
-- Code references in format: `file.ts:123`
-- Specific, actionable recommendations
-- No vague suggestions like "consider reviewing"

-# Progress Summary - Predefined Query Filters
-
-## Completed Work (2024-12-XX → 2026-02-03)
-
-### 1. Core Filter System ✅
-- Created 18 predefined query filters in `web/utils/filters.py`
-- Organized into 4 categories: Gameplay (5), Ratings (7), Dates (5), Content (2)
-- Added `PREDEFINED_QUERIES`, `QUERY_DISPLAY_NAMES`, `QUERY_CATEGORIES`, `QUERY_DESCRIPTIONS`
-- All 26 unit tests passing
-
-### 2. Backend Query Parameter Handling ✅
-- Added `queries` parameter to all relevant routes:
-  - `library()` - Main library page
-  - `discover()` - Discover page
-  - `collection_detail()` - Collection detail page
-  - `random_game()` - Random game selector
-- Implemented validation and SQL WHERE clause building
-- All filters work with existing store/genre filters
-
-### 3. UI Components and Styling ✅
-- Converted native select dropdowns to custom styled dropdowns for consistent dark theme
-- Added date sorting options (Recently Added, Oldest in Library, Release Date)
-- Created Quick Filters section with category headers
-- Added active state highlighting for selected filters
-
-### 4. Global Filters Architecture ✅
-**Major Feature Addition:**
-- Added "Apply filters globally" checkbox to filter bar
-- Implemented localStorage persistence for global filter state
-- Auto-apply filters on page load (replaces click interception approach)
-- Global filters now work across:
-  - `/library` (Library page)
-  - `/random` (Random game)
-  - `/discover` (Discover page)
-  - `/collections/<id>` (Collection detail pages)
-
-### 5. Reusable Filter Components ✅
-**Major Architecture Refactor:**
-
-Created three reusable components:
-1. **web/templates/_filter_bar.html** (191 lines)
-   - Jinja2 component with filter scope checkbox
-   - Store dropdown with icons and counts
-   - Genre dropdown with search functionality
-   - Quick Filters dropdown with categories
-   - Configurable sections: `show_search`, `show_sort`, `show_actions`
-
-2. **web/static/css/filters.css** (408 lines)
-   - Centralized styling for all filter elements
-   - Custom dropdown animations
-   - Checkbox styling
-   - Responsive design with mobile support
-   - Fixed z-index issue with `margin-top: 80px`
-
-3. **web/static/js/filters.js** (289 lines)
-   - Filter scope management (`getFilterScope()`, `setFilterScope()`, `toggleFilterScope()`)
-   - Auto-apply filters on load (`applyGlobalFiltersOnLoad()`)
-   - Dropdown UI controls (`toggleStoreDropdown()`, `toggleGenreDropdown()`)
-   - URL building (`buildUrl()`)
-   - Filter bar visibility logic (hide on non-library pages when global disabled)
-
-**Updated routes to provide filter context:**
-- `web/routes/discover.py` - Returns store_counts, genre_counts, filter data
-- `web/routes/collections.py` - Returns filter data for collection games
-- `web/routes/library.py` - Already had filter data
-
-**Integrated components into templates:**
-- `web/templates/index.html` (Library page)
-- `web/templates/discover.html` (Discover page)
-- `web/templates/collection_detail.html` (Collection detail page)
-
-### 6. Performance Optimization ✅
-**Discover Page Optimization:**
-- Combined 5 separate SQL queries into 1 UNION ALL query
-- Reduced query count from 8+ to 2
-- Created `popularity_cache` table for IGDB API data:
-  - Columns: `igdb_id`, `popularity_type`, `popularity_value`, `cached_at`
-  - 24-hour cache expiration
-  - Implemented `get_cached_popularity()` and `cache_popularity_data()`
-- Discover page now loads significantly faster
-
-### 7. UI/UX Improvements ✅
-- Fixed dropdown behavior (close all dropdowns when opening another)
-- Fixed z-index issue with filter bar (was hidden under transparent nav)
-- Added filter bar visibility control (hide on non-library pages when global disabled)
-- Tooltips with filter descriptions
-- Category-based filter organization
-- Exclusive category selection (only one filter per category active)
-
-### 8. Code Cleanup ✅
-- `web/templates/index.html` cleaned up (removed ~273 lines of redundant code)
-- All redundant filter-related CSS/JS moved to reusable components
-- File reduced from 1856 to 1583 lines
-- **Status:** Complete
-
-### 9. Reset All Filters Enhancement ✅
-**Completed:** The "Reset all filters" button now properly clears global filters from localStorage
-- Updated reset button click handler in `filters.js`
-- Added `localStorage.removeItem('filterScope')` and `localStorage.removeItem('globalFilters')`
-- Clears all filter-related localStorage keys
-- Reloads page with clean URL
-
-### 10. Database Indexes ✅
-**Completed:** Added indexes for filter columns to improve performance
-- Indexes created in `ensure_predefined_query_indexes()` function in `web/database.py`
-- Function called automatically on app startup in `web/main.py`
-- Indexes on: `playtime_hours`, `total_rating`, `added_at`, `release_date`, `nsfw`, `hidden`, `updated_at`, `aggregated_rating`, `total_rating_count`
-
-### 11. Integration Testing ✅
-**Completed:** Created comprehensive integration test suite
-- Added `tests/test_predefined_filters_integration.py` (26 integration tests)
-- Tests individual filters with expected SQL conditions
-- Tests filter combinations (2-3 active simultaneously)
-- Tests NULL value handling in date and rating filters
-- Tests empty result sets (no games match filters)
-- Tests conflicting filter combinations
-- Tests API endpoints with various filter combinations
-- **All 52 tests passing** (26 unit + 26 integration)
-
-### 12. Deprecation Warnings ✅
-**Completed:** Fixed all Python 3.12+ and Starlette deprecation warnings

-### Data Flow
-1. **Page Load:**
-   - Route provides filter context (store_counts, genre_counts, etc.)
-   - Template includes `_filter_bar.html`
-   - Page loads `filters.css` and `filters.js`
-   - `filters.js` initializes and checks for global filters in localStorage
-   - If global filters enabled, auto-apply filters on load

-## Context
-
-The library page currently supports filtering by stores, genres, and text search, plus sorting by various fields. These filters are applied as query parameters and produce SQL WHERE clauses dynamically. The UI displays filter tags that can be toggled on/off, with active filters persisting in the URL.
-
-This design extends the existing filter architecture to support predefined query filters - reusable SQL conditions mapped to user-friendly labels like "Unplayed" or "Highly Rated". The implementation should integrate seamlessly with existing filters without disrupting current behavior.
-
-**Current Architecture:**
-- `web/routes/library.py`: Handles `/library` route with `stores`, `genres`, `search`, `sort`, `order` parameters
-- `web/templates/index.html`: Displays filter UI with store/genre tag pills
-- JavaScript: Handles filter toggle and URL synchronization
-- Database: SQLite with games table containing all necessary fields
-
-**Constraints:**
-- Must work with existing SQLite queries (no ORM, raw SQL)
-- No database schema changes
-- Must integrate with existing filter UI patterns
-- Backend is FastAPI with Jinja2 templates
-
-## Goals / Non-Goals
-
-**Goals:**
-- Add 18 predefined query filters across 4 categories (gameplay, ratings, dates, content)
-- Support multi-select filter combinations
-- Maintain URL persistence for bookmarking/sharing
-- Show result counts for active filters
-- Integrate seamlessly with existing store/genre filters
-- Optimize query performance with appropriate indexes
-
-**Non-Goals:**
-- User-defined custom queries (future enhancement)
-- Saved filter presets/favorites
-- Filter recommendations/suggestions
-- Applying filters to other pages (Discover, Collections)
-- Advanced filter logic (AND/OR/NOT combinations beyond multi-select)
-- Filter analytics or usage tracking
-
-## Decisions
-
-### 1. Filter Definition Structure
-
-**Decision:** Define filters as a constant dictionary mapping filter IDs to SQL WHERE clause fragments.
-
-**Rationale:**
-- Keeps filter logic centralized and easy to modify
-- SQL fragments can be directly injected into existing query builder
-- Filter IDs serve as both URL parameters and internal references
-- Dictionary structure allows easy lookup and validation
-
-**Alternative Considered:**
-- Database-stored filter definitions: Rejected due to unnecessary complexity for static filters
-- Class-based filter objects: Rejected as overkill for simple WHERE clauses
-
-**Implementation:**
-```python
-# In web/routes/library.py or web/utils/filters.py
-PREDEFINED_QUERIES = {
-    # Gameplay
-    "unplayed": "(playtime_hours IS NULL OR playtime_hours = 0)",
-    "played": "playtime_hours > 0",
-    "started": "(playtime_hours > 0 AND playtime_hours < 5)",
-    "well-played": "playtime_hours >= 5",
-    "heavily-played": "playtime_hours >= 20",
-    
-    # Ratings
-    "highly-rated": "total_rating >= 90",
-    "well-rated": "total_rating >= 75",
-    "below-average": "(total_rating < 75 AND total_rating IS NOT NULL)",
-    "unrated": "total_rating IS NULL",
-    "hidden-gems": "(total_rating >= 75 AND total_rating < 90 AND aggregated_rating IS NULL)",
-    "critic-favorites": "aggregated_rating >= 80",
-    "community-favorites": "(igdb_rating >= 85 AND igdb_rating_count >= 100)",
-    
-    # Dates
-    "recently-added": "added_at >= DATE('now', '-30 days')",
-    "older-library": "added_at < DATE('now', '-6 months')",
-    "recent-releases": "release_date >= DATE('now', '-1 year')",
-    "recently-updated": "last_modified >= DATE('now', '-30 days')",
-    "classics": "(release_date <= DATE('now', '-10 years') AND total_rating >= 80)",
-    
-    # Content
-    "nsfw": "nsfw = 1",
-    "safe": "(nsfw = 0 OR nsfw IS NULL)"
-}
-
-# Display names for UI
-QUERY_DISPLAY_NAMES = {
-    "unplayed": "Unplayed",
-    "played": "Played",
-    "started": "Started",
-    "well-played": "Well Played",
-    "heavily-played": "Heavily Played",
-    "highly-rated": "Highly Rated",
-    "well-rated": "Well Rated",
-    "below-average": "Below Average",
-    "unrated": "Unrated",
-    "hidden-gems": "Hidden Gems",
-    "critic-favorites": "Critic Favorites",
-    "community-favorites": "Community Favorites",
-    "recently-added": "Recently Added",
-    "older-library": "Older Library",
-    "recent-releases": "Recent Releases",
-    "recently-updated": "Recently Updated",
-    "classics": "Classics",
-    "nsfw": "NSFW",
-    "safe": "Safe Content"
-}
-
-# Category grouping for UI organization
-QUERY_CATEGORIES = {
-    "Gameplay": ["unplayed", "played", "started", "well-played", "heavily-played"],
-    "Ratings": ["highly-rated", "well-rated", "below-average", "unrated", "hidden-gems", 
-                "critic-favorites", "community-favorites"],
-    "Dates": ["recently-added", "older-library", "recent-releases", "recently-updated", "classics"],
-    "Content": ["nsfw", "safe"]
-}
-```
-
-### 2. Backend Query Building
-
-**Decision:** Extend existing library route to accept `queries` parameter (list of filter IDs) and build combined WHERE clause.
-
-**Rationale:**
-- Minimal changes to existing code
-- FastAPI's `Query(default=[])` handles multi-value parameters naturally
-- SQL injection safe (filter clauses are hardcoded, not user input)
-- Easy to combine with existing filters using AND logic
-
-**Implementation:**
-```python
-@router.get("/library", response_class=HTMLResponse)
-def library(
-    request: Request,
-    stores: list[str] = Query(default=[]),
-    genres: list[str] = Query(default=[]),
-    queries: list[str] = Query(default=[]),  # NEW
-    search: str = "",
-    sort: str = "name",
-    order: str = "asc",
-    conn: sqlite3.Connection = Depends(get_db)
-):
-    # ... existing setup ...
-    
-    query = "SELECT * FROM games WHERE 1=1" + EXCLUDE_HIDDEN_FILTER
-    params = []
-    
-    # ... existing store/genre/search filters ...
-    
-    # NEW: Add predefined query filters
-    if queries:
-        valid_queries = [q for q in queries if q in PREDEFINED_QUERIES]
-        if valid_queries:
-            for query_id in valid_queries:
-                query += f" AND {PREDEFINED_QUERIES[query_id]}"
-    
-    # ... rest of existing logic ...
-```
-
-**Alternative Considered:**
-- Separate `/library/filtered` endpoint: Rejected to avoid code duplication
-- Query builder class: Over-engineering for this use case
-
-### 3. Frontend UI Integration
-
-**Decision:** Add a new filter section below existing store/genre filters, using same tag pill styling.
-
-**Rationale:**
-- Consistent with existing UI patterns
-- Users already familiar with multi-select tag behavior
-- Natural visual grouping by category
-- Minimal CSS changes needed
-
-**Implementation:**
-- Add filter section in `index.html` template
-- Use same `.filter-tag` CSS class as store/genre filters
-- Group filters by category with headers
-- Active filters highlighted with `.active` class
-- JavaScript toggles query parameters in URL
-
-**Layout:**
-```
-[Store Filters: Steam | Epic | GOG ...]
-[Genre Filters: Action | RPG | Adventure ...]
-[Quick Filters:
-  Gameplay: [Unplayed] [Played] [Started] ...
-  Ratings: [Highly Rated] [Well Rated] ...
-  Dates: [Recently Added] [Recent Releases] ...
-  Content: [Safe Content] [NSFW]
-]
-[Game Grid...]
-```
-
-### 4. URL Parameter Strategy
-
-**Decision:** Use repeated `queries=` parameters for multi-select (e.g., `?queries=unplayed&queries=highly-rated`).
-
-**Rationale:**
-- FastAPI handles this naturally with `list[str]`
-- Standard REST pattern for multi-value parameters
-- Works with existing URL state management
-- Easy to parse and manipulate in JavaScript
-
-**Alternative Considered:**
-- Comma-separated single parameter: Harder to manipulate in JS, encoding issues
-- JSON parameter: Overkill, poor URL readability
-
-### 5. Performance Optimization
-
-**Decision:** Add database indexes on frequently filtered columns if query performance degrades.
-
-**Rationale:**
-- SQLite benefits from indexes on WHERE clause columns
-- Indexes have minimal storage overhead
-- Can add incrementally based on actual performance data
-
-**Indexes to consider:**
-```sql
-CREATE INDEX IF NOT EXISTS idx_games_playtime ON games(playtime_hours);
-CREATE INDEX IF NOT EXISTS idx_games_total_rating ON games(total_rating);
-CREATE INDEX IF NOT EXISTS idx_games_added_at ON games(added_at);
-CREATE INDEX IF NOT EXISTS idx_games_release_date ON games(release_date);
-CREATE INDEX IF NOT EXISTS idx_games_nsfw ON games(nsfw);
-```
-
-**When to add:** Only if page load times exceed 500ms with typical filter combinations (measure first, optimize second).
-
-### 6. Filter Result Counts
-
-**Decision:** Show result counts only for currently active filters, not all possible filters.
-
-**Rationale:**
-- Showing counts for all 18 filters requires 18 additional COUNT queries
-- Performance impact too high for marginal UX benefit
-- Active filter counts provide sufficient feedback
-- Can add "preview counts" in future if needed with caching
-
-**Implementation:**
-- Display count in existing stats area: "Showing X games (Y total)"
-- Active filter pills show count in badge: "[Unplayed (42)]"
-
-## Risks / Trade-offs
-
-### 1. Query Performance with Multiple Filters
-**Risk:** Combining many filters could create slow queries, especially without proper indexes.
-
-**Mitigation:**
-- Add indexes on filtered columns
-- Monitor query execution time in development
-- Consider query plan analysis for complex combinations
-- Document recommended filter combinations
-
-### 2. Filter Conflict Logic
-**Risk:** Users might select conflicting filters (e.g., "Unplayed" + "Heavily Played").
-
-**Mitigation:**
-- Allow conflicting filters (results in empty set, which is valid)
-- Future: Add UI hints about inverse filters
-- Document behavior: filters use AND logic (all must match)
-
-### 3. Store-Specific Filters
-**Risk:** "Recently Updated" only works for Epic Games, may confuse users.
-
-**Mitigation:**
-- Document in UI tooltip or help text
-- Consider adding "(Epic only)" suffix to filter label
-- Future: Dynamically show/hide store-specific filters based on selected stores
-
-### 4. Mobile Responsiveness
-**Risk:** 18 filter tags may clutter mobile UI.
-
-**Mitigation:**
-- Use collapsible category sections on mobile
-- Show category count badges when collapsed
-- Test thoroughly on mobile devices
-
-### 5. Date Filter Accuracy
-**Risk:** Date-based filters like "Recent Releases" depend on accurate release_date data, which may be missing or incorrect.
-
-**Mitigation:**
-- Filters handle NULL dates gracefully (excluded from results)
-- Document that results depend on metadata quality
-- Consider adding "Unknown Release Date" filter option
-
-## Migration Plan
-
-### Deployment Steps
-
-1. **Backend changes** (non-breaking):
-   - Add filter constants to `web/utils/filters.py` or `web/routes/library.py`
-   - Update `library()` route to handle `queries` parameter
-   - Add optional indexes in database migration
-
-2. **Frontend changes** (non-breaking):
-   - Add filter UI section to `index.html` template
-   - Add JavaScript for filter toggle behavior
-   - Add minimal CSS for filter category grouping
-
-3. **Testing**:
-   - Test all filter combinations
-   - Verify URL persistence and bookmarking
-   - Test with various database states (missing data, NULL values)
-   - Check mobile responsiveness
-
-4. **Rollout**:
-   - Deploy to production (no downtime required)
-   - Monitor query performance
-   - Add indexes if needed based on metrics
-
-### Rollback Strategy
-
-Changes are additive and non-breaking:
-- Remove `queries` parameter handling from backend (old URLs still work)
-- Remove filter UI section from frontend
-- Keep database indexes (harmless if unused)
-
-No data migration or schema changes required, so rollback is straightforward.
-
-## Open Questions
-
-1. **Should we limit the number of active filters?**
-   - Current thinking: No limit, let users experiment
-   - Monitor for performance issues with many filters
-
-2. **Should filters be mutually exclusive within categories?**
-   - Current thinking: No, allow any combination
-   - Exception: Conflicting filters (e.g., "Unplayed" + "Played") produce empty results
-
-3. **Should we add "Clear All Filters" button?**
-   - Current thinking: Yes, add to filter section
-   - Should clear query filters only, or all filters including stores/genres?
-
-4. **Should filter state persist in browser localStorage?**
-   - Current thinking: URL persistence is sufficient for now
-   - localStorage could be added later for "remember my filters" feature
-
-5. **Should we show filter tooltips explaining criteria?**
-   - Current thinking: Yes, helpful for transparency
-   - Show SQL condition in tooltip for power users

-## Why
-
-Users currently have basic filtering capabilities (stores, genres, search) in the library view, but lack quick access to common queries like "unplayed games," "highly rated titles," or "recent releases." These queries require manual combination of sort/filter parameters and aren't easily reusable. Adding predefined query filters as toggleable tags would improve discoverability and reduce friction when browsing the library with specific intent.
-
-## What Changes
-
-Add a new filter section to the library page with predefined query tags that apply SQL-based filters to the games list. These filters will:
-
-- Appear alongside existing store and genre filters as clickable tags
-- Support multi-select (combine multiple predefined queries)
-- Apply database-level filtering using existing fields (playtime, ratings, dates)
-- Show result counts for each filter when applied
-- Persist in URL query parameters for bookmarking
-
-**New filter categories:**
-
-### Gameplay-based filters
-- **Unplayed**: `playtime_hours IS NULL OR playtime_hours = 0`
-- **Played**: `playtime_hours > 0` (inverse of Unplayed)
-- **Started**: `playtime_hours > 0 AND playtime_hours < 5`
-- **Well Played**: `playtime_hours >= 5`
-- **Heavily Played**: `playtime_hours >= 20`
-
-### Rating-based filters
-- **Highly Rated**: `total_rating >= 90`
-- **Well Rated**: `total_rating >= 75`
-- **Below Average**: `total_rating < 75 AND total_rating IS NOT NULL` (inverse of Well Rated)
-- **Unrated**: `total_rating IS NULL` (games without ratings)
-- **Hidden Gems**: `total_rating >= 75 AND total_rating < 90 AND aggregated_rating IS NULL`
-- **Critic Favorites**: `aggregated_rating >= 80`
-- **Community Favorites**: `igdb_rating >= 85 AND igdb_rating_count >= 100`
-
-### Date-based filters
-- **Recently Added**: `added_at >= DATE('now', '-30 days')`
-- **Older Library**: `added_at < DATE('now', '-6 months')` (inverse of Recently Added)
-- **Recent Releases**: `release_date >= DATE('now', '-1 year')`
-- **Recently Updated**: `last_modified >= DATE('now', '-30 days')` (Epic only)
-- **Classics**: `release_date <= DATE('now', '-10 years') AND total_rating >= 80`
-
-### Content filters
-- **NSFW Content**: `nsfw = 1`
-- **Safe Content**: `nsfw = 0 OR nsfw IS NULL` (inverse of NSFW)
-
-## Capabilities
-
-### New Capabilities
-
-- `predefined-query-filters`: Backend logic and UI components for applying predefined SQL filters to the library view, including multi-select support, result counting, and URL persistence
-
-### Modified Capabilities
-
-None - this extends existing library filtering without changing current filter behavior.
-
-## Impact
-
-### Affected Code
-- **web/routes/library.py**: Add query parameter parsing and SQL filter building for predefined queries
-- **web/templates/index.html**: Add new filter section UI with predefined query tags
-- **web/static/js/**: Add JavaScript for toggle behavior and URL state management
-
-### Database
-- No schema changes required - uses existing fields
-- Query performance may need optimization for complex filter combinations (consider indexes on `playtime_hours`, `total_rating`, `added_at`, `release_date`)
-
-### UI/UX
-- New filter section added above game grid
-- Filter tags use same visual style as genre/store filters
-- Active filters show result counts
-- Clear visual feedback when filters are applied
-
-### Store Integrations
-- No changes to store sync logic
-- "Recently Updated" filter only applies to Epic Games (other stores will show no results for this filter)
-- Filter availability could be store-aware in future iterations
-
-### Non-goals
-- **Not** adding custom user-defined queries (future enhancement)
-- **Not** modifying existing filter/sort behavior
-- **Not** adding new database fields or columns
-- **Not** creating saved filter presets (future enhancement)
-- **Not** applying predefined queries to other pages (Discover, Collections)
-
-## Implementation Approach
-
-1. **Backend**: Extend library route to accept `queries` parameter (list of filter IDs), map to SQL WHERE clauses
-2. **Frontend**: Add filter tag section, implement multi-select toggle behavior with URL state sync
-3. **UI Design**: Follow existing filter styling (store/genre tags) for consistency
-4. **Performance**: Add database indexes if query performance degrades with complex filters
-5. **Testing**: Verify filter combinations work correctly, test URL persistence and bookmarking

-## ADDED Requirements
-
-### Requirement: Predefined filter definitions
-The system SHALL provide 18 predefined query filters organized into 4 categories (Gameplay, Ratings, Dates, Content). Each filter SHALL map to a specific SQL WHERE clause condition that filters games based on existing database fields.
-
-#### Scenario: Filter definitions are available
-- **WHEN** the library route initializes
-- **THEN** all 18 predefined filters SHALL be defined with their SQL conditions and display names
-
-#### Scenario: Filters are organized by category
-- **WHEN** filters are rendered in the UI
-- **THEN** filters SHALL be grouped into 4 categories: Gameplay (5 filters), Ratings (7 filters), Dates (5 filters), and Content (2 filters)
-
-### Requirement: Query parameter handling
-The system SHALL accept a `queries` parameter in the library route that contains a list of filter IDs. The route SHALL validate filter IDs against the predefined filter definitions.
-
-#### Scenario: Single filter parameter
-- **WHEN** user navigates to `/library?queries=unplayed`
-- **THEN** system SHALL apply the "Unplayed" filter condition to the games query
-
-#### Scenario: Multiple filter parameters
-- **WHEN** user navigates to `/library?queries=unplayed&queries=highly-rated`
-- **THEN** system SHALL apply both filter conditions using AND logic
-
-#### Scenario: Invalid filter ID
-- **WHEN** user provides an invalid filter ID in the queries parameter
-- **THEN** system SHALL ignore the invalid filter ID and continue processing valid filters
-
-#### Scenario: Empty queries parameter
-- **WHEN** queries parameter is empty or not provided
-- **THEN** system SHALL apply no predefined filters and show all games based on other filters
-
-### Requirement: SQL filter application
-The system SHALL build SQL WHERE clauses by combining predefined filter conditions with existing filters (stores, genres, search). All filters SHALL be combined using AND logic.
-
-#### Scenario: Filter with existing store filter
-- **WHEN** user applies queries=unplayed with stores=steam
-- **THEN** system SHALL return only Steam games that are unplayed
-
-#### Scenario: Filter with existing genre filter
-- **WHEN** user applies queries=highly-rated with genres=Action
-- **THEN** system SHALL return only Action games with rating >= 90
-
-#### Scenario: Multiple predefined filters combined
-- **WHEN** user applies queries=unplayed&queries=well-rated
-- **THEN** system SHALL return games where (playtime_hours IS NULL OR playtime_hours = 0) AND total_rating >= 75
-

Subject: [PATCH 06/30] bug: corrected prefixing of columns in the SQL queries
 (and added a test case) Based on this review: > SQL errors on collection
 detail page The .replace() chain in collections.py for prefixing column names
 with g. only covers 5 columns (playtime_hours, total_rating, added_at,
 release_date, nsfw). Filters like "community-favorites" (igdb_rating,
 igdb_rating_count), "critic-favorites" (aggregated_rating), and
 "recently-updated" (last_modified) will throw SQL errors when used on
 collection pages.

params.append(f'%"{genre.lower()}%')

Should be:

params.append(f'%"{genre.lower()}"%')

Without the closing ", the pattern %"action% could match unintended substrings.

 exception handling less bare Based on these reviews:
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

> Bare except: clauses
In collections.py and discover.py, the genre parsing uses bare except: which swallows all exceptions including KeyboardInterrupt and SystemExit. Please use except Exception: at minimum, or better yet except (json.JSONDecodeError, TypeError):.

> import json inside a loop
In collections.py, import json is inside the genre-parsing loop — should be at the top of the file.

Subject: [PATCH 12/30] fix: reverted auto-refresh when selecting filters (and
 added an Apply button) ; also, changed the filters logic (see
 filter-system.md) to combine filters with  ORs in the same category and with
 ANDs between categories.

Based on this review:
> Auto-apply conflicts with Apply button
The store/genre dropdowns have explicit "Apply" buttons, but filters.js also auto-applies after a 300ms debounce on checkbox changes. Users could get redirected before they finish selecting multiple options. I'd suggest picking one approach — either auto-apply (and remove the button) or manual apply (and remove the debounce).

 The predefined query filters system provides a flexible, reusable filtering mechanism for games across the Backlogia application. It enables users to filter their library, collections, and discovery pages using 18 predefined filters organized into 4 categories.
 
+**Key Feature:** Filters within the same category are combined with **OR** logic, while filters from different categories are combined with **AND** logic. This allows intuitive multi-selection within categories (e.g., "show played OR started games") while maintaining strict requirements across categories (e.g., "AND highly-rated").

 **Categories:**
-- `status`: Game completion and play status (8 filters)
-- `metadata`: Games with/without external metadata (4 filters)
-- `playtime`: Playtime-based filters (4 filters)
-- `release`: Release date filters (2 filters)
+- `Gameplay`: Game completion and play status (8 filters: unplayed, played, started, well-played, heavily-played, completed, abandoned, incomplete)
+- `Ratings`: Rating-based filters (7 filters: highly-rated, well-rated, critic-favorites, community-favorites, hidden-gems, below-average, unrated)
+- `Dates`: Time-based filters (5 filters: recently-added, old-games, recently-updated, new-releases, classics)
+- `Content`: Content classification (2 filters: nsfw, safe)
 
 **Key Design Principles:**
 - Each filter has a unique ID (kebab-case)
 - SQL conditions are parameterized and injectable
-- Filters can be combined with AND logic
+- **Filters within the same category are combined with OR logic**
+- **Filters from different categories are combined with AND logic**
 - All filters respect store and genre selections

+**Function:** `build_query_filter_sql(query_ids: list[str], table_prefix: str = "") -> str`
 
-Converts filter IDs into SQL WHERE conditions.
+Converts filter IDs into SQL WHERE conditions with intelligent OR/AND logic.
 
 **Logic:**
-- Retrieves SQL query for each valid filter ID
-- Combines multiple filters with `AND`
-- Returns empty string if no valid filters
-- Each condition is wrapped in parentheses for safety
+1. Groups filters by category
+2. Within each category: combines filters with **OR**
+3. Between categories: combines groups with **AND**
+4. Applies optional table prefix for JOIN queries (e.g., `g.` for collections)
+5. Returns empty string if no valid filters
+
+**Examples:**
+
+*Single filter:*
+```python
+build_query_filter_sql(["played"])
+# Returns: "(playtime_hours > 0)"
+```
+
+*Multiple filters, same category (OR):*
+```python
+build_query_filter_sql(["played", "started"])
+# Returns: "((playtime_hours > 0) OR (playtime_hours > 0 AND playtime_hours < 5))"
+# Meaning: Show games that are played OR started
+```
+
+*Multiple filters, different categories (AND):*
+```python
+build_query_filter_sql(["played", "highly-rated"])
+# Returns: "((playtime_hours > 0) AND (total_rating >= 90))"
+# Meaning: Show games that are played AND highly-rated
+```
 
-**Example:**
+*Complex combination (OR within, AND between):*
 ```python
-build_predefined_filter_sql(["unplayed", "backlog"])
-# Returns: "(playtime_seconds = 0) AND (tags LIKE '%backlog%')"
+build_query_filter_sql(["played", "started", "highly-rated", "well-rated"])
+# Returns: "(((playtime_hours > 0) OR (playtime_hours > 0 AND playtime_hours < 5)) AND ((total_rating >= 90) OR (total_rating >= 75)))"
+# Meaning: Show games that are (played OR started) AND (highly-rated OR well-rated)
 ```
 
+*With table prefix for JOIN queries:*
+```python
+build_query_filter_sql(["played"], table_prefix="g.")
+# Returns: "(g.playtime_hours > 0)"
+# Used in collection queries where games table is aliased as 'g'
+```
+
+**Why OR/AND Logic?**
+
+This approach enables intuitive filter combinations:
+- **Same category OR**: Select multiple gameplay states (e.g., "played OR started") without excluding all results
+- **Different categories AND**: Maintain strict requirements across different aspects (e.g., "must be played AND must be highly-rated")
+
+Without this logic, selecting "played" + "started" would return zero results (impossible for a game to be both), making multi-selection within categories useless.
+
+### Filter Combination Logic
+
+#### How Filters Are Combined
+
+The system uses a two-level combination strategy:
+
+1. **Within Categories (OR Logic)**
+   - Filters in the same category are alternatives
+   - Results match ANY selected filter from that category
+   - Example: `[played OR started]` = games matching either condition
+
+2. **Between Categories (AND Logic)**
+   - Each category's result set must be satisfied
+   - Results match ALL category requirements
+   - Example: `[Gameplay filters] AND [Rating filters]` = games matching both groups
+
+#### Practical Examples
+
+**Example 1: Multiple Gameplay Filters**
+```
+Selected: "played", "started" (both from Gameplay category)
+SQL: ((playtime_hours > 0) OR (playtime_hours > 0 AND playtime_hours < 5))
+Result: Games that are played OR started
+```
+
+**Example 2: Multiple Rating Filters**
+```
+Selected: "highly-rated", "well-rated" (both from Ratings category)
+SQL: ((total_rating >= 90) OR (total_rating >= 75))
+Result: Games that are highly-rated OR well-rated
+```
+
+**Example 3: Cross-Category Selection**
+```
+Selected: "played" (Gameplay), "highly-rated" (Ratings)
+SQL: ((playtime_hours > 0) AND (total_rating >= 90))
+Result: Games that are played AND highly-rated
+```
+
+**Example 4: Complex Multi-Category**
+```
+Selected: "played", "started" (Gameplay), "highly-rated", "well-rated" (Ratings), "recently-added" (Dates)
+SQL: (
+    ((playtime_hours > 0) OR (playtime_hours > 0 AND playtime_hours < 5))
+    AND
+    ((total_rating >= 90) OR (total_rating >= 75))
+    AND
+    (added_at >= DATE('now', '-30 days'))
+)
+Result: Games that are (played OR started) AND (highly OR well rated) AND recently added
+```

+#### Category Reference
+
+| Category | Filters | Combination |
+|----------|---------|-------------|
+| **Gameplay** | unplayed, played, started, well-played, heavily-played, completed, abandoned, incomplete | OR |
+| **Ratings** | highly-rated, well-rated, critic-favorites, community-favorites, hidden-gems, below-average, unrated | OR |
+| **Dates** | recently-added, old-games, recently-updated, new-releases, classics | OR |
+| **Content** | nsfw, safe | OR |
+| **Between Categories** | Any mix of categories | AND |
+
+#### Implementation Details
+
+The `build_query_filter_sql()` function implements this logic by:
+
+1. **Grouping**: Iterates through selected filters and groups them by category using `QUERY_CATEGORIES` mapping
+2. **Within-Category**: For each category with multiple filters, wraps them in `(filter1 OR filter2 OR ...)`
+3. **Between-Category**: Wraps each category group and joins with AND: `(category1_group) AND (category2_group) AND ...`
+4. **Parenthesization**: All conditions are properly parenthesized to avoid operator precedence issues
+5. **Table Prefixing**: Optionally prefixes column names (e.g., `g.playtime_hours`) for JOIN queries in collections

+**Code Location:** `web/utils/filters.py::build_query_filter_sql()`

+1. **Define in `PREDEFINED_QUERIES` (`web/utils/filters.py`):**
+```python
+"new-filter": "SQL WHERE condition (e.g., playtime_hours >= 100)"

+2. **Add to `QUERY_DISPLAY_NAMES`:**
 ```python
-"new-filter": {
-    "label": "Display Name",
-    "description": "What this filter does",
-    "query": "SQL WHERE condition",
-    "category": "existing_category"
+"new-filter": "Display Name"
+```
+
+3. **Add to `QUERY_DESCRIPTIONS`:**
+```python
+"new-filter": "Description of what this filter does"
+```
+
+4. **Add to appropriate category in `QUERY_CATEGORIES`:**
+```python
+QUERY_CATEGORIES = {
+    "Gameplay": [..., "new-filter"],  # Choose appropriate category
+    # ...
 }
 ```
 
-2. **Create database index (if needed):**
+**Important:** The category you choose determines how this filter combines with others:
+- Filters in the same category will use OR logic
+- Filters in different categories will use AND logic
+

-
-Template will automatically pick up new filter from `PREDEFINED_QUERIES`.
-
-4. **Write tests:**
+6. **Write tests:**
 ```python
+def test_new_filter_logic():
+    """Test new filter SQL generation"""
+    result = build_query_filter_sql(["new-filter"])
+    assert "expected SQL condition" in result
+
 def test_new_filter_integration(client):

+    """Test new filter in HTTP request"""
+    response = client.get("/library?queries=new-filter")
     # Verify results match expected SQL condition
 ```
 
 ### Adding a New Category
 
-1. **Update `PREDEFINED_QUERIES`:**
-
-Add filters with `"category": "new_category"`
-
-2. **Update filter bar template:**
-
-Add new section in `_filter_bar.html`:
-```html
-<div class="filter-section">
-    <button class="filter-dropdown-toggle" aria-label="Category Name">
-        Category Name
-    </button>
-    <div class="filter-options" role="group">
-        {% for filter_id, filter_data in predefined_queries.items() %}
-            {% if filter_data.category == 'new_category' %}
-                <!-- Filter checkbox -->
-            {% endif %}
-        {% endfor %}
-    </div>
-</div>
+1. **Add to `QUERY_CATEGORIES` (`web/utils/filters.py`):**
+```python
+QUERY_CATEGORIES = {
+    "Gameplay": [...],
+    "Ratings": [...],
+    "Dates": [...],
+    "Content": [...],
+    "New Category": ["filter1", "filter2"],  # New category
+}
 ```
 
-3. **Update JavaScript (if interactive):**
+2. **Update filter bar template (`web/templates/_filter_bar.html`):**
+
+The template automatically renders categories from `QUERY_CATEGORIES`, so no changes needed unless you want custom styling.
+
+3. **Consider logical grouping:**
+
+Remember that filters within your new category will combine with OR, while combinations with other categories will use AND. Choose filters that make sense as alternatives (e.g., different playtime ranges, different rating thresholds).
+
+**Example Use Case:**
 
-Add dropdown toggle handler in `filters.js`.
+If you create a "Multiplayer" category with filters like "has-multiplayer", "co-op-only", "pvp-only", selecting multiple would show games matching ANY of those (OR logic), while combining with other categories would require games to match both multiplayer criteria AND other requirements.
+
+### Testing Filter Combinations
+
+When adding new filters or categories, test the OR/AND logic:
+
+```python
+def test_new_filter_same_category_or():
+    """Test new filters in same category use OR"""
+    result = build_query_filter_sql(["filter1", "filter2"])  # Same category
+    assert " OR " in result
+    assert result.count("(") == result.count(")")  # Balanced parentheses
+
+def test_new_filter_cross_category_and():
+    """Test new filter with existing category uses AND"""
+    result = build_query_filter_sql(["new-filter", "played"])  # Different categories
+    assert " AND " in result
+    assert " OR " not in result or result.count(" AND ") > 0
+```

Subject: [PATCH 13/30] fix: updated filters.css to handle responsive design on
 mobile phones.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Based on this review:
> Mobile regression
The old index.html had mobile-specific styles transforming dropdowns into bottom sheets. The new filters.css responsive section only does flex-direction: column — the bottom-sheet behavior appears to be lost. Could you verify the filter bar works well on mobile?

 .games-grid CSS rule
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Based on these reviews:

> query_filter_counts is always {} for discover, collection detail, and random pages — the Quick Filters dropdown won't show counts on those pages (intentional?)

> Dead .games-grid CSS rule with flex properties in index.html (overridden by the grid definition later — looks like a copy-paste artifact)

Subject: [PATCH 15/30] fix: restore /random endpoint to single-game redirect
 with global filters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Changes the /random endpoint to redirect to a single random game (instead of
showing a grid of 12 games), while applying global filters before selection.

Changes:
- Modified /random route to apply filters then redirect to one game
- Added filters.js to all pages with Random links to ensure filter persistence
- Removed random.html template and shared-game-cards.css (no longer needed)
- Updated documentation to reflect new behavior

This addresses PR review feedback requesting the original "surprise me with
one game" behavior while maintaining global filter support.

> /random endpoint behavior change
This currently redirects to a single random game detail page. The PR changes it to render a full grid of 12 games. I'd like to discuss this — I'm not sure I want to lose the "surprise me with one game" behavior. Could we keep the old redirect as the default and add the grid as a separate route (e.g. /random?grid=true) or a different path?

+### Random Game with Filters
+
+The `/random` endpoint applies global filters before selecting a game:
+
+**Behavior:**
+- Reads global filters from URL parameters (stores, genres, queries)
+- Applies filters to the games database query
+- Selects one random game from the filtered results
+- Redirects to that game's detail page
+- Returns 404 if no games match the selected filters
+
+**JavaScript Integration:**
+- `filters.js` intercepts Random link clicks on all pages
+- Automatically appends global filters from localStorage to the `/random` URL
+- Ensures filters persist across navigation, including on pages without filter bars (e.g., game detail pages)
+
+**User Experience:**
+- Clicking "Random" multiple times shows different games that match your filters
+- Filters are applied consistently across all pages via localStorage
+- If you change filters and click Random, the new filters are immediately applied

Subject: [PATCH 18/30] feat: implement labels system with priority and
 personal ratings

Phase 1 & 2: Backend implementation for unified labels system

- Migrate collections to labels with new fields (type, color, icon, system)
- Add priority (high/medium/low) and personal_rating (0-10) columns to games
- Create system_labels service with 5 auto playtime tags
- Add API endpoints for priority and personal rating (single + bulk)
- Add manual playtime tag endpoint for non-Steam games
- Update delete endpoints to use game_labels instead of collection_games

Subject: [PATCH 19/30] feat: add priority and rating UI to bulk actions

Phase 3 (partial): Frontend UI for priority and personal rating

- Add Priority and Personal Rating buttons to floating action bar
- Add dropdown menus for selecting priority (high/medium/low) and rating (0-10)
- Add JavaScript functions for bulk operations (bulkSetPriority, bulkSetPersonalRating)
- Add CSS styling for new buttons and dropdown menus
- Auto-close dropdowns when clicking outside

Next: Add badges display on game cards, update filters, add sync hooks

Subject: [PATCH 20/30] feat: add priority and rating badges on game cards

Added visual badges on game cards to display:
- Priority indicators (high/medium/low) with colored circles
- Personal rating badges with star icons and numeric value

Badges are positioned in top-left corner of card covers with:
- Backdrop blur for readability
- Responsive sizing for different grid sizes
- Proper z-index layering above cover images

Subject: [PATCH 21/30] fix: update collections routes to use labels tables

Migrated all collections endpoints to use the new unified labels system:
- Changed table references from collections/collection_games to labels/game_labels
- Added type='collection' filters to all queries
- Updated column references (c.* to l.*, cg.* to gl.*)
- Maintained all existing API endpoints and functionality

Subject: [PATCH 22/30] feat: add manual playtime tag UI for bulk operations

Added "Playtime Tag" button to action bar with dropdown menu:
- 5 manual playtime tags: never-launched, just-tried, played, well-played, heavily-played

Subject: [PATCH 26/30] feat: replace alert dialogs with toast notifications

- Added toast notification system with slide-in animations
- Toasts appear in top-right corner without interrupting workflow
- Success (green), error (red), and info (blue) variants
- Auto-dismiss after 3 seconds or click to close manually
- Replaced all alert() calls with showToast()
- More elegant and less disruptive UX

+### Automatic Gameplay Tagging (Steam)
+
+Steam games are automatically tagged with gameplay labels based on your playtime. Every time you sync your Steam library, Backlogia evaluates each game's playtime and assigns the appropriate label:
+
+| Label | Playtime |
+|-------|----------|
+| **Never Launched** | 0 hours |
+| **Just Tried** | < 2 hours |
+| **Played** | 2 - 10 hours |
+| **Well Played** | 10 - 50 hours |
+| **Heavily Played** | 50+ hours |
+
+- Labels update automatically on each Steam sync — no manual action required
+- Labels are visible on game detail pages and power the Gameplay filters above
+- Steam-only: other stores don't provide reliable playtime data, but you can assign labels manually
+- See [System Labels documentation](docs/system-labels-auto-tagging.md) for technical details
+
 ### Rich Game Details
 
 Every game is enriched with metadata from IGDB (Internet Game Database), giving you consistent information across all stores.

+## Single Game Operations
+
+### Set Game Priority
+
+Set or clear the priority level for a game.
+
+**Endpoint:** `POST /api/game/{game_id}/priority`
+
+**Request Body:**
+```json
+{
+  "priority": "high"
+}
+```
+
+**Valid Priority Values:**
+- `"high"` - High priority (red badge)
+- `"medium"` - Medium priority (amber badge)
+- `"low"` - Low priority (green badge)
+- `null` - Clear priority
+
+**Response (200 OK):**
+```json
+{
+  "success": true,
+  "priority": "high"
+}
+```

+curl -X POST http://localhost:5050/api/game/123/priority \
+  -H "Content-Type: application/json" \
+  -d '{"priority": "high"}'
+```
+
+**Error Responses:**
+- `400 Bad Request` - Invalid priority value (must be 'high', 'medium', 'low', or null)
+- `404 Not Found` - Game not found
+
+---
+
+### Set Personal Rating
+
+Set or clear the personal rating (0-10) for a game.
+
+**Endpoint:** `POST /api/game/{game_id}/personal-rating`
+
+**Request Body:**
+```json
+{
+  "rating": 8
+}
+```
+
+**Valid Rating Values:**
+- `0` - Remove rating (sets to NULL)

+  -d '{"rating": 8}'
+```
+
+**Remove Rating:**
+```bash
+curl -X POST http://localhost:5050/api/game/123/personal-rating \
+  -H "Content-Type: application/json" \
+  -d '{"rating": 0}'
+```
+
+**Error Responses:**
+- `400 Bad Request` - Rating out of range (must be 0-10)
+- `404 Not Found` - Game not found
+
+---
+
+### Set Manual Playtime Tag
+
+Manually assign a playtime tag to override auto-tagging or tag non-Steam games.
+
+**Endpoint:** `POST /api/game/{game_id}/manual-playtime-tag`
+
+**Request Body:**
+```json
+{
+  "label_name": "Well Played"
+}
+```
+
+**Valid Label Names:**
+- `"Never Launched"`
+- `"Just Tried"`

+
+---
+
+## Error Codes
+
+### 400 Bad Request
+
+**Causes:**
+- Invalid priority value (not 'high', 'medium', 'low', or null)
+- Rating out of range (not 0-10)
+- Empty game_ids array in bulk operations
+
+**Example Response:**
+```json
+{
+  "detail": "Priority must be 'high', 'medium', 'low', or null"
+}
+```
+
+### 404 Not Found
+
+**Causes:**
+- Game ID does not exist
+- Label/Collection ID does not exist

+## Notes for Developers
+
+### Request Validation
+
+All endpoints use Pydantic models for request validation:
+
+```python
+class UpdatePriorityRequest(BaseModel):
+    priority: Optional[str] = None  # 'high', 'medium', 'low', or None
+
+class UpdatePersonalRatingRequest(BaseModel):
+    rating: int  # 0-10
+
+class ManualPlaytimeTagRequest(BaseModel):
+    label_name: Optional[str] = None
+
+class BulkGameIdsRequest(BaseModel):
+    game_ids: list[int]
+```
+
+### Database Transactions
+
+- All bulk operations run in a single transaction
+- Single-game operations commit immediately
+- Failed operations trigger rollback
+
+### Performance Considerations
+
+- Bulk operations use parameterized queries with placeholders for efficiency
+- `INSERT OR IGNORE` prevents duplicate entries without checking first
+- Indexes on `game_labels.game_id` and `game_labels.label_id` optimize queries
+
+### Testing
+
+See [test_api_metadata_endpoints.py](../tests/test_api_metadata_endpoints.py) for comprehensive integration tests covering all endpoints.

+
+## Understanding the `auto` Column
+
+The `auto` column in `game_labels` is the cornerstone of the system's flexibility.
+
+### Lifecycle of an Auto Tag
+
+```
+1. Steam Sync
+   │
+   ▼
+2. Game has playtime_hours = 25.0
+   │
+   ▼
+3. update_auto_labels_for_game(conn, game_id)
+   │
+   ├─► DELETE FROM game_labels WHERE game_id = ? AND auto = 1
+   │   (Removes old auto tags, preserves manual tags with auto = 0)
+   │
+   ├─► Evaluate playtime against SYSTEM_LABELS conditions
+   │   → 25h matches "Well Played" (10 ≤ playtime < 50)
+   │
+   └─► INSERT INTO game_labels (label_id, game_id, auto)
+       VALUES (label_id_of_well_played, game_id, 1)
+   
+   Result: Game now has "Well Played" tag with auto = 1
+```
+
+### Manual Tag Override
+
+```
+User Action: Manually set "Just Tried" tag on game with 25h
+   │
+   ▼
+1. DELETE FROM game_labels WHERE game_id = ? AND label_id IN (system_labels)
+   (Removes ALL playtime tags, both auto and manual)
+   │
+   ▼
+2. INSERT INTO game_labels (label_id, game_id, auto)
+   VALUES (label_id_of_just_tried, game_id, 0)
+   │
+   ▼
+Result: Game has "Just Tried" tag with auto = 0
+
+Next Steam Sync:
+   │
+   ▼
+update_auto_labels_for_game(conn, game_id)
+   │
+   ├─► DELETE FROM game_labels WHERE game_id = ? AND auto = 1
+   │   (Query finds no rows to delete, manual tag has auto = 0)
+   │
+   └─► Skip INSERT because game is not steam or has existing manual tag
+       (Logic checks for existing system tags before inserting)
+
+Result: Manual "Just Tried" tag persists!
+```
+
+### Key Insight
+
+**Manual tags survive because:**
+1. DELETE query filters by `auto = 1` (only removes auto tags)
+2. INSERT logic checks if a system tag already exists before adding
+3. Manual tags block auto-tagging for that game
+
+---
+
+## Adding a New System Label
+
+Let's add a hypothetical "Marathon" label for games with 200+ hours.
+
+### Step 1: Update `SYSTEM_LABELS` Dictionary
+
+**File:** `web/services/system_labels.py`
+
+```python
+SYSTEM_LABELS = {
+    # ... existing labels ...
+    "heavily-played": {
+        "name": "Heavily Played",
+        "icon": "🏆",
+        "color": "#10b981",
+        "condition": lambda game: game["playtime_hours"] is not None and 50 <= game["playtime_hours"] < 200  # Changed upper bound
+    },
+    "marathon": {  # NEW LABEL
+        "name": "Marathon",
+        "icon": "🔥",
+        "color": "#dc2626",  # Red color for extreme playtime
+        "condition": lambda game: game["playtime_hours"] is not None and game["playtime_hours"] >= 200
+    }
+}
+```
+
+**Important:** Adjust boundaries of existing labels to avoid overlaps (e.g., "Heavily Played" now stops at 200h).
+
+### Step 2: Run Ensure System Labels
+
+On next app startup, `ensure_system_labels(conn)` will automatically:
+1. Detect new label in `SYSTEM_LABELS`
+2. Insert into database with `system = 1`
+
+No manual database migration needed!
+
+### Step 3: Update Filter Definitions
+
+**File:** `web/utils/filters.py`
+
+Add a new filter to the "Gameplay" category:
+
+```python
+PREDEFINED_FILTERS = {
+    # ... existing filters ...
+    "marathon": {
+        "name": "Marathon",
+        "category": "Gameplay",
+        "sql": _TAG_EXISTS.format(tag_name='Marathon'),
+        "description": "Games played for 200+ hours"
+    }
+}
+```
+
+### Step 4: Update Frontend (Optional)
+
+**File:** `web/templates/game_detail.html`
+
+Add "Marathon" to the playtime tag dropdown:
+
+```html
+<select id="playtimeTagSelect-{{ game.id }}">
+    <option value="">Remove Tag</option>
+    <option value="Never Launched">🎮 Never Launched</option>
+    <option value="Just Tried">👀 Just Tried</option>
+    <option value="Played">🎯 Played</option>
+    <option value="Well Played">⭐ Well Played</option>
+    <option value="Heavily Played">🏆 Heavily Played</option>
+    <option value="Marathon">🔥 Marathon</option>  <!-- NEW -->
+</select>
+```
+
+### Step 5: Add Tests
+
+**File:** `tests/test_system_labels_auto_tagging.py`
+
+```python
+def test_update_auto_labels_marathon(test_db_with_labels):
+    """Test 200+ hours gets Marathon label"""
+    cursor = test_db_with_labels.cursor()
+    
+    cursor.execute("INSERT INTO games (name, store, playtime_hours) VALUES (?, ?, ?)",
+                  ("Marathon Game", "steam", 250.0))
+    game_id = cursor.lastrowid
+    test_db_with_labels.commit()
+
+    update_auto_labels_for_game(test_db_with_labels, game_id)
+
+    cursor.execute("""
+        SELECT l.name FROM labels l
+        JOIN game_labels gl ON l.id = gl.label_id
+        WHERE gl.game_id = ? AND gl.auto = 1
+    """, (game_id,))
+    
+    labels = [row[0] for row in cursor.fetchall()]
+    assert labels == ['Marathon']
+
+
+def test_boundary_heavily_played_marathon(test_db_with_labels):
+    """Test boundary between Heavily Played and Marathon"""
+    cursor = test_db_with_labels.cursor()
+    
+    # Just under Marathon threshold
+    cursor.execute("INSERT INTO games (name, store, playtime_hours) VALUES (?, ?, ?)",
+                  ("Just Below", "steam", 199.9))
+    game_id_below = cursor.lastrowid
+    
+    # Exactly at Marathon threshold
+    cursor.execute("INSERT INTO games (name, store, playtime_hours) VALUES (?, ?, ?)",
+                  ("Exactly 200", "steam", 200.0))
+    game_id_exact = cursor.lastrowid
+    test_db_with_labels.commit()
+
+    update_auto_labels_for_game(test_db_with_labels, game_id_below)
+    update_auto_labels_for_game(test_db_with_labels, game_id_exact)
+
+    # Verify 199.9h gets Heavily Played
+    cursor.execute("""
+        SELECT l.name FROM labels l
+        JOIN game_labels gl ON l.id = gl.label_id
+        WHERE gl.game_id = ?
+    """, (game_id_below,))
+    assert cursor.fetchone()[0] == 'Heavily Played'
+
+    # Verify 200h gets Marathon
+    cursor.execute("""
+        SELECT l.name FROM labels l
+        JOIN game_labels gl ON l.id = gl.label_id
+        WHERE gl.game_id = ?
+    """, (game_id_exact,))
+    assert cursor.fetchone()[0] == 'Marathon'
+```
+
+### Step 6: Update Documentation
+
+Add "Marathon" to the table in [docs/system-labels-auto-tagging.md](system-labels-auto-tagging.md#gameplay-tags-system-labels):
+
+```markdown
+| **Marathon** | :fire: | `#dc2626` (red) | >= 200h | `playtime_hours >= 200` |
+```
+
+### Step 7: Trigger Re-tagging
+
+After deploying, run:
+
+```bash
+curl -X POST http://localhost:5050/api/labels/update-system-tags
+```
+
+This re-evaluates all games against the new boundaries.
+
+---
+
+## Adding a New Metadata Field
+
+Let's add a hypothetical "completion_status" field (e.g., "not_started", "in_progress", "completed", "abandoned").
+
+### Step 1: Add Database Column
+
+**File:** `web/database.py`
+
+Create a new migration function:
+
+```python
+def ensure_completion_status_column():
+    """Add completion_status column to games table."""
+    conn = sqlite3.connect(DATABASE_PATH)
+    cursor = conn.cursor()
+
+    # Check if games table exists
+    cursor.execute("SELECT name FROM sqlite_master WHERE type='table' AND name='games'")
+    if not cursor.fetchone():
+        conn.close()
+        return
+
+    # Check if column exists
+    cursor.execute("PRAGMA table_info(games)")
+    columns = {row[1] for row in cursor.fetchall()}
+
+    if "completion_status" not in columns:
+        cursor.execute("""
+            ALTER TABLE games ADD COLUMN completion_status TEXT
+            CHECK(completion_status IN ('not_started', 'in_progress', 'completed', 'abandoned', NULL))
+        """)
+        print("[OK] Added completion_status column to games table")
+
+    conn.commit()
+    conn.close()
+```
+
+**Important:** Use a CHECK constraint to enforce valid values at the database level.
+
+### Step 2: Call Migration at Startup
+
+**File:** `web/main.py`
+
+```python

+    ensure_labels_tables()
+    ensure_game_metadata_columns()
+    ensure_completion_status_column()  # NEW
+    # ...
+```
+
+### Step 3: Add API Endpoint
+
+**File:** `web/routes/api_metadata.py`
+
+```python
+class UpdateCompletionStatusRequest(BaseModel):
+    status: Optional[str] = None  # 'not_started', 'in_progress', 'completed', 'abandoned', or None
+
+
+@router.post("/api/game/{game_id}/completion-status")
+def set_game_completion_status(game_id: int, body: UpdateCompletionStatusRequest, conn: sqlite3.Connection = Depends(get_db)):
+    """Set completion status for a game."""
+    status = body.status
+
+    # Validate status value
+    valid_statuses = ('not_started', 'in_progress', 'completed', 'abandoned')
+    if status is not None and status not in valid_statuses:
+        raise HTTPException(status_code=400, detail=f"Status must be one of {valid_statuses} or null")

+    cursor.execute("UPDATE games SET completion_status = ? WHERE id = ?", (status, game_id))
+    conn.commit()
+
+    return {"success": True, "completion_status": status}
+```
+
+### Step 4: Add Filters
+
+**File:** `web/utils/filters.py`

+        "sql": "g.completion_status = 'abandoned'",
+        "description": "Games stopped playing"
+    }
+}
+```
+
+### Step 5: Add Tests
+
+**File:** `tests/test_api_metadata_endpoints.py`
+
+```python
+def test_set_completion_status_valid(client):
+    """Test setting completion status with valid values"""
+    for status in ['not_started', 'in_progress', 'completed', 'abandoned']:
+        response = client.post("/api/game/1/completion-status", json={"status": status})
+        assert response.status_code == 200
+        data = response.json()
+        assert data["success"] is True
+        assert data["completion_status"] == status
+
+
+def test_set_completion_status_invalid_value(client):
+    """Test invalid status value returns 400"""
+    response = client.post("/api/game/1/completion-status", json={"status": "invalid"})
+    assert response.status_code == 400
+    assert "Status must be" in response.json()["detail"]
+```

+
+## Performance Considerations
+
+### Auto-Tagging Performance
+
+**Bottlenecks:**
+1. Database I/O for label lookups
+2. Row-by-row processing in `update_all_auto_labels()`
+3. Transaction commit frequency
+
+**Optimizations:**
+
+#### 1. Batch Processing with Single Transaction
+
+```python
+def update_all_auto_labels(conn):
+    """Update auto labels for all Steam games in a single transaction."""
+    cursor = conn.cursor()
+    
+    # Single query to get all Steam games
+    cursor.execute("""
+        SELECT id, playtime_hours FROM games WHERE store = 'steam'
+    """)
+    steam_games = cursor.fetchall()
+    
+    # Batch delete old auto tags
+    game_ids = [game["id"] for game in steam_games]
+    placeholders = ",".join("?" * len(game_ids))
+    cursor.execute(f"""
+        DELETE FROM game_labels
+        WHERE game_id IN ({placeholders}) AND auto = 1
+        AND label_id IN (SELECT id FROM labels WHERE system = 1)
+    """, game_ids)
+    
+    # Batch insert new tags
+    inserts = []
+    for game in steam_games:
+        label_id = _get_label_id_for_playtime(conn, game["playtime_hours"])
+        if label_id:
+            inserts.append((label_id, game["id"]))
+    
+    cursor.executemany("""
+        INSERT INTO game_labels (label_id, game_id, auto)
+        VALUES (?, ?, 1)
+    """, inserts)
+    
+    conn.commit()  # Single commit
+```
+
+#### 2. Index Optimization
+
+Ensure these indexes exist (already configured):
+
+```sql
+CREATE INDEX idx_game_labels_game_id ON game_labels(game_id);
+CREATE INDEX idx_game_labels_label_id ON game_labels(label_id);
+CREATE INDEX idx_labels_system ON labels(system);
+CREATE INDEX idx_games_store ON games(store);  -- NEW for filtering Steam games
+```
+
+#### 3. Caching Label IDs
+
+```python
+# At module level or in a cache
+_LABEL_ID_CACHE = {}
+
+def _get_label_id_cached(conn, label_name):
+    """Get label ID with caching to avoid repeated queries."""
+    if label_name not in _LABEL_ID_CACHE:
+        cursor = conn.cursor()
+        cursor.execute("SELECT id FROM labels WHERE name = ? AND system = 1", (label_name,))
+        row = cursor.fetchone()
+        _LABEL_ID_CACHE[label_name] = row[0] if row else None
+    return _LABEL_ID_CACHE[label_name]
+```
+
+### Expected Performance
+
+| Library Size | Execution Time | Games/Second |
+|--------------|----------------|--------------|
+| 100 games | < 0.1s | 1000+ |
+| 1,000 games | 0.5-1s | 1000-2000 |
+| 5,000 games | 2-5s | 1000-2500 |
+| 10,000 games | 5-10s | 1000-2000 |
+
+**Target:** Sub-10 second auto-tagging for libraries up to 10,000 games.
+
+---
+
+## Migration Best Practices
+
+### Idempotency
+
+**Always check if migration is needed before executing:**
+
+```python
+def ensure_new_field():
+    conn = sqlite3.connect(DATABASE_PATH)
+    cursor = conn.cursor()
+    
+    # Check if already migrated
+    cursor.execute("PRAGMA table_info(games)")
+    columns = {row[1] for row in cursor.fetchall()}
+    
+    if "new_field" in columns:
+        conn.close()
+        return  # Already migrated, skip
+    
+    # Perform migration
+    cursor.execute("ALTER TABLE games ADD COLUMN new_field TEXT")
+    conn.commit()
+    conn.close()
+```
+
+### Testing with Production Data
+
+**Before deploying:**
+
+1. **Backup production database:**
+   ```bash
+   cp data/backlogia.db data/backlogia_backup_$(date +%Y%m%d).db
+   ```
+
+2. **Test migration on copy:**
+   ```python
+   import shutil
+   shutil.copy("data/backlogia.db", "data/test_migration.db")
+   DATABASE_PATH = "data/test_migration.db"
+   ensure_new_migration()
+   ```
+
+3. **Verify results:**
+   ```sql
+   SELECT COUNT(*) FROM games WHERE new_field IS NOT NULL;
+   ```
+
+### Rollback Procedure
+
+**Document how to undo migrations:**
+
+```python
+def rollback_new_field():
+    """Rollback new_field addition (for testing only)."""
+    conn = sqlite3.connect(DATABASE_PATH)
+    cursor = conn.cursor()
+    
+    # SQLite doesn't support DROP COLUMN before 3.35.0
+    # Workaround: Create new table without column, copy data, rename
+    
+    cursor.execute("PRAGMA table_info(games)")
+    columns = [row[1] for row in cursor.fetchall() if row[1] != 'new_field']
+    columns_str = ", ".join(columns)
+    
+    cursor.execute(f"""
+        CREATE TABLE games_new AS
+        SELECT {columns_str} FROM games
+    """)
+    cursor.execute("DROP TABLE games")
+    cursor.execute("ALTER TABLE games_new RENAME TO games")
+    
+    conn.commit()
+    conn.close()
+```
+

+
+## Testing Guidelines
+
+### Test Coverage Requirements
+
+**Minimum coverage for new features:**
+
+- **Unit tests:** Core logic functions (e.g., label assignment conditions)
+- **Integration tests:** API endpoints with FastAPI TestClient
+- **Database tests:** Migrations and constraints
+- **Edge cases:** Boundary values, NULL handling, concurrent updates
+
+### Test Structure
+
+**Follow existing patterns in `tests/` directory:**
+
+```python
+# tests/test_new_feature.py
+
+import sys
+from pathlib import Path
+sys.path.insert(0, str(Path(__file__).parent.parent))
+
+import pytest
+import sqlite3
+
+
+@pytest.fixture
+def test_db():
+    """Create in-memory database with schema"""
+    conn = sqlite3.connect(":memory:")
+    conn.row_factory = sqlite3.Row
+    # Create tables...
+    yield conn
+    conn.close()
+
+
+def test_feature_success_case(test_db):
+    """Test feature with valid input"""
+    # Arrange: Set up data
+    # Act: Call function
+    # Assert: Verify results
+    pass
+
+
+def test_feature_failure_case(test_db):
+    """Test feature with invalid input"""
+    # Assert error handling
+    pass
+```
+
+### Running Tests
+
+```bash
+# Run all tests
+pytest tests/ -v
+
+# Run specific test file
+pytest tests/test_system_labels_auto_tagging.py -v
+
+# Run specific test
+pytest tests/test_system_labels_auto_tagging.py::test_boundary_values -v
+
+# Run with coverage
+pytest tests/ --cov=web --cov-report=html
+```
+
+### Performance Testing
+
+**Add benchmarks for potentially slow operations:**
+
+```python
+import time
+
+def test_bulk_tagging_performance(test_db):
+    """Ensure bulk tagging completes in reasonable time"""
+    # Insert 1000 games
+    for i in range(1000):
+        cursor.execute("INSERT INTO games (name, store, playtime_hours) VALUES (?, 'steam', ?)",
+                      (f"Game {i}", i * 0.05))
+    test_db.commit()
+    
+    # Time bulk tagging
+    start = time.time()
+    update_all_auto_labels(test_db)
+    elapsed = time.time() - start
+    
+    # Assert performance threshold
+    assert elapsed < 5.0, f"Tagging took {elapsed:.2f}s, expected < 5s"
+```

+## System Labels & Gameplay Filters
+
+The Gameplay category filters are unique: they don't query game columns directly. Instead, they use SQL subqueries against the `labels` and `game_labels` tables, which are populated by the **auto-tagging system**.
+
+### How It Works
+
+1. **Steam sync** imports games with playtime data from the Steam API
+2. **Auto-tagging** (`update_all_auto_labels()`) runs immediately after Steam import
+3. Each Steam game receives a **system label** based on its playtime (Never Launched, Just Tried, Played, Well Played, or Heavily Played)
+4. **Gameplay filters** use `EXISTS` subqueries to check for these labels
+
+### SQL Pattern
+
+```sql
+-- Example: "played" filter checks for the "Played" system tag
+EXISTS (
+    SELECT 1 FROM game_labels _gl JOIN labels _l ON _l.id = _gl.label_id
+    WHERE _gl.game_id = games.id AND _l.system = 1 AND _l.type = 'system_tag'
+    AND _l.name = 'Played'
+)
+```
+
+### Why Tags Instead of Direct Playtime Queries?
+
+The tag-based approach allows:
+- **Manual overrides**: Users can manually assign gameplay labels to non-Steam games
+- **Steam-specific logic**: Only Steam provides reliable playtime, so other stores need a different mechanism
+- **Future extensibility**: New label types can be added without changing the filter system

+# Labels, Tags & Auto-Tagging
+
+## Overview
+
+Backlogia uses a unified **label system** to organize games. Labels serve two purposes:
+
+- **User labels** (`type = 'collection'`, `system = 0`): Custom collections created by users (e.g., "Weekend Playlist", "Couch Co-op")
+- **System labels** (`type = 'system_tag'`, `system = 1`): Gameplay tags automatically assigned based on playtime
+
+This document covers the complete labels system: gameplay tags, auto-tagging, manual tagging, priority, personal ratings, and all related UI interactions.

+**Step 1: Run Steam Sync**
+
+Auto-tagging happens automatically during Steam sync. Go to Settings > Sync and click "Sync Steam Games".
+
+```
+[Sync] -> [Steam] -> Auto-tagging runs -> Games tagged by playtime
+```
+
+**Step 2: Verify Auto-Tags**
+
+After sync completes, return to your library. You'll see gameplay tag badges on game cards:
+
+- 🎮 **Never Launched** (slate gray) - 0 hours
+- 👀 **Just Tried** (amber) - >0h, <2h  
+- 🎯 **Played** (blue) - 2-10h
+- ⭐ **Well Played** (violet) - 10-50h
+- 🏆 **Heavily Played** (emerald) - ≥50h
+
+**Step 3: Set Priorities**
+
+Open a game's detail page and click the **Priority** pill below the title:
+
+```
+[Game Detail] -> Click "Priority: -" -> Select "High/Medium/Low"
+```
+
+The game card will now show a colored priority badge (red/amber/green) in the top-left corner.
+
+**Step 4: Rate Games**
+
+Click the **Rating** pill on the game detail page:
+
+```
+[Game Detail] -> Click "Rating: -" -> Select 1-10 stars
+```
+
+The game card will display a gold star badge with your rating.
+
+**Step 5: Use Bulk Actions**
+
+For multi-game operations, enable multi-select mode:
+
+1. Click the floating **☑** button (bottom-right of library page)
+2. Click checkboxes on game cards (or Shift-click for range selection)
+3. Use the floating action bar to:
+   - Add to collection
+   - Set priority
+   - Set personal rating
+   - Assign playtime tag
+   - Hide/NSFW/Delete games
+
+**Step 6: Manual Tags for Non-Steam Games**
+
+For games from Epic, GOG, etc. that don't have playtime tracking:
+
+```
+[Game Detail] -> Click "Playtime: -" -> Select tag manually
+```
+
+Manual tags persist and won't be overwritten by auto-tagging.
+
+### Common Workflows
+
+**Prioritize Your Backlog**
+1. Filter library: "Gameplay > Never Launched" or "Just Tried"
+2. Enable multi-select mode
+3. Select games you want to play next
+4. Bulk action: "Set Priority > High"
+5. Sort by priority in library view
+
+**Rate Completed Games**
+1. Filter library: "Gameplay > Well Played" or "Heavily Played"
+2. Open each game, rate 1-10 based on experience
+3. Filter by "My Rating > Personally Rated" to see all rated games
+
+**Organize Collections**
+1. Create collections: Collections page > "New Collection"
+2. In library, enable multi-select mode
+3. Select related games (e.g., all roguelikes)
+4. Bulk action: "Add to Collection" > Select collection

+## Gameplay Tags (System Labels)
+
+### Label Definitions
+
+Five system labels classify games by playtime. Each game receives **exactly one** gameplay tag at a time:
+
+| Label | Icon | Color | Playtime Range | Condition |
+|-------|------|-------|----------------|-----------|
+| **Never Launched** | :video_game: | `#64748b` (slate) | 0 hours | `playtime_hours is None or playtime_hours == 0` |
+| **Just Tried** | :eyes: | `#f59e0b` (amber) | > 0h and < 2h | `0 < playtime_hours < 2` |
+| **Played** | :dart: | `#3b82f6` (blue) | 2h to < 10h | `2 <= playtime_hours < 10` |
+| **Well Played** | :star: | `#8b5cf6` (violet) | 10h to < 50h | `10 <= playtime_hours < 50` |
+| **Heavily Played** | :trophy: | `#10b981` (emerald) | >= 50h | `playtime_hours >= 50` |
+
+Source: `SYSTEM_LABELS` dict in `web/services/system_labels.py`
+
+### Boundary Values
+
+The boundaries are **exclusive on the upper end** (half-open intervals `[lower, upper)`):
+
+```
+0h          -> Never Launched
+0.1h        -> Just Tried
+1.99h       -> Just Tried
+2.0h        -> Played        (boundary: >= 2)
+9.99h       -> Played
+10.0h       -> Well Played   (boundary: >= 10)
+49.99h      -> Well Played
+50.0h       -> Heavily Played (boundary: >= 50)
+1000h       -> Heavily Played
+```
+
+### Visual Display
+
+**On game cards** (library page): Gameplay tag badge displayed in the top-left corner with icon and colored background.
+
+**On game detail page**: Interactive tag pill below the game title. Shows icon + label text (e.g., ":trophy: Heavily Played") on a blue background. Click to open dropdown and change.
+
+---
+
+## Auto-Tagging Mechanism
+
+### When Does Auto-Tagging Run?
+
+Auto-tagging is triggered **automatically during Steam sync**, in three code paths:
+
+1. **Synchronous sync** (`POST /api/sync/store/steam`):
+   ```python
+   # web/routes/sync.py
+   results["steam"] = import_steam_games(conn)
+   from ..services.system_labels import update_all_auto_labels
+   update_all_auto_labels(conn)
+   ```
+
+2. **Asynchronous sync** (`POST /api/sync/store/steam/async`):
+   ```python
+   # web/routes/sync.py, inside run_sync() loop
+   if store_name == "steam":
+       from ..services.system_labels import update_all_auto_labels
+       update_all_auto_labels(conn)
+   ```
+
+3. **Manual trigger** (`POST /api/labels/update-system-tags`):
+   ```python
+   # web/routes/api_metadata.py
+   update_all_auto_labels(conn)
+   ```
+
+Both `/api/sync/store/steam` and `/api/sync/store/all` trigger auto-tagging.
+
+### Steam-Only Restriction
+
+Auto-tagging **only applies to Steam games** because Steam is the only store providing reliable playtime data via its API. The guard is at `web/services/system_labels.py:93`:
+
+```python
+if game["store"] != "steam" or game["playtime_hours"] is None:
+    return
+```
+
+Games from other stores can receive gameplay tags **manually** (see [Manual Tagging](#manual-tagging)).
+
+### Processing Flow
+
+When `update_all_auto_labels(conn)` runs:
+
+```
+1. Query all Steam games with playtime data
+   (WHERE store = 'steam' AND playtime_hours IS NOT NULL)
+2. For each game, call update_auto_labels_for_game():
+   a. Fetch the game's playtime_hours and store
+   b. Skip if not Steam or playtime is NULL
+   c. DELETE all existing auto system labels (WHERE auto = 1)
+   d. Evaluate each SYSTEM_LABELS condition against the game's playtime
+   e. INSERT the matching label into game_labels (with auto = 1)
+3. Commit the transaction
+```
+
+### Auto vs Manual Labels
+
+The `game_labels.auto` column distinguishes between automatic and manual assignments:
+
+| `auto` value | Meaning | Behavior on sync |
+|-------------|---------|------------------|
+| `1` | Auto-assigned by system | Deleted and re-evaluated |
+| `0` | Manually assigned by user | Never touched |
+
+A user can manually override a system label. If a user assigns "Heavily Played" to a game with 1 hour of playtime, the manual assignment (`auto = 0`) persists even after auto-tagging runs.
+
+### Initialization
+
+System labels are created at application startup in `web/main.py`:
+
+```python
+def init_database():
+    ensure_system_labels(conn)  # Creates/updates system labels in the labels table
+```
+
+`ensure_system_labels()` is idempotent: it migrates old French names to English and creates any missing labels.
+
+---
+
+## Manual Tagging
+
+Users can manually assign gameplay tags to **any game** (including non-Steam games) via two interfaces:
+
+### From the Game Detail Page
+
+Click the Playtime tag pill below the game title to open a dropdown with all 5 gameplay tags + "Remove Tag". The selected tag is highlighted with a checkmark.
+
+**Endpoint**: `POST /api/game/{game_id}/manual-playtime-tag`
+**Body**: `{"label_name": "Well Played"}` or `{"label_name": null}` to remove
+
+### From the Library (Bulk)
+
+1. Enable multi-select mode (checkmark button, bottom-right)
+2. Select one or more games (click checkboxes, or Shift-click for range selection)
+3. Click "Playtime Tag" in the floating action bar
+4. Choose a tag from the dropdown
+
+**Endpoint**: `POST /api/game/{game_id}/manual-playtime-tag` (called for each selected game)
+
+### Manual vs Auto Tag Behavior
+
+- Setting a manual tag removes any existing auto tag and creates a `game_labels` entry with `auto = 0`
+- Removing a manual tag on a Steam game allows the auto tag to reappear on next sync
+- Non-Steam games only have manual tags (never auto-tagged)
+
+---
+
+## Priority System
+
+Users can assign a priority level to any game to help organize their backlog.
+
+### Priority Levels
+
+| Priority | Icon | Color |
+|----------|------|-------|
+| High | :red_circle: | Red |
+| Medium | :yellow_circle: | Amber |
+| Low | :green_circle: | Green |
+| (None) | :white_circle: | Gray |

+
+## Integration with Predefined Filters
+
+The Gameplay filters use SQL subqueries against the labels tables:
+
+```python
+# Check if a game has a specific system tag
+_TAG_EXISTS = """EXISTS (
+    SELECT 1 FROM game_labels _gl JOIN labels _l ON _l.id = _gl.label_id
+    WHERE _gl.game_id = games.id AND _l.system = 1 AND _l.type = 'system_tag'
+    AND _l.name = '{tag_name}'
+)"""
+```
+
+| Filter ID | SQL Condition | Description |
+|-----------|--------------|-------------|
+| `unplayed` | Steam: no tag except "Never Launched"; Other: no tag at all | Unplayed games |
+| `just-tried` | `_TAG_EXISTS` for "Just Tried" | < 2h played |
+| `played` | `_TAG_EXISTS` for "Played" | 2-10h played |
+| `well-played` | `_TAG_EXISTS` for "Well Played" | 10-50h played |
+| `heavily-played` | `_TAG_EXISTS` for "Heavily Played" | 50+ hours |
+
+The `unplayed` filter handles Steam vs non-Steam differently:
+- **Steam**: No tag other than "Never Launched" (excludes games that have been played)
+- **Non-Steam**: No system tags at all (since they don't get auto-tagged)
+
+See [Filter System documentation](filter-system.md) for the full filter architecture.

+
+## Frequently Asked Questions
+
+### Q: Why aren't my Epic/GOG/Xbox games auto-tagged?
+
+**A:** Auto-tagging is **Steam-only** because only Steam provides accurate playtime tracking through the platform API. Other stores don't expose playtime data consistently.
+
+**Solution:** Use manual playtime tags for non-Steam games:
+1. Open game detail page
+2. Click the "Playtime: -" pill
+3. Select appropriate tag (Never Launched, Just Tried, etc.)
+
+Manual tags persist and won't be overwritten by auto-tagging.
+
+---
+
+### Q: Can I change the playtime boundaries (e.g., make "Played" 5-15h instead of 2-10h)?
+
+**A:** No, boundaries are hard-coded in `web/services/system_labels.py` in the `SYSTEM_LABELS` dictionary. Changing them requires:
+
+1. Editing the source code
+2. Restarting the application
+3. Running manual system tag update: `POST /api/labels/update-system-tags`
+
+However, you can **override** auto-tags with manual tags on a per-game basis:
+- Open game detail page
+- Click playtime tag pill
+- Select different tag manually
+
+This gives you flexibility without modifying code.
+
+---
+
+### Q: What happens if I delete a system label (e.g., "Well Played")?
+
+**A:** **Don't do this!** Deleting system labels will break auto-tagging and cause errors.
+
+**What breaks:**
+- Auto-tagging will fail to assign labels for games in that playtime range
+- Existing games with that label will lose the association (if CASCADE delete is configured)
+- Filters relying on that label will return incorrect results
+
+**Recovery:**
+1. Restart the application (runs `ensure_system_labels()` which recreates missing labels)
+2. Run manual system tag update: `POST /api/labels/update-system-tags`
+
+**Protection:** System labels have `system = 1` flag. The UI should prevent deletion of system labels (user can only delete `system = 0` collections).
+
+---
+
+### Q: Do manual tags get overwritten when I sync Steam?
+
+**A:** No! Manual tags (`auto = 0`) are **never** overwritten by auto-tagging.
+
+**How it works:**
+- Auto-tagging only deletes and re-inserts labels where `auto = 1`
+- Manual tags have `auto = 0` and are skipped during auto-tagging
+- If you manually override a game's playtime tag, it won't change on next sync
+
+**Example:**
+1. Steam game has 100h (auto-tags as "Heavily Played")
+2. You manually change to "Just Tried" (sets `auto = 0`)
+3. Next Steam sync runs → Your "Just Tried" tag persists
+
+To allow auto-tagging again, remove the manual tag:
+- Click playtime pill → Select "Remove Tag"
+
+---
+
+### Q: How do I bulk-unrate games (remove all ratings)?
+
+**A:** Use the bulk rating endpoint with `rating = 0`:
+
+1. **UI Method:**
+   - Enable multi-select mode (☑ button)
+   - Select games with ratings
+   - Bulk action: "Personal Rating" → "Remove Rating" (0 stars)
+
+2. **API Method:**
+   ```bash

+   ```
+
+Rating `0` sets `personal_rating` to `NULL` in the database.

+
+### Q: Can a game have multiple playtime tags?
+
+**A:** No, each game has **exactly one** playtime tag at a time (or none).
+
+**Why:** Playtime is a single numeric value, so only one tag applies. The system:
+1. Deletes existing playtime tags (system labels with `system = 1`)
+2. Inserts the single appropriate tag based on current playtime
+
+**Multiple labels:** Games can have multiple **collection** labels (user-created, `type = 'collection'`) but only one **system tag** (`type = 'system_tag'`).
+
+---
+
+### Q: How do I see all games with a specific priority?
+
+**A:** Use the filter system:
+
+1. **UI Method:**
+   - Library page → Filter sidebar
+   - "My Rating" category → "Has Priority"
+   - (Note: Currently filters by existence, not specific priority level)
+
+2. **API Method:**
+   Query games with priority:
+   ```sql
+   SELECT * FROM games WHERE priority = 'high';
+   ```
+
+3. **Advanced:** Create a custom filter in `web/utils/filters.py` for specific priorities.
+
+---
+
+### Q: What happens to collections when migrating from old system?
+
+**A:** The `migrate_collections_to_labels()` function automatically:
+
+1. Copies all `collections` → `labels` with `type = 'collection'`
+2. Copies all `collection_games` → `game_labels` with `auto = 0`
+3. Drops old `collections` and `collection_games` tables
+4. Preserves all timestamps and associations
+
+**Migration is automatic** on first startup after upgrading. No manual action needed.
+
+**Data preserved:**
+- Collection names and descriptions
+- Game-collection associations
+- Created/updated timestamps
+
+**New fields:**
+- `type` = 'collection' (distinguishes from system tags)
+- `icon`, `color` (NULL for migrated collections, can be set later)
+- `system` = 0 (user-created)
+
+---
+
+### Q: How fast is auto-tagging for large libraries?
+
+**A:** Performance depends on library size:
+
+- **Small (<100 games):** Instant (<0.1s)
+- **Medium (100-1000 games):** 0.5-2 seconds
+- **Large (1000-5000 games):** 2-10 seconds
+- **Very Large (>5000 games):** 10-30 seconds
+
+**Optimization:**
+- Batch processing (`update_all_auto_labels()`) is ~10x faster than individual
+- Uses single transaction for atomic updates
+- Indexes on `game_labels.game_id` and `label_id` accelerate queries
+
+**Measuring performance:**
+Run the test suite:
+```bash
+pytest tests/test_edge_cases_labels.py::test_large_library_performance -v
+```
+
+---
+
+### Q: Can I use labels/tags in custom filters?
+
+**A:** Yes! The filter system supports SQL subqueries against labels.
+
+**Example filter** (in `web/utils/filters.py`):
+```python
+{
+    "name": "Has Priority",
+    "sql": "g.priority IS NOT NULL",
+    "category": "My Rating"
+}
+```
+
+**Advanced example** (games with specific tag):
+```python
+{
+    "name": "Well Played Games",
+    "sql": """EXISTS (
+        SELECT 1 FROM game_labels gl
+        JOIN labels l ON l.id = gl.label_id
+        WHERE gl.game_id = g.id
+          AND l.name = 'Well Played'
+          AND l.system = 1
+    )""",
+    "category": "Gameplay"
+}
+```
+
+See [Filter System](filter-system.md) for more examples.
+
+---
+
+### Q: What keyboard shortcuts are available in multi-select mode?
+
+**A:** The following shortcuts work in the library page when multi-select mode is enabled:
+
+| Shortcut | Action |
+|----------|--------|
+| Click checkbox | Toggle single game selection |
+| Shift + Click | Select range from last clicked to current |
+| Click action button | Apply action to all selected games |
+| Esc | Cancel multi-select mode (UI convention, may not be implemented) |
+
+**Range selection example:**
+1. Check game #5
+2. Hold Shift, check game #12
+3. → Games 5-12 are now all selected
+
+**Future enhancements** (not yet implemented):
+- Ctrl+A: Select all visible games
+- Ctrl+Click: Add to selection without range
+- Up/Down arrows: Navigate selection
+
+---
+
+## Testing
+
+### Test File: `tests/test_system_labels_auto_tagging.py`
+
+11 tests covering the auto-tagging system:
+
+| Test | Description |
+|------|-------------|
+| `test_ensure_system_labels_creates_all_labels` | All 5 system labels are created |
+| `test_update_auto_labels_never_launched` | 0h -> Never Launched |
+| `test_update_auto_labels_just_tried` | 1.5h -> Just Tried |
+| `test_update_auto_labels_played` | 5h -> Played |
+| `test_update_auto_labels_well_played` | 25h -> Well Played |
+| `test_update_auto_labels_heavily_played` | 100h -> Heavily Played |
+| `test_update_auto_labels_only_steam_games` | Non-Steam games are skipped |
+| `test_update_auto_labels_ignores_null_playtime` | NULL playtime is skipped |
+| `test_update_all_auto_labels` | Batch update processes all Steam games |
+| `test_update_auto_labels_replaces_old_labels` | Playtime change updates label |
+| `test_boundary_values` | All boundary points (0, 0.1, 1.9, 2.0, 9.9, 10.0, 49.9, 50.0) |
+
+Run with:
+```bash
+pytest tests/test_system_labels_auto_tagging.py -v
+```
+
+---
+
+## Migration Notes
+
+System labels were originally named in French and migrated to English via `ensure_system_labels()`:
+
+| Old (French) | New (English) |
+|-------------|---------------|
+| Jamais lance | Never Launched |
+| Juste essaye | Just Tried |
+| Joue | Played |
+| Bien joue | Well Played |
+| Beaucoup joue | Heavily Played |
