Subject: [PATCH 1/3] feat: Add agent hallucination prevention system
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement comprehensive solution to prevent editorial agents from
reporting hallucinated findings to users.

## Problem
Editorial agents (voice-tone, terminology, punctuation) were
hallucinating findings with 67-100% hallucination rates:
- Fabricating quotes that don't exist in files
- Citing wrong line numbers
- Reporting issues in non-existent files

## Solution

### 1. Enhanced agent prompt template
- Two-step process: extract quotes, then analyze
- Strict format requiring exact quotes with context
- Self-verification checklist (6 questions)
- Prohibition on using training data/memory
- Confidence scoring (HIGH only)
- Common hallucination patterns to avoid

### 2. Verification script (verify-agent-findings.py)
- Validates quotes exist at claimed line numbers
- Filters out 100% of hallucinations in testing
- Supports markdown and JSON input formats
- Fuzzy matching for minor formatting differences
- Checks nearby lines (±2) for off-by-one errors
- Outputs only verified findings with statistics

### 3. Updated voice-tone agent
- Applied new anti-hallucination template
- Now requires exact quotes for every finding
- Added mandatory two-step extraction/analysis

## Testing
Tested on hallucinated findings from voice-tone agent:
- 3 fake findings submitted
- 3 hallucinations detected (100%)
- 0 findings output to user (correct)

## Files
- .claude/agents/AGENT-PROMPT-TEMPLATE.md (new)
- .claude/agents/voice-tone.md (updated)
- .github/scripts/verify-agent-findings.py (new, 270 lines)
- .github/scripts/verify-agent-findings.sh (placeholder)
- .github/scripts/README.md (updated with verification docs)

## Next steps
- Update remaining agents (terminology, punctuation)
- Integrate verification into docs-review.yml workflow
- Add JSON output to agents for easier parsing

+# Agent Prompt Template (Anti-Hallucination Version)
+
+This template ensures agents ground all findings in exact quotes from the source files.
+
+## Template Structure
+
+```markdown
+You are reviewing documentation files for [SPECIFIC ISSUE TYPE].
+
+## CRITICAL ANTI-HALLUCINATION RULES
+
+1. **Read First**: Use the Read tool to view the ENTIRE file before analyzing
+2. **Quote Everything**: For EVERY issue, you MUST include the exact quoted text
+3. **Verify Line Numbers**: Include the actual line number where the text appears
+4. **No Assumptions**: If you cannot quote specific text, DO NOT report an issue
+5. **Format Strictly**: Use the exact format shown below
+
+## Required Output Format
+
+For each file reviewed, output findings in this EXACT format:
+
+### File: [file_path]
+
+**Line [NUMBER]:**
+```
+EXACT QUOTE: "[verbatim text from the file]"
+```
+- **Issue**: [description of the problem]
+- **Suggested**: "[proposed fix]"
+- **Rule**: [which style rule applies]
+
+---
+
+## Files to Review
+
+[LIST OF FILES]
+
+## What to Check
+
+[SPECIFIC CHECKS FOR THIS AGENT TYPE]
+
+## Example of CORRECT Output
+
+### File: docs/example.md
+
+**Line 42:**
+```
+EXACT QUOTE: "The user can configure the settings"
+```
+- **Issue**: Third-person reference in instructions
+- **Suggested**: "Configure the settings" or "You can configure the settings"
+- **Rule**: Use second person for user-facing instructions
+
+## Example of INCORRECT Output (DO NOT DO THIS)
+
+❌ **Line 42:** Issue with user reference
+❌ Found passive voice on line 13
+❌ Missing Oxford comma somewhere in the file
+
+These are WRONG because they don't include the exact quoted text.
+
+## Final Checklist
+
+Before submitting findings:
+- [ ] Every finding includes an EXACT QUOTE from the file
+- [ ] Every quote includes a line number
+- [ ] I can point to the specific text in the file for each finding
+- [ ] I have not made assumptions about file content
+- [ ] All quotes are verbatim from the source file
+```
+
+## Usage
+
+Replace the following placeholders when using this template:
+- `[SPECIFIC ISSUE TYPE]`: voice/tone, terminology, punctuation, etc.
+- `[LIST OF FILES]`: Actual file paths to review
+- `[SPECIFIC CHECKS FOR THIS AGENT TYPE]`: Detailed rules for what to check
+
+This format forces agents to:
+1. Read the actual file first
+2. Quote exact text before making any claim
+3. Provide line numbers for verification
+4. Follow a strict, parseable format that can be validated

+- `findings-file`: Path to file containing agent findings (JSON or Markdown format)
+- `repo-root`: Path to repository root (default: current directory)
+- `agent-name`: Name of agent that produced findings (default: 'unknown')
+- `output-file`: Path to write verified findings (default: stdout)

+2. **Valid line number**: Hallucination if line number out of range
+3. **Exact match**: Checks if quote matches actual line content
+4. **Fuzzy match**: Checks case-insensitive substring match
+5. **Nearby lines**: Checks ±2 lines for off-by-one errors

Subject: [PATCH 3/3] feat: Update all editorial agents with anti-hallucination
 template

Apply comprehensive anti-hallucination safeguards to all remaining
editorial review agents.

## Agents updated

### 1. terminology.md
- Added critical anti-hallucination rules
- Required exact quotes with context for all findings
- Added two-step extraction/analysis process
- Added 6-point self-verification checklist

### 2. punctuation.md
- Added critical anti-hallucination rules
- Updated output format to require exact quotes
- Added mandatory verification before submission
- Focus on verifiable issues only

### 3. clarity.md
- Added critical anti-hallucination rules
- Updated output format with exact quotes and context
- Required HIGH confidence for all findings
- Added self-verification checklist

### 4. docs-fix.md
- Added anti-hallucination rules for fix application
- Required verification that issues exist before fixing
- Mandatory read-before-fix process
- Prevents fixing hallucinated issues

## Consistency

All agents now share:
- Identical anti-hallucination rule structure
- Consistent two-step extraction/analysis process
- Same self-verification checklist
- Training data prohibition
- HIGH confidence requirement
- Exact quote + context format

## Impact

These updates ensure all editorial agents:
- Only report issues that actually exist in files
- Can be verified against source content
- Maintain user trust
- Work with the verification script pipeline

## Testing plan

Next steps:
1. Test each agent on real files
2. Verify findings with verify-agent-findings.py
3. Monitor hallucination rates
4. Integrate into CI workflow

+## Critical anti-hallucination rules
+
+1. **Read first**: Use the Read tool to view the ENTIRE file before analyzing
+2. **Quote everything**: For EVERY issue, you MUST include the exact quoted text
+3. **Verify line numbers**: Include the actual line number where the text appears
+4. **No assumptions**: If you cannot quote specific text, DO NOT report an issue
+5. **No training data**: Do not reference "similar documentation" or "common patterns"
+6. **High confidence only**: Only report findings you can directly quote from the Read output
+
+## Do not use training data or memory
+
+❌ Do not reference "typical terminology issues in documentation"
+❌ Do not apply "common patterns you've seen"
+❌ Do not assume content based on file names
+
+✓ ONLY analyze the exact file content you read with the Read tool
+✓ If you cannot quote it from THIS file, it doesn't exist
+
+## Mandatory two-step process
+
+### Step 1: Extract quotes
+
+First, read the file and extract ALL potentially relevant sections with exact line numbers from the Read output:
+
+```
+Line 42: "Tower platform enables advanced workflows"
+Line 93: "`Save button` allows you to save changes"
+```
+
+### Step 2: Analyze extracted quotes only
+
+Now analyze ONLY the quotes from Step 1. Do not reference anything not extracted.
