When the runner passes a temp dir via session.create({ directory }), the SDK silently returns an empty response for non-project directories. Fix: spawn the server ourselves with cwd set to the case's working directory, then connect with createOpencodeClient. Also fixes variable shadowing, adds null guards on response.info and toolPart.state, uses PATH-resolved 'opencode' instead of hardcoded /opt/homebrew path, and adds post-build copy step for the .mjs ESM wrapper.

The server inherits the parent process's working directory and uses that as its project context. When the sniffbench runner creates a temp directory (via `mkdtempSync`) and passes it as `directory` in `session.create()`, the SDK silently returns an empty `{}` — no error, no parts, no info.

Should be externalized — read from opencode config file or a sniffbench config file. ## Key technical details - **ESM wrapper:** The `@opencode-ai/sdk` is ESM-only but the project is CommonJS. The `.mjs` wrapper in `src/agents/opencode-sdk.mjs` bridges this. tsc doesn't copy `.mjs` files, so the build script includes a manual `cp` step. - **Port management:** `nextPort` counter in opencode.ts increments per run to avoid collisions. Resets on process restart. -- **The SDK spawns a real opencode server process** per agent run. Each run gets its own server on a unique port, with the case's temp dir as cwd. The server is killed in the `finally` block. +- **Server lifecycle:** Each agent run spawns a real opencode server process on a unique port, with the case's temp dir as cwd. The server is killed in the `finally` block. +- **Event streaming:** Uses `client.event.subscribe()` (SSE) + `session.promptAsync()`. The stream object is at `sseResult.stream` (not `.data`). Events arrive as `message.part.updated` (tool calls, text, reasoning), `message.updated` (final tokens/cost), `session.status` (idle = done). +- **File snapshots:** After agent runs, `snapshotFiles()` in runner.ts walks the host tempDir and captures all files with a `changed` flag vs originals. Skips node_modules, .git, __pycache__, files >100KB. - **Score math:** `weightedScore = rawScore * weight / 100`. Overall score normalizes by participating weight fraction so excluded optional-only criteria don't affect the result. ## Git conventions From 54a4b5c8ef23bbe6a45885589986d76935a1e04c Mon Sep 17 00:00:00 2001 From: jharris1679 Date: Sat, 14 Feb 2026 16:54:17 -0500 Subject: [PATCH 12/19] fix: resolve SSE stream from correct property on subscribe result The SDK's event.subscribe() returns ServerSentEventsResult with the stream on .stream, not .data.
