Add auto-review plugin that spawns cross-model review sessions on session.idle

[OpenCodeEngineer]

Summary

Create a new plugin at auto-review.ts following the same runtime pattern as reflection-3.ts.

Requirements

• Listen for session.idle and session.error
• Reuse the aborted-session cooldown/race handling pattern from reflection-3.ts
• Skip child sessions (parentID)
• Skip loops from prior review output
• Require at least 3 tool calls before reviewing
• Create a child review session using a different model than the source work
• Leave the review child session in place for reference
• Match existing code style and compile with TypeScript

Verification

• cd ~/workspace/opencode-plugins && npx tsc --noEmit auto-review.ts
• Run relevant existing tests/typechecks as needed

[OpenCodeEngineer]

Started work on this. I’m inspecting reflection-3.ts, then I’ll add auto-review.ts, verify TypeScript compilation, and open a PR once validated.

[OpenCodeEngineer]

Implementation is complete and validated locally.

Validation summary:

• npx tsc --noEmit --module es2022 --moduleResolution bundler auto-review.ts ✅
• npm run typecheck ✅
• npm test -- --runInBand ⚠️ existing unrelated test/telegram.test.ts failures caused by Supabase egress quota exhaustion; other suites pass, and failures are unrelated to auto-review.ts.

Next I’m committing the new plugin and opening a PR.

[OpenCodeEngineer]

The branch is now pushed. I’m opening the PR and then checking any PR status/checks.

The implementation is committed and pushed on branch issue-135-auto-review.

I attempted to open a PR via both GitHub MCP and gh, but the authenticated GitHub API identity is not recognized as a collaborator for PR creation (must be a collaborator).

Local validation remains:

• npx tsc --noEmit --module es2022 --moduleResolution bundler auto-review.ts ✅
• npm run typecheck ✅
• npm test -- --runInBand ⚠️ unrelated pre-existing test/telegram.test.ts failures from Supabase egress quota exhaustion
