# Review by Andrej Karpathy (Round 3)

## Review Complete

Here's my assessment as Andrej Karpathy:

**VERDICT: approve**

**Key strengths:**
- **Triage agent architecture is textbook correct** — single-turn haiku call, `allowed_tools=[]`, $0.05 budget cap, structured JSON output with safe fallback on parse failure. Treats the prompt as a program.
- **Defense-in-depth on LLM outputs** — `is_valid_git_ref` allowlist regex validated at both extraction and point-of-use, blocking prompt injection → command injection chains.
- **Circuit breaker with auto-recovery** for always-on operation — prevents runaway failures while avoiding permanent deadlocks.
- **Branch rollback in finally block** ensures the watch process doesn't get stranded.

**Recommendations for v2 (not blocking):**
1. **Add 2-3 few-shot examples to the triage prompt** — single highest-ROI change for hitting the >90% accuracy target
2. **Offload triage to a thread** — synchronous LLM call in Bolt event handler risks exceeding Slack's 3-second ack window
3. **Initialize Slack client from Bolt app** instead of the `slack_client_ref` mutable-list pattern
4. **Triage result extraction** is coupled to phase runner artifact internals — consider a more direct return path

All 422 tests pass. All 21 functional requirements implemented. No secrets, no TODOs, no new dependencies. Clean approve.
