## Review: Unified Slack-to-Queue Autonomous Pipeline

**Reviewing as Andrej Karpathy**

VERDICT: **approve**

FINDINGS:
- **[src/colonyos/slack.py]**: Triage prompt design is solid — structured JSON output, no tool access (`allowed_tools=[]`), $0.05 budget cap. The system fails closed on malformed LLM output (returns `actionable=False`). This is exactly the right failure mode for an always-on autonomous agent.
- **[src/colonyos/slack.py]**: `Phase.PLAN` reused as triage tag — minor smell that could conflate cost tracking. Not blocking.
- **[src/colonyos/slack.py]**: Prompt injection defense is layered: sanitized input + no tools + structured output validation. Blast radius of successful injection is limited to a wrong JSON classification.
- **[src/colonyos/cli.py]**: Watch→queue unification is architecturally clean (producer-consumer with state lock + semaphore). Daily budget correctly pauses without breaking the main loop.
- **[src/colonyos/cli.py]**: `slack_client_ref` threading pattern is pragmatic but slightly fragile — no synchronization ensuring client is available before executor starts. Guarded by `if slack_client_ref else None` but worth noting.
- **[src/colonyos/orchestrator.py]**: Base branch validation with remote fetch fallback is thorough. PR targeting via prompt instruction to deliver agent is acceptable for v1.
- **[src/colonyos/config.py]**: `daily_budget_usd` defaults to `None` (no default) — correct safety choice for always-on operation.
- **[tests/]**: 342 tests pass. Comprehensive coverage including malformed JSON parsing, backward compatibility, daily cost reset, edge cases.

SYNTHESIS:
This is a well-executed implementation that turns ColonyOS from a CLI tool into an always-on autonomous agent. The key architectural decisions are sound: (1) the triage agent is a single-turn, no-tool, haiku-class call — the cheapest possible way to get semantic understanding while keeping prompt injection blast radius near zero; (2) the watch→queue unification uses a clean producer-consumer pattern with proper thread synchronization; (3) budget controls are layered (per-run, aggregate, daily) with fail-closed defaults. The triage prompt is well-engineered as a program — it specifies exact output format, rules, and context, and the parser validates defensively. Production-ready with good safety properties for autonomous operation.
