## Review: Intent Router Agent — Andrej Karpathy

I've thoroughly reviewed the implementation on branch `colonyos/right_now_the_pipeline_always_runs_this_huge_planner_implementation_orchestratio` against the PRD.

### What's done well

The core router design is sound — this is the right architecture. Two-phase LLM calls (cheap classifier → appropriate handler) is exactly how you build cost-efficient agentic systems. The prompt for classification is clean: structured JSON output, clear category definitions, and fail-open behavior on parse failure. The Q&A agent with `allowed_tools=["Read", "Glob", "Grep"]` enforces proper sandboxing at the tool level. Tests are thorough for the modules that exist (82 passing), and the confidence-threshold fallback is correctly placed.

### Critical Issues

**1. `_log_router_decision` doesn't exist — runtime crash.**
`cli.py:613` imports `_log_router_decision` from `colonyos.router`, but this function is never defined in `router.py`. Every routed query in the `run` command will crash with an `ImportError`. This is a shipped bug, not a TODO — the call is wired in and will execute.

**2. Slack triage refactoring not started (FR-2, Task 8.0).**
The PRD's second goal is "Reuse existing infrastructure — extend the battle-tested `triage_message()` function." Zero lines changed in `slack.py`. The shared logic extraction hasn't happened. The router and Slack triage are now two completely parallel implementations that will drift.

**3. REPL integration missing (FR-4, Task 7.0).**
The PRD explicitly requires routing in the REPL path. No changes to `_run_repl()`. This is one of the two primary entry points.

**4. Audit logging not implemented (FR-8, Task 9.0).**
The function `_log_router_decision` is called but not defined. No `.colonyos/runs/triage_<timestamp>.json` file is ever written. The PRD requires all routing decisions to be logged with prompt, classification, confidence, source, and timestamp.

### Minor Issues

**5. Q&A model defaults to haiku, not configurable per the flow.** The `answer_question()` call in `cli.py:654` passes `config.router.model` — but the router model is the *classifier* model (haiku), not the Q&A answering model. The PRD suggests Q&A might use sonnet for better quality. These should be separate config fields, or at least the Q&A model should default higher than the classification model.

**6. No CLI integration tests.** Task 6.1 asks for integration tests for `colonyos run` with routing, but none exist. The `test_router.py` tests only cover the module internals; nothing tests the actual Click command wiring with `--no-triage`.

**7. Task file items all unchecked.** Every task in the task file is marked `- [ ]` (incomplete), yet tasks 1.0–6.0 are clearly implemented. This makes it hard to assess progress at a glance.

VERDICT: request-changes

FINDINGS:
- [src/colonyos/cli.py:613]: `_log_router_decision` imported but not defined in router.py — will crash at runtime with ImportError
- [src/colonyos/router.py]: Missing `_log_router_decision()` function — audit logging (FR-8, Task 9.0) not implemented
- [src/colonyos/slack.py]: Zero changes — shared triage refactoring (FR-2, Task 8.0) not started
- [src/colonyos/cli.py]: REPL integration (FR-4, Task 7.0) not implemented — `_run_repl()` unchanged
- [src/colonyos/cli.py:654]: Q&A model reuses classifier model config instead of separate Q&A model setting
- [tests/]: No CLI integration tests for `--no-triage` flag or routing behavior in `run()` command
- [cOS_tasks/]: All task checkboxes unchecked despite tasks 1-6 being implemented

SYNTHESIS:
The core design is good — prompts are treated as programs with structured JSON output, the two-phase architecture (cheap classifier → appropriate handler) is the right pattern for cost-efficient routing, and fail-open semantics are correctly applied everywhere. But this is about 60% complete. The implementation has a hard crash bug (`_log_router_decision` ImportError) that would fire on every routed query, and three of the four PRD entry points are missing integration (REPL, Slack, audit logging). The router module itself and the `run` command integration are solid foundations — what's needed is to finish the `_log_router_decision` function, wire in the REPL, refactor the Slack triage to share code, and add CLI-level integration tests. Ship the audit logging fix first since it's blocking the existing code from running at all.
