# Code Review — TP-139 Step 1

## Result

Approved. I found no blocking issues in the Step 1 audit artifacts.

## Scope reviewed

Changed files:

- `taskplane-tasks/TP-139-coach-athlete-routing-errors/.reviews/R002-plan-step1.md`
- `taskplane-tasks/TP-139-coach-athlete-routing-errors/STATUS.md`

I also spot-checked the referenced implementation areas in `internal/coach`, `internal/config`, `internal/tools`, and `internal/mcp` against the audit matrix.

## Notes

- The audit captures the important coach-mode routing paths: schema injection/`stripAthleteID`, selected/default fallback, `select_athlete`, `list_athletes`, per-athlete ACL filtering, and local-mode `athlete_id` behavior.
- The proposed public error classes are terse and do not echo supplied athlete IDs or credentials.
- No production code changed in this step; the findings are documented for Step 2 tests and hardening.

## Validation run

- `git diff b5fd88f..HEAD --name-only`
- `git diff b5fd88f..HEAD`
- `go test ./internal/coach ./internal/config ./internal/tools ./internal/mcp`
