/coach - Adversarial Implementation Review
Usage
/coach [requirements-file]
/coach - Infer requirements from context/coach requirements.md - Validate against specific file
Coach-Player Loop
You orchestrate this dialectical loop between implementing agent (player) and reviewer (coach):
- You (player) implement features
/coach invokes adversarial review with independent evaluation of compliance to requirements- Coach returns:
IMPLEMENTATION_APPROVED or specific fixes
- Address feedback, loop until approved
Review Process
Step 1: Identify Requirements
Check (in order):
- Specified requirements file or issue/ticket mentioned
requirements.md, REQUIREMENTS.md, SPEC.md, TODO.md- Conversation context; ask user if nothing found
Step 2: Adversarial Review
Review with fresh objectivity - discard prior knowledge, don't rationalize shortcuts.
| Check Category | Items |
|---|
| Requirements | Each item: implemented or missing with specific gap |
| Compilation | Compiles? Tests pass? Runs? |
| Common Gaps | Auth on endpoints, token refresh endpoint, HTTPS, bcrypt for passwords, error handling, input validation |
| Functional | Test actual flows (not just compilation), verify edge cases work |
| Test Coverage | Auth error cases (401/403), token expiry, invalid inputs, rate limits |
Step 3: Return Verdict
If approved (>95% complete):
IMPLEMENTATION_APPROVED
- [Requirement 1]: Verified
- [Requirement 2]: Verified
- Compilation: Success
- Tests: All passing
If fixes needed:
REQUIREMENTS COMPLIANCE:
- [Requirement]: Implemented
- [Requirement]: Missing - [specific gap]
IMMEDIATE ACTIONS NEEDED:
1. [Specific fix with file/line if known]
2. [Specific fix]
Key Principles
Rigorous but fair:
- Catch real gaps (security, logic, data flow), not style preferences
- Functionality over aesthetics; always flag security issues (auth, crypto, validation)
Concise:
- Bullets, not essays; specific issues, not vague concerns
- No file contents or verbose analysis in output
Fresh context is your superpower:
- Review as if you've never seen this code; validate against requirements, not intentions
Magic Signal
IMPLEMENTATION_APPROVED = termination signal
Only use when: all requirements met, code compiles/runs, tests pass, no significant gaps.
If in doubt, don't approve.
Minimal Example
User: /coach SPEC.md
Claude:
REQUIREMENTS COMPLIANCE:
- User registration endpoint (bcrypt hashing)
- Login with JWT tokens
- Logout endpoint - not implemented
- Token refresh - missing /auth/refresh endpoint
IMMEDIATE ACTIONS NEEDED:
1. Add POST /auth/logout endpoint
2. Add POST /auth/refresh for token renewal
3. Add tests for 401 on expired tokens
---
User: [fixes] /coach SPEC.md
Claude:
IMPLEMENTATION_APPROVED
- All auth endpoints verified (register, login, logout, refresh)
- 18 tests passing including auth error cases
