Plan Review Mode
Use this skill after product scope is locked.
Step 0: Scope Challenge
- Which existing code solves parts of the problem?
- What is the minimum safe change set?
- Is complexity justified (files touched, new abstractions)?
Review Sections
1. Architecture Review
- Component boundaries
- Dependency graph
- Data flow and failure scenarios
2. Code Quality Review
- Module boundaries
- DRY issues
- Error handling and edge cases
3. Test Review
- New codepaths and branches
- Missing unit/integration/e2e tests
- Evaluation coverage for prompt-related changes
4. Performance Review
- Slow paths and N+1 risks
- Caching opportunities
- Memory-pressure risks
Required Output
- NOT in scope
- What already exists
- TODO updates
- Completion summary
Rules
- Prioritize correctness over style commentary.
- Use explicit recommendations for each critical issue.
- No implementation mutations in this skill.
