# Code Review Skill

- Review code for correctness, bugs, security issues, performance, and maintainability.
- Understand the existing architecture and conventions before judging or changing code.
- Prioritize real problems over style preferences.
- Check edge cases, error handling, null/undefined handling, and race conditions.
- Look for unnecessary complexity, duplicated logic, and dead code.
- Check API contracts, data flow, state management, and side effects.
- Identify potential performance problems and unnecessary re-renders.
- Check TypeScript type safety and unsafe assumptions.
- Check React hooks, dependencies, component lifecycle, and rendering behavior when applicable.
- Check accessibility and user-facing behavior when applicable.
- Do not suggest changes that are purely subjective unless they improve consistency or readability.
- Prefer minimal, practical fixes over large refactors.
- Clearly explain each finding with the problem, impact, and recommended fix.
- Rank findings by severity: critical, high, medium, low.
- If the code is correct, say so instead of inventing issues.
