Code Review

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.
