Pull Request Review

Perform a thorough code review covering quality, security, performance, and maintainability.

Review Checklist

Code Quality

• Naming: clear, descriptive, consistent with codebase conventions
• Functions: single responsibility, reasonable length (<50 lines)
• Error handling: all failure paths covered, no swallowed exceptions
• Types: proper TypeScript/type annotations where applicable
• DRY: no unnecessary duplication
• Dead code: nothing unused or commented out

Security (see also: security-review skill)

• No secrets or credentials in code
• Input validation on all user-facing endpoints
• Parameterized queries (no string concatenation for SQL)
• Proper auth/authz checks

Performance

• N+1 query patterns
• Missing database indexes for new queries
• Unbounded loops or recursive calls
• Large payload responses without pagination
• Missing caching where appropriate

Testing

• New functionality has tests
• Edge cases covered (empty arrays, null, boundaries)
• Tests are deterministic (no timing dependencies)
• Mocks are appropriate (not over-mocked)

Maintainability

• Changes are documented (README, comments for complex logic)
• Breaking changes are noted
• Migration path is clear for schema changes
• Dependencies added are justified
