Git PR Reviewer

Instructions

When reviewing a pull request:

1. Get the diff: Run git diff main...HEAD or git diff <base-branch>...HEAD
2. Analyze changed files: Identify all modified, added, and deleted files
3. Review each file for:
   • Logic errors and bugs
   • Security vulnerabilities (SQL injection, XSS, hardcoded secrets)
   • Performance issues (N+1 queries, unnecessary re-renders, memory leaks)
   • Code style and consistency
   • Missing error handling
   • Test coverage gaps

Review Checklist

• Proper error handling
• No unused imports or dead code

Performance

• No memory leaks

Testing

• New code has tests
• Edge cases covered
