Instructions

Step 1: Identify Changed Files

git diff --name-only HEAD
git diff --cached --name-only

Step 2: Analyze Each File

For each changed file:

1. Read the file using Read tool
2. Analyze for issues:
   • Logic errors and bugs
   • Security vulnerabilities (injection, XSS, etc.)
   • Performance problems (N+1 queries, memory leaks)
   • Code duplication
   • Missing error handling
   • Hardcoded values that should be configurable

Step 3: Categorize Issues

Step 4: Check Best Practices

• Functions are small and focused
• Variables have meaningful names
• Error handling is comprehensive
• No commented-out code
• No debug/console statements
• Tests cover new functionality

Step 5: Security Checklist

• No hardcoded secrets/credentials
• Input validation present
• SQL/NoSQL injection prevention
