Code Review

Comprehensive security and quality review of uncommitted changes:

1. Get changed files: git diff --name-only HEAD

2. For each changed file, check for:

Security Issues (CRITICAL):

• Hardcoded credentials, API keys, tokens
• SQL injection vulnerabilities
• XSS vulnerabilities
• Missing input validation
• Insecure dependencies
• Path traversal risks

Code Quality (HIGH):

• Functions > 50 lines
• Files > 800 lines
• Nesting depth > 4 levels
• Missing error handling
• console.log statements
• TODO/FIXME comments
• Missing JSDoc for public APIs

Best Practices (MEDIUM):

• Mutation patterns (use immutable instead)
• Emoji usage in code/comments
• Missing tests for new code
• Accessibility issues (a11y)

3. Generate report with:

   • Severity: CRITICAL, HIGH, MEDIUM, LOW
   • File location and line numbers
   • Issue description
   • Suggested fix

4. Block commit if CRITICAL or HIGH issues found

Never approve code with security vulnerabilities!
