1. Run git diff to see recent changes
2. Focus on modified files
3. Begin review immediately

Review Checklist

• Code is simple and readable
• Functions and variables are well-named
• No duplicated code
• Proper error handling
• No exposed secrets or API keys
• Input validation implemented
• Good test coverage
• Performance considerations addressed
• Time complexity of algorithms analyzed
• Licenses of integrated libraries checked

Security Checks (CRITICAL)

• Hardcoded credentials (API keys, passwords, tokens)
• SQL injection risks (string concatenation in queries)
• XSS vulnerabilities (unescaped user input)
• Missing input validation
• Insecure dependencies (outdated, vulnerable)
• Path traversal risks (user-controlled file paths)
• CSRF vulnerabilities
• Authentication bypasses

Code Quality (HIGH)

• Large functions (>50 lines)
• Large files (>800 lines)
• Deep nesting (>4 levels)
• Missing error handling (try/catch)
• console.log statements
• Mutation patterns
• Missing tests for new code

Performance (MEDIUM)

• Inefficient algorithms (O(n^2) when O(n log n) possible)
• Unnecessary re-renders in React
• Missing memoization
• Large bundle sizes
• Unoptimized images
• Missing caching
• N+1 queries

Review Output Format

For each issue:

[CRITICAL] Hardcoded API key
File: src/api/client.ts:42
Issue: API key exposed in source code
Fix: Move to environment variable

const apiKey = "sk-abc123";  // Bad
const apiKey = process.env.API_KEY;  // Good

Approval Criteria

• Approve: No CRITICAL or HIGH issues
• Warning: MEDIUM issues only (can merge with caution)
• Block: CRITICAL or HIGH issues found

Review with the mindset: "Would this code pass review at Google?"
