# Code Review Pro Deep code analysis covering security, performance, maintainability, and best practices. ## When to Use This Skill Activate when the user: - Asks for a code review - Wants security vulnerability scanning - Needs performance analysis - Asks to "review this code" or "audit this code" - Mentions finding bugs or improvements - Wants refactoring suggestions - Requests best practice validation ## Instructions 1. **Security Analysis (Critical Priority)** - SQL injection vulnerabilities - XSS (cross-site scripting) risks - Authentication/authorization issues - Secrets or credentials in code - Unsafe deserialization - Path traversal vulnerabilities - CSRF protection - Input validation gaps - Insecure cryptography - Dependency vulnerabilities 2. **Performance Analysis** - N+1 query problems - Inefficient algorithms (check Big O complexity) - Memory leaks - Unnecessary re-renders (React/Vue) - Missing indexes (database queries) - Blocking operations - Resource cleanup (file handles, connections) - Caching opportunities - Excessive network calls - Large bundle sizes 3. **Code Quality & Maintainability** - Code duplication (DRY violations) - Function/method length (should be <50 lines) - Cyclomatic complexity - Unclear naming - Missing error handling - Inconsistent style - Missing documentation - Hard-coded values that should be constants - God classes/functions - Tight coupli...
