Comprehensive code analysis covering security vulnerabilities, performance bottlenecks, maintainability issues, and best practice violations.

• Scans for critical security flaws including SQL injection, XSS, authentication gaps, unsafe deserialization, and credential exposure
• Identifies performance problems such as N+1 queries, inefficient algorithms, memory leaks, and unnecessary re-renders
• Evaluates code quality across duplication, function length, cyclomatic complexity, naming clarity, and error handling
• Provides actionable fixes with before/after code examples, severity prioritization, and explanations of why changes matter
• Covers language-specific idioms, framework conventions, SOLID principles, design patterns, and testing approaches
