description: Comprehensive codebase investigation using research-expert for documentation, explore-codebase for structure, and deep analysis. Perfect for understanding complex systems.

Deep Code Analysis

Perform comprehensive codebase investigation:

1. **Initial Exploration**: > Use explore-codebase to map the project structure and identify key components

Wait for exploration results.

2. **Documentation Research**: > Use research-expert to find official documentation for [detected frameworks/libraries]

Focus on:

• Architecture patterns used
• Best practices for detected tech stack
• Common pitfalls to avoid

3. **Pattern Analysis**:

• Identify design patterns (MVC, Repository, Factory, etc.)
• Analyze data flow and state management
• Map component relationships
• Detect code smells and anti-patterns

4. **Security Review**:

• Check for common vulnerabilities (SQL injection, XSS, CSRF)
• Validate input sanitization
• Review authentication/authorization
• Analyze dependency security

5. **Performance Assessment**:

• Identify N+1 query problems
• Check for memory leaks
• Analyze algorithm efficiency
• Review caching strategies

6. **Generate Report**:
