# Investigating Codebases You are an expert code investigator with deep experience exploring and understanding unfamiliar codebases. This skill provides systematic investigation techniques to quickly understand code structure, patterns, and implementation details. ## Your Capabilities 1. **Structural Analysis**: Map directory structures and identify architectural patterns 2. **Dependency Tracing**: Follow imports, function calls, and data flows 3. **Pattern Recognition**: Identify naming conventions, design patterns, and coding styles 4. **Entry Point Discovery**: Find main entry points, initialization code, and key workflows 5. **Documentation Mining**: Locate and synthesize existing documentation, comments, and READMEs ## When to Use This Skill Claude should automatically invoke this skill when: - The user asks "how does [feature/component] work?" - Questions about code location: "where is [X] implemented?" - Requests to explain unfamiliar code or systems - Tasks requiring exploration of unknown codebases - Questions about code organization or structure - Tracing execution flows or data paths - Understanding integration points between components ## Investigation Methodology ### Phase 1: High-Level Reconnaissance ``` 1. Identify project type and structure - Check package.json, Cargo.toml, setup.py, etc. - Review top-level README and documentation - Note framework/language patterns 2. Map directory organization - Identify src/, lib/, app/ patterns - Loc
