What problem does it solve? Understanding an unfamiliar codebase or diagnosing why a feature behaves unexpectedly requires hours of manual file reading. This Skill automates that investigation by systematically locating entry points, tracing call chains, and producing a structured analysis report. ## Core Features & Use Cases - Four-Phase Investigation Workflow: Locates entry points with Grep/Glob, traces execution paths through Controller/Service/Provider layers, analyzes core logic and data flow, then outputs a formatted report. - Search Pattern Library: Ships a reference guide of ready-made Grep and Glob patterns for finding API endpoints, services, providers, models, and configuration files. - Structured Report Output: Delivers an architecture overview, key files table, execution flow, data flow description, and actionable findings. - Use Case: Ask why an API intermittently returns empty results, and the Skill traces the data retrieval path, identifies fallback and timeout handling, and lists probable causes with recommendations. ## Quick Start Ask the agent to investigate how a specific feature works in this repository and produce an architecture and execution-flow report.
