What problem does it solve? Writing long-form technical documentation for a complex codebase is time-consuming and often skipped, leaving teams without architecture references, onboarding material, or design rationale. This Skill analyzes an existing codebase and produces structured, in-depth technical manuals that capture both the what and the why of the system. ## Core Features & Use Cases - Codebase Analysis: Examines code structure, dependencies, design patterns, data flows, and integration points to ground documentation in the actual implementation. - Structured Long-Form Output: Produces multi-chapter documents covering executive summaries, architecture overviews, design decisions, core components, data models, security, and deployment. - Diagram and Visual Planning: Describes architectural diagrams, sequence diagrams, and flowcharts to communicate system behavior. - Use Case: Point the Skill at a backend service repository and receive a complete architecture guide with component deep-dives, API documentation, and onboarding reading paths for new engineers. ## Quick Start Analyze this repository and generate a comprehensive technical architecture document covering its components, data flow, and design decisions.
