What problem does it solve? Writing and maintaining accurate technical documentation is time-consuming, and undocumented code slows onboarding and API adoption. This Skill automates the creation of docstrings, API specifications, documentation sites, and user guides while validating that every code example actually compiles or runs. ## Core Features & Use Cases - Inline Documentation: Generates Google, NumPy, or Sphinx style Python docstrings and JSDoc annotations for TypeScript/JavaScript functions, classes, and interfaces. - API Documentation: Produces OpenAPI 3.0/3.1 specs and framework-specific docs for FastAPI, Django REST Framework, NestJS, and Express, plus GraphQL, AsyncAPI, and gRPC documentation. - Doc Sites & Guides: Configures documentation portals with Docusaurus, MkDocs, or VitePress, and writes tutorials, troubleshooting guides, and FAQs. - Use Case: Point it at an undocumented NestJS backend and receive fully decorated controllers with @ApiOperation/@ApiResponse annotations, a validated Swagger UI setup, and a coverage report showing before/after documentation percentages. ## Quick Start Ask the assistant to document all public functions in your project using Google-style docstrings and generate a coverage report.
