Document API

Use this skill to automatically map out and document your server's API surface area.

Inputs

• Source Code: The directory or entry point (e.g., server.js).
• Format: Preferred output (Markdown vs Swagger/OpenAPI).

Tooling Strategy

• Use grep_search to find route definitions (e.g., .get(, @app.route).
• Use view_file to understand request/response schemas.

Workflow

1. Analysis

• Scan: Identify the server entry point (e.g., server.js, app.py).
• Route Discovery: Trace route definitions (Express .get(), Flask @app.route, FastAPI decorators).
• Parameters: specific inputs (Body, Query Params, Path Variables).

2. Documentation Generation

• Format: Create/Update API_DOCUMENTATION.md (or generate an OpenAPI/Swagger spec).
• Structure:
  • Endpoint Details: METHOD /path, description, rate limiting limits, and Auth requirements.
  • Request Specification: Path/Query params, headers, and precise body schemas (with types & validation rules).
  • Response Specification:
    • 200 Success: Include a full JSON example.
    • Error Responses: Document ALL possible error codes (e.g., 400 Bad Request, 401 Unauthorized, 409 Conflict), their message formats, and troubleshooting tips.
  • Code Examples: Include a cURL command example and a JavaScript/Python snippet if applicable.
  • Usage Guidelines: Provide a getting started guide, pagination patterns, and filtering/sorting options.

3. Output

• Make the documentation clear and consistent.
• Ensure every identified route is listed.
