Generate API documentation from route definitions and handlers.

Steps

  1. Detect the web framework in use (Express, Fastify, FastAPI, Gin, Actix, etc.).
  2. Scan for route definitions:
    • Express/Fastify: app.get(), router.post(), route files.
    • FastAPI: @app.get(), @router.post() decorators.
    • Go: http.HandleFunc(), gin route groups.
  3. For each endpoint, extract:
    • HTTP method and path (including path parameters).
    • Request body schema from TypeScript types, Pydantic models, or struct tags.
    • Query parameters and their types.
    • Response format from return types or response calls.
    • Authentication requirements from middleware.
    • Rate limiting or other middleware constraints.
  4. Generate documentation in the specified format (OpenAPI/Swagger, Markdown, or both).
  5. Include request/response examples with realistic data.
  6. Write the output to docs/api/ or the specified location.

Format

## <METHOD> <path>

<Description>

**Auth**: Required | Public
**Rate Limit**: <limit>

### Parameters
| Name | In | Type | Required | Description |
|------|-----|------|----------|-------------|

### Request Body
```json
{ "example": "value" }

Response (200)

{ "example": "response" }

## Rules

- Document every public endpoint; skip internal-only routes.
- Include error responses (400, 401, 403, 404, 500) with example bodies.
- Use actual TypeScript/Python types for schemas, not generic `object` or `any`.
- Keep examples realistic and consistent across related endpoints.
- Note deprecated endpoints clearly with migration guidance.
