Generate comprehensive API documentation from source code.
Quick Reference
| Task | Resource |
|------|----------|
| Identify framework | See PATTERNS.md |
| Documentation standards | See STANDARDS.md |
| Example outputs | See EXAMPLES.md |
Process
Step 1: Identify API Endpoints
Look for route definitions. For framework-specific patterns, see PATTERNS.md.
Step 2: Extract Information
For each endpoint, extract:
- HTTP method (GET, POST, PUT, DELETE, etc.)
- Path/route
- Parameters (path, query, body)
- Request/response schemas
- Authentication requirements
Step 3: Generate Documentation
Use the template in templates/endpoint.md for each endpoint.
Step 4: Create Overview
Generate an index using templates/index.md.
Output Formats
Markdown (Default)
Generate markdown suitable for README or docs site.
OpenAPI/Swagger
If requested, generate OpenAPI 3.0 spec. See templates/openapi.yaml.
Automation
To auto-detect routes:
python scripts/detect_routes.py <source_directory>
To validate OpenAPI spec:
./scripts/validate_openapi.sh <spec_file>
