Automated API Documentation Generator

Auto-generate API reference documentation: $ARGUMENTS

Current API Infrastructure

• Code annotations: !grep -r "@api\|@swagger\|@doc" src/ 2>/dev/null | wc -l annotations found
• API framework: @package.json or detect from imports
• Existing specs: !find . -name "spec.yaml" -o -name "spec.json" | head -3
• Documentation tools: !grep -E "swagger|redoc|postman" package.json 2>/dev/null || echo "None detected"
• CI/CD pipeline: @.github/workflows/ (if exists)

Task
