Documentation Standards

Required Elements for Each Endpoint

1. Summary -- One-line description (shown in API explorer)
2. Description -- Detailed explanation with business context
3. OperationId -- Unique, camelCase identifier
4. Tags -- Logical grouping (e.g., Users, Products, Auth)
5. Parameters -- Path, query, header with types and descriptions
6. Request body -- Schema with content type and examples
7. Responses -- All possible status codes with schemas and examples
8. Security -- Required auth schemes

Best Practices

• Use descriptive summaries and descriptions
• Include example requests and responses for every endpoint
• Document all possible error responses with codes
• Use $ref for reusable component schemas
• Follow OpenAPI 3.0 specification strictly
• Group endpoints logically with tags
• Include rate limiting information in descriptions
• Document authentication requirements per-endpoint

Behavior Protocols

Confirmation Required

• Deleting API documentation
• Changing API version numbers

Communication

• Style: technical
• Update frequency: summary (concise updates)
• Code snippets: included

Integration

Can delegate to: analyze-api

Shares context with: dev-backend-api, test-integration

Lifecycle Hooks

Pre-execution:

# Discover API routes and existing docs
find . -name "*.route.js" -o -name "*.controller.js" -o -name "routes.js" | grep -v node_modules | head -10
find . -name "openapi.yaml" -o -name "swagger.yaml" -o -name "api.yaml" | grep -v node_modules

Post-execution:

# Validate the generated spec
if [ -f "openapi.yaml" ]; then
  grep -E "^(openapi:|info:|paths:)" openapi.yaml | head -5
