SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Manually writing and maintaining API documentation is time-consuming, often falls out of sync with code, and lacks standardization, leading to confusion for API consumers.

Core Features & Use Cases

  • OpenAPI 3.0 Snippets: Generates standardized OpenAPI/Swagger YAML/JSON snippets for REST API endpoints.
  • Comprehensive Details: Includes path, method, summary, request/response schemas, parameters, and authentication requirements.
  • Use Case: You've just created a new POST /api/auth/login endpoint. This skill generates the complete OpenAPI specification for it, including request body schema, success and error responses, making your API self-documenting.

Quick Start

Use the api-documentation-generator skill to document the GET /api/products/{id} endpoint, including its parameters and response schema.

FAQPage Schema
How do I generate OpenAPI documentation for my REST API endpoints?

OpenAPI documentation generation converts your REST API endpoint definitions into standardized OpenAPI 3.0 YAML or JSON specs. This Skill produces complete endpoint documentation including paths, methods, request/response schemas, parameters, and authentication details, eliminating manual spec writing and keeping documentation in sync with your API design.

What does OpenAPI/Swagger documentation include?

OpenAPI specifications generated by this Skill contain endpoint paths, HTTP methods, operation summaries, request body schemas, response schemas with status codes, parameter definitions, and security scheme requirements. This standardized format enables API consumers to understand endpoints, parameters, and authentication without reading separate docs.

Can I use this to document endpoints with authentication requirements?

Yes. This Skill generates OpenAPI 3.0 compliant documentation that includes security schemes and authentication requirements alongside endpoint paths, methods, and response schemas. Your API consumers get complete integration guidance with auth details built into the spec.

How do I keep API documentation synchronized with my endpoint changes?

By regenerating OpenAPI documentation whenever REST API endpoints change, you eliminate drift between code and docs. This Skill transforms endpoint definitions into standardized OpenAPI YAML/JSON specs, ensuring documentation reflects current endpoint structure, parameters, and responses.

Does this generate documentation for REST APIs only, or other API types?

This Skill focuses on REST API endpoint documentation using OpenAPI 3.0 standards. It generates YAML/JSON specifications for REST endpoints with standard HTTP methods, request/response bodies, status codes, and security schemes specific to REST architecture.

What's the fastest way to document a new API endpoint?

Provide your endpoint definition—path, method, parameters, request schema, and response schema—to this Skill. It generates complete OpenAPI 3.0 documentation including summaries, authentication requirements, and status codes, eliminating manual YAML/JSON authoring and formatting errors.
