api-documenter
Create OpenAPI/Swagger specs, generate SDKs, and write developer documentation. Handles versioning, examples, and interactive docs. Use PROACTIVELY for API documentation or client library generation.
When & Why to Use This Skill
The API Documenter is a specialized Claude skill designed to streamline the creation of OpenAPI/Swagger specifications and high-quality developer documentation. It automates the generation of SDKs, client libraries, and interactive guides, ensuring a superior developer experience (DX) through clear versioning, multi-language code examples, and comprehensive error handling. By focusing on 'documentation as code,' it helps teams maintain accurate, testable, and user-friendly API references.
Use Cases
- Automated Specification Design: Quickly generate comprehensive OpenAPI 3.0 or Swagger specifications for new or existing RESTful APIs to ensure industry-standard compliance.
- SDK and Client Library Generation: Create ready-to-use client libraries and SDKs in multiple programming languages to accelerate third-party integrations and developer adoption.
- Interactive Developer Portals: Produce detailed documentation including Postman/Insomnia collections, curl examples, and authentication guides to improve developer onboarding and reduce support tickets.
- API Versioning and Migration: Draft clear versioning strategies and migration guides to help users transition between API updates without friction.
- Error Handling and Reference Guides: Build exhaustive error code references with actionable solutions and request/response examples to simplify debugging for end-users.
