API Development Skills Pack for Claude Code

The API Development Skills Pack accelerates your API development workflow in Claude Code with four focused skills and the /api slash command. Build production-ready REST and GraphQL APIs with proper authentication, comprehensive testing, and auto-generated documentation in a fraction of the usual time.

What You Get

• REST/GraphQL Design Skill — Scaffolds complete API endpoints or GraphQL schemas with proper resource naming, versioning, pagination, filtering, and error response formats following industry standards
• Auth Implementation Skill — Adds authentication and authorization to your APIs including JWT tokens, OAuth 2.0 flows, API key management, rate limiting, and role-based access control middleware
• API Testing Skill — Generates comprehensive API test suites with request validation, response schema checks, authentication flow tests, error handling verification, and load testing scripts
• API Documentation Skill — Produces OpenAPI/Swagger specs, Postman collections, and interactive API documentation pages directly from your route definitions and type annotations
