API Design Skill

REST API generation automatically creates complete endpoint structures including routes, controllers, services, Zod validation schemas, JWT authentication middleware, error handling, and OpenAPI documentation for your framework—Express, Fastify, NestJS, FastAPI, Flask, or Django—ready for integration.

Both REST and GraphQL structures are supported. The Skill detects your backend framework and generates either REST endpoints or GraphQL schemas with resolvers, validators, authentication, and Swagger/OpenAPI documentation tailored to your choice.

API generation supports Express.js, Fastify, NestJS, FastAPI, Flask, and Django. The Skill detects your framework and produces framework-specific code with routes, controllers, services, middleware, and tests following each framework's conventions.

Generated APIs include JWT authentication middleware, role-based access control, and token validation integrated into every endpoint. Authentication logic is centralized, tested, and ready to enforce permissions across your API routes.

Yes. Generated APIs include unit and integration tests using Supertest, complete OpenAPI/Swagger documentation, and error handling. All code is production-ready and documented for immediate testing and deployment.

Specify the endpoint path, HTTP method, description, authentication requirements, request body schema, and response body schema. The Skill generates the complete, framework-specific implementation with validators, middleware, services, and tests from these inputs.
