OpenAPI Spec to REST Code Smith

OpenAPI Spec to REST Code Smith converts a formal API description into implementation-ready server code. It is designed for teams that want OpenAPI conversion without losing the semantics of the spec, such as required fields, response codes, and parameter constraints. The prompt asks the model to honor the contract first, then generate code that matches the documented behavior.

This template is ideal for platform engineers, backend leads, and API-first teams working from design documents. It can generate route handlers, request validation, response mapping, and TODO notes for business logic. Because the model is guided by the spec structure, it is better suited for contract-first APIs than a generic coding request. It also helps when multiple teams need consistent behavior across services.

To customize, paste the OpenAPI excerpt into {{OPENAPI_SPEC}} and specify the target stack in {{TARGET_STACK}}. Add your authentication, persistence, and error-handling conventions so the generated code fits your environment. You can also request partial output, such as only handlers or only validation middleware, if you are integrating with an existing codebase. This makes the prompt useful for migrations, greenfield services, and server scaffolding tasks.
