Designing a RESTful API using OpenAPI 3.1 involves structuring your document with clear endpoint definitions, request/response schemas, and security definitions. This Skill provides best practices for API contract definition, schema composition, and versioning to ensure maintainable, well-documented RESTful APIs.

The best way to generate server stubs and client SDKs from an OpenAPI specification is using openapi-generator. This Skill facilitates code generation by validating your API contract first, ensuring the generated server stubs and client libraries accurately reflect your defined endpoints and schemas.

Schema composition in Swagger uses allOf, oneOf, and anyOf to build reusable and polymorphic schemas. This Skill leverages these keywords to help you structure complex OpenAPI documents, combining multiple schema definitions to handle diverse response payloads and request bodies effectively.

Yes, OpenAPI validation catches breaking changes in your API contract early through linting techniques. This Skill offers validation methods to identify errors and breaking modifications before deployment, ensuring your RESTful API specifications remain consistent and clear throughout the development lifecycle.

Both OpenAPI 3.0 and 3.1 standards are supported for structuring a user management REST API. This Skill provides design guidance for both versions, helping you define endpoints, request/response schemas, and security definitions while adhering to the appropriate OpenAPI best practices.

OpenAPI $ref references may fail to resolve during code generation due to incorrect schema composition or circular dependencies. This Skill provides best practices for leveraging $ref alongside allOf, oneOf, and anyOf, ensuring your reusable schemas validate properly before generating server stubs.
