What problem does it solve?
Manually creating consistent, valid OpenAPI 3.1 REST API contracts is time-consuming and error-prone, especially for teams that need to align on entity models, endpoint designs, and standard error shapes across services.
Core Features & Use Cases
- Guided Conversational Workflow: Walks users through 6 structured phases from initial service idea to production-ready schema, including entity discovery, CRUD endpoint design, and iterative refinement.
- Built-in Best Practices: Enforces standard pagination envelopes, RFC 7807 problem details for errors, reusable $ref components, and support for common authentication and API versioning patterns.
- Use Case: A backend developer building a new task management API can use this skill to define User and Project entities, design CRUD and custom endpoints, and generate a fully valid OpenAPI 3.1 spec ready for client code generation and mock server setup.
Quick Start
Use the openapi-schema-creator skill to design a complete OpenAPI 3.1 schema for a file sharing API with user, folder, and file entities.
