API Design Skills

3 Skills you can install in Claude Code or any other agent.

The Skills take into account your requirements, domain information and API Standards (samples provided to get you going).

They let you be in the loop by first generating user stories that you can inspect and modify. The skill will then generate a complete, valid, standards-based OpenAPI (fka Swagger) file.

It'll optionally run a quality check and give itself feedback until the quality score gets to 100%.

Finally, it can display the API for you in Swagger UI so you can review it for completeness.

I've been designing APIs for 15+ years and this is the right way to do quick, pragmatic, accurate API design.
