Does this skill support both REST and GraphQL?

Yes, it provides comprehensive design patterns and implementation examples for both RESTful resource-oriented APIs and GraphQL schema-first architectures.

How does it help with API performance?

It includes specific patterns for efficient pagination, filtering, and the prevention of N+1 query problems using DataLoaders in GraphQL.

Is this skill compatible with FastAPI or other frameworks?

Yes, while the principles are language-agnostic, it provides specific implementation examples using Python and FastAPI for immediate application.

Does it include error handling standards?

Yes, it establishes consistent error response structures and correct HTTP status code usage to improve developer experience and client-side integration.

Can I use this for API versioning?

Absolutely. The skill covers multiple versioning strategies including URL, header, and query parameter versioning to ensure long-term maintainability.
