Can I use this with existing codebases?

Absolutely. The skill includes patterns for the 'Code-First' and 'Hybrid' approaches, allowing you to generate or annotate specs based on existing API implementations.

Does this skill support the latest OpenAPI standards?

Yes, it is specifically designed to leverage the OpenAPI 3.1.0 standard, including advanced JSON Schema features and improved documentation capabilities.

Is this skill suitable for complex security requirements?

Yes, it provides implementation patterns for various security schemes, including Bearer tokens, API keys, and complex OAuth2 scopes.

Does it provide templates for common API components?

Yes, it includes robust templates for complete specifications, common response types (like 404 and 429), authentication schemas, and pagination patterns.

How does this improve API reliability?

By establishing a clear API contract, the skill helps you validate that your code implementation matches your documentation, reducing integration errors for end-users.
