Is it compatible with Fastify v5?

Yes, the skill follows the latest Fastify v5 requirements, such as using full JSON Schema definitions via Type.Object for all route schemas.

Does it support authentication and authorization?

Yes, it provides implementation patterns for header-based authentication and custom decorators for role-based permission checks (RBAC).

How does it handle request validation?

It utilizes TypeBox for JSON Schema validation, which provides full TypeScript type inference for request bodies, query strings, and path parameters.

Does this skill support OpenAPI documentation?

Yes, it includes guidelines for adding operationIds, tags, and summaries to routes to ensure high-quality, compatible OpenAPI/Swagger generation.

Can I use this for production-grade error handling?
