What is the primary benefit of the Koan API Building skill?

It eliminates boilerplate code by automatically generating standard CRUD endpoints for any entity using the EntityController base class.

Can I add non-CRUD endpoints to my controllers?

Absolutely. The skill is designed to help you extend the base EntityController with custom HTTP methods for specific business logic and complex queries.

Can I customize the API responses with this skill?

Yes, it provides guidance on using Payload Transformers (IPayloadTransformer) to reformat responses, add HATEOAS links, or exclude sensitive fields.

How does this skill handle API security?

The skill provides patterns for applying global or method-level authorization attributes and integrating specific security policies into your controllers.

API Development

Automates RESTful API creation using the Koan framework's EntityController to accelerate backend development and standardize endpoint management.

About

This skill enables Claude to efficiently build and extend REST APIs within the Koan framework by leveraging the EntityController<T> pattern. It streamlines the generation of standard CRUD operations—including GET, POST, PUT, DELETE, and PATCH—while providing structured guidance for implementing custom business logic, sophisticated authentication policies, and payload transformers for precise response formatting. It is specifically designed for developers who want to eliminate boilerplate C# code while maintaining enterprise-grade security and API versioning standards.
