Standardizes ASP.NET Core API responses using correct IActionResult methods and RFC 9457 error formatting.
This skill provides domain-specific guidance for C# developers using ASP.NET Core to ensure their APIs adhere to RESTful best practices and industry standards. It helps Claude correctly implement HTTP status codes—such as 201 Created with Location headers and 204 No Content for deletions—while enforcing a unified error response format through ProblemDetails (RFC 9457). By integrating these patterns, developers can improve API consistency, simplify client-side error handling, and maintain cleaner controllers by delegating exception management to global handlers.
