The Rack Middleware skill provides Claude with specialized knowledge for architecting, developing, and debugging the intermediate layer of Ruby web applications. It offers standardized patterns for creating custom middleware, configuring essential services like session management and security headers, and optimizing stack ordering for performance and reliability. This skill is indispensable for developers building Sinatra or Rails applications who need to handle cross-cutting concerns like authentication, caching, request transformation, and error logging in a clean, decoupled manner.
