WHY WE STOPPED USING SDKS

Summary from the TLDR newsletter

SDKs are supposed to save developers time, but AI has changed the cost curve. Integrating with an SDK is often as much work as calling the HTTP API directly. It is now cheap to write a tailored REST client for exactly the endpoints developers need to use while providing better unified observability. Instead of shipping SDKs, companies will likely start shipping agent skills that teach agents how to call the API correctly, reuse the right patterns, and avoid pushing every runtime call through a vendor package.
