Summary
This teaches Claude to write React 19 code the way it's meant to be written now that the React Compiler handles optimization automatically. The main shift is dropping useMemo and useCallback everywhere since the compiler does that work for you. It covers the new patterns like using ref as a regular prop instead of forwardRef, the use() hook for reading promises and conditional context, and knowing when to mark components with "use client" versus keeping them as server components by default. If you're working on a React 19 project and want Claude to stop suggesting the old manual memoization patterns, this is the skill to load.
