概要
This skill provides a comprehensive framework for managing application state across different layers of the frontend stack. It enables Claude to architect scalable data flows by categorizing state into server, client, form, and URL types. By providing battle-tested patterns for libraries like TanStack Query, Zustand, and Jotai, the skill ensures that developers can implement complex features like optimistic updates, type-safe URL synchronization, and efficient SSR hydration while maintaining high performance and code maintainability.
