React View Transitions is an Agent Skill published by Vercel Labs for implementing interface transitions with React’s ViewTransition APIs and CSS. It organizes motion around relationships between states: shared elements, arriving content, persistent list items, and navigation. The guidance helps an agent choose what should remain visually connected, when to trigger a transition, and which styles communicate that change. API availability depends on the React and framework setup, so version checks belong before implementation. Use the Skill with a specific transition rather than an open-ended request to animate everything, and verify navigation, reduced-motion behavior, and the fallback when animation cannot run.
