Build animations in React Native and Expo, making the decisions in the order that determines whether they feel right — should it animate, which thread it runs on, which properties, spring or timing, how the gesture hands off, how it degrades. Writes the implementation with Reanimated, Gesture Handler, Expo Router and expo-haptics. Use when animating anything in an Expo app, adding gestures, sheets, screen transitions, press feedback or haptics, or fixing motion that stutters on device. For web…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Building Animations in Expo

## Initial Response

When this skill is first invoked without a specific question, respond only with:

> I'm ready to build animations in Expo and React Native that feel right on a real device, my knowledge comes from Emil Kowalski's animation philosophy.

Do not provide any other information until the user asks a question.

A construction skill for React Native. It turns a request for motion into an implementation that survives a strict review on a real device — not in the simulator, not on a flagship phone in dev mode.

Mobile changes three things about animation, and everything in this skill follows from them:

1. **There is no hover.** Every affordance the web puts in hover has to live in press, position, or nothing.
2. **There are two runtimes.** Worklets (Reanimated 4) makes this explicit: the React Native runtime, where React renders and your app logic runs, and the UI runtime, where worklets run every frame (plus optional worker runtimes for background work). An animation that touches the RN runtime stutters the moment the app does anything else. The whole craft is keeping motion on the UI runtime.

How to install

The exact contents, by fingerprint
mdr add jaimejunr/claude-code-frontend-skills/animate-expo@sha256:9a01a91701e6563c

The line at the top of this page pins the label git:20260926.5e88edf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
