Use when shipping a React Native app with Expo — EAS Build/Submit/Update, eas.json profiles and channels, config plugins, prebuild/CNG, runtime-version policy, OTA updates that never land, SDK upgrades, the New Architecture. NOT RN UI, navigation or native-module authoring (that is `react-native`), NOT a Dart app (that is `flutter`).
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
# Expo & EAS: shipping React Native **Hand-off — the app vs its motion.** This skill owns the Expo platform: router, config plugins, EAS, native modules, store builds. **Animation and gestures** — Reanimated worklets, the UI runtime, sheets, screen transitions, press feedback, haptics, motion that stutters on a real device — are `../motion-craft/SKILL.md`'s. ## What this skill owns Expo is the toolchain and **EAS cloud platform** layered on React Native: cloud builds, store submission, over-the-air JS updates, and **native configuration declared in JavaScript** instead of hand-edited Xcode/Gradle projects. This skill owns the *shipping pipeline* and *native-config-via-JS*. The verb rule of thumb: if the verb is **build / submit / update / prebuild / plugin / EAS / channel / runtime-version**, you are in `expo`. If it is **render / navigate / animate / bridge / write a native module**, route to `react-native`. Other exits: web React/hooks/state → `react`, a Dart app → `flutter`, native-only Swift/Kotlin → `swift-ios`/`kotlin-android`, a desktop wrapper → `tauri`/`electron`, CI unrelated to EAS → `github-actions`. …

How to install
mdr add ericrisco/rsc-harness/expo@sha256:a84ec630b11a4e63The line at the top of this page pins the label git:20260901.09d08c9, 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.
