Use when writing the JS/TS inside a React Native or Expo app — screens, Expo Router navigation, lists, Reanimated gestures, platform forks, offline state, native modules — or killing jank and render storms. NOT eas build/submit/OTA/config-plugin (that is `expo`), NOT a Dart app (that is `flutter`), NOT web React/DOM (that is `react` or `nextjs`).
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
# React Native (app code) **Hand-off — the app vs its motion.** Animation and gestures in a React Native app — Reanimated worklets on the UI runtime, gesture handoff, sheets, press feedback, haptics — are `../motion-craft/SKILL.md`'s, whose guidance is platform-agnostic and applies to bare React Native as well as Expo. You write the code that runs *inside* the app: render, navigate, animate, list, persist, and author native modules. Mobile is split across two skills by **verb** — run the verb test before doing anything: | Verb in the request | Skill | |---|---| | render / navigate / animate / list / persist / author-native-module / debug-runtime | **react-native** (here) | | build / submit / update (OTA) / prebuild / config-plugin / `eas.json` / channel / runtime-version | **`../expo/SKILL.md`** | Assume the **New Architecture is on** (Fabric + Turbo Modules). It is mandatory from RN 0.82 / Expo SDK 55 — RN 0.82 (2025-10-08) ignores any disable flag, and SDK 55 is New-Arch-only. SDK 54 (RN 0.81) was the last that could opt out. Never write `newArchEnabled: false` to dodge a bug; fix the bug. Why: the flag is a no-op on current versions, so the "fix" silently does nothing. …

How to install
mdr add ericrisco/rsc-harness/react-native@sha256:b3c37d2efc1b34c8The 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.
