Read and use the Expo / React Native in-app developer tools: the developer menu (reload, go home, performance monitor, element inspector, Open DevTools, and fast refresh) and React Native DevTools (Console, Sources, Network, Memory, Performance, Components, and Profiler), plus Rozenite plugins. The tools are identical on iOS and Android; only the gesture that opens the menu differs, so this skill is the shared home referenced by both the iOS-simulator and Android-emulator skills. This is the…
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 Developer Tools (shared iOS + Android) The in-app developer tooling of an Expo / React Native app: the **developer menu** and the **React Native DevTools** it opens. This surface is a React Native feature, so it is the **same on iOS and Android**; the only platform-divergent part is the gesture that opens the menu. That is why this is a shared skill: **ios-simulator** / **expo-ios-simulator** and **android-emulator-harness** each say how to open the menu on their platform, then point here for what the items and panels mean. This skill is the **interpretive field guide**: what each tool shows and how an agent reads it. It is not a driver; driving the app lives in the platform simulator/emulator skills. ## Layout (in the order you meet the tools) 1. `references/opening.md`: the open-gesture matrix (the one platform-divergent thing). 2. `references/dev-menu.md`: the developer-menu items, top to bottom as the app presents them. 3. `references/react-native-devtools.md`: the panels behind "Open DevTools". 4. `references/rozenite.md`: Rozenite plugins, the escape hatch when a built-in panel is not enough. …

How to install
mdr add simiancraft/simiancraft-skills/expo-developer-tools@sha256:9b637fe372e4a069The line at the top of this page pins the label git:20260701.bf690c7, 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.
