Using the Claude app rather than Claude Code? You can add a skill there too. How to add it in the app
What does expo-dev-client do?
expo-dev-client is a Claude skill that helps Claude make Expo development builds, the custom version of Expo Go that your own native code needs. It lists when you need one: local Expo modules, widgets or app clips, native modules missing from Expo Go, config plugins, or testing push notifications and universal links. Claude checks that eas.json has a development profile, then runs eas build -p ios --profile development --submit for TestFlight, or adds --local to build on your machine. It covers installing the .app, .ipa or .apk with xcrun simctl, ideviceinstaller or adb, connecting through npx expo start --dev-client, and fixing signing errors with eas credentials.
When should you use expo-dev-client?
Use it when
- Your app uses native modules that Expo Go lacks
- Sharing a test build with your team through TestFlight
- Building an iOS or Android dev client on your own machine
Skip it when
- Expo Go already runs your app
- You are submitting a production release to the app stores
