LABSCO SUMMARY

Summary

Voltra's single skill teaches an agent to write, review, and debug Voltra's React Native JSX for iOS Live Activities and Android widgets, in place of native Swift or Kotlin.

The one skill, named voltra, covers the whole surface a developer touches: the JSX components and hooks (useLiveActivity and friends), the Expo config plugin that wires up native extension targets, and the Voltra CLI. Under the hood the library compiles that JSX to SwiftUI for iOS Live Activities and Dynamic Island layouts, and to Jetpack Compose Glance for Android home-screen widgets, and it also covers the push-update side — ActivityKit tokens on iOS and FCM on Android — for updating a running activity from a server.

This is for a React Native or Expo team that already wants Live Activities, Dynamic Island layouts, or Android widgets and would rather write them in React than learn SwiftUI and Compose Glance directly. It is not for a project still on Expo Go: the README states plainly that Voltra is not supported there, and using it means installing the platform-specific client packages, adding the Expo plugins to app.json, and running expo prebuild --clean to generate real native targets — Xcode and Android Studio still have to be installed even though you never open them to write UI code.

READ MORE

One skill, one narrow job.

There is nothing else in this package — no companion skill for testing, migration, or troubleshooting build failures — so the whole value of installing it rests on this single guide staying accurate as Voltra's API changes.

Where it sits organizationally.

Voltra lives under the callstackincubator GitHub org rather than Callstack's main namespace, and the README credits two named individuals as its authors — signals worth weighing if you need a package with a broader maintenance base behind it.
