SKILL.md
The skill is based on Expo SDK (docs from expo/expo repo), generated at 2026-02-26.
Expo provides tooling and services for React Native: app config and Prebuild (Continuous Native Generation), Expo SDK packages, development builds, EAS Build (cloud builds and internal distribution), and EAS Update (over-the-air JS updates). Use development builds for production apps; Expo Go is a limited playground.
