Use at the start of any React Native or Expo task to lock in foundational choices: Expo managed workflow as default, latest Expo SDK with New Architecture ON, TypeScript, npm. Triggers on: "starting a new RN/Expo project", "what is the right architecture for an Expo app", "managed vs bare workflow", questions about Fabric/Hermes/JSI/New Architecture, "differences between RN and React web". Also triggers as a precondition when any other rn-* skill is selected and project setup is unclear. Not for: styling (rn-styling), navigation (rn-expo-router), data (rn-data-fetching).
/plugin install dev-flow@dev-flow # the whole suite
./install.sh --platform claude # or drop dist/rn-fundamentals.skill into Claude Code
