What problem does it solve? Upgrading an Expo SDK version often breaks dependencies, deprecated packages, and native configurations. This Skill provides a structured upgrade process with diagnostics, cache clearing, and migration references so the upgrade completes without guesswork. ## Core Features & Use Cases - Step-by-Step Upgrade Workflow: Runs npx expo install expo@latest, npx expo install --fix, and npx expo-doctor diagnostics, then clears caches and reinstalls dependencies. - Breaking Change Migration Guides: Includes references for the New Architecture (SDK 53+), React 19 changes (SDK 54), React Compiler setup, native tabs API changes (SDK 55), and expo-av to expo-audio/expo-video migrations. - Housekeeping and Cleanup: Identifies deprecated packages, removable config files (babel.config.js, metro.config.js), outdated patches, and obsolete expo.install.exclude entries. - Use Case: When upgrading a React Native app from Expo SDK 53 to SDK 55, use this Skill to update dependencies, migrate expo-av audio/video code, convert native tabs components, and enable React Compiler. ## Quick Start Upgrade my Expo app to the latest SDK version and fix any dependency or breaking-change issues.
