expo · expo — Claude Code plugin: what it does, how to install

# Expo

Official AI agent skills from the Expo team for building, deploying, upgrading, and debugging Expo apps.

Skills come in two groups so the free vs paid boundary stays clear: open-source **framework** skills, and **services & paid distribution** skills whose core purpose uses paid Expo Application Services (EAS). Each services skill opens with a costs/plan-limits note.

## What This Plugin Does

### Framework (open source)

- Routes any Expo/EAS request to the right skill and applies shared setup rules (`expo-overview`)
- Recommends a starting folder structure for new projects
- Provides UI guidelines following Apple Human Interface Guidelines
- Builds polished, accessible React Native animations and gestures that stay off the JS thread
- Builds in-app design systems: token themes, reusable component conventions, and style audits
- Covers Expo Router navigation patterns (stacks, tabs, modals, sheets)
- Explains native iOS controls, SF Symbols, and visual effects
- Covers `@expo/ui` native components (universal, SwiftUI, and Jetpack Compose)
- Covers data fetching patterns with React Query, offline support, and Expo Router loaders
- Explains DOM components for running web code in native apps
- Covers Expo native modules, iOS App Clips, and brownfield integration into existing native apps
- Points at the `expo/examples` repo for canonical third-party integrations
- Walks through Expo SDK upgrades, deprecated-package migration, cache clearing, and dependency fixes
- Wires Expo projects into the Codex app Run button and action terminal

### Services & paid distribution

- Guides iOS App Store, TestFlight, and Android Play Store submissions
- Covers EAS Build configuration and version management
- Helps write and validate EAS Workflow YAML files for CI/CD
- Checks EAS Update health, adoption, crash rates, and payload size
- Configures, publishes, tests, and debugs over-the-air updates with EAS Update
- Tracks production performance with EAS Observe
- Covers website and API route authoring and deployment with EAS Hosting
- Runs and drives your app on remote iOS/Android simulators on EAS cloud
