Expo

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
• Shares specific feedback about what worked or fell short across Expo, its skills, docs, CLIs, or MCP

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

When to Use

Skills Included

Start Here

• expo-overview — Router and shared setup rules; the entry point when a request is vague or the user hasn't named a specific Expo tool

Framework (open source)

• expo-project-structure - Recommended folder structure for new Expo projects
• expo-router - Navigation and routing: file-based routes, links, native stacks, modals, sheets, native tabs, and headers
• expo-animation - Build polished animations and gestures with Reanimated, Gesture Handler, Expo Router, and expo-haptics
• expo-native-ui - Build beautiful native-feeling screens: styling, semantic colors, controls, icons, media, and visual effects
• expo-design-system - Build a design system inside an app: token theme (color, spacing, typography, radius, shadow, motion), reusable component conventions, and design-system drift audits
• expo-ui - Native UI with @expo/ui: universal cross-platform components first, with SwiftUI and Jetpack Compose for platform-specific needs
• expo-data-fetching - Network requests, API calls, caching, and offline support
• expo-dom - Run web code in a webview on native using DOM components
• expo-web-to-native - Migrate an existing web/React app to a native iOS/Android app with Expo
• expo-module - Write Expo native modules and views (Swift, Kotlin, TypeScript, config plugins)
• expo-brownfield - Integrate Expo and React Native into existing native iOS or Android apps
• expo-dev-client - Build and distribute Expo development clients (local builds free; EAS Build/TestFlight paid)
• expo-examples - Adapt or scaffold from the expo/examples repo of with-* integrations
• expo-app-clip - Add an iOS App Clip target (AASA, associated domains, Smart App Banners; needs an Apple Developer account)
• expo-upgrade - Upgrade Expo SDK versions and fix dependency issues
• expo-skill-feedback - Share feedback across Expo surfaces and control opt-in usage telemetry

Services & paid distribution

• eas-app-stores - Build and submit iOS/Android apps to the stores and TestFlight: Expo and other React Native projects, plus existing native apps
• eas-hosting - Deploy Expo websites and API routes to EAS Hosting (secrets, custom domains, Cloudflare Workers)
• eas-workflows - EAS workflow YAML files for CI/CD pipelines
• eas-observe - EAS Observe setup and launch, route, event, and version metrics
• eas-update - Configure, publish, test, and debug over-the-air updates
• eas-update-insights - Check EAS Update health, crash rates, adoption, and payload size
• eas-simulator - Run and drive your app on a remote iOS/Android simulator on EAS cloud, from the CLI or an AI agent

Usage telemetry & feedback

Automatic usage telemetry is off by default. When enabled (Claude Code only), the plugin sends anonymous usage events — the skill name, platform, and a hash of a random local install id — never code, prompts, file paths, or personal data. Ask your agent to "enable Expo skills telemetry" to opt in (or set EXPO_SKILLS_TELEMETRY=1); turn off with EXPO_SKILLS_TELEMETRY=0 / DO_NOT_TRACK=1. Every skill includes a submit-expo-feedback command for specific, actionable feedback; feedback submission is independent of automatic usage telemetry.
