Android E2e TestingTest Expo Router features on Android emulators using ADB. Use after implementing native Android features or when verifying UI behavior on Android.expo/expo50,418
Deep Code ReviewIn-depth design-focused code review - understands codebase context before evaluating PR changes, posts structured feedback to GitHubexpo/expo50,418
Expo Api DocsWrite TSDoc comments for Expo SDK APIs following official conventions. MUST USE when introducing new user-facing TypeScript APIs in expo-* packages - document APIs correctly from the start, not as an afterthought. Also use when improving existing documentation. Covers @platform, @example, @deprecated, @default annotations, third-person declarative style, blockquote notes, and type export patterns for docs generation.expo/expo50,418
Add App ClipAdd an iOS App Clip target to an Expo app. Use when the user mentions App Clip, AASA, apple-app-site-association, appclips, smart app banner, or wants to ship a lightweight iOS Clip invoked from a URL alongside their parent app.expo/skills2,157
Building Native UiComplete guide for building beautiful apps with Expo Router. Covers fundamentals, styling, components, navigation, animations, patterns, and native tabs.expo/skills2,157
Eas SimulatorRun and control a user's app on a remote iOS/Android simulator hosted on EAS cloud. Always read before executing any `eas simulator:*` commands — it has the current syntax for this experimental API. Use whenever the user needs a simulator they can't run locally — 'run my app on a cloud simulator', 'use eas simulator to run/install/screenshot my app', 'I'm on Linux/Cursor and need an iOS device', 'no sim on this box / headless CI', 'let an agent click through my app and screenshot it', 'test my dexpo/skills2,157
Eas Update InsightsCheck the health of published EAS Updates: crash rates, install/launch counts, unique users, payload size, and the split between embedded and OTA users per channel. Use when the user asks how an update is performing, whether a rollout is healthy, how many users are on the embedded build vs OTA, or wants to gate CI on update health.expo/skills2,157
Expo Api RoutesGuidelines for creating API routes in Expo Router with EAS Hostingexpo/skills2,157
Expo BrownfieldIntegrate Expo and React Native into an existing native iOS or Android app. Use when the user mentions brownfield, embedding React Native in a native app, AAR/XCFramework, or adding Expo to an existing Kotlin/Swift project. Covers both the isolated approach and the integrated approach.expo/skills2,157
Expo Cicd WorkflowsHelps understand and write EAS workflow YAML files for Expo projects. Use this skill when the user asks about CI/CD or workflows in an Expo or EAS context, mentions .eas/workflows/, or wants help with EAS build pipelines or deployment automation.expo/skills2,157
Expo DeploymentDeploy Expo apps to production with EAS — build and submit to the iOS App Store, Google Play Store, and TestFlight, configure eas.json build and submit profiles, manage app versions and build numbers, publish App Store metadata and ASO, and deploy web bundles and API routes via EAS Hosting. Use whenever the user is preparing a production build, running eas build or eas submit, shipping to TestFlight, releasing or rolling out to the app stores, bumping version or build numbers, or setting up storexpo/skills2,157
Expo Dev ClientBuild Expo app for developmentexpo/skills2,157
Expo ExamplesExpo's official example projects — the expo/examples repo of ~70 `with-*` integrations (Stripe, Clerk, Supabase, OpenAI, maps, Reanimated, SQLite, Skia, NativeWind, and more). Use when integrating a third-party library or service into an existing Expo app and you want the canonical, version-matched pattern to adapt, or when scaffolding a new project from one with `npx create-expo --example`.expo/skills2,157
Expo ModuleGuide for creating and writing Expo native modules and views using the Expo Modules API (Swift, Kotlin, TypeScript). Covers module definition DSL, native views, shared objects, config plugins, lifecycle hooks, autolinking, and type system. Use when building or modifying native modules for Expo.expo/skills2,157
Expo ObserveUse for anything related to EAS Observe — adding `expo-observe` to an Expo project (AppMetricsRoot/ObserveRoot HOC, markInteractive, the useObserve hook, and the Expo Router / React Navigation integrations for per-route metrics), querying via the EAS CLI (`eas observe:metrics-summary`, `observe:metrics`, `observe:routes`, `observe:events`, `observe:versions`), or interpreting the resulting metrics (cold/warm launch, TTR, TTI, navigation cold/warm TTR, update download, and the TTI frameRate paramexpo/skills2,157
Expo Skill EvalEvaluate Expo skills in this repo end-to-end - trigger accuracy, generated code quality, and runtime screenshots on iOS simulator and Android emulator via Expo Go (web optional). Use when the user wants to eval an Expo skill, test that a skill produces working code, benchmark a skill with device screenshots, or verify a skill's output renders correctly.expo/skills2,157
Expo Tailwind SetupSet up Tailwind CSS v4 in Expo with react-native-css and NativeWind v5 for universal stylingexpo/skills2,157
Expo UiBuild native UI with the @expo/ui package: real SwiftUI on iOS and Jetpack Compose on Android rendered from React in an Expo or React Native app. Covers universal cross-platform components (Host, Column, Row, Button, Text, List, and more imported from @expo/ui), drop-in replacements for popular React Native community libraries (BottomSheet, DateTimePicker, Slider, Menu, etc.), and platform-specific SwiftUI (@expo/ui/swift-ui, iOS only) and Jetpack Compose (@expo/ui/jetpack-compose, Android only)expo/skills2,157
Native Data FetchingUse when implementing or debugging ANY network request, API call, or data fetching. Covers fetch API, React Query, SWR, error handling, caching, offline support, and Expo Router data loaders (`useLoaderData`).expo/skills2,157
Upgrading ExpoGuidelines for upgrading Expo SDK versions and fixing dependency issuesexpo/skills2,157
Use DomUse Expo DOM components to run web code in a webview on native and as-is on web. Migrate web code to native incrementally.expo/skills2,157
Web To NativeMigrate an existing web React app to a native iOS/Android app with Expo. Use when the user wants to turn a website into a mobile app, port a Next.js/Vite/CRA React codebase to React Native, reuse web code on native incrementally, or asks how web idioms (the DOM, CSS, React Router, localStorage, window) map to native. This is the end-to-end migration guide; use the `use-dom` skill for the DOM-component mechanism itself.expo/skills2,157
Android Jetpack ComposeUse when building Android UIs with Jetpack Compose, managing state with remember/mutableStateOf, or implementing declarative UI patterns.expo/agent-templates
