([#3805](https://github.com/expo/eas-cli/pull/3805) by [@sswrk](https://github.com/sswrk))
+- [eas-cli] Add support for non-interactive `eas update:rollback [GROUP_ID]`. The given update group must be the latest for its branch and runtime version; the previous update group is republished, or a roll back to the embedded update is published if there is none. ([#3825](https://github.com/expo/eas-cli/pull/3825) by [@quinlanj](https://github.com/quinlanj))

-## Project Overview
-
 This is an Expo/React Native mobile application. Prioritize mobile-first patterns, performance, and cross-platform compatibility.

-## Documentation Resources
+## Expo has changed — do not trust your training data

-When working on this project, **always consult the official Expo documentation** available at:
+Expo ships breaking changes every SDK release. APIs you remember are likely renamed, moved, or removed. Before writing any code that touches an Expo, EAS, or React Native API:

- **https://docs.expo.dev/llms.txt** - Index of all available documentation files
- **https://docs.expo.dev/llms-full.txt** - Complete Expo documentation including Expo Router, Expo Modules API, development process
- **https://docs.expo.dev/llms-eas.txt** - Complete EAS (Expo Application Services) documentation
- **https://docs.expo.dev/llms-sdk.txt** - Complete Expo SDK documentation
- **https://reactnative.dev/docs/getting-started** - Complete React Native documentation
+1. Read the major version of the `expo` package in `package.json`.
+2. Fetch the matching versioned docs: `https://docs.expo.dev/versions/v<major>.0.0/`
+3. For anything else, fetch https://docs.expo.dev/llms.txt — an index of all Expo docs with corrections to common LLM misconceptions. Follow its links to the specific page you need; never answer from memory.

-These documentation files are specifically formatted for AI agents and should be your **primary reference** for:
+## Commands

- Expo APIs and best practices
- Expo Router navigation patterns
- EAS Build, Submit, and Update workflows
- Expo SDK modules and their usage
- Development and deployment processes

-## Essential Commands
-
-### Development
+Use `bunx` instead of `npx` if the project uses bun (`bun.lock` present).

 ```bash
-npx expo start                  # Start dev server
-npx expo start --clear          # Clear cache and start dev server
-npx expo install <package>      # Install packages with compatible versions
-npx expo install --check        # Check which installed packages need to be updated
-npx expo install --fix          # Automatically update any invalid package versions
-npm run development-builds      # Create development builds (workflow)
-npm run reset-project           # Reset to blank template
+npx expo install <package>  # ALWAYS use instead of npm/yarn/pnpm/bun add — resolves SDK-compatible versions
+npx expo start              # start the dev server
+npx expo lint               # lint
+npx tsc --noEmit            # typecheck
+npx expo-doctor             # diagnose dependency and config issues
+npx expo install --fix      # fix incompatible package versions
 ```

-### Building & Testing
+Run lint and typecheck before declaring any task done.

-```bash
-npx expo doctor      # Check project health and dependencies
-npx expo lint        # Run ESLint
-npm run draft        # Publish preview update and website (workflow)
-```
+## Navigation & Routing

-### Production
+- Use **Expo Router** for all navigation. Routes live in `src/app/` — every file there is a screen, `_layout.tsx` files define navigators. Keep non-route code (components, hooks, utils) outside `src/app/`.
+- Import `Link`, `router`, and `useLocalSearchParams` from `expo-router`.
+- Docs: https://docs.expo.dev/router/introduction.md

-```bash

+## Building with EAS

-## Development Guidelines
+Use EAS to build, sign, and submit the app in the cloud (`eas build`, `eas submit`) and to ship over-the-air updates (`eas update`) — no local Xcode or Android Studio required. Run EAS CLI as `bunx eas-cli <command>` in Bun projects, or `npx eas-cli@latest <command>` otherwise; substitute that for bare `eas` in docs examples.
+Docs: https://docs.expo.dev/eas/index.md

-### Code Style & Standards
+## Rules

- **TypeScript First**: Use TypeScript for all new code with strict type checking
- **Naming Conventions**: Use meaningful, descriptive names for variables, functions, and components
- **Self-Documenting Code**: Write clear, readable code that explains itself; only add comments for complex business logic or design decisions
- **React 19 Patterns**: Follow modern React patterns including:
-  - Function components with hooks
-  - Enable React Compiler
-  - Proper dependency arrays in useEffect
-  - Memoization when appropriate (useMemo, useCallback)
-  - Error boundaries for better error handling
-
-### Navigation & Routing
-
- Use **Expo Router** for all navigation
- Import `Link`, `router`, and `useLocalSearchParams` from `expo-router`
- Docs: https://docs.expo.dev/router/introduction/
-
-### Recommended Libraries
-
- **Navigation**: `expo-router` for navigation
- **Images**: `expo-image` for optimized image handling and caching
- **Animations**: `react-native-reanimated` for performant animations on native thread
- **Gestures**: `react-native-gesture-handler` for native gesture recognition
- **Storage**: Use `expo-sqlite` for persistent storage, `expo-sqlite/kv-store` for simple key-value storage
-
-## Debugging & Development Tools
-
-### DevTools Integration
-
- **React Native DevTools**: Use MCP `open_devtools` command to launch debugging tools
- **Network Inspection**: Monitor API calls and network requests in DevTools
- **Element Inspector**: Debug component hierarchy and styles
- **Performance Profiler**: Identify performance bottlenecks
- **Logging**: Use `console.log` for debugging (remove before production), `console.warn` for deprecation notices, `console.error` for actual errors, and implement error boundaries for production error handling
-
-### Testing & Quality Assurance
-
-#### Automated Testing with MCP Tools
-
-Developers can configure the Expo MCP server with the following doc: https://docs.expo.dev/eas/ai/mcp/
-
- **Component Testing**: Add `testID` props to components for automation
- **Visual Testing**: Use MCP `automation_take_screenshot` to verify UI appearance
- **Interaction Testing**: Use MCP `automation_tap_by_testid` to simulate user interactions
- **View Verification**: Use MCP `automation_find_view_by_testid` to validate component rendering
-
-## EAS Workflows CI/CD
-
-This project is pre-configured with **EAS Workflows** for automating development and release processes. Workflows are defined in `.eas/workflows/` directory.
-
-When working with EAS Workflows, **always refer to**:
-
- https://docs.expo.dev/eas/workflows/ for workflow examples
- The `.eas/workflows/` directory for existing workflow configurations
- You can check that a workflow YAML is valid using the workflows schema: https://exp.host/--/api/v2/workflows/schema
-
-### Build Profiles (eas.json)
-
- **development**: Development builds with dev client
- **development-simulator**: Development builds for iOS simulator
- **preview**: Internal distribution preview builds
- **production**: Production builds with auto-increment
-
-## Troubleshooting
-
-### Expo Go Errors & Development Builds
-
-If there are errors in **Expo Go** or the project is not running, create a **development build**. **Expo Go** is a sandbox environment with a limited set of native modules. To create development builds, run `eas build:dev`. Additionally, after installing new packages or adding config plugins, new development builds are often required.
-
-## AI Agent Instructions
-
-When working on this project:
-
-1. **Always start by consulting the appropriate documentation**:
-   - For general Expo questions: https://docs.expo.dev/llms-full.txt
-   - For EAS/deployment questions: https://docs.expo.dev/llms-eas.txt
-   - For SDK/API questions: https://docs.expo.dev/llms-sdk.txt
-
-2. **Understand before implementing**: Read the relevant docs section before writing code
-
-3. **Follow existing patterns**: Look at existing components and screens for patterns to follow
+- If `ios/` and `android/` directories do not exist, they are generated (Continuous Native Generation). Never create or edit them by hand — configure native behavior in `app.json` and config plugins.
+- Expo Go only includes its bundled native modules. After adding a library with native code, the app needs a development build: `npx expo run:ios|android` locally, or `eas build --profile development`.
+- Prefer recommended Expo modules over third-party libraries, and check your available skills before adding dependencies. Docs: https://docs.expo.dev/versions/latest/index.md
