+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+ScorePad with Rounds is a React Native app built with Expo SDK 52 for tracking game scores with round-by-round history. The app is cross-platform (iOS, Android, Web) and uses TypeScript throughout.
+
+## Development Commands
+
+### Setup
+```bash
+nvm use  # Use correct Node version
+npx react-native-clean-project  # Clean project if needed
+npx expo prebuild  # Generate native code
+```
+
+### Development
+```bash
+npm run dev  # Start development server with APP_VARIANT=development
+npm start  # Standard expo start with dev client
+npm run android  # Run on Android
+npm run ios  # Run on iOS
+```
+
+### Testing and Linting
+```bash
+npm run test  # Run all tests with Jest
+npm run test:watch  # Run tests in watch mode
+npm run lint  # Run ESLint and TypeScript checks
+```
+
+### Building
+```bash
+# Development builds
+npx eas build --profile development-simulator --platform ios --local
+npx eas build --profile development-simulator --platform android --local
+
+# Preview builds
+npx eas build --platform ios --profile preview --local
+npx eas build --platform android --profile preview --local
+
+# Production builds (remember to bump version in app.config.js)
+npx expo-doctor
+npx expo prebuild
+npx eas build --platform ios
+npx eas build --platform android
+```
+
+## Architecture
+
+### State Management
+- **Redux Toolkit** with RTK Query for state management
+- **Redux Persist** for data persistence with platform-specific storage:
+  - iOS: iCloud storage via custom `iCloudStorage` utility
+  - Android/Web: AsyncStorage
+- Three main slices:
+  - `GamesSlice`: Game entities with rounds, players, and metadata
+  - `PlayersSlice`: Player entities with scores per round
+  - `SettingsSlice`: App settings and preferences
+
+### Navigation
+- **React Navigation v6** with native stack navigator
+- Main screens: List (Home), Game, Settings, Share, EditPlayer, Onboarding, AppInfo
+- Custom headers for each screen using dedicated header components
+
+### Key Components Structure
+- `src/components/`: Reusable UI components organized by feature
+  - `PlayerTiles/AdditionTile/`: Complex score display with animations
+  - `Sheets/`: Bottom sheet modals with context providers
+  - `Headers/`: Custom navigation headers
+  - `Interactions/`: Touch interaction handling (HalfTap, Swipe)
+- `src/screens/`: Main screen components
+- `redux/`: State management with typed hooks and selectors
+
+### Platform-Specific Features
+- App variants for development/preview/production with different bundle IDs
+- Firebase Analytics and Crashlytics integration
+- iCloud document storage on iOS
+- Gesture handling with react-native-gesture-handler and react-native-reanimated
+
+### Testing
+- Jest with React Native Testing Library
+- Custom mocks for Firebase, AsyncStorage, and react-native-video
+- Test files co-located with source files using `.test.ts(x)` suffix
+
+## Code Style
+- ESLint with TypeScript rules, import ordering, and Prettier integration
+- Single quotes, semicolons required
+- Alphabetical import ordering with React imports first
+- No disabled tests, imports organized by type (builtin, external, internal, etc.)
+
+## Firebase Integration
+- Analytics can be disabled via `EXPO_PUBLIC_FIREBASE_ANALYTICS=false`
+- Debug mode available with simulator flags:
+  - Analytics: `-FIRAnalyticsDebugEnabled`
+  - Crashlytics: `-FIRDebugEnabled`
+
+## Development Notes
+- Use `npx expo start --dev-client` for development with React DevTools
+- Android development requires JDK 17
+- Version bumping required in `app.config.js` for production builds
+- EAS CLI used for building and submitting to stores

Subject: [PATCH 3/9] Enhance CI workflows and testing documentation

- Update node.yml to improve test coverage reporting and add TypeScript checks.
- Introduce pr-checks.yml for faster feedback on pull requests with linting and testing.
- Expand Contributing.md with detailed testing instructions and coverage requirements.
- Adjust jest.config.ts coverage thresholds to align with new requirements.

 ### EAS
 
 Debug eas config settings: `npx eas config --platform=ios --profile=development`
+
+## Testing
+
+### Run Tests
+
+```zsh
+# Run tests once
+npm test
+
+# Run tests with coverage
+npm run test:coverage
+
+# Run tests in watch mode
+npm run test -- --watch
+```
+
+### Coverage Requirements
+
+- **Statements**: 24% minimum
+- **Branches**: 18% minimum  
+- **Functions**: 20% minimum
+- **Lines**: 25% minimum
+
+Coverage reports are generated in the `coverage/` directory and include:
+- Text summary (console output)
+- HTML report (`coverage/lcov-report/index.html`)
+- LCOV format for CI integration
+
+### Writing Tests
+
+- Use React Native Testing Library for component tests
+- Mock external dependencies (react-native-reanimated, navigation, etc.)
+- Follow existing test patterns in the codebase
+- Ensure tests are deterministic and don't rely on timers
+
+## Code Quality
+
+### Linting
+
+```zsh
+# Run ESLint and TypeScript checks
+npm run lint
+
+# Auto-fix linting issues where possible
+npx eslint . --fix
+```
+
+### CI/CD
+
+The project uses GitHub Actions for continuous integration:
+
+#### Main Workflow (`node.yml`)
+- Runs on push to `main` and all pull requests to `main`
+- Executes linting, TypeScript checks, and full test suite with coverage
+- Uploads coverage reports as GitHub artifacts
+- Posts coverage summaries on pull requests
+
+#### PR Checks (`pr-checks.yml`)
+- Runs on all feature branches and pull requests
+- Provides faster feedback with basic linting and testing
+- Shows coverage summary in GitHub Actions summary
+
+#### Quality Gates
+- All tests must pass
+- Code must pass ESLint rules
+- TypeScript compilation must succeed
+- Coverage thresholds must be met
+- No merge to main without passing CI
+
+### Pre-commit Checklist
+
+Before creating a pull request:
+
+1. Run `npm run lint` and fix any issues
+2. Run `npm run test:coverage` and ensure all tests pass
+3. Verify coverage hasn't decreased significantly
+4. Test the app functionality manually
+5. Update tests for any new features or bug fixes

 ### Platform-Specific Features
+
 - App variants for development/preview/production with different bundle IDs
 - Firebase Analytics and Crashlytics integration
 - iCloud document storage on iOS
 - Gesture handling with react-native-gesture-handler and react-native-reanimated
 
 ### Testing
+
 - Jest with React Native Testing Library
 - Custom mocks for Firebase, AsyncStorage, and react-native-video
 - Test files co-located with source files using `.test.ts(x)` suffix
 
 ## Code Style
+
 - ESLint with TypeScript rules, import ordering, and Prettier integration
 - Single quotes, semicolons required
 - Alphabetical import ordering with React imports first
 - No disabled tests, imports organized by type (builtin, external, internal, etc.)
 
 ## Firebase Integration
+
 - Analytics can be disabled via `EXPO_PUBLIC_FIREBASE_ANALYTICS=false`
 - Debug mode available with simulator flags:
   - Analytics: `-FIRAnalyticsDebugEnabled`
   - Crashlytics: `-FIRDebugEnabled`
 
 ## Development Notes
+
 - Use `npx expo start --dev-client` for development with React DevTools
 - Android development requires JDK 17
 - Version bumping required in `app.config.js` for production builds
