+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+MeTube is a web-based GUI for youtube-dl/yt-dlp that allows downloading videos from YouTube and 100+ other sites. It consists of a Python backend with aiohttp and an Angular frontend, providing real-time download progress via WebSocket.
+
+## Development Commands
+
+### Frontend Development
+```bash
+cd ui
+npm install                    # Install Angular dependencies
+npm run build                  # Build production frontend
+npm run start                  # Start development server
+npm run lint                   # Run Angular linting
+npm run test                   # Run Angular tests
+```
+
+### Backend Development
+```bash
+# Install Python dependencies using uv (preferred)
+curl -LsSf https://astral.sh/uv/install.sh | sh
+uv sync                        # Install dependencies from pyproject.toml
+uv run python3 app/main.py     # Run the backend server
+
+# Alternative using pip
+pip install -r requirements.txt
+python3 app/main.py
+```
+
+### Docker Development
+```bash
+docker build -t metube .       # Build Docker image
+docker-compose up -d           # Run with docker-compose
+docker-compose up -d --build --force-recreate  # Rebuild and restart
+```
+
+### Code Quality
+```bash
+# Python linting
+pylint app/                    # Run pylint on Python code
+
+# Type checking (if configured)
+pyright                        # Run Python type checking
+```
+
+## Architecture Overview
+
+### Backend Structure (`app/`)
+- `main.py`: Main aiohttp server with REST API and WebSocket support
+- `ytdl.py`: Download queue management, yt-dlp integration, and notifier pattern
+- `dl_formats.py`: Format selection logic for video/audio downloads
+
+### Frontend Structure (`ui/src/app/`)
+- `app.component.ts/html`: Main UI component with download interface
+- `downloads.service.ts`: HTTP client for backend API communication
+- `metube-socket.ts`: WebSocket client for real-time updates
+- `downloads.pipe.ts`: Angular pipes for formatting download info
+
+### Key Technologies
+- **Backend**: Python 3.13+, aiohttp, python-socketio, yt-dlp, shelve storage
+- **Frontend**: Angular 19+, TypeScript, Bootstrap 5, FontAwesome
+- **Communication**: REST API + WebSocket for real-time updates
+- **Storage**: Shelve-based persistent queues in STATE_DIR
+
+## Environment Configuration
+
+Key environment variables (see README.md for complete list):
+- `DOWNLOAD_DIR`: Download location (default: `/downloads`)
+- `DOWNLOAD_MODE`: `sequential`|`concurrent`|`limited` (default: `limited`)
+- `MAX_CONCURRENT_DOWNLOADS`: For limited mode (default: 3)
+- `YTDL_OPTIONS`: JSON options passed to yt-dlp
+- `URL_PREFIX`: For reverse proxy setups
+- `HOST`/`PORT`: Server binding (default: 0.0.0.0:8081)
+
+## API Endpoints
+
+### REST API
+- `POST /add`: Add new download
+- `POST /delete`: Cancel/delete download
+- `GET /history`: Get download history
+- `GET /info`: Get server info and configuration
+
+### WebSocket Events
+- `added`: New download queued
+- `updated`: Download progress update
+- `completed`: Download finished
+- `canceled`: Download canceled
+- `cleared`: Download removed from history
+
+## Next Implementation: Playlist Monitor Service
+
+The PLAYLIST_MONITOR_ARCHITECTURE.md document outlines a comprehensive plan for adding automated playlist monitoring capabilities. This should be implemented as a separate microservice.
+
+### Architecture Summary
+- **Service Type**: FastAPI-based microservice (Python 3.13+)
+- **Database**: SQLite with SQLAlchemy ORM
+- **Scheduler**: APScheduler for periodic tasks
+- **Integration**: MeTube REST API + WebSocket client
+- **Deployment**: Docker container alongside MeTube
+
+### Key Components
+1. **Playlist Manager**: Subscription management, yt-dlp integration
+2. **Video Tracker**: Status tracking, file movement handling
+3. **Scheduler Engine**: Periodic playlist checking, download triggering
+4. **State Manager**: SQLite persistence, data migrations
+5. **MeTube Client**: HTTP/WebSocket communication
+
+### Implementation Phases (6 weeks)
+- **Phase 1**: Core infrastructure, FastAPI setup, database models
+- **Phase 2**: Playlist management, yt-dlp integration, start point logic
+- **Phase 3**: Scheduler, periodic checks, MeTube integration
+- **Phase 4**: File tracking, re-downloads, error handling
+- **Phase 5**: UI integration (extend MeTube Angular or separate frontend)
+- **Phase 6**: Testing, Docker containerization, documentation
+
+### API Design
+- `/api/playlists`: CRUD operations for playlist subscriptions
+- `/api/playlists/{id}/videos`: Video status management
+- `/api/videos/{id}/download`: Manual download triggering
+- `/api/status`: System health and statistics
+
+### Database Schema
+- `playlists`: Subscription configuration
+- `videos`: Individual video tracking with status, errors, file location
+- `activity_log`: Audit trail for operations
+
+### Configuration
+```yaml
+metube:
+  url: http://localhost:8081
+scheduler:
+  default_check_interval: 60  # minutes
+  max_concurrent_downloads: 3
+database:
+  url: sqlite:///data/playlists.db
+```
+
+## Key Implementation Notes
+
+1. **Download Queue Management**: Uses async patterns with notifier callbacks for real-time updates
+2. **Format Selection**: Complex logic in `dl_formats.py` handles quality/format preferences
+3. **Error Handling**: Robust error tracking and retry mechanisms built into ytdl.py
+4. **File Organization**: Supports custom directories, templates, and file naming patterns
+5. **WebSocket Integration**: Real-time communication between backend and frontend
+6. **Docker Considerations**: Multi-stage builds, volume mounts for downloads, environment configuration
+
+## Common Development Tasks
+
+### Adding New Download Features
+1. Update `ytdl.py` for backend logic
+2. Modify `app/main.py` for new API endpoints
+3. Update frontend components in `ui/src/app/`
+4. Test with various URLs and formats
+
+### Modifying Frontend
+1. Angular components in `ui/src/app/`
+2. Use existing Bootstrap 5 styling
+3. Maintain WebSocket connection patterns
+4. Test build process with `npm run build`
+
+### Database/Storage Changes
+1. Shelve storage in STATE_DIR (default: `/downloads/.metube`)
+2. Persistent queue files: `completed`, `pending`, `queue`
+3. Cookie storage in `cookies/` subdirectory
+
+### Testing Downloads
+1. Use Docker for consistent environment
+2. Test with various sites from yt-dlp supported sites
+3. Check different quality/format combinations
+4. Verify WebSocket updates in frontend

+  --workers 4 \
+  --worker-class uvicorn.workers.UvicornWorker \
+  --bind 0.0.0.0:8082 \
+  --log-level info
+
+# Or with uvicorn directly
+uv run uvicorn app.main:app \
+  --host 0.0.0.0 \
+  --port 8082 \
+  --workers 4 \
+  --log-level info
+```
+
+## 🎨 UI Integration Options
+
+### Option 1: Standalone Web UI (Recommended)
+Create a separate frontend application that communicates with the API.
+
+**Technologies:**
+- **React** with TypeScript
+- **Vue.js 3** with Composition API
+- **SvelteKit** for modern approach
+
+**Example React setup:**
+```bash
+# Create React app
+cd /root/workspace/tubewatch
+npx create-react-app playlist-monitor-ui --template typescript
+cd playlist-monitor-ui
+
+# Install UI libraries
+npm install @mui/material @emotion/react @emotion/styled axios react-query
+npm install @mui/icons-material @mui/x-data-grid date-fns
+
+# Start development
+npm start
+```
+
+### Option 2: Extend MeTube Angular UI
+Modify the existing MeTube Angular frontend to include playlist monitoring.
+
+**Approach:**
+1. Add new Angular components to MeTube's UI
+2. Integrate with existing MeTube routing
+3. Use MeTube's existing styling and components
+
+**Integration points:**
+- Add playlist tab to main navigation
+- Extend existing download interface
+- Reuse MeTube's component library
+
+### Option 3: Simple HTML Dashboard
+For minimal UI requirements.
+
+```bash
+# Create simple dashboard
+mkdir ui
+cd ui
+
+# Create index.html with vanilla JS
+cat > index.html << 'EOF'
+<!DOCTYPE html>
+<html>
+<head>

+        const data = await response.json();
+        displayPlaylists(data);
+    } catch (error) {
+        console.error('Error loading playlists:', error);
+    }
+}
+
+function displayPlaylists(playlists) {
+    const container = document.getElementById('playlists');
+    container.innerHTML = playlists.map(playlist => `
+        <div class="card mb-3">
+            <div class="card-body">
+                <h5 class="card-title">${playlist.title || 'Untitled'}</h5>
+                <p class="card-text">${playlist.url}</p>
+                <p>Status: ${playlist.enabled ? 'Enabled' : 'Disabled'}</p>
+            </div>
+        </div>
+    `).join('');
+}
+
+loadPlaylists();
+EOF
+```

+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://www.youtube.com/playlist?list=PLrAXtmErZgOeiKm4sgNOknGvNjby9efdf",
+    "check_interval": 60,
+    "quality": "best",
+    "format": "mp4",
+    "folder": "kurzgesagt"
+  }'
+```
+
+### Path 2: Add Simple UI (30 minutes)
+```bash
+# Create basic HTML dashboard
+cd /root/workspace/tubewatch/playlist-monitor
+mkdir ui
+cp templates/simple-dashboard.html ui/index.html
+
+# Modify backend to serve UI
+echo "app.mount('/ui', StaticFiles(directory='ui', html=True), name='ui')" >> app/main.py
+
+# Restart and access UI
+uv run python -m app.main
+open http://localhost:8082/ui
+```
+
+### Path 3: Full React App (2-4 hours)
+```bash
+# Create React application
+cd /root/workspace/tubewatch
+npx create-react-app playlist-monitor-ui --template typescript
+cd playlist-monitor-ui
+
+# Install UI libraries
+npm install @mui/material @emotion/react @emotion/styled axios react-query

+# Playlist Monitor Service
+
+An automated playlist monitoring service for MeTube that tracks YouTube playlists, detects new videos, and automatically downloads them using MeTube as the download engine.
+
+## Features
+
+- **Playlist Monitoring**: Automatically monitor YouTube playlists for new videos
+- **Smart Download Management**: Track download status and prevent re-downloads
+- **Start Point Control**: Set starting points to skip older videos
+- **File Movement Tracking**: Handle files moved by users without re-downloading
+- **Periodic Checking**: Configurable check intervals for each playlist
+- **MeTube Integration**: Seamless integration with MeTube via REST API and WebSocket
+- **Real-time Updates**: WebSocket events for download progress and completion
+- **Comprehensive API**: RESTful API for managing playlists and videos
+- **Docker Support**: Easy deployment with Docker Compose
+
+## Quick Start
+
+### Prerequisites
+
+- Python 3.13+
+- MeTube instance running (default: http://localhost:8081)
+- SQLite or PostgreSQL database
+
+### Installation
+
+1. **Clone and setup**:
+   ```bash
+   cd playlist-monitor
+   cp .env.example .env
+   # Edit .env with your configuration
+   ```
+
+2. **Install dependencies** (using uv recommended):
+   ```bash
+   curl -LsSf https://astral.sh/uv/install.sh | sh
+   uv sync
+   ```
+
+3. **Run the service**:
+   ```bash
+   uv run python -m app.main
+   ```
+
+### Docker Deployment
+
+```bash
+docker build -t playlist-monitor .
+docker run -d \
+  --name playlist-monitor \
+  -p 8082:8082 \
+  -e METUBE_URL=http://metube:8081 \
+  -v ./data:/app/data \
+  -v ./logs:/app/logs \
+  playlist-monitor
+```
+
+## API Documentation
+
+Once running, visit http://localhost:8082/docs for interactive API documentation.
+
+### Key Endpoints
+
+- `POST /api/playlists` - Add a new playlist
+- `GET /api/playlists` - List all playlists
+- `GET /api/playlists/{id}` - Get playlist details
+- `POST /api/playlists/{id}/check` - Manually check playlist for new videos
+- `POST /api/videos/{id}/download` - Trigger download for a video
+- `GET /api/status` - Get system status
+
+## Configuration
+
+See `.env.example` for all configuration options. Key settings:
+
+- `METUBE_URL`: URL of your MeTube instance

+
+## 🎯 Test Execution Strategies
+
+### Parallel Testing
+```bash
+# Run tests in parallel
+uv run pytest -n auto
+
+# Run specific test categories in parallel
+uv run pytest tests/unit/ -n 4 &
+uv run pytest tests/integration/ -n 2 &
+wait
+```
+
+### Test Selection
+```bash
+# Run tests by marker
+uv run pytest -m "not performance"
+uv run pytest -m "performance"
+
+# Run tests by name pattern
+uv run pytest -k "test_playlist"
+uv run pytest -k "not test_performance"
+
+# Run specific test file
+uv run pytest tests/unit/test_models.py
+```
+
+### Continuous Testing
+```bash
+# Watch mode for development
+uv run pytest-watch tests/unit/
+
+# Run on file changes
+uv run ptw -- tests/unit/
+```
+
+## 📚 Testing Best Practices
+
+### 1. Test Naming
+```python
+def test_playlist_creation_with_valid_url(self):
+    """Should create playlist when valid YouTube URL provided"""
+    # Test implementation
+
+def test_playlist_creation_fails_with_invalid_url(self):
+    """Should reject playlist creation with invalid URL"""
+    # Test implementation
+```
+
+### 2. Test Independence
+```python
+@pytest.fixture
+def clean_database():
+    """Provide clean database for each test"""
+    # Setup clean state
+    yield
+    # Cleanup after test
+```
+
+### 3. Mock External Services
+```python
+@pytest.fixture
+def mock_metube():
+    """Mock MeTube service for testing"""
+    with respx.mock:
+        respx.get("http://localhost:8081/info").mock(
+            return_value=Response(200, json={"status": "ok"})
+        )
+        yield
+```
+
+### 4. Test Data Management
+```python
+@pytest.fixture
+def sample_playlist():
+    """Provide sample playlist data"""
+    return {
+        "url": "https://www.youtube.com/playlist?list=TEST123",
+        "title": "Test Playlist",
+        "check_interval": 60
+    }
+```

+# Playlist Monitor Service
+
+An automated playlist monitoring service for MeTube that tracks YouTube playlists, detects new videos, and automatically downloads them using MeTube as the download engine.
+
+## Features
+
+- **Playlist Monitoring**: Automatically monitor YouTube playlists for new videos
+- **Smart Download Management**: Track download status and prevent re-downloads
+- **Start Point Control**: Set starting points to skip older videos
+- **File Movement Tracking**: Handle files moved by users without re-downloading
+- **Periodic Checking**: Configurable check intervals for each playlist
+- **MeTube Integration**: Seamless integration with MeTube via REST API and WebSocket
+- **Real-time Updates**: WebSocket events for download progress and completion
+- **Comprehensive API**: RESTful API for managing playlists and videos
+- **Docker Support**: Easy deployment with Docker Compose
+
+## Quick Start
+
+### Prerequisites
+
+- Python 3.13+
+- MeTube instance running (default: http://localhost:8081)
+- SQLite or PostgreSQL database
+
+### Installation
+
+1. **Clone and setup**:
+   ```bash
+   cd playlist-monitor
+   cp .env.example .env
+   # Edit .env with your configuration
+   ```
+
+2. **Install dependencies** (using uv recommended):
+   ```bash
+   curl -LsSf https://astral.sh/uv/install.sh | sh
+   uv sync
+   ```
+
+3. **Run the service**:
+   ```bash
+   uv run python -m app.main
+   ```
+
+### Docker Deployment
+
+```bash
+docker build -t playlist-monitor .
+docker run -d \
+  --name playlist-monitor \
+  -p 8082:8082 \
+  -e METUBE_URL=http://metube:8081 \
+  -v ./data:/app/data \
+  -v ./logs:/app/logs \
+  playlist-monitor
+```
+
+## API Documentation
+
+Once running, visit http://localhost:8082/docs for interactive API documentation.
+
+### Key Endpoints
+
+- `POST /api/playlists` - Add a new playlist
+- `GET /api/playlists` - List all playlists
+- `GET /api/playlists/{id}` - Get playlist details
+- `POST /api/playlists/{id}/check` - Manually check playlist for new videos
+- `POST /api/videos/{id}/download` - Trigger download for a video
+- `GET /api/status` - Get system status
+
+## Configuration
+
+See `.env.example` for all configuration options. Key settings:
+
+- `METUBE_URL`: URL of your MeTube instance
+- `DATABASE_URL`: Database connection string
+- `DEFAULT_CHECK_INTERVAL`: Default playlist check interval (minutes)
+- `MAX_CONCURRENT_DOWNLOADS`: Maximum concurrent downloads
+- `LOG_LEVEL`: Logging level (DEBUG, INFO, WARNING, ERROR)
+
+## Architecture
+
+The service consists of:
+
+- **FastAPI**: Modern async web framework
+- **SQLAlchemy**: Database ORM with SQLite/PostgreSQL support
+- **APScheduler**: Periodic task scheduling
+- **yt-dlp**: YouTube playlist and video information extraction
+- **MeTube Client**: HTTP/WebSocket client for MeTube integration
