## Example Prompts

### Basic Usage
- "Take a screenshot of my phone"
- "What's the current screen resolution and density?"
- "List all installed apps containing 'flutter'"
- "What's currently on screen? Get all the text"

### UI Testing
- "Find the login button and tap it"
- "Scroll down until you find 'Settings'"
- "Get all clickable elements and their positions"
- "Type 'test@email.com' into the current field"

### Debugging
- "Show me the last 50 Flutter logs"
- "Are there any crash logs for my app?"
- "What's the memory usage of com.myapp?"

### Visual QA
- "Capture this screen for comparison with Figma"
- "Take a screenshot and tell me about the UI structure"
- "Set the font scale to 1.3 and take a screenshot for accessibility testing"

### Performance Testing
- "Set animation scale to 0 and run through the app"
- "Get frame stats for my app - is there any jank?"
- "What's the GPU rendering performance?"

### Device Simulation
- "Change the screen to 1080x1920 to simulate a smaller phone"
- "Rotate to landscape mode"

## Extending

Add new tools easily:

```python
@mcp.tool()
def my_custom_tool(param: str, device_serial: str | None = None) -> str:
    """Description shown to AI"""
    return run_adb(["shell", "your-command", param], device_serial)
```

## Tips for Flutter Development

1. **Speed up tests**: Use `set_animation_scale(0)` to disable animations
2. **Visual QA**: Use `capture_screen_for_comparison()` with Figma MCP
3. **Debug logs**: `get_flutter_logs()` filters Flutter-specific output
4. **Hot reload**: Keep `flutter run` terminal open, use device for interaction
5. **Responsive testing**: Use `change_screen_size()` and `change_density()`
