# Device Control Skill

Control device volume, brightness, and applications via command line. Supports Linux, macOS, Windows, and WSL.

## Security

All inputs are validated and sanitized to prevent command injection:
- Volume/brightness values must be numbers between 0-100
- App names are restricted to alphanumeric characters, spaces, dashes, and underscores
- Shell metacharacters are blocked

## Tool API

### device_control
Execute a device control action.

- **Parameters:**
  - `action` (string, required): One of `set_volume`, `change_volume`, `set_brightness`, `open_app`, `close_app`.
  - `value` (string/number, optional): The value for the action (0-100 for volume/brightness, delta for change_volume).
  - `app` (string, optional): The application name or path (required for open/close actions).

**Usage:**

```bash
# Set volume to 50%
node skills/device-control/ctl.js --action set_volume --value 50

# Change volume by +10 or -10
node skills/device-control/ctl.js --action change_volume --value 10
node skills/device-control/ctl.js --action change_volume --value -10

# Set brightness to 75%
node skills/device-control/ctl.js --action set_brightness --value 75

# Open an application
node skills/device-control/ctl.js --action open_app --app "firefox"
node skills/device-control/ctl.js --action open_app --app "Visual Studio Code"

# Close an application
node skills/device-control/ctl.js --action close_app --app "firefox"
```
