## About

# App Launcher Skill

This skill provides application control on the local system. It can launch applications, open URLs, and manage running processes.

## ⚠️ Security Note

**Launching applications requires user approval.** The agent will pause and ask for confirmation before:
- Starting any application
- Opening URLs (to prevent phishing)
- Focusing/switching to applications

## When to Use

- User asks to "open" or "launch" an application
- User wants to open a URL in their browser
- User asks what applications are running
- User wants to switch to a specific application

## Available Commands

### Launch Application
Launch an application by name.

```bash
python scripts/app_control.py launch "notepad"
python scripts/app_control.py launch "Visual Studio Code"
python scripts/app_control.py launch "chrome"
```

**Common app names:**
- Windows: notepad, calc, explorer, cmd, powershell, code, chrome, firefox
- macOS: Safari, Finder, Terminal, "Visual Studio Code", Notes
- Linux: firefox, nautilus, gnome-terminal, code

### Open URL
Open a URL in the default browser.

```bash
python scripts/app_control.py url "https://example.com"
python scripts/app_control.py url "https://github.com"
```

### List Running Applications
Show currently running applications (not all processes).

```bash
python scripts/app_control.py list
python scripts/app_control.py list --all  # Include background processes
```

### Focus Application
Bring an application window to the foreground.

```bash
python scripts/app_control.py focus "notepad"
python scripts/app_control.py focus "chrome"
```
