## What it does

The skill explains how to find apps with `mas search`, install them by ID, and check for updates. You can also use `mas list` to see installed apps, while `mas info` shows app details and `mas open` opens an app’s App Store page.

You must be signed in to the Mac App Store. On macOS 15 and later, installing or updating requires an administrator password. Paid apps work after purchase. Since `mas upgrade` updates every app with an available update, confirm with the user before running it.

## When to use it
- find an app’s Mac App Store ID
- install an app by its ID
- list installed apps
- check which apps have updates
- update a selected app with `mas`

## Example prompts

# Mac App Store (mas)

```bash
# Search for apps
mas search Xcode
mas search "Bear Notes"

# Install by app ID
mas install 497799835    # Xcode

# List installed apps
mas list

# Check for outdated apps
mas outdated

# Upgrade all outdated apps
mas upgrade

# Upgrade specific app
mas upgrade 497799835

# Show app info
mas info 497799835

# Open app page in App Store
mas open 497799835
```

## Guidelines

- User must be signed into the Mac App Store
- On macOS 15+, install/upgrade requires admin password
- Use `mas search` to find app IDs before installing
- `mas upgrade` updates all apps — confirm with user first
- Free and paid apps both work (paid requires prior purchase)
