What c-apps 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.
