About Siri and shortcuts
You can use Siri with shortcuts in two ways:
Add to Siri: You can add shortcuts to Siri and then ask Siri to run them. See Use Siri to run shortcuts with your voice.
Siri Suggestions: Siri identifies shortcuts that may be useful to you based on how you use your iOS device—your app usage; your browser, email, and messaging history; and so on. These suggested shortcuts appear on your iOS Lock screen, in search results on your iOS Home screen, and in Settings. See Use suggested shortcuts.
