Shortcuts on the Apple Watch provides a quick-access way to run your shortcuts from your wrist, either by opening the Shortcuts app or setting a shortcut as a complication on a Watch face and tapping that to run it.
Shortcuts run from an Apple Watch face complication must be confirmed before running in order to avoid accidental triggers when your wrist brushes up against something.
Shortcuts from the Apple Watch do not work with every action, so functionality like copy to the clipboard or setting device playback is not possible from the Apple Watch – any actions that won’t work with Apple Watch will be specified as such in the shortcuts’ options.
Some advanced functionality, like Run Script over SSH or Get Contents of URL (for API calls) do still work from the watch, however, so there is some unique potential there.
Shortcuts for Apple Watch are organized into their own automatic group – changing the order there will reflect the changes in the order of shortcuts on your watch.
