Desktop actions

On supported macOS builds, Settings → Agent → Actions controls native desktop actions. These include editing selected text, drafting replies, creating prompts, reminders, music and volume, opening apps, and screen context.

Enable only what you need

Review the switches before your first action. Draft replies starts off in the current candidate; other actions have their own defaults. Turning off an action removes that capability from the intended agent tool path. It does not revoke an unrelated app’s operating-system permissions.

Know what the result means

Request	Expected result
Draft a reply	An editable draft/card and clipboard text, not an automatically sent message.
Create a prompt	A staged prompt you can inspect and paste yourself.
Edit selected text	Replacement in the selected editable field; review it in the destination app.
Open an app or site	An attempt to open the named installed app or address.
Control music	Playback or volume action against a supported running player or system control.
Explain the screen	Screen context for the model when permission and feature access allow it.

For edits, use the destination app’s Undo if the replacement is wrong. For a drafted message, review the recipient and text before you send it yourself.

When an action fails

Read the card’s error. Confirm the app is installed, the intended field has focus, and the necessary permissions are granted. If screen context is unavailable, give a description rather than assuming Nock saw it. Repeating a request without checking the previous outcome can cause duplicate actions.

Native execution happens on the computer, but your request, relevant selected text, or a requested screenshot can be sent to the model. See Privacy.
