What works well
Reading a fleet. “List every screen in the Frankfurt plant and show which are offline.” One call and some filtering.
Bulk changes through labels. “Find every screen labeled Warehouse and assign the Safety Rotation playlist to them.” Labels are the assistant’s lever on a fleet, exactly as they are yours.
Assembling a playlist. “Add this video to the start of the Logistics Briefing playlist” is a create then a position update.
Publishing something it just made. See Publish HTML as an app.
What does not
Anything a tool does not cover. There is no tool to pair a screen, change a screen’s settings, or edit an app’s configuration, so an assistant cannot do those however it is asked. See Tool reference.
Anything across workspaces. One token, one workspace.
Judgement about what should be on a wall. An assistant will happily put a draft on fifty screens if that is what it was asked for.
Keeping it safe
Scope the token to the access the assistant needs. See Permissions.
Turn on confirmations if your client supports them. Every destructive tool is annotated, so a client can prompt before deleting a playlist.
Work on a label, not on everything. Ask for changes scoped to a label you control rather than to all screens. The blast radius of a misunderstood instruction is then one group rather than the fleet.
Check Now playing afterwards. A screen’s own page shows what is actually active on it, which is the fastest way to confirm an assistant did what you meant. See A screen’s own page.
