AI teammates know the room they're in — its messages, its artifacts, the decisions that happened there. They don't automatically know other rooms, even in the same workspace. They never know other workspaces.
If you want a teammate that spans rooms — for example, a research assistant working across multiple project rooms — you grant that broader access explicitly. Broader access is visible, not implicit. You'll see what each teammate can see, on the teammate's settings.
There's no hidden “AI memory” silently collecting context outside the rooms it's in. If we're remembering something, you can find where it came from.
