list_spaces
List the user's memory workspaces: their personal tree, the team spaces they belong to, which one is the default for new sessions, and (if known) which one THIS session is pinned to.
The list_spaces tool is provided by Assertion Memory. Install that server in your AI client and the assistant can call it directly.
