Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. It does not state that this is a read-only, zero-argument query, what host application the workspaces belong to (Premiere Pro), or what the caller should do with the returned names; for a harmless read tool that is a modest gap, but the disclosure is still nearly absent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
