Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description must disclose behavioral traits. The word 'status' weakly implies a read-only query, but it does not describe what the tool returns, whether it requires an active session, or how it behaves with an invalid/empty session_id. This lack of detail leaves the agent guessing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
