Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It adds context about the 'live' state and 'currently registered', implying a runtime view, but does not disclose potential side effects (likely none), failure modes if the listener is not alive, or return format. The description is minimal but not misleading.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
