Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. The verb 'Get' and 'Scope: storage:read' disclose that this is a read-only operation, which is useful. However, it does not describe what statistics are returned, whether the data is aggregated, or any response format, so it is only minimally transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
