Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations signal that this is a non-read-only, non-idempotent, open-world operation, so the description should explain the side effects of a refresh, but it does not. It adds only the scope 'for the authenticated user' and the fact that host polling is the target; there is no mention of background work, cache invalidation, or external effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
