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 doesn't say whether the status is a snapshot or blocking, whether it requires prior delivery, what states are possible, or the return format. Only the minimal 'status query' behavior is implied.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
