Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden of behavioral disclosure. 'Remove' signals a destructive operation, but the description does not state whether the removal is permanent, whether it has side effects on alerts or watches, whether it is idempotent, or how errors such as a missing monitor ID are handled.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
