Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are available, so the description carries the full burden of behavioral disclosure. It only mentions 'active' alerts but does not disclose that includeAcknowledged defaults to false, what constitutes an 'active' alert, or any details about the response format or filtering behavior. This is minimal for a getter.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
