Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It communicates that only active tenants are returned, which is a useful scoping detail. However, it does not mention potential pagination, ordering, authentication, or whether the full list is always returned at once.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
