Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full burden. It indicates a read-only listing operation with no destructive behavior, which is appropriate. However, it lacks details on pagination or authentication. For a simple list with no parameters, this is minimally adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
