Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover readOnly, idempotent, non-destructive. The description adds that it lists published entries and what they cover, but doesn't clarify any unusual behavior like default pagination or error handling. Given annotations, it is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
