Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare the tool read-only, idempotent, and non-destructive, and the description does not contradict them. It adds useful context by saying the result is bounded metadata scoped to the authenticated user, but it does not disclose pagination behavior, ordering, or other limitations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
