Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already convey read-only, idempotent, and non-destructive behavior. The description adds the 'pending and not yet accepted' filter, but does not disclose pagination behavior, ordering, or any account-authorization expectations beyond what the schema suggests.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
