Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover read-only, idempotent, and non-destructive behavior. The description adds genuinely useful behavioral context beyond those annotations: archived claims are omitted, claims are returned with roles and current statuses, and a tier restriction (paid + free, sample rejected) is disclosed. No contradiction exists.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
