Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. It discloses that the operation is a read-only listing scoped to an account, but it does not mention pagination, response shape, permissions, or rate-limit considerations. The core behavior is minimally transparent but not detailed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
