Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The readOnlyHint annotation already establishes this is a safe read, and the description adds nothing beyond that – no detail on what a queue version contains, error behavior for a missing id, or return shape. For a read-only lookup this is tolerable but the description contributes no behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
