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. The description adds the specific status values returned and the presence of a result URL upon completion, which provides useful behavioral context beyond the annotations. It does not detail error handling or polling behavior, but the core safety and result traits are covered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
