Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so safety is fully covered. The description adds some return-content context (status, remaining actions, file number) but, with no output schema present, it leaves the shape and meaning of those fields underspecified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
