Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears full burden for behavioral disclosure. It lists possible status values (READY_FOR_DATA, READY_FOR_WRITE, PROCESSING, COMPLETED, FAILED), which is helpful. However, it does not state whether the operation is read-only, idempotent, or has side effects, leaving gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
