Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish this is a non-read-only, non-destructive, non-open-world mutation, which fits holding a job. The description adds the state constraint (pending) and ownership constraint, but does not state that the action is reversible via release or note any permission requirements beyond ownership.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
