Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare this is a non-read-only, non-destructive, closed-world operation, so the safety profile is covered. The description adds the scope qualifier 'displayed sweep', but says nothing about whether the pause is reversible (only implied by the sibling resume_sweep) or what state the sweep is left in.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
