Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered structurally. The description adds nothing beyond that: it does not say whether the file is permanently deleted or moved to trash, whether it can be recovered, or what permissions are required — all material facts given sibling tools get_trash and restore_from_trash exist.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
