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 the deletion is permanent/irreversible, what happens to subtasks by default, or whether the issue must be unlinked first. With annotations lowering the bar, a bare restatement still leaves meaningful behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
