Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, idempotentHint=true and destructiveHint=false, so the safety profile is largely covered structurally. The description adds the all-vs-acknowledged scope, but it never says whether a cleared alert is gone permanently or merely hidden from the list, nor whether the clearance is server-side or view-only — the one behavioral question an agent actually has here. The "Remove" wording also sits in tension with destructiveHint=false and is never reconciled.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
