Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false and destructiveHint=true, so the description's 'Deletes' is consistent. However, the description adds no extra behavioral context beyond what annotations provide—no mention of irreversibility, side effects on product, or whether it is a hard delete. With annotations covering the safety profile, the description adds minimal value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
