Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered externally. The description adds no behavioral context beyond the word 'Delete' – it does not explain whether deletion is permanent, what data is removed, or whether related history is affected. It does not contradict the annotations, but it contributes nothing extra.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
