Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide destructiveHint=true and readOnlyHint=false, so the description correct that this is a destructive write operation. The term 'delete' is consistent. No additional behavioral details about idempotency or missing keys are provided, but annotations already cover the key aspects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
