Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate destructiveHint=true and readOnlyHint=false. The description adds valuable context by clarifying that the operation does NOT delete contents, which nuances the destructive annotation. It also implies the action toggles an archived state, but does not detail side effects or confirmation requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
