Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description goes well beyond the annotations by disclosing concrete behavioral consequences: the share link stops working immediately, shared username and password are cleared, and widgets/data remain untouched. This aligns with destructiveHint=false and idempotentHint=true, adding valuable context about side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
