Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate destructiveHint=true, but the description adds specific details: it deletes connection data and makes data unavailable. It also discloses the return of an add_connection_url, which is not in annotations. This provides valuable behavioral context beyond the structured hints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
