Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate this is a write operation (readOnlyHint=false) and not destructive (destructiveHint=false). The description adds minimal behavioral context by specifying the target is a 'previously deleted' campaign, but does not disclose potential side effects, permissions, or state changes beyond that.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
