Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is known without the description. However, the description adds zero context beyond those flags — it does not say what gets destroyed, whether related objects cascade, or how to recover.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
