Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=false, and readOnlyHint=false, so the agent knows this is a destructive mutation. The description adds nothing beyond that – no warning about permanence, no note about the confirm requirement's authorization implications, no error behavior. With annotations carrying the safety profile, the description contributes no additional behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
