Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description usefully adds that all entity data is removed, but it says nothing about irreversibility, required permissions, or confirmation needs. It adds one meaningful detail beyond the annotations, not rich 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.
