Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and readOnlyHint=false, so the agent knows this is a destructive operation. The description simply repeats that it deletes, which aligns with annotations. No additional behavioral context (e.g., irreversibility, permissions) is provided beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
