Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and readOnlyHint=false, but the description adds that this deletes a ROOT record (implying cascade/side effects), that it cannot be undone, and that a confirmation gate is enforced. That is meaningful context beyond the flags.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
