Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=false, so safety is partly covered. However, the description adds nothing beyond the name: it does not say that removal is permanent, whether referencing agents/waypoints are also affected, or whether confirmation is expected. For an irreversible delete this is a meaningful gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
