Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false and destructiveHint=false, so the mutation/safety profile is covered. The description adds the return shape ('Dict with success status') but discloses no side effects, prerequisites, or what current_task/on_behalf_of actually change behaviorally.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
