Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is largely covered. The description adds a real behavioral fact not in the annotations: tiered permission requirements (team builder/team manager/org admin depending on node type). It does not, however, explain what 'move' changes beyond reparenting (e.g. effect on children, ordering, or downstream assignments).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
