Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly=false, idempotent=true, destructive=false, and the description is consistent with that profile. It adds genuinely new behavioral context the annotations lack: the permission tier required for each node type (team processes, team proposals, areas), which is real auth-need disclosure. It stops short of saying what happens to the node's existing children or ordering on a move.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
