Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It does disclose that the operation is bulk-destructive ('every part'), but says nothing about reversibility, undo, confirmation, whether the craft must be in an editable state, or what happens afterward. That leaves significant gaps for a destructive bulk operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
