Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. It does disclose the scope of what is restored (instance transforms and material overrides), but says nothing about whether the undo is one-shot or repeatable, whether it requires an active session, or what happens on failure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
