What rhino_undo does on Rhino

AI agents use rhino_undo to create or update resources in Rhino, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rhino environment.

Why rhino_undo is rated Medium

While undo can revert destructive actions, it is itself a reversible modification tool—not destructive, since undo operations themselves can be undone (via redo). It falls under Write rather than Destructive because the modification is intentionally reversible. The severity is medium because an AI agent repeatedly calling undo could erase user work, but the user can undo the undo, mitigating full data loss.

From the tool's definition The tool name 'rhino_undo' and description 'Undo the last operation(s) in the Rhino document' indicate it modifies the state of the Rhino document by reverting changes. Undo is a reversible operation that alters document state.
