WHAT IT DOES

What rhino_object_delete does on Rhino

AI agents call rhino_object_delete to permanently remove resources in Rhino, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why rhino_object_delete is rated Critical

Deletion of objects from a CAD document cannot be undone programmatically by this tool and represents a permanent loss of design work. This is the most severe category applicable. An AI agent misusing this could destroy significant user geometry and work, warranting high severity.

From the tool's definition Tool name 'rhino_object_delete' and description 'Delete the given objects from the document' explicitly indicate irreversible deletion of data from the Rhino document.

RECOMMENDED RULE

The rule that runs rhino_object_delete safely

rhino_object_delete Hidden

rhino_object_delete is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
