WHAT IT DOES

What delete_selection_set does on Pypi:best Cad

AI agents call delete_selection_set to permanently remove resources in Pypi:best Cad, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_selection_set is rated Critical

This tool permanently removes entities from an AutoCAD drawing without the ability to undo through normal means in an automated context. Deletion of CAD geometry cannot be reversed by the tool itself and represents data loss. This is more severe than Write (which is reversible) and qualifies as Destructive due to its irreversible nature and potential to corrupt or destroy valuable engineering drawings.

From the tool's definition Tool name 'delete_selection_set' and description '删除指定选择集中的所有实体' (Delete all entities in the specified selection set) explicitly performs irreversible deletion of CAD entities.

delete_selection_set Hidden

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