Why editor_duplicate_node is rated Medium
This tool creates a copy of an existing node along with its children, scripts, and signals. It is a creation/write operation — it adds new data to the scene tree — but does not delete or overwrite anything, making it reversible (the duplicate can be removed). It does not execute code or move money.

The rule that runs editor_duplicate_node safely

editor_duplicate_node stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every editor_duplicate_node call is checked against it from then on.
