What editor_open_asset does on Godot

WHY IT NEEDS A POLICY

Why editor_open_asset needs a policy

Opening an asset in the editor triggers an external operation (launching/activating the Godot editor UI to display a specific asset), which goes beyond a simple read/query. It causes a side effect in the editor environment. The description is brief but 'open' implies an action that affects the editor state.

Verdict

editor_open_asset Rate-limited

editor_open_asset stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
