WHY IT NEEDS A POLICY

Why manage_scene needs a policy

The name 'manage_scene' suggests creating, modifying, or managing scene files within the Godot game engine. In Godot, scenes are fundamental project components. 'Manage' implies both read and write operations, but since it likely creates or modifies scenes, Write is the most appropriate category.

manage_scene Rate-limited

manage_scene 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.
