WHAT IT DOES

What scene_list_open does on Godot Breakpoint

AI agents call scene_list_open to retrieve information from Godot Breakpoint without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why scene_list_open is rated Low

This tool queries the state of the Godot editor to return a list of open scenes and metadata about them (current scene, unsaved changes status). It performs no mutations, side effects, or external operations. It is a straightforward read operation with minimal security impact—knowing which scenes are open poses negligible risk to a system.

From the tool's definition Tool name 'scene_list_open' and description explicitly states 'List the res:// paths' and 'Read-only.' The description confirms it retrieves information about open scenes without modifying state.
