## Why add_audio_bus is rated Medium

This tool creates a new audio bus, which is a reversible modification to the project's audio configuration. It does not execute arbitrary code, delete data irreversibly, or cause financial impact. The 'add' operation is characteristic of Write category tools.

From the tool's own definition: "Tool name 'add_audio_bus' with description 'Add audio bus to layout' indicates creation of a new audio bus configuration in the Godot Engine project."

## Use case

AI agents use add_audio_bus to create or update resources in Godot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.
