WHAT IT DOES

What back_to_arranger does on Livepilot

AI agents invoke back_to_arranger to trigger actions in Livepilot. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why back_to_arranger is rated High

This tool triggers an external operation in Ableton Live — switching the playback mode from session view to arrangement view. It causes a state change in the DAW's playback engine, which qualifies as Execute. The blast radius is low since it only affects playback routing with no data creation, deletion, or financial impact.
