WHAT IT DOES

What arrangement_add_automation_point does on Ableton Mind

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

WHY IT NEEDS A POLICY

Why arrangement_add_automation_point needs a policy

This tool creates new automation data in Ableton Live's arrangement by adding parameter points. It is reversible (points can be removed or edited), so it is Write rather than Destructive. The effect is limited to the current project's automation state, affecting only music production parameters within the DAW, yielding medium severity.

From the tool's definition Tool description states 'Add one automation point' and 'repeated calls add more points' — creates new data points in the arrangement; 'returns the written time/value/curve after the bridge accepts it' confirms the write operation completes with persistence.
