WHY IT NEEDS A POLICY

Why duplicate_clip needs a policy

This tool creates and modifies project state by duplicating MIDI clips across tracks, which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions. The blast radius is medium because misuse could add unwanted clips to a project, but changes are easily undoable in Ableton Live's undo system.

From the tool's definition Tool name 'duplicate_clip' combined with description 'Duplicate a MIDI clip to any other track + slot' indicates creation of new data (a copy of an existing clip) within the Ableton Live project.
