WHY IT NEEDS A POLICY

Why add_personality needs a policy

This tool creates or modifies music data in Ableton Live by adding personality-based musical styles to the session. This is a reversible write operation (can be undone in Ableton). While the description is empty, the context from sibling tools and the server's stated purpose of 'prompt-assisted music production' with personality styles strongly suggests data modification.

From the tool's definition Tool name 'add_personality' with sibling tools like 'add_personality_solo', 'add_blended_personality_solo', and 'add_arrangement_locator' that modify Ableton Live arrangements.
