WHY IT NEEDS A POLICY

Why create_playlist needs a policy

This tool creates new data (a playlist) in the user's Spotify account, making it a Write operation rather than Read. The severity is medium because while playlist creation is reversible (playlists can be deleted), it modifies user account state and could clutter the account or be used for spam.

From the tool's definition Tool creates a new playlist, which is a data modification operation. Description states 'Create a new Spotify playlist for the current user' — the verb 'create' indicates a write operation that adds new data to the user's account.
