WHY IT NEEDS A POLICY

Why queue_tracks needs a policy

Queuing tracks modifies the user's playback state but does not delete, execute arbitrary code, move money, or irreversibly alter data. It is a Write action because it creates/modifies data (the queue) in a reversible manner.

From the tool's definition The tool 'queue_tracks' explicitly 'Add tracks to your Spotify playback queue,' which modifies the playback queue state. This is a reversible write operation—queued tracks can be removed or skipped without permanent data loss.
