清空播放列表。
AI agents call clear_playlist to permanently remove resources in Xiaozhi — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes all items from a playlist, which is a destructive action that cannot be undone through the tool itself. While the blast radius is limited to playlist data rather than critical system resources, the permanent data loss nature classifies it as Destructive rather than Write. Severity is medium because the impact is scoped to user playlist content rather than system-wide or financial data.
From the tool's definition Tool name 'clear_playlist' combined with description '清空播放列表' (Chinese: 'Clear/empty the playlist') indicates irreversible deletion of playlist data without undo capability.
