AI agents invoke sonos_play_music_service_item to trigger actions in Sonos Ts. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool initiates playback on a physical Sonos device, which is an external operation with real-world effects (audio output). It is not merely reading or writing data, but executing an action that controls hardware. Misuse could disrupt audio environments but has limited blast radius beyond that.
