What audio_trigger_focused_playlist does on Propresenter
AI agents invoke audio_trigger_focused_playlist to trigger actions in Propresenter. 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.
Why audio_trigger_focused_playlist is rated High
This tool executes an action (triggering/playing audio) whose outcome depends on system state (which playlist is focused). While not destructive or financial, it performs an external operation that changes the state of ProPresenter's audio system. Severity is medium because unintended audio playback during a presentation could disrupt a service or event, but the blast radius is limited to audio playback only.
From the tool's definition Tool name contains 'trigger' and description states 'Trigger the focused audio playlist' — indicates execution of an audio playback operation with external effects.
