WHAT IT DOES

What audio_focus_previous_playlist does on Propresenter

AI agents invoke audio_focus_previous_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.

RISK

Why audio_focus_previous_playlist is rated High

This tool triggers an action in ProPresenter (changing focus to a different audio playlist), which constitutes an external operation with side effects on the running presentation software. It doesn't read data, write/create content, delete anything, or involve finances. It executes a UI/state change in the application.

audio_focus_previous_playlist stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
