What trigger_focused_next does on Propresenter
AI agents invoke trigger_focused_next 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 trigger_focused_next is rated High
