The agent works only from the approved brief and material review. It takes whatever topic, platform, audience, duration, language, tone and narration policy you already gave and asks for the rest. Before drafting it tests the idea against a short list that includes one core idea, evidence in the footage, audience tension, an emotional curve and the hook, turn, climax and aftertaste, then offers two or three distinct story directions and waits for your pick.
The draft uses short speakable sentences, leaves room for sound and silence, marks factual uncertainty, and ties each narrated beat to approved visual evidence or labels it as context you need to verify. It lists the scene sequence, narration intent, evidence references and rhythm notes, plus five title and hook options when publishing is in scope. The full draft appears in chat and is written to a file only after you approve. Platform versions are rewrites, not cuts, and two reference files hold a checklist and an ideation framework.
