Documentation is essential but most people don’t read it. Video walkthroughs get significantly more engagement — but recording, editing, and keeping them in sync with doc changes costs more than most teams can justify.
Doc changes → LLM writes a video prompt → Video Agent renders → Embed or distribute
You don’t send docs directly to Video Agent. An LLM converts documentation into a structured video prompt — acting as a video producer who reads the source material and writes production direction.

Generate a video prompt with an LLM
import anthropicclient = anthropic.Anthropic()message = client.messages.create( model="claude-sonnet-4-20250514", max_tokens=1024, messages=[{ "role": "user", "content": f"""You are a video producer.

The two-stage pattern: Content → LLM (writes production prompt) → Video Agent (renders). The LLM bridges the gap between “what the docs say” and “what the video should show.”
