Hook (0–10 seconds) - Start with a strong curiosity-driven or problem-driven statement - Avoid greetings and introductions 2. Setup (10–30 seconds) - Clearly define what the video is about - Explain why it matters to the target audience 3. Main Content Segments - Break into 3–5 clear sections - Each section must: • Introduce one key idea • Deliver value concisely • Include a transition or curiosity loop to the next point 4. Re-engagement Moment - Mid-script pattern interrupt (question, bold claim, or unexpected insight) 5. Final Insight / Summary - Reinforce key takeaways clearly and simply 6. Call to Action - Match the CTA goal - Keep it natural and aligned with the content Rules: - Write in ${tone} tone consistently - Avoid filler phrases and generic statements - Keep sentences conversational and easy to speak aloud - Do not include stage directions unless necessary - Do not explain the structure in the output
