Global Short-Form Video Script
Write 2 A/B script variants for TikTok / Reels / YouTube Shorts with hooks, CTAs, shoot guide, captions, hashtags, and a viral score.
Step 0 — Read context file
Before writing the script, read .agents/product-marketing-context-global.md for:
Product, USP, pricing
Target audience and core insight
Brand voice and tone
Region (drives language / cultural references)
If a personal-brand context file exists (e.g., .agents/personal-brand-context-global.md), ask which mode to use:
Mode A — Product: default, sell / convert
Mode B — Personal Brand: trust + authority (different hooks, soft CTA)
Information gathering
Ask the user up to 4 questions before writing:
Product / service? Short description, core USP, price (if relevant).
