Train Claude to write scripts for Instagram Reels, TikTok, YouTube Shorts and YouTube that people watch to the end. Hook rules (clarity + curiosity, the 4 hook killers, contrast), story arcs (the villain, rock bottom, the turn, the callback payoff), re-hooks every few seconds, anti-AI writing rules, engagement checks, the tools to use, and a checker that scores every draft. Claude drafts, scores and rewrites until the script passes. Use when someone asks for a script, a hook, a story, "write me a reel about X", "make this script better", "why did this video flop", or "break down this viral video".
