yt-hook-scripter

---

name: yt-hook-scripter description: Script the spoken opening that decides retention: the first 30 seconds of a long-form YouTube video or the first 3 seconds of a YouTube Short. Uses 2026 patterns (restate-and-raise, cold-open payoff tease, question-and-contract, and the 3-second frame-one Shorts hook with a designed loop) to confirm the title's promise, open a loop, and earn the next 30 seconds with no intro. Use to write or fix a video opening. Not for the title (use yt-title-optimizer) or description (use yt-description-writer).

YouTube Hook Scripter

The packaging earns the click; the first 30 seconds (or 3 on a Short) earns the watch-time. This skill scripts that opening so the retention graph starts as a slope, not a cliff. It writes the words you say on camera, not the metadata.

When to use

• User says "write my intro" or "how should this video open"
• A video's retention drops hard in the first 30 seconds and needs a re-cut
• User has a Short and needs the first 3 seconds to stop the swipe
• User wants the spoken hook to match the title's promise

Formulas this skill uses (opening-hook shapes)

Code	Formula	Surface	Best for
Y7	Restate-and-Raise	long-form 30s	confirm the promise, raise the stakes
Y8	Cold-Open Payoff Tease	long-form 30s	flash the result, cut to the setup
Y9	Question-and-Contract	long-form 30s	answer fast, reopen a deeper loop
Y10	Shorts 3-Second Hook	Shorts 3s	state payoff/tension on frame one, loop the end

Steps

1. Gather inputs. The title (the promise to keep), the single payoff of the video, the most dramatic moment or result available for a cold open, the target viewer, and whether it is long-form or a Short. If a URL is given, parse it with lib/url_parser.py; is_short decides the surface.
2. Pick the surface.
   • Long-form: write the first 30 seconds, beat by beat, with rough timestamps.
   • Short: write the first 3 seconds (frame one), then the line that makes the ending loop back to the start.
3. Pick the formula. Use the pairing table in the hook-formulas reference: the title formula suggests the opening hook (a curiosity-gap title pairs with restate-and-raise; a how-I title pairs with a cold-open payoff tease).
4. Write the script. Spoken voice, one person to one person. For long-form:
   • Line 1 lands the title's promise in your own words (no greeting).
   • Line 2 raises the stakes or names the obstacle (opens the loop).
   • Line 3 makes the watch-contract ("by the end you will..").
   • Note where B-roll, a cold-open clip, or on-screen text goes. For a Short: one arresting frame-one line, on-screen text included, plus the loop line.
5. Strip the intro. Cut any "welcome back", logo sting, or channel-trailer reflex. The hook is the first thing the viewer hears.
6. Humanizer pass. Remove AI vocabulary, em dashes, and rule-of-three; use .. for a spoken pause instead of a dash.
7. Approval card. Show the scripted open with timestamps (long-form) or the 3-second frame plan (Short), and the title it is keeping.
8. On approval. This is a script the user performs; it is not published by itself. If the user uploads through this bundle, the hook is spoken in the video and the title/description ship via lib.publish(...).

Hard rules

Global voice rules: see root SKILL.md Voice rules. Additional skill-specific rules:

• No greeting, no intro animation, no logo sting before the hook. Ever.
• Long-form: the promise from the title is restated in the first 1 to 2 spoken lines, then a loop is opened. Earn the next 30 seconds by the 30-second mark.
• Short: the payoff or tension lands on frame one (second 0 to 1), with on-screen text so it works muted. Design the ending to loop back to the start.
• The opening can never promise more than the video delivers. Honor the click.
• Use .. for a spoken pause, never an em dash (it leaks into a teleprompter).

Anti-patterns (skill will refuse)

• "Hey guys, welcome back to the channel" or any greeting in the open.
• A 15-second intro animation before the first word of value.
• A cold open that teases a moment not actually in the video.
• "Make sure to like and subscribe" inside the first 30 seconds.
• Em dashes in a line meant to be read aloud.
• A Short that opens with a slow zoom or a logo instead of the payoff.
