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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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 | Full skeletons in `../../references/hook-formulas.md`. ## Steps …

How to install
mdr add sergebulaev/youtube-skills/yt-hook-scripter@sha256:4ac58ba0e2964002The line at the top of this page pins the label git:20261003.e922430, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
