Write a full YouTube video description under 5,000 characters with a first-150-character hook (the only part visible before Show more, and what shows in search and suggested), timestamped chapters, naturally placed keywords, links, and a clear call to action. Covers long-form and YouTube Shorts. Becomes the create-post content that publishes with the video. Use to write or rework a description. Not for the title (use yt-title-optimizer) or the spoken opening (use yt-hook-scripter).

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 Description Writer

The description does three jobs: it hooks the reader in its first 150 characters,
it feeds YouTube and Google search, and it organizes the video with chapters and
links. This skill writes all three layers.

## When to use

- User says "write the description for this video"
- User has a video and wants chapters, keywords, and links structured
- User wants the first 150 chars optimized for the search/suggested snippet
- User is about to upload and needs the `content` that ships with the video

## The three layers of a description

| Layer | Chars | Job |
|---|---|---|
| **Hook** | first ~150 | the only text visible before "Show more"; also the search/suggested snippet. Lead with the payoff or the question and the search phrase. |
| **Body** | ~150 to 1,000 | expand the value, restate the promise, place the main keywords naturally, link the key resource. |
| **Furniture** | rest, up to 5,000 | chapters, links, social, credits, hashtags. Skimmable, labeled. |

How to install

The exact contents, by fingerprint
mdr add sergebulaev/youtube-skills/yt-description-writer@sha256:f5b22646a166bea1

The 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.
