What its author says it does
Copied from the file, not written here
Plan, write, and publish for YouTube and YouTube Shorts. Use when the user wants high-CTR video titles, an SEO description with chapters and links, a first-30-seconds retention script (or a 3-second Shorts hook), a designer-ready thumbnail brief, a community-tab post or poll, or a weekly upload plan. The user supplies the video; the skills produce the title, description, hook, and thumbnail brief, then on approval upload and schedule via the Publora API.

YouTube Marketing Skills
A bundle of 9 focused skills for YouTube content ops in 2026, covering both long-form and YouTube Shorts. Each skill is single-purpose, follows the draft then approval then publish pattern, and uses the Publora API for uploading and scheduling the video you supply.
When to use this bundle
- Writing high-CTR titles (curiosity, number, how-I, comparison) with A/B variants -> use
yt-title-optimizer - Writing the description (first-150-char hook, chapters, keywords, links) -> use
yt-description-writer - Scripting the first 30 seconds for retention (or the first 3 seconds of a Short) -> use
yt-hook-scripter - Briefing a thumbnail (text overlay, face/emotion, contrast) plus the upload flow -> use
yt-thumbnail-brief - Writing a community-tab post or poll -> use
yt-community-post-writer - Planning a week of uploads (long-form vs Shorts mix, title/thumbnail pairing) -> use
yt-content-planner - Repurposing off-platform content (a blog post, thread, or LinkedIn post) into a YouTube community post or a video brief -> use
yt-repurposer - Auditing and rewriting the channel page (banner, trailer, About, playlists, section order) to convert viewers into subscribers -> use
yt-channel-optimizer - Reading your audience from the comments (who commented, themes, superfans, trending) -> use
yt-audience-insights
Core pattern
Every action-taking skill follows three steps:
- Parse the input. If the user gives a YouTube URL, the skill uses
lib/url_parser.pyto extract the video id, Short id, channel, or handle. - Draft the content. The skill applies 2026 research (title and hook formulas, CTR x retention heuristics, thumbnail principles, voice rules) and shows the draft to the user.
- Wait for approval. The user replies "publish", "yes", or suggests edits. Only after explicit approval does the skill upload and schedule via Publora.
Why YouTube is video-first (read this once)
YouTube is a video-only platform: every published post requires a single video file, which the user supplies. The skills write the title, description, hook script, and thumbnail brief; you bring the .mp4. On approval the upload follows the documented Publora flow:
create-postwith no scheduledTime -> creates a draft, returns apostGroupIdget-upload-url-> a pre-signed S3 URL- PUT your video to S3
update-post/:postGroupId-> set the scheduledTime (and any youtube settings)
A custom thumbnail is set after the draft exists, via update-post (the
thumbnail upload needs the postGroupId), never on create-post. YouTube
community-tab posts have no Publora endpoint, so yt-community-post-writer
always returns a copy-paste block.
Prerequisites
Three tiers - pick one.
Tier 0 - Draft only (default, no setup)
The skills work out of the box. No API keys, no signup. Every approved draft is returned as a copy-paste block (title + description, hook script, thumbnail brief, or community post) for you to use in YouTube Studio. Great for trying the skills before committing to any backend.
Tier 1 - Publora auto-upload (recommended, ~2 min)
On approval, the writer skills upload and schedule the video you supply via the Publora API.
- Sign up free: https://app.publora.com/signup
- Connect your YouTube channel in Publora (Channels then Add Channel, Google OAuth)
- Copy your API key from Publora's API panel
- Drop into
.env:PUBLORA_API_KEY=sk_... YOUTUBE_PLATFORM_ID=youtube-UC... - Run
pip install -r requirements.txt
Why Publora: uploading to YouTube on the native Data API means a Google OAuth flow, the resumable-upload protocol, and quota tracking. Publora does the draft, the S3 upload, the schedule, and the metadata in a handful of REST calls. We built on top of it so we did not have to reimplement the upload chain.
Tier 2 - Build your own uploader (advanced)
Prefer not to SaaS it? Ask Claude Code or Codex to build a custom uploader on the
YouTube Data API. Set YOUTUBE_SKILLS_CUSTOM_POSTER=<your command> and the
skills invoke it on approval. Publora is the 2-minute path.
Note on community posts
YouTube community-tab posts and polls have no Publora endpoint, and there is no
public API for them. So yt-community-post-writer always returns its draft as a
copy-paste block for you to post in the Community tab yourself. Videos and Shorts
upload and schedule through Publora normally.
Voice rules (baked into every skill)
- No em dashes (
—), en dashes, or double dashes. Biggest AI tell. - Use
..as a soft pause in a script line when rhythm calls for it. - Capitalize all personal, company, and product names.
- Specific numbers beat adjectives. "in 28 days" beats "fast".
- Title is a promise, not a summary. Curiosity plus a concrete payoff.
- Title and thumbnail are a pair. They never repeat the same words.
- The first 30 seconds (or 3 on a Short) is the real algorithm. No intro.
- Title caps at 100 chars (sweet spot 40 to 60). Description caps at 5,000, first 150 visible.
- Avoid AI vocabulary:
leverage,fundamentally,streamline,harness,delve,unlock,foster. - Do not keyword-stuff. Natural language with the real search phrase once.

How YouTube URLs map
| URL shape | Parsed to |
|---|---|
https://www.youtube.com/watch?v=VIDEO_ID | video_id, type video |
https://youtu.be/VIDEO_ID | video_id, type video |
https://www.youtube.com/shorts/VIDEO_ID | video_id, is_short: true, type short |
https://www.youtube.com/@handle | handle, type channel |
https://www.youtube.com/channel/UC... | channel_id, type channel |
lib/url_parser.parse_youtube_url(url) returns {video_id, handle, channel_id, is_short, url_type, canonical_url}.
Known gotchas
- A video is required. A text-only YouTube post is accepted by
create-postbut fails at publish withVIDEO_REQUIRED. Always use the draft -> upload -> schedule flow. The exception is a community post, which is not a video upload (and has no endpoint, so it is copy-paste). - Title defaults to empty. If you do not set
platformSettings.youtube.title, YouTube derives one from the first 70 chars of the content. Always set it. - Content becomes the description. The
contentyou pass is the video description; thetitleis separate inplatformSettings. - Thumbnail needs a postGroupId. It cannot be set on
create-post. Create the draft, upload the thumbnail (verified channel, JPEG/PNG <= 2 MB), thenupdate-post. The apply is best-effort: a rejected thumbnail does not block the video. - Publora caps uploads at 512 MB even though YouTube natively allows far larger. Compress or use the dashboard for bigger files.
- CTR is only half the product. A title that over-promises and loses the first 30 seconds is punished harder than a modest title. Pair every title with a hook that keeps it.
