What is youtube-marketing?

A bundle of nine skills for planning, writing, and publishing YouTube videos and YouTube Shorts. YouTube Shorts are brief vertical videos, and the bundle uses Publora for uploading and scheduling videos you provide.

Use it for titles and A/B variants, descriptions with chapters and links, opening hooks, thumbnail briefs, community posts and polls, weekly upload plans, content repurposing, and channel-page audits.

It separates common YouTube tasks into focused workflows, so you can handle titles, descriptions, hooks, thumbnails, audience posts, and planning without designing each process yourself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00105	$0.02359
Opus 5.5	$0.00042	$0.00944
Sonnet 5.5	$0.00021	$0.00472
Haiku 4.5	$0.00011	$0.00236

Security

Grade A, and why

youtube-marketing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 13 executable files (lib/__init__.py, lib/_env.py, lib/approval.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.py to 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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
