Q: How do I install yt-package?

Run npx skills add https://github.com/jakeschincariol/youtube-agent-skill --skill yt-package in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/yt-package/ (personal) or .claude/skills/yt-package/ (project).

Write and lint the title and thumbnail for a YouTube video as one pairing, checking truncation, duplication and vagueness before publish. Use for "title ideas", "what should I call this", "thumbnail text", "my CTR is bad", packaging, or any request to rename or repackage an existing video.

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/jakeschincariol/youtube-agent-skill --skill yt-package

01
Install
Run the command in your project. The CLI asks which agents to install for.
02
Describe the task
Ask your agent for something this skill covers. It loads yt-package automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

yt-package

The title and the thumbnail are ONE unit. Writing them separately is why most packaging fails: the thumbnail repeats the title, and half the click surface says the same thing twice.

python3 title.py --title "..." --thumb "AI RAN IT"
python3 title.py titles.txt            # one per line, ranked

Before you write

Read ~/.claude/youtube/voice.md if it exists. That is the user's voice profile: how they talk on camera, the words they never use, who they are talking to, what they will not claim. If it does not exist, ask for three of their own videos, read or transcribe them, infer the voice, and write the file. A script in the wrong voice is worse than no script, because they have to read it out loud.
Never invent a number, a result or a source. If a figure would strengthen it and you do not have one, ask for it or write the line without it.

Rules the tool enforces, and why

60 characters is where desktop search truncates, 40 is a mobile home feed. Both are reported because they fail differently: a desktop cut loses the tail, a mobile cut can lose the subject.
The thumbnail must not repeat the title. Different words, same promise.
Three words maximum on the thumbnail. At feed size a fourth word is a grey smear.
A number, a name or a date beats every adjective available to you.
Two all-caps words is the ceiling before a title reads as spam.

Write ten, keep two

Generate ten titles, run them all through title.py, show the user the top three with their scores and the specific issue on each. For the winner, write the thumbnail brief: the expression, the framing, the three words, and what the background has to do to hold contrast at feed size.

The gate

Nothing here publishes. This skill writes and you publish. Every output ends in a block the user copies, and the last line of every run is the question: ship it, or change it?
