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.

We split this skill into the rules it gives an agent

4 rules. 0 are common, 2 are distinctive, and 2 are very specific to this project.

  • 0

    Common

    Most of the 7 edited versions we read keep these.

  • 2

    Distinctive

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Read ~/.claude/youtube/voice.md if it exists.

    line 22
  2. Distinctive:

    Never invent a number, a result or a source.

    line 27
  3. Distinctive:

    Two all-caps words is the ceiling: before a title reads as spam.

    line 38
  4. Very specific:

    If they want it on the channel, /yt-publish is the only skill in this pack that touches YouTube, it uploads private unless they say …

    line 54

“Common” is measured: kept by at least 6 in 10 of the 7 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

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

  1. 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.
  2. 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 winning title is what /yt-publish takes as --title, so keep it under 100 characters or YouTube will not accept it at all.

The gate

This skill never publishes. Every output ends in a block the user copies, and the last line of every run is the question: ship it, or change it?

If they want it on the channel, /yt-publish is the only skill in this pack that touches YouTube, it uploads private unless they say otherwise, and it asks again before it does anything.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
