Title Lab: 7 Claude test viewers decide if they'd click your YouTube video (free Claude Code skill)

It's a free skill for Claude Code, and you don't need to write any code to use it. You copy a folder, prepare one input and type one line.

Who's on the panel

1. The Searcher: typed a search and scans the results for the one that answers it
2. The Home-Feed Browser: wasn't looking for anything and sees the thumbnail first
3. The Subscriber: already likes the channel and decides if this one is worth the time
4. The Skeptic: punishes clickbait and checks the video can back the package up
5. The Newcomer: new to the topic and lost by insider words
6. The Phone Glancer: sees the thumbnail the size of a stamp on a phone
7. The Competitor Grid: sees it next to five other videos on the same topic

Each one votes CLICK or SKIP, gives a gut-feel click-through guess for people like them, scores the package out of 10, and gives one reason and one fix. They don't see each other's answers: in Claude Code each one runs as its own Claude, with its own fresh context, all 7 at the same time.

What you get

A report short enough to fit in one screenshot:

• how many of the seven would click, and a score out of 10
• who you lose, and why
• 3 better titles (60 characters or fewer), each a different approach
• 3 thumbnail text options (4 words or fewer) and the best title and thumbnail pair
• if you give it 2 or 3 options, which one the viewers pick

The last line of the report says how the panel actually ran, so you always know whether you got 7 separate Claudes or one Claude doing 7 passes.

Before you start

• Claude Code. It works in the Claude desktop app (the Code tab) or in a terminal.
• A paid Claude plan or API credit. Claude Code needs a Claude Pro ($20 a month) or Max plan, or pay-as-you-go credit from the Claude Console. Each run starts 7 reviewers, so it uses more of your plan's usage than a single chat message.
• The skill folder. Download it free below. The skill file costs nothing; running it is what needs Claude Code.
• About 10 minutes for the first run, then a minute or two per run after that.

Step 1: Put the folder in place

Unzip the download. Copy the whole title-lab folder (not just the files inside it) into your Claude skills folder:

• Mac: ~/.claude/skills/ (in Finder press Cmd+Shift+G and paste ~/.claude/skills)
• Windows: C:\Users\YOUR-NAME\.claude\skills\ (paste %USERPROFILE%\.claude\skills into the File Explorer address bar)

If the skills folder doesn't exist yet, create it.

Step 2: Get your title and thumbnail ready

Export your thumbnail as an image (PNG or JPG) and copy your title. Write one line on what the video actually delivers.

Step 3: Run it

Open Claude Code and start a new session so it picks up the new skill. Then type /title-lab, then your title in quotes, then drag the thumbnail into the window so its path appears, then the line about the video. Press Enter. For example:

/title-lab "I Tried Every Budget Microphone Under $50" "/Users/you/Desktop/thumb.png" video: 6 mics tested, one clear winner

It takes a minute or two. If Claude asks for permission to read your files or to start the test viewers, say yes.

What it can't do

• The click-through numbers are gut guesses, not data. Real click-through depends on where YouTube shows your video and to whom. The report says this every time.
• It won't invent claims for your titles. Tell it what the video actually delivers so new titles stay honest.
• It can't see your YouTube Studio numbers. Compare its pick against your real click-through after you publish.

Using the Claude.ai chat app instead

You can upload the skill as a zip in the Claude.ai app (Settings, then Capabilities, then Skills). Chat can't start subagents, so there one Claude plays all 7 test viewers one after another. It still works, and the report's last line says so.
