How to check a title and thumbnail together before upload with ChatGPT YouTube Agent Skill

Lint the title and thumbnail as one pairing so they do not repeat each other.

  • Content
  • Intermediate
  • 15 minutes
  • From the README
  • Codex

Who it is forA creator who has a finished video and wants a stronger click surface before publishing.

The problemTitles and thumbnails written separately often say the same thing twice, which wastes part of the click surface.

The outcomeA review of the title and thumbnail as a pair, with notes on repeated wording and gaps.

What you need first

  • ChatGPT or the Codex app that loads skills from ~/.codex/skills/
  • git installed, if you use the clone option
  • Python 3 to run the bundled scripts (the README says they need no packages)
  • Your own channel data, such as an audience-retention export, for the analysis skills

Steps

  1. Install the skills from the README link or with the git clone and copy commands.
  2. Restart the app.
  3. Paste your draft title and describe or attach your thumbnail.
  4. Ask the yt-package skill to lint the title and thumbnail as one pairing.
  5. Run python title.py on your title text for a quick local check. (inferred, check the README)

Prompt for your agent

Using the chatgpt-youtube-agent-skill repo, run the yt-package skill on the title <title-text> and the thumbnail description <thumbnail-description>. Expected output: a pairing review that flags any wording the title and thumbnail share. Verify that the review addresses both the title and the thumbnail.

Caveat. The README covers linting the pairing but does not say the skill checks the thumbnail image itself, so describe it in words when you ask.
