What the Ninja checked

Safe to use, if you have Claude Code
  • ✓MIT license: free to use, even commercially
  • ✓4.6K stars and 1.4K forks on GitHub
  • ✓Plain code: 6 small Python scripts, standard library only, no internet, no passwords (the Ninja read each one)
  • ✓It never publishes or logs into your channel: it writes, you upload
  • !Not maintained: published Sep 16, 2026 and never updated; 13 fixes from other people are still waiting
  • !Word counts only see a to z: accented and non-Latin words are miscounted (the Ninja checked the code)
  • !Needs Claude Code and a terminal; the silence cutter also needs Whisper, and the trend finder needs yt-dlp

The safe way to use it

  • It only writes. None of the 11 skills publishes or logs into your channel. If anything asks for your Google password, stop.
  • Install from the right address: github.com/Jakeschincariol/youtube-agent-skill. There are over 1,400 forks out there, and a copy may have been changed.
  • Rules change. Music, Shorts and monetization rules move often; check YouTube Studio.
  • A score is not a promise. The hook and title scores help you pick; your viewers decide how the video does.
