About this skill
What does the youtube-summarizer skill do?

Extract transcripts from YouTube videos and generate comprehensive, detailed summaries. Use when summarizing video content or extracting key insights from YouTube.

How do I install it?

Run `npx skills add majiayu000/claude-skill-registry --skill youtube-summarizer-bcastelino-agent-skills-kit --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
