What youtube-summarizer does

The skill takes a video link or Shorts URL and retrieves captions via a local transcript module. It emulates an Android client. This avoids cloud IP bans on remote servers. The tool also extracts metadata like the author, view count, and publication date.

Output formats include a three-bullet quick summary, a default standard note, and a deep mode for content planning. The agent saves full transcripts to timestamped text files. It can also deliver files straight to Telegram.

Without the transcript server built at /root/clawd/mcp-server-youtube-transcript, this skill fails completely. It strictly requires Node.js and compiled scripts in the dist folder.

What it helps with

  • extract video captions from YouTube without manual copy-pasting
  • generate structured summaries with key insights and core takeaways
  • bypass cloud IP restrictions on VPS instances via Android client emulation
  • save timestamped transcripts and metadata directly to local files
  • deliver video transcript documents straight to Telegram

Example prompts for the agent

  • Summarize this video using quick mode: https://www.youtube.com/watch?v=VIDEO_ID
  • Analyze https://www.youtube.com/shorts/VIDEO_ID in deep mode to identify key content ideas
  • Extract the transcript from https://youtu.be/VIDEO_ID and save it to a local file

Questions about youtube-summarizer

How to install youtube-summarizer in Claude Code?

Run npx skills add BrianRWagner/ai-marketing-claude-code-skills --skill youtube-summarizer -a claude-code in your terminal. The skill file is placed in ~/.claude/skills/youtube-summarizer/SKILL.md.

Why use this skill instead of pasting transcripts into a web chat?

Most chat interfaces cannot access YouTube transcripts directly without third-party tools. This skill downloads captions and video metadata automatically in seconds.

What system dependencies must be configured before use?

You need mcp-server-youtube-transcript built inside /root/clawd/mcp-server-youtube-transcript. It requires Node.js and the compiled dist/youtube-fetcher.js script to fetch captions.
