What it does

Once installed, the agent can run a command-line tool called summarize to read a web link, a local file such as a PDF, or a YouTube video and return a short or detailed summary. For YouTube links it can also try to pull out a transcript. The skill tells the agent when to use the tool, which flags to pass, and which API keys are needed for the AI model that writes the summary.

Great for

  • People who want quick summaries of long articles, reports or videos
  • Anyone who needs a transcript of a YouTube video without installing yt-dlp
  • Users who already have an OpenAI, Anthropic, xAI or Google API key

Skip it if

  • Confidential or sensitive documents, because content is sent to a third-party AI provider and possibly to Firecrawl or Apify (the skill does not describe data handling)
  • Situations needing guaranteed-accurate transcripts, since transcript extraction is described as best-effort
  • Offline use, since the tool needs internet access and a model API

Try asking

  • “Summarize this article: https://example.com/post”
  • “What's this YouTube video about? https://youtu.be/...”
  • “Transcribe this YouTube video and give me the key points”
  • “Summarize the PDF at /path/to/report.pdf in short form”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Use --length short for a quick overview, and --extract-only when you want the raw transcript for URLs
  • Set a default model in ~/.summarize/config.json to avoid passing --model every time
  • Keep API keys in environment variables rather than pasting them into chat
