Summarize

Fast CLI to summarize URLs, local files, and YouTube links.

When to use (trigger phrases)

Use this skill immediately when the user asks any of:

  • “use summarize.sh”

  • “what’s this link/video about?”

  • “summarize this URL/article”

  • “transcribe this YouTube/video” (best-effort transcript extraction; no yt-dlp needed)

YouTube: summary vs transcript

Best-effort transcript (URLs only):

Copy & paste — that's it
summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto --extract-only

If the user asked for a transcript but it’s huge, return a tight summary first, then ask which section/time range to expand.
