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)

Quick start

2summarize "/path/to/file.pdf" --model google/gemini-3-flash-preview

YouTube: summary vs transcript

Best-effort transcript (URLs only):

bash
1summarize "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.
