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
summarize
"https://example.com"

YouTube: summary vs transcript
Best-effort transcript (URLs only):
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.
