What does this agent skill do?
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-dlpneeded)
Quick start
summarize "https://example.com"
summarize "/path/to/file.pdf"
summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto
YouTube: summary vs transcript
Best-effort transcript (URLs only):
summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto --extract
If the user asked for a transcript but it's huge, return a tight summary first, then ask which section/time range to expand.
