Summarize

Quick Reference

Input	Command
URL/article	summarize “https://...” --model openai/gpt-4.1-mini
Local file	summarize “/path/to/file.pdf”
YouTube	summarize “https://youtu.be/...” --youtube auto
Extract only	summarize “URL” --extract-only

Quick start

summarize "https://example.com" --model openai/gpt-4.1-mini
summarize "/path/to/file.pdf" --model anthropic/claude-3-5-sonnet
summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto

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.
