Summarize

Fast CLI to summarize URLs, local files, YouTube links, podcasts, and audio/video files.

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"
summarize "/path/to/file.pdf"
summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto
summarize "/path/to/podcast.mp3" --transcriber auto

YouTube: summary vs transcript

Best-effort transcript/extraction:

summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto --extract
summarize "/path/to/podcast.mp3" --transcriber 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.

Model + keys

Set the API key for your chosen provider:

• OpenAI: OPENAI_API_KEY
• Anthropic: ANTHROPIC_API_KEY
• xAI: XAI_API_KEY
• Google: GEMINI_API_KEY (aliases: GOOGLE_GENERATIVE_AI_API_KEY, GOOGLE_API_KEY)

Default model is auto if none is set; pass --model <provider/model> only when a specific provider is needed.

Useful flags

• --length short|medium|long|xl|xxl|<chars>
• --max-output-tokens <count>
• --extract (print extracted content/transcript and exit)
• --json (machine readable)
• --firecrawl auto|off|always (fallback extraction)
• --youtube auto|web|no-auto|yt-dlp|apify
• --transcriber auto|whisper|parakeet|canary (audio transcription)
• --video-mode auto|transcript|understand
• --slides, --slides-ocr, --slides-max <count> (slide-heavy videos)
