What this skill does
# 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 ```bash summarize "https://example.com" --model google/gemini-3-flash-preview summarize "/path/to/file.pdf" --model google/gemini-3-flash-preview summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto ``` ## YouTube: summary vs transcript Best-effort transcript (URLs only): ```bash 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. ## 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 `google/gemini-3-flash-preview` if none is set. ## Useful flags - `--length short|medium|long|xl|xxl|<chars>` - `--max-output-tokens <count>` - `--extract-only` (URLs only) - `--json` (machine readable) - `--firecrawl auto|off|always` (fallback extraction) - `--youtube auto` (Apify fallback if `APIFY_API_TOKEN` set) ## Config Optional config file: `~/.summarize/config.json` ```json { "model": "openai/gpt-5.2" } ``` Optional services: - `FIRECRAWL_API_KEY` for blocked sites - `APIFY_API_TOKEN` for YouTube fallback
