Summarize or extract text/transcripts from URLs, podcasts, and local files (great fallback for “transcribe this YouTube/video”).

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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-outp

What does the summarize skill do?
Summarize or extract text/transcripts from URLs, podcasts, and local files (great fallback for “transcribe this YouTube/video”).
How do I install it?
Run `npx skills add SafeAI-Lab-X/ClawKeeper --skill summarize --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From SafeAI-Lab-X/ClawKeeper, a repository with 1,034 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
