name: youtube-asr-summarize description: "Summarize YouTube videos with NO subtitles by doing local ASR (yt-dlp + faster-whisper) and extracting a few screenshot frames via ffmpeg. Use when the user asks to summarize the latest video from a channel and YouTube timedtext/subtitles are empty, or when no API tokens/keys should be used."

YouTube ASR Summarize (local, no tokens)

Use this skill to summarize a YouTube video even when subtitles are missing by downloading audio and running local speech-to-text.

Quick start

1) One-time deps

brew install yt-dlp ffmpeg

2) Create venv + install ASR

python3 -m venv .venv
source .venv/bin/activate
pip install faster-whisper

3) Run

python3 scripts/youtube_asr_summarize.py \
  --url "https://www.youtube.com/watch?v=<id>" \
  --out "/tmp/youtube-asr/<id>" \
  --model small \
  --lang zh \
  --frames 1 \
  --timeline-every 180

Outputs in --out: - summary.md（含：链接 + 摘要 + 时间轴） - transcript.txt - transcript.srt - frames/frame_01.jpg … (if --frames > 0)

Notes

• Default model small (CPU/int8) is fast; use --model medium for better accuracy.
• If you need more control, see references/workflow.md.

这个工具能本地完成 YouTube 视频转写和总结，无需付费 API，隐私性好。功能流程完整，文档易读。缺点是摘要生成针对特定领域（中文金融）优化明显，对其他内容类型的总结效果可能不佳。另外缺少规范的依赖声明和测试，对普通用户不够友好。总体属于可用但需针对性使用的工具。
