5 sections, as written by the authorYouTube 视频转录 + 翻译 Skill
字幕优先：先抓官方/自动字幕（秒级、免 GPU），抓不到再下载音频用 SenseVoice-Small 转录；英文内容自动翻译成中文，输出中英对照 Markdown。加 --no-subtitle 可强制走音频转录。
为什么需要这个
YouTube 有大量优质英文内容，但很多人没时间看完或语言不通。这个 skill：
- 转录视频为文字（支持中英文）
- 英文内容自动翻译成高质量中文
- 输出中英对照，方便学习
环境要求
# Python 3.9+
python -m venv .venv
source .venv/bin/activate
# 依赖
pip install funasr modelscope torch torchaudio
# 系统依赖
# macOS: brew install ffmpeg yt-dlp
# Ubuntu: sudo apt install ffmpeg && pip install yt-dlp
# 翻译功能（可选，英文视频需要）
export DEEPSEEK_API_KEY="your-api-key"
使用方法
python scripts/transcribe.py "https://www.youtube.com/watch?v=xxxxx"
python scripts/transcribe.py "https://www.youtube.com/watch?v=xxxxx" --output ./output
python scripts/transcribe.py "https://www.youtube.com/watch?v=xxxxx" --no-translate # 不翻译
python scripts/transcribe.py "https://www.youtube.com/watch?v=xxxxx" --no-subtitle # 强制音频转录
python scripts/batch_transcribe.py ../../examples/youtube-urls.txt -o ./output --no-translate
流程
Step 1: yt-dlp 下载音频
yt-dlp --extract-audio --audio-format mp3 --audio-quality 128K \
"https://www.youtube.com/watch?v=xxxxx"
Step 2: SenseVoice-Small 转录
from funasr import AutoModel
model = AutoModel(model="iic/SenseVoiceSmall", ...)
result = model.generate(input=audio_path, language="auto", use_itn=True)
Step 3: 语言检测 + 翻译
- 中文内容 → 直接输出
- 英文内容 → LLM 翻译成中文，输出中英对照
Step 4: 生成 Markdown

批量模式
scripts/batch_transcribe.py 支持 URL 列表批处理，默认单条失败后继续处理下一条；需要严格模式时加 --stop-on-error。
翻译配置
默认使用 DeepSeek API 翻译。需要设置环境变量：
export DEEPSEEK_API_KEY="your-api-key"
支持的 LLM：
- DeepSeek（推荐，性价比高）
- OpenAI
- 任何兼容 OpenAI API 格式的服务
性能数据
| 视频时长 | 下载 | 转录 | 翻译 | 总耗时 |
|------|------|------|------|------|
| 5 min | ~10s | ~5s | ~10s | ~30s |
| 10 min | ~15s | ~10s | ~20s | ~50s |
| 30 min | ~30s | ~30s | ~60s | ~2min |
已知限制
- SenseVoice-Small 对英文转录准确率不如中文
- 翻译质量取决于 LLM 能力
- 长视频翻译可能需要较长时间
- 部分 YouTube 视频有地区限制
参考项目
- yt-dlp/yt-dlp - 视频下载工具
- FunAudioLLM/SenseVoice - 语音识别模型
- DeepSeek - 翻译用 LLM

Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Improves the quality of images, especially screenshots, by enhancing resolution, sharpness, and clarity. Perfect for preparing images for presentations, documentation, or social media posts.
Downloads videos from YouTube and other platforms for offline viewing, editing, or archival. Handles various formats and quality options.
Lightweight WSI tile extraction and preprocessing. Use for basic slide processing tissue detection, tile extraction, stain normalization for H&E images. Best for simple pipelines, dataset preparation, quick tile-based analysis. For advanced spatial proteomics, multiplexed imaging, or deep learning pipelines use pathml.
Microscopy data management platform. Access images via Python, retrieve datasets, analyze pixels, manage ROIs/annotations, batch processing, for high-content screening and microscopy workflows.
Python library for working with DICOM (Digital Imaging and Communications in Medicine) files. Use this skill when reading, writing, or modifying medical imaging data in DICOM format, extracting pixel data from medical images (CT, MRI, X-ray, ultrasound), anonymizing DICOM files, working with DICOM metadata and tags, converting DICOM images to other formats, handling compressed DICOM data, or processing medical imaging datasets. Applies to tasks involving medical image analysis, PACS systems, radiology workflows, and healthcare imaging applications.
This skill should be used when working with pre-trained transformer models for natural language processing, computer vision, audio, or multimodal tasks. Use for text generation, classification, question answering, translation, summarization, image classification, object detection, speech recognition, and fine-tuning models on custom datasets.
How to use it
Take chubbyguan/youtube-transcribe from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
The instructions reference pip, brew.
Without those the skill loads but fails at the first command.
