These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Fix: Avoid sudo/root unless strictly required. Prefer least-privilege patterns. If elevation is needed, document the justification and scope.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

youtube-transcribe scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/batch_transcribe.py, scripts/transcribe.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

YouTube 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

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
