这个 skill 是干嘛的

ComposioHQ 在 66k stars 的 awesome-claude-skills 仓库里沉淀的"让 Claude 真的去操作外部 App"技能。每个 skill 对应一类外部集成(Gmail/Linear/Notion/Slack/Jira 等)。

michael 强调"skill 要有相应的指导功能,指导用户使用",所以加了下面两节让 Agent 和用户对接。

🤖 Agent 使用说明

1. 接到任务后先在脑里跑这个 skill 的 Checklist

2. 检查清单里如果提到"需要 X 凭证" → 调用前先 ask user 提供 X

3. 按 skill 流程一步步执行,不要跳步

4. 完工后跑 `verification-before-completion` 自检

👤 用户需要做什么?

1. 告诉 Agent 你要让 Claude 做什么(发邮件 / 建 issue / 发 slack / 等等)

2. 如果 Agent 反问"需要 API key / OAuth 授权",按提示在 Claude 对话框里点确认

YouTube Video Downloader

Download YouTube videos with full control over quality and format settings.

Quick Start

The simplest way to download a video:

python scripts/download_video.py "https://www.youtube.com/watch?v=VIDEO_ID"

This downloads the video in best available quality as MP4 to `/mnt/user-data/outputs/`.

Options

Quality Settings

Use `-q` or `--quality` to specify video quality:

• `best` (default): Highest quality available
• `1080p`: Full HD
• `720p`: HD
• `480p`: Standard definition
• `360p`: Lower quality
• `worst`: Lowest quality available

Example:

python scripts/download_video.py "URL" -q 720p

Format Options

Use `-f` or `--format` to specify output format (video downloads only):

• `mp4` (default): Most compatible
• `webm`: Modern format
• `mkv`: Matroska container

Example:

python scripts/download_video.py "URL" -f webm

Audio Only

Use `-a` or `--audio-only` to download only audio as MP3:

python scripts/download_video.py "URL" -a

Custom Output Directory

Use `-o` or `--output` to specify a different output directory:

python scripts/download_video.py "URL" -o /path/to/directory

Complete Examples

1. Download video in 1080p as MP4:

python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -q 1080p

2. Download audio only as MP3:

python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -a

3. Download in 720p as WebM to custom directory:

python scripts/download_video.py "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -q 720p -f webm -o /custom/path

How It Works

The skill uses `yt-dlp`, a robust YouTube downloader that:

• Automatically installs itself if not present
• Fetches video information before downloading
• Selects the best available streams matching your criteria
• Merges video and audio streams when needed
• Supports a wide range of YouTube video formats

Important Notes

• Downloads are saved to `/mnt/user-data/outputs/` by default
• Video filename is automatically generated from the video title
• The script handles installation of yt-dlp automatically
• Only single videos are downloaded (playlists are skipped by default)
• Higher quality videos may take longer to download and use more disk space
