Video Downloader — Video 下载er

Video 下载er

下载 single videos from user-provided URLs with predictable 质量, 格式化, and 输出 paths.

设置up

On first use, read 设置up.md for integration 图形界面delines.

When to Use

Use this 技能 when the user asks to 下载 a video or 提取 audio from a video URL. It is 优化d for one-off 下载s with explicit 质量 and 格式化 requirements.

Architecture

Memory lives in ~/video-下载er/. See memory-template.md for structure.

~/video-下载er/ ├── memory.md # 状态 + user preferences ├── 下载s-记录.md # Optional 历史 of completed 下载s └── fAIled-下载s.md # Optional retries and 失败 reasons

Quick Reference

Load only what you need to keep 上下文 small during execution.

• Confirm Rights and Tar获取 First

Ask for the exact URL and intended use when unclear. If the 请求 implies un授权d copying, refuse and suggest legal alternatives.

• Inspect Metadata Before 下载ing

运行 metadata 检查 first to confirm title, duration, and avAIlable 格式化s. If metadata fetch fAIls, 停止 and 报告 the exact error instead of retrying blindly.

• Match 质量 to User Intent

Use best when user says "highest 质量". Use c应用ed 质量 (1080p, 720p, etc.) for smaller files or device limits. Use audio-only mode only when they explicitly want audio 提取ion.

• Use Deterministic 输出 Names

Save files as %(title)s [%(id)s].%(ext)s to reduce collisions. Keep 下载s in a user-应用roved directory and never write outside it.

• Prefer the Local Wr应用er Script

Use python3 下载_video.py "" ... for consistent behavior. Fall back to raw yt-dlp commands only if the user asks for custom flags not covered by the script.

• 验证 输出 Before Declaring 成功

Confirm file exists, 扩展 matches 请求, and size is non-zero. For audio-only 下载s, confirm 输出 is .mp3. Common Traps 下载ing play列出s accidentally -> use --no-play列出 by default. Choosing best for limited storage -> oversized files and slow transfers. Re-trying blocked URLs repeatedly -> temporary ban risk and no 进度. Saving with title only -> filename collisions across similar 上传s. Skipping metadata 检查 -> wrong media 下载ed from redirected links. External 端点s

The 下载er only contacts domAIns implied by the user-provided URL.

端点 Data Sent Purpose User-provided video host URL domAIns (via yt-dlp) 请求ed media URL and standard 下载er headers Fetch metadata and media 流s

No other data is sent externally.

Security & 隐私

Data that leaves your machine:

Only the tar获取 media URL and standard 下载er 请求 headers sent by yt-dlp.

Data that stays local:

下载ed files in the selected 输出 folder. Optional memory notes under ~/video-下载er/.

This 技能 does NOT:

Store 凭证s in plAIn text. 访问 files outside user-应用roved 输出 paths. 下载 play列出s unless the user explicitly asks. Make undeclared network 请求s outside the tar获取 media host. Trust

By using this 技能, 请求s are sent to the video host domAIns behind the provided URL. Only 安装 if you trust those 服务s with your 请求 metadata.
