What it does

Video Downloader is an agent skill from kangarooking/kangarooking-skills. Download or open videos and recover platform captions, audio transcripts, keyframes, screen text, visual facts, and editing observations as a plain multimodaltranscript.md. Use for Douyin, Bilibili, YouTube, Xiaohongshu, experimental WeChat Channels links, or local video files when preparing complete source material for analysis or downstream Skill distillation.

Its SKILL.md is about 8.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 31 other files, including scripts (for example `THIRD_PARTY_NOTICES.md`, `scripts/artifact_metadata.py` and `scripts/asr.py`).

It sits in Media & Creative, covering Video production, Transcription and Messaging and chat bots. It works with Bilibili, WeChat, Xiaohongshu and YouTube. The repository describes itself as: My custom AI Agent skills.

When your agent uses it

  • Experimental WeChat Channels links
  • Local video files when preparing complete source material for analysis
  • Downstream Skill distillation

Example prompts

  • “/video-downloader”

Requirements

  • Python 3
  • A credential in SILICONFLOW_API_KEY
  • A credential in ARK_API_KEY

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Keyframes
  2. Complete video
  3. Agent clips (recommended)

What it can do on your machine

Read from SKILL.md and the folder at commit 08bbee0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 17 files in scripts/ (Python, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • python3
    • brew
    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • ark.cn-beijing.volces.com
    • weixin.qq.com
    • youtube.com
    • v.douyin.com

    Also links to:

    • volcengine.com
    • volcengine.github.io
    • github.com
    • siliconflow.cn
    • docs.siliconflow.cn

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • ARK_API_KEY
    • SILICONFLOW_API_KEY
    • WX_CHANNELS_API_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Video Downloader loads about 8.3k tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 3,761 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~96
When it runs · the whole SKILL.md, loaded when a task matches
~8.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 3,761 words (~8,290 tokens).
