What it does

Video Downloader is an agent skill from redfox-data/redfox-community. 短视频下载器 — 支持抖音、小红书、快手、视频号、B站、YouTube、Instagram 等主流平台无水印视频下载。

Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including assets (for example `README.en.md`, `README.md` and `assets/downloader.py`).

It sits in Media & Creative, covering Video production. It works with Instagram, YouTube, TikTok and X (Twitter). The repository describes itself as: 红狐数据(RedFoxHub) 技能合集:面向 Agent 的可复用 SKILL 集合,覆盖灵感、选题、文案创作、数据复盘等场景,持续更新。

When your agent uses it

  • Tasks that involve Video production

Example prompts

  • “/video-downloader”

Requirements

  • Python 3
  • A credential in REDFOX_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 6057a18. 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 script files (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    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:

    • youtu.be
    • instagram.com
    • v.douyin.com
    • xhslink.com
    • v.kuaishou.com
    • b23.tv
    • x.com
    • tiktok.com
    • threads.net
    • facebook.com
    • vimeo.com
    • weixin.qq.com
    • douyin.com

    Also links to:

    • redfox.hk

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

  • Credentials

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

    • REDFOX_API_KEY

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

Context cost

Video Downloader loads about 990 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 202 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~990

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); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 202 words (~990 tokens).
