What it does

Download Youtube is an agent skill from team-attention/stanford-cs146s-kr. YouTube 영상에서 오디오(MP3)와 자막(Transcript)을 다운로드합니다. yt-dlp를 사용하여 VTT 자막을 Markdown Transcript로 변환. 사용: /download-youtube <youtube-url

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Documents & Office. It works with YouTube. The repository describes itself as: Stanford CS146S: The Modern Software Developer - Korean Edition.

When your agent uses it

  • Documents & Office work in your project

Example prompts

  • “/download-youtube”

Requirements

  • Python 3

Workflow steps

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

  1. URL 분석 및 검증
  2. yt-dlp 설치 확인
  3. 메타데이터 및 챕터 추출
  4. 오디오 다운로드 (--transcript-only가 아닌 경우)
  5. 자막/Transcript 다운로드 (--audio-only가 아닌 경우)
  6. VTT → Markdown 변환 (챕터 기반 섹션 분할)
  7. INDEX.md 업데이트

What it can do on your machine

Read from SKILL.md and the folder at commit a13c516. 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

    Shell commands in SKILL.md call:

    • yt-dlp
    • pip

    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:

    • youtube.com

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

  • Credentials

    Names no API keys, tokens, secrets or passwords.

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

Context cost

Download Youtube loads about 1.4k tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 413 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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 413 words (~1,386 tokens).
