Baoyu Youtube Transcript

What it does

When your agent uses it

• User asks to get YouTube transcript
• Download subtitles
• Video thumbnail
• Video cover image

Example prompts

• “get YouTube transcript”
• “download subtitles”
• “get captions”
• “/baoyu-youtube-transcript”

Requirements

• Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1Run with --list first if the user hasn't specified a language, to show available options
2. 2Always single-quote the URL when running the script — zsh treats ? as a glob wildcard, so an unquoted YouTube URL causes "no matches…
3. 3Default: run with --chapters --speakers for the richest output (chapters + speaker identification)
4. 4The script auto-saves cached data + output file and prints the file path
5. 5For --speakers mode: after the script saves the raw file, follow the speaker identification workflow below to post-process with speaker…

What it can do on your machine

Read from SKILL.md and the folder at commit 1567581. 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 7 files in scripts/ (TypeScript), which the agent can run.

  Shell commands in SKILL.md call:

  • npx
  • yt-dlp

  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
  • youtu.be

  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

Baoyu Youtube Transcript loads about 2.4k tokens when it runs. Until then it costs about 120 tokens; SKILL.md has 874 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~120

When it runs · the whole SKILL.md, loaded when a task matches

~2.4k

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

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.
