At a glance

Downloads a single YouTube video with chosen quality, format or audio-only MP3 output, using a bundled Python script built on yt-dlp.

  • Works in 3 steps: Download video in 1080p as MP4 → Download audio only as MP3 → Download in 720p as WebM to custom…
  • Saving a YouTube video locally at a specific quality or format
  • SKILL.md covers Quick Start, Options, Complete Examples and How It Works, plus 1 more section
  • Runs Python scripts from its folder; calls python; reaches youtube.com

What it does

Running the bundled script with just a video URL downloads the best available quality as MP4 into /mnt/user-data/outputs by default, with the filename generated from the video title. Flags cover quality from best or worst down to 1080p, 720p, 480p or 360p, output format as mp4, webm or mkv, an audio-only mode that saves an MP3 instead, and a custom output directory.

Under the hood the script relies on yt-dlp, installing it automatically if it is missing, fetching the video's metadata before downloading, picking streams that match the requested quality and format, and merging separate video and audio streams when needed. Only a single video is downloaded at a time; a playlist URL is skipped rather than downloaded in full.

When your agent uses it

  • Saving a YouTube video locally at a specific quality or format
  • Extracting just the audio from a YouTube video as an MP3
  • Downloading a video to a custom output directory

Example prompts

  • “Download this YouTube video in 1080p as MP4.”
  • “Grab just the audio from this video as an MP3.”
  • “Save this video as WebM at 720p into ./downloads.”

Requirements

  • Python
  • yt-dlp (installed automatically by the script if missing)

Workflow steps

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

  1. Download video in 1080p as MP4
  2. Download audio only as MP3
  3. Download in 720p as WebM to custom directory

What it can do on your machine

Read from SKILL.md and the folder at commit be2a406. 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 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    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

YouTube Video Downloader loads about 668 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 234 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~668

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 234 words (~668 tokens).

“Download YouTube videos with full control over quality and format settings.”
