A plugin for downloading YouTube videos, thumbnails, and subtitles with yt-dlp, with optional conversion, remote-server syncing, and Jellyfin library refreshes.

It is for downloading YouTube media, converting files to HEVC/AAC MP4 when needed, and optionally sending results to a media server.

It groups the YouTube media workflow into the coding agent and works locally without remote-server settings.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

yt-dlp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 25d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

{
  "name": "yt-dlp",
  "version": "1.0.0",
  "description": "Download YouTube videos, thumbnails, and subtitles with yt-dlp, transcode anything not natively Apple TV-compatible to HEVC/AAC MP4, and optionally sync the result to a remote media server over rsync/SSH with a Jellyfin library refresh. Use this skill whenever the user wants to download a YouTube video, grab a video's thumbnail, or asks to \"/ytdlp\" a URL. All remote-sync and Jellyfin settings are optional and configured per-machine via environment variables — with no configuration at all, it just downloads to a local folder."

Contents

What it installs

The manifest is a name and a version. 1 skill, 1 command travel with it, and installing the plugin installs all of them — 109 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
