Is the Youtube Downloader skill free?

Yes. The skill itself is free from ECNU-ICALK/AutoSkill. SkillProof publishes the install command and an independent test verdict at no cost.

How do I install Youtube Downloader?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Youtube Downloader with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Tested · Didn't pass
Tested: Jul 21, 2026
Environment: Claude Code 2.x (agent harness)

Located the skill at SkillBank/Common/AwesomeClaudeSkills/youtube-downloader/SKILL.md. The full recursive git tree and a raw fetch both confirm the directory ships ONLY SKILL.md — the scripts/download_video.py that every command in the body invokes returns HTTP 404. A full git clone + copy into a temp ~/.claude/skills reproduced this: the installed dir contained only SKILL.md, no scripts/ folder. yt_dlp imports fine locally, but with no script to drive it there is no artifact to run, so output could not be measured. Frontmatter parses correctly and the trigger description is precise; docs oversell by documenting a non-existent script in detail.

What Youtube Downloader does

A skill meant to download YouTube videos and audio via yt-dlp with quality/format options, triggering when a user asks to download, save, or grab a YouTube video. It is broken: the entire SKILL.md body invokes scripts/download_video.py, which does not exist in the repository, so no download can run.

How to install Youtube Downloader

# BROKEN: the referenced scripts/download_video.py is NOT in the repo (404). This
# installs SKILL.md but the skill cannot run — no downloader script ships with it.
git clone --depth 1 https://github.com/ECNU-ICALK/AutoSkill.git /tmp/youtube-downloader-src
mkdir -p ~/.claude/skills
cp -R /tmp/youtube-downloader-src/SkillBank/Common/AwesomeClaudeSkills/youtube-downloader ~/.claude/skills/youtube-downloader
# The dir contains ONLY SKILL.md. To make it functional you would have to write
# scripts/download_video.py yourself and `pip install yt-dlp`. Default output path is
# hardcoded to /mnt/user-data/outputs/ (a sandbox path).

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
