Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `CHANGELOG.md`, `references/douyin-nocookie-approach.md` and `scripts/download_douyin_note.py`).
It works with YouTube, Bilibili, Douyin and Spotify. The licence is MIT.
Read from SKILL.md and the folder at commit db2c58c. It shows what the files ask for, not the result of running them.
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.
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonpipbrewapt-getFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Universal Media Downloader loads about 1.2k tokens when it runs, and up to ~3.9k if it reads all its reference files. Until then it costs about 105 tokens; SKILL.md has 287 words of instructions outside code blocks.
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.
The automated check found patterns that need a careful read before installing.

Run `npx skills add cat-xierluo/legal-skills --skill universal-media-downloader -a claude-code`. Or copy the skill folder (skills/universal-media-downloader in cat-xierluo/legal-skills) into .claude/skills/universal-media-downloader in your project. Claude Code loads it when a task matches its description.
Run `npx skills add cat-xierluo/legal-skills --skill universal-media-downloader -a codex`. Or copy the skill folder (skills/universal-media-downloader in cat-xierluo/legal-skills) into .agents/skills/universal-media-downloader in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add cat-xierluo/legal-skills --skill universal-media-downloader -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/universal-media-downloader, .gemini/skills/universal-media-downloader, .github/skills/universal-media-downloader and .opencode/skills/universal-media-downloader in your project.
Going by SKILL.md and its folder, Universal Media Downloader needs Python for the scripts in its folder and the command-line tools its instructions call (python, pip, brew and apt-get). Our summary lists: Python 3.
SKILL.md contains no URLs. Its commands use pip, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md flagged 1 warning(s): mentions a credentials file (ssh keys, cloud or package-manager tokens). Read the flagged lines before installing; the check is not a guarantee either way. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Universal Media Downloader is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.2k tokens (SKILL.md is roughly 4.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2.7k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Universal Media Downloader: Video To Subtitle Summary (imlewc/video-to-subtitle-summary-skill, 218 stars), Video Podcast Maker (Agents365-ai/video-podcast-maker, 1.7k stars), Video To Notes (KIRVO-REPORTING/video-to-notes, 105 stars) and Video Copy Analyzer (ALBEDO-TABAI/video-copy-analyzer, 209 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
