How a Skill differs from MCP

MCP = the hands

Connects the AI to an outside service or data, such as reading Notion or creating an invoice. A program or server has to be running.

Skill = the manual

A text file that teaches the AI how to do a task. It connects to nothing.

Some overlap: a few Skills run scripts that call tools, and a few MCP servers only send knowledge. Start from the task you want done.

Is it safe?

  • Who made it

    GitHub account aiming-lab (organization), 2 years old

  • Use and upkeep

    ★ 14,878 stars · code last changed Aug 19, 2026

  • Any scripts?

    No, plain text files the AI reads and follows

  • Uses the internet?

    No scripts, so it does not go online by itself

  • Changes machine-wide settings?

    No hooks or writes to machine settings found

Checked automatically from the repo files at commit be4ba47 (read only, nothing was run). Not a safety guarantee: read it and decide for yourself

First: which AI do you use?

Pick your app and this page shows only how to install it there

Option 1Upload to claude.ai (web and app)

  • Files are byte-for-byte the same as on GitHub at commit be4ba47 · View on GitHub ↗

  • Plain text files, no programs

  • Once uploaded it runs on Claude’s systems, not on your computer. No need to unzip

  3. No Upload button? Turn on file creation first

    SettingsCapabilitiesCode execution and file creation

    Turn on Code execution and file creation first (newer menus: Create and edit files) · personal plans: Settings → Capabilities · Team/Enterprise: an admin turns it on under Organization settings → Plugins & skills · every plan, including Free

Upload once; it works in claude.ai and Claude Desktop, and in recent Claude Code signed in with a Claude account (not with an API key)

Cowork and cloud sessions use the skills turned on in your claude.ai account, not ~/.claude/skills on your computer (Claude Desktop scheduled tasks run locally and still load it)
