Library Skill.md library

Skill.md files: teach Claude once, not every chat.

Each one names the GitHub repo it came from, so you can check exactly what it tells your AI to do.

How a Skill.md works

  1. A skill is a folder with a SKILL.md file of instructions, and sometimes scripts.
  2. You add the folder to Claude once.
  3. Claude loads it by itself whenever a task needs it.

Questions

What is a Skill.md file?

A folder of instructions, and sometimes scripts, that Claude loads when a task needs it, so you don't repeat yourself in every chat. Read the full explainer.

How do I add a skill to Claude?

Download the skill's folder, then upload it in Claude's settings, or put it in ~/.claude/skills for Claude Code.

Where do these skills come from?

Each one comes from a public GitHub repo, and its page names the owner, the repo and the licence.

Is it safe to install a skill that runs scripts?

Read the scripts first. Every skill page lists the files it can run on your machine before you install it.
