About Claude skills

What is a Claude skill?

A skill is a folder with a SKILL.md file: a name, a one-line description of when to use it, and instructions (plus optional scripts and reference files). Claude reads only the description up front and loads the rest when a task needs it, so you can install many skills without filling the context window. Skills work in Claude Code, Claude.ai, the Claude app and the Claude API, and the same format is used by other agents such as Codex and Cursor.

How do I install a skill in Claude Code?

Copy the skill folder into ~/.claude/skills (for you) or .claude/skills in a project (for your team). If the repo is a plugin marketplace you can also run /plugin marketplace add owner/repo inside Claude Code and install it from /plugin. Every skill page here has the exact commands.

How is popularity measured?

Mostly by the GitHub stars of the repo the skill lives in, with forks, the number of curated awesome lists that include it, and the number of repos that carry a copy as smaller signals. Skills from a repo with hundreds of skills share that repo's stars, so they get a small penalty to keep one big collection from filling the list.

Where does this directory get its skills?

From Anthropic's official anthropics/skills repo, the largest community lists (VoltAgent, travisvn, ComposioHQ, BehiSecc, karanb192, heilcheng, skillmatic-ai and hesreallyhim) and a GitHub search for skill repos. Every SKILL.md in those repos is read for its name and description, and copies of the same skill are merged. It refreshes every day.

Are these skills safe to install?

Skills can include scripts that run on your machine, so treat a skill like any other code from the internet: read the SKILL.md and any scripts before installing, prefer official and well-starred repos, and check the license.

Sources: anthropics/skills (official), travisvn/awesome-claude-skills, ComposioHQ/awesome-claude-skills, VoltAgent/awesome-agent-skills, BehiSecc/awesome-claude-skills, karanb192/awesome-claude-skills, heilcheng/awesome-agent-skills, skillmatic-ai/awesome-agent-skills, hesreallyhim/awesome-claude-code, and GitHub search.
