Questions about Claude skills for AI agents

What is the best Claude skill for AI agents?

Our top pick is Find Skills by Vercel, from a repository with 38k GitHub stars. Skill Creator and MCP Builder round out the top three. Skills are ranked by the popularity of their source repository, with hand-picked favorites first, and official skills from Anthropic, Microsoft, Vercel and Google Labs carry a badge.

How do I install a Claude skill for AI agents?

Open a skill's page and run its install command in your project folder, for example npx skills add vercel-labs/skills --skill find-skills. You can also download any skill as a ZIP and add it to Claude Code or upload it to the Claude app.

The install guide walks through every method.

Are Claude skills for AI agents free?

Yes. All 41 skills on this page are open source and free to use, and most are MIT licensed. You need a Claude plan that supports skills, or a coding agent that reads SKILL.md files.

Do these skills work in Claude Code and the Claude app?

Yes. A skill is a folder with a SKILL.md file, and the same folder works in Claude Code, the Claude desktop and web apps (on paid plans with code execution turned on) and the Claude API. Many also work in other agents that support the Agent Skills format, such as Cursor and OpenAI Codex. Skills that ship scripts need somewhere Claude can run code.

How many Claude skills for AI agents are there?

We list 41 from 7 publishers, last updated November 4, 2026. The list refreshes from GitHub as publishers release new skills.
