Questions, answered.

What are Claude skills?

Claude skills (agent skills) are folders with a SKILL.md file that teach an AI agent how to do a specific task. The agent reads only the name and description until a task matches, then loads the full instructions, scripts and references.

How do I install a Claude skill?

Run npx skills add owner/repo in your project. The open skills CLI detects Claude Code, Cursor, Codex and 70+ other agents and installs to the right folder. In Claude on the web, upload the skill folder as a ZIP under Customize > Skills.

What are the best Claude skills right now?

By installs and GitHub stars: Matt Pocock's skills, Superpowers, Taste Skill, Caveman, Corey Haines' marketing skills, Anthropic's official skills and Garry Tan's gstack. Alyn ranks every skill live.

Do skills work in Cursor, Codex and other agents?

Yes. SKILL.md is an open standard. The same skill works in Claude Code, Claude, Cursor, OpenAI Codex, Gemini CLI, GitHub Copilot, Windsurf, OpenCode and many more.

Are Claude skills free?

Every skill on Alyn is open source on GitHub and free to install. Check each repository's license before commercial use.

Where do Alyn's numbers come from?

GitHub stars, forks and activity come from the GitHub API. Install counts come from the public skills.sh badges, which count installs made with the skills CLI. Both refresh live.
