# Alyn

> Alyn ranks 2,394 agent skills (SKILL.md) from 124 GitHub repositories for Claude Code, Claude, Cursor, OpenAI Codex, Gemini CLI, GitHub Copilot and 70+ other AI agents. Rankings use live GitHub stars and skills.sh install counts (94M+ installs tracked).

Install any skill with the open skills CLI: `npx skills add <owner>/<repo>` (add `--skill <name>` for one skill, `-a <agent>` to pick an agent, `-g` for global). Claude Code also reads ~/.claude/skills/ and .claude/skills/. In Claude on the web, upload the skill folder as a ZIP under Customize > Skills.
