How to use
Open your terminal and run npx skills-lc-cli add to install a specific skill. For example, to add the architecture diagram skill, use npx skills-lc-cli add Cocoon-AI/architecture-diagram-generator . The skill will then be available in your supported AI agent (Claude Code, Codex CLI, Cursor, Windsurf, or Roo Code). Browse the Skills Leaderboard on the website to discover new skills by category (New, Trending, Hot, Favorites, All Time).
Effect review
AI Agent Sk delivers exactly what it promises: a massive, community-driven repository of reusable AI agent skills with straightforward installation. The 314.8K skills and 139.8M installs demonstrate strong community adoption, though the "Last 24h" count of 21 suggests most activity is historical rather than daily. The one-command npx installation is refreshingly simple, and compatibility with five major AI agents makes it broadly useful. For developers already using Claude Code, Codex CLI, or Cursor, this ecosystem eliminates the need to build agent skills from scratch. The leaderboard provides useful discovery, though the sheer volume of skills could benefit from better filtering or search—but that's a minor critique for an otherwise solid open platform.
