Overview

skills.sh is an open directory and CLI for reusable AI agent skills — modular procedural knowledge packages that enhance coding agents with capabilities like design systems, debugging workflows, security reviews, and more. Built by Vercel Labs, it lets developers install skills from any GitHub repo with a single npx skills add command. The directory indexes publicly available skills, ranks them by install activity, and runs routine security audits to surface trustworthy options. Skills work across OpenCode, Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, and 67+ other agents.

The Verdict

Who Should Use skills.sh?

Best For

  • Teams distributing reusable workflows across AI coding tools
  • Developers using multiple coding agents who want shared capabilities
  • Open-source maintainers publishing agent skills for the community
  • Platform engineers wanting CI/CD-friendly skill installation
  • Anyone extending Claude Code, Cursor, or Copilot with procedural knowledge

Not Ideal For

  • Developers using a single AI tool with no interest in skill sharing
  • Teams needing private, internal-only skill registries (not yet supported)
  • Non-coding AI workflows (this is developer-facing only)

What's Great

  • Single command installs skills from any GitHub/GitLab/git URL
  • Supports 70+ AI coding agents out of the box
  • Project-scoped installs can be committed to repos for team sharing
  • Security audits run on indexed skills via partner providers
  • Skills usable without installing — pipe output directly to an agent
  • Leaderboard tracks trending skills by 8-week install activity
  • Fully open-source CLI and ingestion pipeline

Watch Out For

  • No private registry support — all indexed skills are public
  • Skill quality varies since anyone can publish
  • Requires Node.js/npx — no standalone binary
  • Telemetry is opt-in, so install counts may undercount real usage
