Agent Skills

Skills are packaged instruction files that teach an AI coding agent a workflow or a piece of specialized knowledge. Agent Skills is a registry of them where nothing reaches the catalog without review. Each skill is plain text with no binaries, passes static analysis in CI, is pinned by lockfiles and content hashes, and is scanned with Snyk Agent Scan before publishing. The maintainers point to a figure of 13.4 percent of open marketplace skills carrying critical issues as the reason for curating by hand. The CLI installs skills into Claude Code, Cursor, GitHub Copilot, Windsurf, Antigravity, Codex, Gemini CLI and more than a dozen other agents, and an MCP server exposes the same catalog. The project is written in TypeScript and developed in the open on GitHub.
