Agent Skills are SKILL.md files: Markdown instructions with a small YAML header that Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot, Windsurf and 60+ other agents load on demand. One format, every agent. What is an Agent Skill?
SkillMD is where they live. Every skill on skillmd.com is linted against the format, security-scanned for what it can do (scripts, network, secrets), pinned to a commit, and shown with its verdict and independent scanner results. Installing writes files and does nothing else.
