Agent Skills are installable knowledge packages that give AI coding agents expert-level knowledge about specific topics. Unlike MCP servers that provide tools, skills provide context and best practices that agents use when writing code. Install them with npx skills add.
MCP servers give agents tools to perform actions (like creating a plan or tracking usage). Skills give agents expert-level knowledge on specific topics (like when to use metered vs credits billing). Combine both for the best results — tools plus the knowledge to use them correctly.
Skills work with any agent that supports SKILL.md files, including Cursor, Claude Code, Codex, Gemini CLI, GitHub Copilot, OpenCode, and Windsurf.
