# axe — Agent eXtension Engine
Compile agent skills and rules across agentic coding platforms.
Write once in the AXE canonical format (Markdown + YAML frontmatter), compile to Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot, Cline, Windsurf, Continue, Zed, and Aider. Or use `axe compat` to convert between any two platforms directly.
