Official Compound Engineering plugin for Claude Code, Codex, Cursor, and more
The Compound Engineering plugin is an official plugin for Claude Code, Codex, Cursor, and other AI coding agents that provides a collection of skills for engineering workflows. The project is built in Bun and TypeScript, with a CLI tool that converts the plugin between different agent platform formats (Claude Code, Codex, Cursor, and others) and maintains shared release and marketplace infrastructure. The repository serves as both the plugin source and the root for a marketplace catalog system, containing skills organized under `skills/`, platform-specific manifests, marketplace metadata, and comprehensive documentation for skill design and project conventions.
