Oh My Claude Code 🤖 Agent Open source

What it does

Oh My Claude Code is a Claude Code plugin that turns Claude into a conductor for a small team of AI workers. It launches Claude, Gemini and Codex CLI processes in parallel tmux panes and coordinates them through 19 specialized agents, dozens of skills and MCP-backed tools, aiming for "no manual intervention required" runs from a stated goal to tested code.

Tools it gives your agent

• 19 agents grouped into build & analysis, review & quality, and domain specialists
• Multiple execution modes: Autopilot, a persistence mode called Ralph, Execute, Deep Interview, Team and Planning workflows
• MCP-powered tools: language server integration, AST-Grep for structural code search, a Python REPL and persistent state management
• Remote approval gates with workspace checkpoints and rollback for staged changes that need sign-off before landing

Works with

This is a Claude Code plugin specifically; it shells out to Gemini and Codex CLIs as additional workers, but Claude Code is the environment it installs into and the one it's built and tested against.

How to install or connect

/plugin marketplace add https://github.com/Yeachan-Heo/oh-my-claudecode
/plugin install oh-my-claudecode

Or via npm:

npm install -g @yeachan-heo/oh-my-claudecode

Then run /oh-my-claudecode:omc-setup to finish configuration.

Maintenance and safety

Very active and fast-growing (39,000+ stars, weekly commits, MIT licensed). Because it runs multiple CLI agents with shell and file access in parallel, review its approval-gate settings before pointing it at a repo you care about.

Who should use it

Claude Code users who want to run larger, multi-step jobs (architecture review, security analysis, multi-file refactors) across several models at once instead of a single linear session.
