What is it?
oh-my-codex (OMX) is an open-source orchestration layer that wraps OpenAI's Codex CLI to add multi-agent coordination, persistent project memory, and structured development workflows. Instead of running a single Codex agent, OMX lets you spin up teams of specialized agents that work in parallel across isolated git worktrees, coordinating through a shared state system.
How does it work?
OMX provides canonical skills invoked with $-prefixed commands: $team for coordinated parallel execution, $ralph for persistent mode that keeps working until goals are verified complete, $ralplan for consensus planning, and $autopilot for fully autonomous execution. Under the hood, it uses durable tmux-based agent sessions, stores plans and logs in a .omx/ directory, and routes tasks through 33 specialized prompts organized across build, review, specialist, and product domains.
Why does it matter?
Single-agent coding assistants hit practical limits on complex projects. OMX lets developers decompose large tasks across specialized agent roles that work in parallel without conflicts. The git worktree isolation means agents can edit code simultaneously without stepping on each other.
Who is it for?
Developers using OpenAI Codex CLI who want structured multi-agent workflows.
