Oh My Codex, commonly known as OMX, is an open-source orchestration layer that converts the OpenAI Codex CLI from a single-agent coding assistant into a full multi-agent development platform. The core philosophy is that the developer acts as conductor rather than performer: OMX coordinates specialized agents for architecture, planning, execution, QA, and security review while Codex remains the underlying execution engine.
The platform introduces a staged pipeline model where tasks flow through plan, PRD, execution, verification, and fix phases with strict quality gates between each stage. Team mode spawns parallel workers in isolated git worktrees via tmux, enabling conflict-free concurrent development across multiple files or modules. The deep-interview workflow uses Socratic questioning to clarify requirements before any code is written, routing tasks to the appropriate workflow based on intent classification.
OMX ships with five MCP servers for persistent state and memory, a live HUD for monitoring agent activity, and a hook system for extending behavior at key lifecycle points. It supports mixed-provider teams where Codex, Claude, and Gemini workers run side by side, each in their own worktree. The project is MIT licensed, installs via npm, and integrates with the LobeHub skills marketplace.
