Overview

OMX wraps OpenAI Codex CLI with an `omx` launcher, skills such as `$deep-interview`, `$ralplan`, `$ultragoal`, `$team` and `$code-review`, and specialist roles. Plans, logs, memory and mode state are kept under `.omx/`, and team workers run in separate git worktrees, with tmux for the team runtime. Codex remains the execution engine; OMX adds scoped AGENTS.md guidance and an optional Codex plugin layout.

Who it is for: Codex CLI users wanting structured planning and parallel agent workflows

Strengths

Staged workflow: interview, plan, then durable execution with checkpoints in .omx/ultragoal
Team workers get dedicated git worktrees automatically; named worktrees isolate sessions
Installs with npm; omx doctor and omx exec smoke test check install and auth
Also ships a Codex plugin layout with marketplace metadata

Weaknesses

Tuned mainly for macOS/Linux; native Windows and Codex App get less support
Requires Codex CLI installed and authenticated; does not run standalone
--madmax disables Codex approvals and sandbox, so only use in trusted repos
Large skill and command surface; loading many skills bloats context

What it needs

no GPU
Needs Node.js 20+, OpenAI Codex CLI, tmux (macOS/Linux team runtime), git
Models: OpenAI Codex CLI models

How to choose

Check which agent it targets and whether it works with the version you run.
Read what it adds to every prompt; big rule sets cost tokens on each call.
Prefer add-ons you can turn off per project.
