what do people make with this?

VIBE 1

Add a skill to Claude Code so it can delegate coding subtasks to OpenAI Codex.

VIBE 2

Get a quick second opinion from Codex on a piece of code without leaving Claude Code.

VIBE 3

Run a longer steerable Codex session controlled through local files.

in plain english

This project is an add-on skill for Claude Code, the command line coding assistant from Anthropic. It teaches Claude Code how to call OpenAI's Codex command line tool as a helper, so Claude can hand off certain coding tasks to Codex and use its output as part of a larger workflow. The package is built around a skill folder named codex-subagent. Inside it, a SKILL.md file explains the rules Claude should follow when using Codex, and two Python scripts do the actual work. One script runs a single one-shot turn with the Codex app server, useful for quick tasks. The other script runs an interactive, file-controlled session with Codex, which lets a longer running conversation be steered through files on disk rather than a live terminal. To use this, you need Claude Code installed with support for local skills, the OpenAI Codex command line tool installed and already signed in, and Python 3.9 or newer on your machine. The setup does not configure Codex authentication for you, so that step has to be done separately before the skill will work. Installing the skill means copying or linking its folder into your personal Claude skills directory, then restarting Claude Code so it notices the new skill. Once installed, the SKILL.md file documents the supported patterns: asking Codex for a second opinion in a read only mode, giving Codex a bounded task where it can write files, resuming a previous Codex session, and running the steerable app server sessions mentioned above using a file based control system. This is a small, focused developer tool rather than a full application. It is meant for people who already use Claude Code and want to bring in Codex as a secondary agent for specific jobs, and the README is fairly short with no separate documentation site. It is released under the MIT License.
