Codex Integration for Claude Code

Purpose

Enable Claude Code to invoke the Codex CLI (`codex exec` and session resumes) for automated code analysis, refactoring, and editing workflows.

Prerequisites

• codex CLI installed and available on PATH.
• Codex configured with valid credentials and settings.
• Confirm the installation by running codex --version; resolve any errors before using the skill.

Installation

This repository is structured as a [Claude Code Plugin](https://code.claude.com/docs/en/plugins) with a marketplace. You can install it as a **plugin** (recommended) or extract it as a **standalone skill**.

Option 1: Plugin Installation (Recommended)

Install via Claude Code's plugin system for automatic updates:

/plugin marketplace add skills-directory/skill-codex
/plugin install skill-codex@skill-codex

Option 2: Standalone Skill Installation

Extract the skill folder manually:

git clone --depth 1 git@github.com:skills-directory/skill-codex.git /tmp/skills-temp && \
mkdir -p ~/.claude/skills && \
cp -r /tmp/skills-temp/plugins/skill-codex/skills/codex ~/.claude/skills/codex && \
rm -rf /tmp/skills-temp

Usage

Important: Thinking Tokens

By default, this skill suppresses thinking tokens (stderr output) using `2>/dev/null` to avoid bloating Claude Code's context window. If you want to see the thinking tokens for debugging or insight into Codex's reasoning process, explicitly ask Claude to show them.

Example Workflow

**User prompt:**

Use codex to analyze this repository and suggest improvements for my claude code skill.

**Claude Code response:** Claude will activate the Codex skill and:

1. Ask which model to use (gpt-5.4, gpt-5.3-codex-spark, or gpt-5.3-codex) unless already specified in your prompt.
