# 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
Download this repo and store the skill in ~/.claude/skills/codex
```
git clone --depth 1 git@github.com:skills-directory/skill-codex.git /tmp/skills-temp && \
mkdir -p ~/.claude/skills && \
cp -r /tmp/skills-temp/ ~/.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` or `gpt-5-codex`) unless already specified in your prompt.
2. Ask which reasoning effort level (`low`, `medium`, or `high`) unless already specified in your prompt.
3. Select appropriate sandbox mode (defaults to `read-only` for analysis)
4. Run a command like:
```bash
codex exec -m gpt-5-codex \
--config model_reasoning_effort="high" \
--sandbox read-only \
--full-auto \
--skip-git-repo-check \
"Analyze this Claude Code skill repository comprehensively..." 2>/dev/null
```
**Result:**
Claude will summarize the Codex analysis output, highlighting key suggestions and asking if you'd like to continue with follow-up actions.
