Awesome Lists containing this project
- awesome-claude-code - Codex Skill - Enables users to prompt codex from claude code. Unlike the raw codex mcp server, this skill infers parameters such as model, reasoning effort, sandboxing from your prompt or asks you to specify them. It also simplifies continuing prior codex sessions so that codex can continue with the prior context. (Agent Skills 🤖 / General)

# 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.
