What codex-review does

Two slash commands land in Claude. /codex-review:plan hands your implementation plan to Claude for critique, and Claude rewrites it around the feedback. /codex-review:code pulls the git diff from the current session and fixes what Claude flags. Rounds repeat until Claude approves.

You can pick the model per call: /codex-review:plan o4-mini. The default is gpt-5.3-codex, rounds are capped at five so the loop cannot run away, and Claude sits in a read-only sandbox — it reads your codebase but never writes to it.

Two things have to be in place first: Anthropic Claude CLI itself (npm install -g @openai/codex) and an Anthropic API key configured for it. No key means Claude never starts, so both commands have nothing to call. Claude must be installed and authenticated as well.

What it helps with

  • get a second model's take on a plan before writing code
  • review the git diff of the current session
  • close out Claude feedback without hand-editing the plan
  • catch weak spots in changes before committing
  • compare how two models read the same task

Example prompts for the agent

  • Send my implementation plan to Claude and revise until it approves: /codex-review:plan
  • Review the changes from this session with Claude: /codex-review:code
  • Run the code review with the o4-mini model: /codex-review:code o4-mini

</p>

## Prerequisites

- [**Claude Code**](https://docs.anthropic.com/en/docs/claude-code) — installed and authenticated
- [**OpenAI Codex CLI**](https://github.com/openai/codex) — `npm install -g @openai/codex`
- **OpenAI API key** — configured for Codex

## Installation

**Quick install** (run inside Claude Code):

```
/plugin marketplace add LuD1161/codex-review-skill
/plugin install codex-review@codex-review-marketplace
```

**Local / development**

```bash
claude --plugin-dir /path/to/codex-review-skill
```

## Usage

### Review a plan

```
/codex-review:plan
```

Send your implementation plan to Codex. Claude automatically revises the plan based on feedback until Codex approves.

### Review code changes

```
/codex-review:code
```

Gather the git diff from your session and send it to Codex. Claude automatically fixes issues Codex finds.

### Override the model

Both skills accept a model argument:

```
/codex-review:plan o4-mini
/codex-review:code o4-mini
```

## Configuration

| Option | Default | Description |
|:--|:--|:--|
| Model | `gpt-5.3-codex` | Override per-invocation via arguments |
| Max rounds | `5` | Prevents infinite review loops |
| Sandbox | `read-only` | Codex can read your codebase but never writes |
