codex-plugin-cc: install Codex Plugin for Claude Code.
If you searched for codex-plugin-cc, you likely want the official Codex Plugin for Claude Code, the exact install commands, and the shortest path to a clean local setup. This page keeps those jobs in one place: install, configure, run review, choose rescue when needed, and fix the common setup blockers.
The plugin follows the same user-level and project-level Codex configuration you already use locally.
Review is the default pass, adversarial review raises the bar, and rescue is the handoff path.

Requirements
What you need before installing codex-plugin-cc.
The install itself is short. Most failed setups come from missing local prerequisites, incomplete authentication, or confusion about where Codex configuration actually lives.
- Claude Code installed locally
- Node.js 18.18 or later
- A ChatGPT subscription or an OpenAI API key
- A local Codex install if setup does not install it automatically

Install
How to install Codex Plugin for Claude Code.
The fastest install path is to add the marketplace, install the plugin package, reload Claude Code, and run /codex:setup. If Codex is not installed locally, setup may prompt for it. If it is installed but not authenticated, finish local auth first and rerun setup.
Add the marketplace source
Register the marketplace that publishes the Codex plugin so Claude Code knows where to install it from.
/plugin marketplace add openai/codex-plugin-ccInstall the plugin package
Install the Codex plugin inside Claude Code so the Codex slash commands become available in your local workflow.
/plugin install codex@openai-codexReload and verify setup
Reload plugins, then let setup check whether Codex is installed, authenticated, and ready to answer through the plugin.
/reload-plugins /codex:setup
First runCheck the review loop
/codex:review --background
/codex:status
/codex:resultConfigure
Configure codex-plugin-cc through your local Codex settings.
The plugin is easiest to manage when you treat it as a consumer of your existing Codex environment. Instead of hunting for a plugin-only config layer, keep user defaults and project overrides in the same Codex files you already control.
User defaults
User defaults
Keep your personal Codex defaults in ~/.codex/config.toml so every project starts from the same baseline.
Project overrides
Project overrides
Add .codex/config.toml in the repo when this project needs different model or reasoning settings than your global defaults.
Trusted projects only
Trusted projects only
Project-level Codex configuration loads only after the current repository is trusted, so local overrides stay explicit.
.codex/config.tomlExample local override
model = "gpt-5.4-mini"
model_reasoning_effort = "high"Commands
Which codex-plugin-cc command to use and when.
Most Claude Code users do not need every command at once. They need the right command for the current risk level: normal review for standard work, adversarial review for high-stakes changes, and rescue when they want a direct Codex handoff.
/codex:review
Use for the normal second pass
Start here when you want Codex to inspect uncommitted work, compare a branch, or provide a second opinion without changing files.
/codex:review --background/codex:adversarial-review
Use for high-risk decisions
Run this when migrations, authentication, refactors, caching, or infra choices need a more skeptical review that challenges assumptions.
/codex:adversarial-review --background question the auth boundary and rollback plan/codex:rescue
Use for direct handoff
Choose rescue when the current thread stalls, when a fix needs another agent to take over, or when you want Codex to investigate independently.
/codex:rescue trace why setup keeps failing after reloadReview gate
Use a forced review loop only when you explicitly need one.
A review gate can be useful, but it should be intentional. It is better for sensitive or high-risk changes than for routine work, because a forced loop can increase latency and usage quickly if it stays too broad.
Use it for sensitive changes
Tighten the loop for risky deploys, fragile migrations, or code where you want Claude Code blocked until Codex has completed a targeted pass.
Keep the review scope narrow
The more specific the request, the easier it is to get a useful review without turning the workflow into an expensive or noisy loop.
Troubleshoot
Common codex-plugin-cc setup problems to check first.
A single troubleshooting section matters for SEO because many searches happen only after an install goes sideways. These are the checks most likely to unblock a local setup without turning this page into a long support transcript.
Common issue
Setup cannot find Codex
If /codex:setup reports that Codex is missing, install Codex locally or let setup prompt for it, then rerun the command after reload.
Common issue
Codex is installed but not authenticated
If the plugin finds Codex but setup still cannot proceed, authenticate the local Codex install first and then rerun setup.
Common issue
Project settings do not seem to apply
Verify that the repository is trusted and that .codex/config.toml exists at the project root, otherwise the plugin will fall back to user defaults.

FAQ
Common codex-plugin-cc questions from first-time users.
These questions are written to match the way developers usually search when they are trying to install Codex Plugin for Claude Code, understand the command set, or debug a setup that is not ready yet.
What is codex-plugin-cc?
codex-plugin-cc is the keyword and repo-style name many developers search for when they want the official Codex Plugin for Claude Code and the commands needed to install it locally.
How do I install Codex Plugin for Claude Code?
Add the marketplace source, install the codex plugin package, reload plugins, and run /codex:setup so the local Codex environment can be detected and verified.
How do I configure codex-plugin-cc after install?
Configure Codex itself, not a separate plugin-only settings file. Put user defaults in ~/.codex/config.toml and project-specific overrides in .codex/config.toml when the repository is trusted.
Which command should I run first after setup?
A practical first run is /codex:review --background followed by /codex:status and /codex:result so you can confirm the full review loop without blocking your current thread.
When should I use rescue instead of review?
Use review when you want inspection and feedback. Use rescue when you want Codex to take over the investigation or fix path directly.
What should I check if setup still fails?
Confirm that Codex is installed locally, confirm authentication is complete, reload plugins, and verify that any project-level .codex/config.toml file is placed in a trusted repository root.
