A Claude Code plugin that delegates code review, adversarial design checks, and background tasks to Codex using the existing local Codex CLI. Operation requires an active ChatGPT subscription or OpenAI API key, and review-gate usage may consume API limits quickly.
Project overview
The plugin connects Claude Code to Codex for read-only reviews, session transfers, and task delegation without requiring a separate Codex runtime, relying on existing local Codex CLI configuration.

Best for
Developers using Claude Code who want to delegate tasks to Codex for read-only reviews or background investigations using their local Codex CLI configuration.
Users who need to continue a Claude Code session within Codex while preserving the session context.
Key capabilities
Provides a read-only code review of uncommitted changes or a specific branch by delegating to Codex.
Questions the chosen implementation and design to pressure-test assumptions, tradeoffs, and failure modes.
Delegates tasks to Codex to investigate bugs, try fixes, or take a faster pass with a smaller model.
Creates a persistent Codex thread from the current Claude Code session to continue the same context directly in Codex.
Shows running and recent Codex jobs, retrieves final stored output, and cancels active background jobs.
Uses a Stop hook to run a targeted Codex review based on Claude's response and blocks the stop if issues are found.
Checks whether Codex is installed and authenticated, and can offer to install Codex if missing.
Limitations and risks
Requires a ChatGPT subscription or OpenAI API key, and uses Codex models such as gpt-5.4-mini and gpt-5.3-codex-spark, meaning inference relies on remote services.
Session transfer source must be under ~/.claude/projects, and older Codex versions must be upgraded.
Enabling the review gate can create a long-running Claude/Codex loop and may drain usage limits quickly.
Getting started
Run the plugin marketplace add command, install the plugin, reload plugins, and execute the setup command in Claude Code.
Node.js 18.18 or later is required. The setup assistant checks if Codex is installed and authenticated, and can offer to install Codex via npm if it is missing.
Alternatives and comparisons
Provides an AI development environment that runs CLI coding agents in isolated parallel worktrees tracked from a single application.
