Codex Plugin for Claude Code
OpenAI
Codex Plugin for Claude Code lets you invoke OpenAI Codex from inside Claude Code for reviews, adversarial checks, and delegated background tasks.
Key features
- Codex Code Review Slash Commands: /codex:review runs a normal Codex read-only review of uncommitted changes or a branch against a base ref like main.
- Adversarial Review: /codex:adversarial-review runs a steerable review that questions the design and pressure-tests assumptions, tradeoffs, and failure modes.
- Delegated Rescue Tasks: /codex:rescue hands off tasks to a codex-rescue subagent so Codex can investigate bugs, try fixes, or continue previous Codex threads.
- Session Hand-Off: /codex:transfer moves the current Claude Code session over to Codex for continued work, keeping context intact.
- Background Job Management: /codex:status, /codex:result, and /codex:cancel manage long-running Codex jobs kicked off in the background.
- Zero-Setup Onboarding: /codex:setup detects whether Codex is installed and logged in and can offer to install it via npm if missing.
Best for
- Second-Opinion Code Review: Ask Codex to review the same uncommitted changes Claude Code just produced before shipping.
- Adversarial Design Review: Pressure test a chosen implementation for auth, data-loss, rollback, race-condition, or reliability risks before merge.
- Delegating Bug Investigations: Hand off a bug investigation to Codex in the background while continuing other work in Claude Code.
- Multi-Agent Coding Workflow: Route different types of tasks (fixes, refactors, reviews) to whichever agent is best suited without leaving Claude Code.
- Branch Reviews Before Merge: Run /codex:review base main to get a Codex review of the entire feature branch as part of your PR process.

PlugThis
AI Chrome extension builder — describe what you want in plain English and get a working Manifest V3 extension with real backend in under two minutes.

- Iterative Chat Refinement: Unlimited chats per extension to build, debug and polish before shipping.
- Chrome Web Store Ready: Output includes assets and Manifest V3 configuration required for Web Store submission.
- Idea Templates: Starter templates (Pomodoro, page highlighter, dark mode, CSS inspector, exercise reminder) for quick jump-starts.
Best for
- SaaS Extension Companions: Founders ship a Chrome extension that extends their product without a dedicated engineering team.
- Internal Team Tools: Build a company-specific extension for research, HR onboarding or CRM shortcuts in a single afternoon.

- AI Feature Prototypes: Wire a Chrome extension to OpenAI/Anthropic/Gemini keys to prototype an AI writing, translation or reply tool.
