Codex Inside Claude Code

OpenAI's official plugin puts Codex inside Claude Code. Two commands, about 30 seconds, and the two strongest AI coding tools work in one terminal.
01
Install it30 seconds
Open Claude Code and run the two commands below. That's the whole setup. You need a ChatGPT subscription (free works) or an OpenAI API key.
02
Let them split the workSaves tokens
Claude plans the build and writes the spec. Codex writes the code. You direct both from one chat and burn fewer Claude tokens.
03
Review before you shipCatch bugs
Run /codex:review for a read-only code review, or /codex:adversarial-review to make the two AIs challenge each other, band for band, until the best solution wins.

TIP 01
Start every feature with Claude planning and Codex building. One plans, one types.
TIP 02
Run /codex:review before every ship. It catches race conditions and missing error states.
TIP 03
Use /codex:rescue to hand a stuck session to Codex and keep moving.
