The test was flaky because it was checking the right thing in a roundabout way. What it wanted to prove: - plugin hooks receive the right environment variables. What it actually did: 1. Run a plugin hook. 2. Have that hook write those env vars into a temporary `env.json` file. 3. After the hook finished, read `env.json` back from disk. On Windows, that last file was sometimes not there when the test tried to read it, so the test failed with `read env log: file not found`. The hook system itself was not what the test failure was directly proving; the test was failing on the extra filesystem side effect it introduced. The fix is to stop using a temp file as the proof mechanism. The hook now prints the env values in its normal structured output, and the test asserts on the output that the hook engine already captures. So we still verify the same behavior, but without depending on a separate file being created and read back correctly on Windows.
npm i -g @openai/codex

Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
