## What changed - The duration-recording fixture sleep was reduced from a large artificial delay to `0.2s`, and the assertion floor was lowered to `0.1s`. - The shell tool fixtures now force `login = false` so they do not invoke login-shell startup paths. ## Why this fixes the flake - The old tests were paying for two kinds of noise that had nothing to do with the feature being validated: oversized sleep time and variable shell initialization cost. - Login shells can pick up runner-specific startup files and incur inconsistent startup latency. - The test only needs to prove that we record a nontrivial duration and preserve shell output. A shorter fixture delay plus a non-login shell keeps that coverage while removing runner-dependent wall-clock variance. ## Scope - Test-only change.
npm i -g @openai/codex
or brew install --cask 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.
