## What changed - run the two plan-mode app-server tests on a multi-thread Tokio runtime instead of the default single-thread test runtime - stop relying on wiremock teardown expectations for `/responses` and explicitly wait for the expected request count after the turn completes ## Why this fixes the flake - this failure was showing up on Windows ARM as a late wiremock panic saying the mock server saw zero `/responses` calls, but the real issue was that the test could stall around app-server startup and only fail during teardown - moving these tests to the same multi-thread runtime used by the other collaboration-mode app-server tests removes that startup scheduling race - asserting the `/responses` count directly makes the test deterministic: we now wait for the real POST instead of depending on a drop-time verification that can hide the underlying timing issue ## Scope - test-only change; no production logic changes
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.
