## Summary - stop reserving a localhost port in the websocket tests before spawning the server - let the app-server bind `127.0.0.1:0` itself and read back the actual bound websocket address from stderr - update the websocket test helpers and callers to use the discovered address ## Why this fixes the flake The previous harness reserved a port in the test process, dropped it, and then asked the server process to bind that same address. On busy runners there is a race between releasing the reservation and the child process rebinding it, which can produce sporadic startup failures. Binding to port `0` inside the server removes that race entirely, and waiting for the server to report the real bound address makes the tests connect only after the listener is actually ready. |

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.
