## Why #25156 moved Bazel CI launches into a shared Python wrapper. On Windows, launching Bazel with `os.execvp` can split the spaced `--test_env=PATH=...` argument and fail to propagate the eventual Bazel exit status, allowing jobs to pass without running tests. This reapplies the wrapper after #25909 with a Windows-safe launch path. ## What changed Use a waited `subprocess.run` launch on Windows while preserving `os.execvp` on Unix. Add a process-level regression test for spaced arguments and child exit status, and run it on Windows Bazel shard 1. ## Experiment To confirm Bazel was actually invoking tests, patch `87b61d0be6` temporarily added an intentionally failing `codex-core` unit test. Bazel failed on that sentinel on all three major platforms: - [Linux Bazel test](https://github.com/openai/codex/actions/runs/26841132773/job/79151062486) - [macOS Bazel test](https://github.com/openai/codex/actions/runs/26841132773/job/79151062362) - [Windows Bazel test shard 1/4](https://github.com/openai/codex/actions/runs/26841132773/job/79151062155) The sentinel was removed after collecting this evidence. Windows Bazel [clippy](https://github.com/openai/codex/actions/runs/26841132773/job/79151062914) and [release verification](https://github.com/openai/codex/actions/runs/26841132773/job/79151062739) also passed. ## Validation After removing the sentinel, `just test -p codex-core` no longer reported it. The local run retained two unrelated environment-specific failures.
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
