## Why Release packaging should be a staging step once release binaries have already been built and signed. The Windows release job was downloading and signing `codex-command-runner.exe` and `codex-windows-sandbox-setup.exe`, but `scripts/build_codex_package.py` still rebuilt those helpers while creating the package archives. That makes the package step slower and, more importantly, risks putting helper binaries in the archive that were produced after the signing step. Linux had the same shape for package resources: `bwrap` could be rebuilt by the package builder instead of being passed in as a prebuilt release artifact. This builds on #23752, which fixes `.tar.zst` creation when Windows runners rely on the repository DotSlash `zstd` wrapper. ## What changed - Add explicit prebuilt resource inputs to the Codex package builder: - `--bwrap-bin` - `--codex-command-runner-bin` - `--codex-windows-sandbox-setup-bin` - Make `.github/scripts/build-codex-package-archive.sh` pass resource binaries from the release output directory when they are already present. - Build Linux `bwrap` for app-server release jobs too, so app-server package creation does not invoke Cargo just to supply the package resource. - Keep macOS package creation as a no-Cargo path when `--entrypoint-bin` is provided, since macOS packages have no resource binaries. - Add unit coverage showing prebuilt macOS, Linux, and Windows package inputs result in no source-built binaries. ## Verification - `python3 -m unittest discover -s scripts/codex_package -p 'test_*.py'` - `python3 -m py_compile scripts/codex_package/*.py` - `bash -n .github/scripts/build-codex-package-archive.sh` - Dry-ran Linux and Windows package builds with fake prebuilt resources and a nonexistent Cargo path to verify the package builder did not invoke Cargo. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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.
