## Why Codex CLI packaging is currently split across npm staging, standalone installers, and release bundle creation, which makes it hard to define and validate a single valid package directory. This adds the first standalone package builder so later release paths can converge on the same canonical layout. ## What changed - Added `scripts/build_codex_package.py` as the stable executable wrapper around `scripts/codex_package`. - Added modules for CLI parsing, target metadata, grouped cargo builds, package layout validation, and archive writing. - The builder creates a package directory with `codex-package.json`, `bin/`, `codex-resources/`, and `codex-path`, and can serialize it as `.tar.gz`, `.tar.zst`, or `.zip`. - Source-built artifacts are built by one grouped `cargo build`: `codex` for all targets, `bwrap` for Linux, and the Windows sandbox helpers for Windows. `rg` remains an input because it is vendored from upstream rather than built from this repo. - Added `scripts/codex_package/README.md` to document the package layout, source-built artifacts, and cargo profile behavior. ## Verification - Ran wrapper/module syntax compilation. - Ran `scripts/build_codex_package.py --help` from `/private/tmp`. - Ran fake-cargo package/archive builds for macOS, Linux, and Windows target layouts, including an assertion that generated tar archives contain no duplicate member names. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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.
