## Why The package-builder stack now creates a canonical Codex package directory where the entrypoint lives under `bin/`, bundled helper resources live under `codex-resources/`, and bundled PATH-style tools live under `codex-path/`. That layout is not specific to the standalone installer: npm, brew, install scripts, and manually unpacked artifacts should all be able to use the same package shape. The Rust runtime still only knew about the legacy standalone release layout, where resources sit next to the executable. A packaged binary therefore would not identify its package root or prefer the bundled `rg` from `codex-path/`. ## What changed - Adds `CodexPackageLayout` to `codex-install-context` and detects it from an executable path shaped like `<package>/bin/<entrypoint>` when `<package>/codex-package.json` is present. - Splits `InstallContext` into an install `method` plus an optional package layout so the layout is shared across npm, bun, brew, standalone, and other launch contexts. - Stores package-layout paths as `AbsolutePathBuf` values. - Keeps `codex-resources/` and `codex-path/` optional so Codex can still run with degraded behavior if sidecar directories are missing. - Updates `InstallContext::rg_command()` to prefer bundled `codex-path/rg` or `rg.exe`, then fall back to the legacy standalone resources location, then system `rg`. - Updates `codex doctor` reporting so package installs show package, bin, resources, and path directories, and so bundled search detection recognizes `codex-path/` for any install method. ## Test plan - `cargo test -p codex-install-context` - `cargo test -p codex-cli` - `cargo test -p codex-tui update_action::tests::maps_install_context_to_update_action` - `just bazel-lock-check`
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.
