## Why The package layout gives Codex a stable place for runtime helpers that should travel with the entrypoint. `shell_zsh_fork` still required users to configure `zsh_path` manually, even though we already publish prebuilt zsh fork artifacts. This PR builds on #24129 and uses the shared DotSlash artifact fetcher to include the zsh fork in Codex packages when a matching target artifact exists. Packaged Codex builds can then discover the bundled fork automatically; the user/profile `zsh_path` override is removed so the feature uses the package-managed artifact instead of a legacy path knob. ## What Changed - Added `scripts/codex_package/codex-zsh`, a checked-in DotSlash manifest for the current macOS arm64 and Linux zsh fork artifacts. - Taught `scripts/build_codex_package.py` to fetch the matching zsh fork artifact and install it at `codex-resources/zsh/bin/zsh` when available for the selected target. - Added package layout validation for the optional bundled zsh resource. - Added `InstallContext::bundled_zsh_path()` and `InstallContext::bundled_zsh_bin_dir()` for package-layout resource discovery. - Threaded the packaged zsh path through config loading as the runtime `zsh_path` for packaged installs, and removed the config/profile/CLI override path. - Kept the packaged default zsh override typed as `AbsolutePathBuf` until the existing runtime `Config::zsh_path` boundary. - Updated app-server zsh-fork integration tests to spawn `codex-app-server` from a temporary package layout with `codex-resources/zsh/bin/zsh`, matching the new packaged discovery path instead of setting `zsh_path` in config. - Switched package executable copying from metadata-preserving `copy2()` to `copyfile()` plus explicit executable bits, which avoids macOS file-flag failures when local smoke tests use system binaries as inputs. ## Testing To verify that the `zsh` executable from the Codex package is picked up correctly, first I ran: ```shell ./scripts/build_codex_package.py ``` which created: ``` /private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/ ``` so then I ran: ``` /private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/bin/codex exec --enable shell_zsh_fork 'run `echo $0`' ``` which reported the following, as expected: ``` /private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/codex-resources/zsh/bin/zsh ``` --- [//]: # (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
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.
