## Why The package builder already fetches `rg` from a checked-in DotSlash manifest. The zsh packaging work needs the same fetch/cache/size-check/SHA-256/extract path for another manifest, but keeping that refactor inside the zsh PR makes the review harder to follow. This PR factors the existing `rg`-specific implementation into a reusable helper with no intended behavior change for `rg` packaging. ## What Changed - Added `scripts/codex_package/dotslash.py` for checked-in DotSlash manifest parsing, archive download, cache reuse, size validation, SHA-256 validation, and member extraction. - Updated `scripts/codex_package/ripgrep.py` to delegate to the shared helper. - Preserved the existing `rg` manifest path, cache key, destination filename, and executable-bit behavior. ## Testing - `python3 -m py_compile scripts/codex_package/dotslash.py scripts/codex_package/ripgrep.py scripts/codex_package/cli.py scripts/codex_package/layout.py scripts/codex_package/zsh.py` - `python3 -m unittest discover scripts/codex_package` --- [//]: # (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.
