## Summary - support legacy `ReadOnlyAccess::Restricted` on Windows in the elevated setup/runner backend - keep the unelevated restricted-token backend on the legacy full-read model only, and fail closed for restricted read-only policies there - keep the legacy full-read Windows path unchanged while deriving narrower read roots only for elevated restricted-read policies - honor `include_platform_defaults` by adding backend-managed Windows system roots only when requested, while always keeping helper roots and the command `cwd` readable - preserve `workspace-write` semantics by keeping writable roots readable when restricted read access is in use in the elevated backend - document the current Windows boundary: legacy `SandboxPolicy` is supported on both backends, while richer split-only carveouts still fail closed instead of running with weaker enforcement ## Testing - `cargo test -p codex-windows-sandbox` - `cargo check -p codex-windows-sandbox --tests --target x86_64-pc-windows-msvc` - `cargo clippy -p codex-windows-sandbox --tests --target x86_64-pc-windows-msvc -- -D warnings` - `cargo test -p codex-core windows_restricted_token_` ## Notes - local `cargo test -p codex-windows-sandbox` on macOS only exercises the non-Windows stubs; the Windows-targeted compile and clippy runs provide the local signal, and GitHub Windows CI exercises the runtime path |

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.
Using Codex with your ChatGPT plan
