## Summary - require windowsSandbox/setupStart.cwd to be an AbsolutePathBuf - reject relative cwd values at request parsing instead of normalizing them later in the setup flow - add RPC-layer coverage for relative cwd rejection and update the checked-in protocol schemas/docs ## Why windowsSandbox/setupStart was carrying the client-provided cwd as a raw PathBuf for command_cwd while config derivation normalized the same value into an absolute policy_cwd. That left room for relative-path ambiguity in the setup path, especially for inputs like cwd: "repo". Making the RPC accept only absolute paths removes that split entirely: the handler now receives one already-validated absolute path and uses it for both config derivation and setup. This keeps the trust model unchanged. Trusted clients could already choose the session cwd; this change is only about making the setup RPC reject relative paths so command_cwd and policy_cwd cannot diverge. ## Testing - cargo test -p codex-app-server windows_sandbox_setup (run locally by user) - cargo test -p codex-app-server-protocol windows_sandbox (run locally by user)
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.
