New config key: [network_proxy.policy].allow_unix_sockets (string array), stored/edited via network_proxy.rs.
Entries support:
SSH_AUTH_SOCK / ${SSH_AUTH_SOCK}
preset aliases: ssh-agent, ssh_auth_sock, ssh_auth_socket
Entries are resolved at runtime to canonical absolute socket paths before generating Seatbelt rules.
macOS Seatbelt integration
seatbelt.rs now:
allows only loopback proxy ports (localhost:<port>) + explicitly allowed unix socket paths
does not emit per-domain (remote tcp ...) rules (those break under sandbox-exec)
Unix socket allowlist resolution is done via network_proxy::resolve_unix_socket_allowlist(...).
Prompt-on-deny UX (TUI)
When an exec approval happens and the command appears to need the SSH agent socket (ssh/scp/sftp/ssh-add, or git with ssh-style remotes), and the socket isn’t already allowed:
TUI shows an approval modal for the unix socket.
Allow for session: writes the resolved socket path to config (and removes it on exit, like session domain approvals).
Allow always: writes SSH_AUTH_SOCK to allow_unix_sockets for portability across restarts.
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 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. If you use npm:
npm install -g @openai/codex
Alternatively, if you use Homebrew:
brew install --cask codex
Then simply run codex to get started:
codex
If you're running into upgrade issues with Homebrew, see the FAQ entry on brew upgrade codex.
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
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Team, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup. If you previously used an API key for usage-based billing, see the migration steps. If you're having trouble with login, please comment on this issue.
Model Context Protocol (MCP)
Codex can access MCP servers. To configure them, refer to the config docs.
