## Why `spawn_command_under_seatbelt()` in `codex-rs/core/src/seatbelt.rs` had fallen out of production use and was only referenced by test-only wrappers. That left us with sandbox tests that could stay green even if the actual seatbelt exec path regressed, because production shell execution now flows through `SandboxManager::transform()` and `ExecRequest::from_sandbox_exec_request()` instead of that helper. Removing the dead helper also exposed one downstream `codex-exec` integration test that still imported it, which broke `just clippy`. ## What Changed - Removed `codex-rs/core/src/seatbelt.rs` and stopped exporting `codex_core::seatbelt`. - Removed the redundant `codex-rs/core/tests/suite/seatbelt.rs` coverage that only exercised the dead helper. - Kept the `openpty` regression check, but moved it into `codex-rs/core/tests/suite/exec.rs` so it now runs through `process_exec_tool_call()`. - Fixed the seatbelt denial test in `codex-rs/core/tests/suite/exec.rs` to use `/usr/bin/touch`, so it actually exercises the sandbox instead of a nonexistent path. - Updated `codex-rs/exec/tests/suite/sandbox.rs` on macOS to build the sandboxed command through `build_exec_request()` and spawn the transformed command, instead of importing the removed helper. - Left the lower-level seatbelt policy coverage in `codex-rs/sandboxing/src/seatbelt_tests.rs`, where the policy generator is still covered directly. ## Verification - `cargo test -p codex-core suite::exec::` - `cargo test -p codex-exec` - `cargo clippy -p codex-exec --tests -- -D warnings`
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.
