## Why The `codex-windows-sandbox` crate was embedding Windows resource metadata through a package-level `build.rs`. Because that package also exposes the `codex_windows_sandbox` library, downstream binaries that link the library could inherit `FileDescription` / `ProductName` values of `codex-windows-sandbox`. That made ordinary Codex binaries, including the long-lived `codex.exe` app-server sidecar, appear as `codex-windows-sandbox` in Windows UI surfaces such as Task Manager / file properties. We do not rely on this metadata enough to justify a larger bin-only resource split, so this removes the resource stamping entirely. ## What changed - Removed the `windows-sandbox-rs` build script that invoked `winres`. - Removed the setup manifest that was only consumed by that build script. - Removed the `winres` build dependency and corresponding `Cargo.lock` / `MODULE.bazel.lock` entries. - Removed the now-unused Bazel build-script data. ## Verification - `cargo build -p codex-windows-sandbox --bins` - `cargo build -p codex-cli --bin codex` - `bazel mod deps --lockfile_mode=update` via Bazelisk, with local remote-cache-disabling flags because `bazel` is not installed on PATH here - `bazel mod deps --lockfile_mode=error` via Bazelisk, with the same local flags - Verified rebuilt `codex.exe`, `codex-command-runner.exe`, and `codex-windows-sandbox-setup.exe` now have blank `FileDescription` / `ProductName` fields. - `cargo test -p codex-windows-sandbox` still fails on two legacy Windows sandbox tests with `CreateRestrictedToken failed: 87` and the follow-on poisoned test lock; 85 passed, 2 ignored.
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.
