## Why Now that workspace crate features have been removed and `.github/scripts/verify_cargo_workspace_manifests.py` hard-bans new ones, Rust CI should stop building and testing with `--all-features`. Keeping `--all-features` in CI no longer buys us meaningful coverage for `codex-rs`, but it still makes the workflow look like we rely on Cargo feature permutations that we are explicitly trying to eliminate. It also leaves stale examples in the repo that suggest `--all-features` is a normal or recommended way to run the workspace. ## What changed - removed `--all-features` from the Rust CI `cargo chef cook`, `cargo clippy`, and `cargo nextest` invocations in `.github/workflows/rust-ci-full.yml` - updated the `just test` guidance in `justfile` to reflect that workspace crate features are banned and there should be no need to add `--all-features` - updated the multiline command example and snapshot in `codex-rs/tui/src/history_cell.rs` to stop rendering `cargo test --all-features --quiet` - tightened the verifier docstring in `.github/scripts/verify_cargo_workspace_manifests.py` so it no longer talks about temporary remaining exceptions ## How tested - `python3 .github/scripts/verify_cargo_workspace_manifests.py` - `cargo test -p codex-tui`
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.
