## Why Config loading had become split across crates: `codex-config` owned the config types and merge logic, while `codex-core` still owned the loader that assembled the layer stack. This change consolidates that responsibility in `codex-config`, so the crate that defines config behavior also owns how configs are discovered and loaded. To make that move possible without reintroducing the old dependency cycle, the shell-environment policy types and helpers that `codex-exec-server` needs now live in `codex-protocol` instead of flowing through `codex-config`. This also makes the migrated loader tests more deterministic on machines that already have managed or system Codex config installed by letting tests override the system config and requirements paths instead of reading the host's `/etc/codex`. ## What Changed - moved the config loader implementation from `codex-core` into `codex-config::loader` and deleted the old `core::config_loader` module instead of leaving a compatibility shim - moved shell-environment policy types and helpers into `codex-protocol`, then updated `codex-exec-server` and other downstream crates to import them from their new home - updated downstream callers to use loader/config APIs from `codex-config` - added test-only loader overrides for system config and requirements paths so loader-focused tests do not depend on host-managed config state - cleaned up now-unused dependency entries and platform-specific cfgs that were surfaced by post-push CI ## Testing - `cargo test -p codex-config` - `cargo test -p codex-core config_loader_tests::` - `cargo test -p codex-protocol -p codex-exec-server -p codex-cloud-requirements -p codex-rmcp-client --lib` - `cargo test --lib -p codex-app-server-client -p codex-exec` - `cargo test --no-run --lib -p codex-app-server` - `cargo test -p codex-linux-sandbox --lib` - `cargo shear` - `just bazel-lock-check` ## Notes - I did not chase unrelated full-suite failures outside the migrated loader surface. - `cargo test -p codex-core --lib` still hits unrelated proxy-sensitive failures on this machine, and Windows CI still shows unrelated long-running/timeouting test noise outside the loader migration itself.
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.
