## Why `approvals_reviewer` now uses `auto_review` as the canonical config/API value after #18504, but the Rust enum variant and nearby helper/test names still used `GuardianSubagent` / guardian approval wording. That made follow-up code and reviews confusing even though the external value had already moved to Auto-review. ## What changed - Renamed `ApprovalsReviewer::GuardianSubagent` to `ApprovalsReviewer::AutoReview`. - Updated protocol, app-server, config, core, TUI, exec, and analytics test callsites. - Renamed nearby helper/test names from guardian approval wording to Auto-review wording where they refer to the approvals reviewer mode. - Preserved wire compatibility: - `auto_review` remains the canonical serialized value. - `guardian_subagent` remains accepted as a legacy alias. This intentionally does not rename the `[features].guardian_approval` key, `Feature::GuardianApproval`, `core/src/guardian`, analytics event names, or app-server Guardian review event types. ## Verification - `cargo test -p codex-protocol approvals_reviewer_serializes_auto_review_and_accepts_legacy_guardian_subagent` - `cargo test -p codex-app-server-protocol approvals_reviewer_serializes_auto_review_and_accepts_legacy_guardian_subagent` - `cargo test -p codex-config approvals_reviewer` - `cargo test -p codex-tui update_feature_flags` - `cargo test -p codex-core permissions_instructions` - `cargo test -p codex-tui permissions_selection`
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.
