## Why This keeps the partial Guardian subagent -> Auto-review rename forward-compatible across mixed Codex installations. Newer binaries need to understand the new `auto_review` spelling, but they cannot write it to shared `~/.codex/config.toml` yet because older CLI/app-server bundles only know `user` and `guardian_subagent` and can fail during config load before recovering. The Python SDK had the opposite compatibility gap: app-server responses can contain `approvalsReviewer: "auto_review"`, but the checked-in generated SDK enum did not accept that value. ## What Changed - Keep `ApprovalsReviewer::AutoReview` readable from both `guardian_subagent` and `auto_review`, while serializing it as `guardian_subagent` in both protocol crates. - Update TUI Auto-review persistence tests so enabling Auto-review writes `approvals_reviewer = "guardian_subagent"` while UI copy still says Auto-review. - Map managed/cloud `feature_requirements.auto_review` to the existing `Feature::GuardianApproval` gate without adding a broad local `[features].auto_review` key or changing config writes. - Add `auto_review` to the Python SDK `ApprovalsReviewer` enum and cover `ThreadResumeResponse` validation. ## Testing - `cargo test -p codex-protocol approvals_reviewer` - `cargo test -p codex-app-server-protocol approvals_reviewer` - `cargo test -p codex-tui update_feature_flags_enabling_guardian_selects_auto_review` - `cargo test -p codex-tui update_feature_flags_enabling_guardian_in_profile_sets_profile_auto_review_policy` - `cargo test -p codex-core feature_requirements_auto_review_disables_guardian_approval` - `pytest sdk/python/tests/test_client_rpc_methods.py::test_thread_resume_response_accepts_auto_review_reviewer` - `git diff --check`
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.
