## Why The root formatting entrypoints could drift: `just fmt` did not format the Justfile itself, and the CI-facing check recipe only checked Python scripts instead of matching everything formatted by `just fmt`. ## What changed - Add a shared cross-platform Python formatter driver used by both `just fmt` and `just fmt-check`. - Run Justfile, Rust, Python SDK, and internal-script formatter groups concurrently while buffering each formatter group's output until it finishes. - Log formatter starts immediately, then print each formatter group's labeled output when it completes. - Keep the SDK lint-fix and Ruff formatting passes ordered, with source comments explaining their distinct roles and the check-mode equivalents. - Run Ruff through shared `uv run --no-sync --with ruff` overlays so formatting works on clean glibc Linux checkouts without installing the platform-specific SDK runtime wheel. - Show `fmt-check` help text in `just -l` and simplify CI to call the shared driver through `just fmt-check`. - Pin the general CI workflow to `just@1.51.0` so its formatter agrees with the checked-in Justfile. - Add regression coverage for the thin Just recipes and the driver's formatter graph. ## Validation - `just fmt` - `just fmt-check` - `python3 -m pytest sdk/python/tests/test_artifact_workflow_and_binaries.py -k 'root_fmt or root_format' -q` - `pnpm run format` - `git diff --check` - `just -l | rg -n '^ fmt|fmt-check'` - `uvx --from uv==0.7.22 uv run --frozen --project sdk/python --no-sync --with ruff ruff check --diff sdk/python`
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
