## Why The Python SDK needs the same tight formatter/lint loop as the rest of the repo: a safe Ruff autofix pass, Ruff formatting, editor save behavior, and CI checks that catch drift. Without that loop, SDK changes can land with formatting or import ordering that differs from what reviewers and CI expect. ## What - Add Ruff configuration to `sdk/python/pyproject.toml`, excluding generated protocol code and notebooks from the normal lint/format pass. - Update `just fmt` so it still formats Rust and also runs Python SDK Ruff autofix and formatting. - Add Python SDK CI steps for `ruff check` and `ruff format --check` before pytest. - Recommend the Ruff VS Code extension and enable Python format/fix/organize-on-save so Cmd+S uses the same tooling. - Apply the resulting Ruff formatting to SDK Python files, examples, and the checked-in generated `v2_all.py` output emitted by the pinned generator. - Add a guard test for the `just fmt` recipe so it keeps working from both Rust and Python SDK working directories. ## Stack 1. #21891 `[1/8]` Pin Python SDK runtime dependency 2. #21893 `[2/8]` Generate Python SDK types from pinned runtime 3. #21895 `[3/8]` Run Python SDK tests in CI 4. #21896 `[4/8]` Define Python SDK public API surface 5. #21905 `[5/8]` Rename Python SDK package to `openai-codex` 6. #21910 `[6/8]` Add high-level Python SDK approval mode 7. #22014 `[7/8]` Add Python SDK app-server integration harness 8. This PR `[8/8]` Add Python SDK Ruff formatting ## Verification - Added `test_root_fmt_recipe_formats_rust_and_python_sdk` for the shared format recipe. - Ran `just fmt` after the recipe update. --------- Co-authored-by: Codex <noreply@openai.com>
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.
