## 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.

Python SDK Examples
Each example folder contains runnable versions:
sync.py(public sync surface:Codex)async.py(public async surface:AsyncCodex)
All examples intentionally use only public SDK exports from openai_codex
and openai_codex.types.
Prerequisites
- Python
>=3.10 - Install SDK dependencies for the same Python interpreter you will use to run examples
Recommended setup (from sdk/python):
uv sync
source .venv/bin/activate
When running examples from this repo checkout, the SDK source uses the local
tree and does not bundle a runtime binary. The helper in examples/_bootstrap.py
uses the installed openai-codex-cli-bin runtime package.
If the pinned openai-codex-cli-bin runtime is not already installed, the bootstrap
will download the matching GitHub release artifact, stage a temporary local
openai-codex-cli-bin package, install it into your active interpreter, and clean up
the temporary files afterward.
The pinned runtime version comes from the SDK package dependency.
Run examples
From sdk/python:
python examples/<example-folder>/sync.py
python examples/<example-folder>/async.py
The examples bootstrap local imports from sdk/python/src automatically, so no
SDK wheel install is required. You only need the Python dependencies for your
active interpreter and an installed openai-codex-cli-bin runtime package (either
already present or automatically provisioned by the bootstrap).
