## Summary `just fmt` previously used `uv run --with ruff` to make Ruff available. Because `--with` creates an ephemeral overlay outside the project lockfile, uv periodically re-resolved Ruff (by default every 10 minutes) instead of using the version recorded in `uv.lock`. Move the Python SDK tooling dependencies from the published `dev` extra into `format`, `test`, and composed `dev` dependency groups. The formatter now selects only the locked `format` group, contributor and CI setup explicitly sync the `dev` group, and CI and release commands reuse that environment with `--frozen --no-sync`. The scripts formatter also uses its project's locked Ruff dependency instead of an ephemeral overlay. Validated the Python 3.12 SDK suite (119 passed, 38 skipped) and the repository formatter.
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.
Examples use plain strings for text-only turns and typed input objects for multimodal or structured input lists.
Prerequisites
- Python
>=3.10 - Install the SDK for the same Python interpreter you will use to run examples
Install the published beta:
python -m pip install openai-codex
The SDK installs its pinned openai-codex-cli-bin runtime dependency.
The pinned runtime version comes from the SDK package dependency.
Run From A Checkout
Contributors using these checked-in scripts should install development
dependencies from sdk/python:
uv sync --group dev
source .venv/bin/activate
The examples bootstrap local SDK imports from sdk/python/src. If the pinned
runtime is not already installed, the bootstrap installs the matching runtime
package for the active interpreter and cleans up temporary files afterward.
Run examples
From sdk/python:
python examples/<example-folder>/sync.py
python examples/<example-folder>/async.py
The checked-in examples use the local SDK source tree automatically.
