## Summary - Remove maintainer and release-process wording from the Python SDK README and docs. - Rewrite SDK-facing comments/docstrings so they read as standalone product documentation. - Add a real app-server integration smoke that follows the public quickstart-style `Codex() -> thread_start() -> run()` path. ## Integration coverage - Add `test_real_quickstart_style_flow_smoke` in the real app-server integration suite. ## Validation - Local tests were not run per repo guidance. CI should validate this branch once the PR is online.

# OpenAI Codex Python SDK (Experimental)
|
||
|
||
Experimental Python SDK for `codex app-server` JSON-RPC v2 over stdio, with a small default surface optimized for real scripts and apps.
|
||
|
||
The generated wire-model layer is sourced from the pinned `openai-codex-cli-bin`
|
||
runtime package and exposed as Pydantic models with snake_case Python fields
|
||
that serialize back to the app-server’s camelCase wire format.
|
||
The package root exports the ergonomic client API; public app-server value and
|
||
event types live in `openai_codex.types`.
|
||
|
||
## Install
|
||
|
||
```bash
|
||
cd sdk/python
|
||
uv sync
|
||
source .venv/bin/activate
|
||
```
|
||
|
||
Published SDK builds pin an exact `openai-codex-cli-bin` runtime dependency
|
||
with the same version as the SDK. Pass `AppServerConfig(codex_bin=...)` only
|
||
when you intentionally want to run against a specific local app-server binary.
|
||
|
||
## Quickstart
|
||
|
||
```python
|
||
from openai_codex import Codex
|
||
|
||
with Codex() as codex:
|
||
thread = codex.thread_start(model="gpt-5")
|
||
result = thread.run("Say hello in one sentence.")
|
||
print(result.final_response)
|
||
print(len(result.items))
|
||
```
|
||
|
||
`result.final_response` is `None` when the turn completes without a final-answer
|
||
or phase-less assistant message item.
|
||
|
||
## Docs map
|
||
|
||
- Golden path tutorial: `docs/getting-started.md`
|
||
- API reference (signatures + behavior): `docs/api-reference.md`
|
||
- Common decisions and pitfalls: `docs/faq.md`
|
||
- Runnable examples index: `examples/README.md`
|
||
- Jupyter walkthrough notebook: `notebooks/sdk_walkthrough.ipynb`
|
||
|
||
## Examples
|
||
|
||
Start here:
|
||
|
||
```bash
|
||
cd sdk/python
|
||
python examples/01_quickstart_constructor/sync.py
|
||
python examples/01_quickstart_constructor/async.py
|
||
```
|
||
|
||
## Runtime
|
||
|
||
Published SDK builds are pinned to an exact `openai-codex-cli-bin` package
|
||
version, and that runtime package carries the platform-specific binary for the
|
||
target wheel. The SDK package version and runtime package version must match.
|
||
|
||
## Compatibility and versioning
|
||
|
||
- Package: `openai-codex`
|
||
- Runtime package: `openai-codex-cli-bin`
|
||
- Python: `>=3.10`
|
||
- Target protocol: Codex `app-server` JSON-RPC v2
|
||
- Versioning rule: the SDK package version is the underlying Codex runtime version
|
||
|
||
## Notes
|
||
|
||
- `Codex()` is eager and performs startup + `initialize` in the constructor.
|
||
- Use context managers (`with Codex() as codex:`) to ensure shutdown.
|
||
- Prefer `thread.run("...")` for the common case. Use `thread.turn(...)` when
|
||
you need streaming, steering, or interrupt control.
|
||
- For transient overload, use `retry_on_overload` from the package root.
