Ahmed Ibrahim 4d0c4cd058 [codex] Add independent beta release for the Python SDK (#24828)
## Why

`openai-codex` needs a beta release lifecycle without requiring beta
releases of its pinned runtime package. Previously, SDK staging rewrote
its runtime dependency to the SDK version, which made an SDK-only beta
impossible.

## What changed

- Set the initial SDK beta version to `0.1.0b1` and pin it to published
stable `openai-codex-cli-bin==0.132.0`.
- Decoupled SDK release staging from runtime versioning so it preserves
the reviewed exact runtime pin.
- Added a `python-v*` tag workflow that builds and publishes only
`openai-codex` through PyPI trusted publishing.
- Removed the Beta classifier from runtime package metadata for future
runtime publications.
- Regenerated protocol-derived SDK models from the selected stable
runtime package.

`0.132.0` is the newest stable runtime admitted by the checked-in
dependency date fence and retains the Linux wheel family currently used
by SDK CI.

## Release setup

Before pushing `python-v0.1.0b1`, configure PyPI trusted publishing for
the `openai-codex` project with workflow `python-sdk-release.yml`,
environment `pypi`, and job `publish-python-sdk`.

## Validation

- `uv run --frozen --extra dev ruff check src/openai_codex scripts
examples tests`
- Parsed `.github/workflows/python-sdk-release.yml` with PyYAML.
- Built staged release artifacts locally:
`openai_codex-0.1.0b1-py3-none-any.whl` and
`openai_codex-0.1.0b1.tar.gz`.
- Verified wheel metadata pins `openai-codex-cli-bin==0.132.0`.
- Tests are deferred to online CI for this PR.

# 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 protocol's camelCase wire format.
The package root exports the ergonomic client API; public Codex protocol 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 compatible `openai-codex-cli-bin` runtime
dependency. Pass `CodexConfig(codex_bin=...)` only
when you intentionally want to run against a specific local app-server binary.
## Quickstart
```python
from openai_codex import Codex, Sandbox
with Codex() as codex:
# Call login_api_key(...) first when this Codex session is not
# already authenticated.
thread = codex.thread_start(model="gpt-5", sandbox=Sandbox.workspace_write)
result = thread.run("Say hello in one sentence.")
print(result.final_response)
print(len(result.items))
```
`thread.run(...)` and `thread.turn(...).run()` return `TurnResult`. Its
`final_response` is `None` when the turn completes without a final-answer or
phase-less assistant message item.
## Sandbox
Use the same enum when creating a thread or changing its sandbox for a turn:
```python
from openai_codex import Codex, Sandbox
with Codex() as codex:
thread = codex.thread_start(sandbox=Sandbox.workspace_write)
thread.run("Make the requested change.")
review = thread.run("Review the diff only.", sandbox=Sandbox.read_only)
```
Available presets:
- `Sandbox.read_only`: read files without allowing writes.
- `Sandbox.workspace_write`: the normal default for projects with a recorded trust decision; read files and write inside the workspace and configured writable roots.
- `Sandbox.full_access`: run without filesystem access restrictions.
When `sandbox=` is omitted, Codex uses its configured default. A sandbox
passed to `run(...)` or `turn(...)` applies to that turn and subsequent turns
on the thread.
## Login
Use the auth helper that matches your app:
```python
from openai_codex import Codex
with Codex() as codex:
codex.login_api_key("sk-...")
account = codex.account()
print(account.account)
```
Interactive ChatGPT login returns a handle. Open the provided URL or device-code
page, then wait for the matching completion event:
```python
with Codex() as codex:
login = codex.login_chatgpt()
print(login.auth_url)
completed = login.wait()
print(completed.success)
```
Use `login_chatgpt_device_code()` for device-code auth, `handle.cancel()` to
stop an in-progress interactive login, and `logout()` to clear the active
Codex account session.
## 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. SDK beta releases are versioned independently of runtime releases.
## 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: SDK releases pin one exact compatible Codex runtime version
## Notes
- `Codex()` is eager and performs startup + `initialize` in the constructor.
- Use context managers (`with Codex() as codex:`) to ensure shutdown.
- Plain strings are accepted anywhere a turn input is accepted; they are
shorthand for `TextInput(...)`.
- 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.
