yansenzhou-oai 26ad281fd1 Remove detached delivery from review/start (#57667)
## What changed

`review/start` now supports only inline reviews on the supplied thread and returns that thread's id as `reviewThreadId`. Clients can omit `delivery`, send `null`, or specify `"inline"`; `"detached"` is no longer supported.

For a separate review thread, call `thread/start` followed by `review/start`. To preserve conversation history with custom review instructions, use `thread/fork` followed by `turn/start`.

Remove detached review execution and its app-server dependency on `codex-agent-extension`, and update the protocol schemas and generated clients. Preserve `ReviewDelivery.inline` as a Python enum member.

## Testing

Add a Python regression test verifying that inline review delivery parses as `ReviewDelivery.inline` and round-trips to the original JSON.

OpenAI Codex Python SDK

Build Python applications that start Codex threads, run turns, stream progress, and control workspace access.

Install

Install the SDK:

pip install openai-codex

Quickstart

The SDK reuses your existing Codex authentication when one is already available:

from openai_codex import Codex

with Codex() as codex:
    thread = codex.thread_start()
    result = thread.run("Explain this repository in three bullets.")
    print(result.final_response)

thread.run(...) returns a TurnResult containing the final response, collected items, and token usage.

Authentication

Existing Codex authentication is reused automatically. To start ChatGPT browser login explicitly:

from openai_codex import Codex

with Codex() as codex:
    login = codex.login_chatgpt()
    print(login.auth_url)
    print(login.wait().success)

For device-code login:

with Codex() as codex:
    login = codex.login_chatgpt_device_code()
    print(login.verification_url, login.user_code)
    login.wait()

For API-key login:

with Codex() as codex:
    codex.login_api_key("sk-...")

Built-In Help

Use Python's standard help(openai_codex), help(Codex), or python -m pydoc openai_codex documentation tools.
