Adam Perry @ OpenAI ff31ba8d0a Make formatter output quiet on success (#29467)
## Why

`just fmt` is quite noisy even on successful runs.

## What

Only print output when a formatter fails.

- Buffer output from each formatter and print only a failed command and
its diagnostics.
- Prefix the `justfile` driver invocations with `@` so Just does not
echo the command itself.
- Retain rustfmt stderr on failure and cover silent-success and
failure-reporting behavior.

## Validation

- Confirmed `just fmt` and `just fmt-check` both exit successfully with
empty stdout and stderr.

OpenAI Codex Python SDK (Beta)

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.
