## Why Keep Python protocol models aligned with the checked-in app-server schemas and preserve reviewed generated artifacts when staging SDK releases. ## What changed - Generate SDK types from the schema directory configured in `pyproject.toml`, with a `--schema-dir` override, instead of invoking the pinned runtime binary. - Refresh Python artifacts through `just write-app-server-schema` for standard repository exports. Skip SDK updates for scratch and experimental exports. - Regenerate protocol models and notification dispatch, deriving the known payload union from the registry so `Notification.payload` covers every registered event. - Explicitly allowlist convenience API parameters so new protocol fields do not silently expand method signatures. Preserve existing approval path wrappers. - Stage SDK releases using checked-in generated files without regenerating them. ## Testing Add coverage for schema selection, refresh gating and failure handling, release artifact preservation, notification payload typing, and approval path compatibility. Update the generation drift test to use repository schemas. GitOrigin-RevId: fab350b07cf170258b91fbafa8da384aeb2e3bd7
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-...")
