"""Local client for the advanced agent — POSTs to the ``/responses`` endpoint
exposed by ``server/advanced_app.py`` using the standard ``openai`` SDK.

The advanced server's ``responses_hook`` keys per-user history off the
OpenAI ``safety_identifier`` field, so we pass ``safety_identifier=`` here.

Pass ``--previous-response-id <id>`` to resume an existing AgentSession by
its isolation key. Because the server uses ``previous_response_id`` directly
as the ``AgentSession`` id, you can resume any session written by any
channel — for example a Telegram chat at
``--previous-response-id telegram:8741188429``.

Start the server first (in another shell)::

    cd server && uv run python advanced_app.py

Then::

    python call_server.py "What is the weather in Tokyo?"
    python call_server.py --previous-response-id telegram:8741188429 "What did we discuss?"
