"""Agent Framework agent client for the local_responses sample.

Creates a local :class:`agent_framework.Agent` backed by
:class:`agent_framework.openai.OpenAIChatClient` and points that client at the
hosted ``/responses`` endpoint for all turns:

1. ``What is the weather in Tokyo?``
2. ``And what about Amsterdam?``
3. ``Which of the two cities we just discussed is warmer?``

All turns use the same :class:`agent_framework.AgentSession`; the first turn
binds the hosted response id to the session, and later turns continue through
that session via a chain of rotating ``previous_response_id`` values. The
third turn only makes sense if the server still remembers the first turn, so
it also exercises session continuity across that whole chain, not just a
single hop.

Start the server first (in another shell)::

    uv run python app.py

Then::

    uv run python call_server_af.py
