### Wire CopilotKit middleware into your graph

Agent config flows from the UI into the agent via `useAgentContext` — the
frontend publishes a typed object and `CopilotKitMiddleware` injects it
into the model's prompt on every turn. Make sure the middleware is in
your `create_agent` call.

<DemoCode file="src/agents/agent_config_agent.py" region="agent-config-setup" />

Read the resulting config inside your system prompt or a custom
middleware — see `src/agents/agent_config_agent.py` for the full
rulebook-driven shape used in the showcase.
