Interactive components

"""The agent behind gen-ui-interrupt and interrupt-headless.``schedule_meeting`` is marked ``needs_approval``, so the SDK pauses the runbefore the tool executes and the adapter ends the AG-UI run with an interruptfor the call, its arguments on ``metadata.tool_input``. The page renders thetime picker from them and resolves the interrupt with ``{"approved": true,"chosen_time": ..., "chosen_label": ...}``, or ``{"approved": false}`` whenthe user cancels. The next request carries that answer as a ``resume`` entry,and the adapter runs an approved call before the model sees the conversationagain.Nothing is kept on the server between the two runs: the paused call lives inthe conversation the page holds."""from collections.abc import AsyncIteratorfrom contextlib import aclosingfrom contextvars import ContextVarfrom typing import Anyfrom ag_ui.core import BaseEvent, RunAgentInputfrom ag_ui_openai_agents import OpenAIAgentsAgentfrom agents import Agent, function_toolfrom agents.tool_context import ToolContextfrom demo_agents._common import MODEL, chat_settingsSYSTEM_PROMPT = """You are a scheduling assistant.Whenever the user asks you to book a call or schedule a meeting, you MUST callthe `schedule_meeting` tool.
