# <-- Another Example -->
# assistant = Agent(
#     name="assistant",
#     instructions='You are a helpful assistant.',
#     model_settings=ModelSettings(
#         parallel_tool_calls=True,
#     ),
#     tool_use_behavior='stop_on_first_tool',
#     tools=[say_hello, say_bye]
# )
# result = Runner.run_sync(
#     assistant, input='say bye first then hello', run_config=config
# )

# Question: Why the result of say_bye will be the final_output?
