有时会定义很多工具，而定义Agent的时候只想使用与问题相关的工具，这是可以通过向量数据库来检索相关的工具，传递给Agent

# Define which tools the agent can use to answer user queries
search = SerpAPIWrapper()
search_tool = Tool(name = "Search",func=search.run,description="useful for when you need to answer questions about current events")
def fake_func(inp: str) -> str:return "foo"
fake_tools = [Tool(name=f"foo-{i}", func=fake_func, description=f"a silly function that you can use to get more information about the number {i}") for i in range(99)
]
