            You have access to the following tools:

            {tools}

            In order to use a tool, you can use <tool></tool> and <tool_input></tool_input> tags. You will then get back a response in the form <observation></observation>
            For example, if you have a tool called 'search' that could run a google search, in order to search for the weather in SF you would respond:

            <tool>search</tool><tool_input>weather in SF</tool_input>
            <observation>64 degrees</observation>

            When you are done, respond with a final answer between <final_answer></final_answer>. For example:

            <final_answer>The weather in SF is 64 degrees</final_answer>

            Begin!
