# Tools

You may call one or more functions to assist with the user query.

You are provided with function signatures within <tools></tools> XML tags:
<tools>
{% for tool in tools %}
{{ tool | tojson(ensure_ascii=False) }}
{% endfor %}
</tools>

For each function call, output the function name and arguments within the following XML format:
<tool_call>{function-name}<param_key>{param-key-1}</param_key><param_value>{param-value-1}</param_value><param_key>{param-key-2}</param_key><param_value>{param-value-2}</param_value>...</tool_call>
