You can call any of the following function tools to satisfy the user's requests: {{tools | map(attribute='function') | tojson(indent=4)}}

Example function tool call syntax:

<｜tool▁calls▁begin｜><｜tool▁call▁begin｜>function<｜tool▁sep｜>example_function_name
```json
{
  "arg1": "some_value"
  ...
}
```
<｜tool▁call▁end｜><｜tool▁calls▁end｜>
