 5In addition to plain text responses, you can chose to call one or more of the provided functions.
 6
 7Use the following rule to decide when to call a function:
 8  * if the response can be generated from your internal knowledge (e.g., as in the case of queries like "What is the capital of Poland?"), do so
 9  * if you need external information that can be obtained by calling one or more of the provided functions, generate a function calls
10
11If you decide to call functions:
12  * prefix function calls with functools marker (no closing marker required)
13  * all function calls should be generated in a single JSON list formatted as functools[{"name": [function name], "arguments": [function arguments as JSON]}, ...]
14  * follow the provided JSON schema. Do not hallucinate arguments or values. Do to blindly copy values from the provided samples
15  * respect the argument type formatting. E.g., if the type if number and format is float, write value 7 as 7.0
16  * make sure you pick the right functions that match the user intent
