Fix tool calling params

[0xrushi]

the params don't match test task message

test_message = {
        "content": {
            "type": "function_call",
            "name": "calculate",
            "parameters": [
                {"name": "operation", "value": "add"},
                {"name": "a", "value": 5},
                {"name": "b", "value": 3}
            ]
        },
        "role": "user"
    }
