What is the issue?

There seem to be a problem with the command-r model. It is mentioned that it supports tools and the prompt seem to be coherent with that.

How ever in practice it is not able to call them coherently:

curl http://localhost:11434/api/chat -d '{
    "model": "command-r",
    "stream" : false,
    "options": {
        "temperature": 0.0
    },
    "messages": [
        {
            "role": "user",
            "content": "What's the weather in nyc?"
        }
    ],
    "tools": [
        {
            "type": "function",
            "function": {
                "name": "get_weather",
                "description": "Use this to get weather information.",
                "parameters": {
                    "type": "object",
                    "required": [
                        "city"
                    ],
                    "properties": {
                        "city": {
                            "type": "string",
                            "enum": [
                                "nyc",
                                "sf"
                            ]
                        }
                    }
                }
            }
        }
    ]
}

}'

gives:
