  properties: {
    location: {
      type: 'string',
      description: 'The city and state, e.g. San Francisco, CA'
    },
    unit: {
      type: 'string',
      enum: ["celsius", "fahrenheit"]
    }
  },
  required: ["location"]
};

tools.add(
  'get_current_weather',
  'Get the current weather in a given location',
  parameters,
  async (params) => {
    const res = {
      location: params.location,
      temperature: 24,
      unit: params.unit
    };
    return res;
  }
);

const weather = await tools.call('get_current_weather', { location: 'Den Haag' });
console.log(weather); // { location: 'Den Haag', temperature: 24, unit: undefined }
