Adding Tools

//define the tool function. This is your own custom function and can perform any logic you want.
const getWeather = async (city: string) => {
  try {
    const weather = await fetch(
      `http://api.weatherapi.com/v1/current.json?key=${process.env.NEXT_PUBLIC_WEATHER_API_KEY}&q=${city}`,
    );
    return weather.json();
  } catch (error) {
    throw new Error(`Failed to fetch weather for ${city}`);
  }
};

// Create a TamboTool definition including your tool function
export const tools: TamboTool[] = [
  {
    name: "get_weather",
    description: "Fetch current weather information for a specified city",
    tool: getWeather,
    toolSchema: z
      .function()
      .args(z.string().describe("The city to fetch weather for"))
      .returns(
        z.object({
          location: z.object({
            name: z.string(),
          }),
        }),
      ),
  },
];

// Register your tools with Tambo
<TamboProvider tools={tools}>
  <App />
</TamboProvider>;
