Error when adding tools to useEdgeRuntime

[igo]

Hi, I am trying to define tools on frontend. Tools doesn't have to do anything and I am not expecting any result from execution, it's solely for observing how the AI would behave. The problem is that when I try to define tools on frontend I get Unhandled Runtime Error: You tried to define a tool with the name findWeather, but it already exists. What is the proper way of defining tools in useEdgeRuntime?

const runtime = useEdgeRuntime({
  api: '/chat',
});
runtime.registerModelConfigProvider({
  getModelConfig: () => ({
    tools: {
      findWeather: {
        description: 'Find a weather',
        parameters: {
          type: 'object',
          properties: {
            location: {
              type: 'string',
              description: 'Location for weather info',
            },
          },
        },
        execute(args, context) {
          console.info({ args, context }, 'Executing findWeather tool');
          return `\`\`\`json\n${JSON.stringify(args, null, 2)}\n\`\`\``;
        },
      }
    }
  })
});


<Thread runtime={runtime} />

When I define tools only on backend they work and I can show tools UI on frontend.
