I'm trying to understand why only 2 out of the 3 registered tools are being called.

      const result = streamText({
        model: google("gemini-2.5-flash"),
        messages: convertToModelMessages(messages),
        tools: {
          get_weather: getWeather,
          google_search: google.tools.googleSearch({
            mode: "MODE_DYNAMIC",
            dynamicThreshold: 0.7,
          }),
          url_context: google.tools.urlContext({}),
        },
        toolChoice: "auto",
      });

I'm using ai-sdk@5, and currently, only the google_search and url_context tools are being invoked but get_weather isn't being called. I don’t believe there’s an issue with my code, but I can’t figure out why only the built-in Gemini tools are working while the custom one isn’t.

I even ask the LLM what tool is currently registered, it only say google_search and url_context.
