[sullyo]

Description

If you have computer use with another tool, the chat messages throw an error, due to invalid tool invocations

  const result = await streamText({
    model: anthropic("claude-3-5-sonnet-20241022"),
    maxSteps: 100,
    system:
      "You are a helpful assistant working on a computer. With the ability to navigate the web, type, click, and move the mouse.",
    messages: convertToCoreMessages(messages),
    tools: {
      computer: computerTool,
      navigation: {
        description: "Navigate to a specific url",
        parameters: z.object({
          url: z.string().describe("The url to navigate to"),
        }),
        execute: async ({ url }) => {
          const result = await computerControl({
            sessionId,
            action: "navigate",
            text: url,
          });
          return "Navigated to " + url;
        },
      },
    },
  });

You can invoke the tool once, but if you send 1 more chat message the error occurs:

 {"state":"call","toolCallId":"toolu_01MwvrJfwyFqk8nEV6BPqzEA","toolName":"navigation","args":
