Kernel browsers can be configured to stealth mode, which adds a high performant residential proxy and auto-CAPTCHA solver to your instances. To turn on stealth mode, set its flag in your app code when instantiating Kernel: 
const kernelBrowser = await kernel.browsers.create({
    invocation_id: ctx.invocation_id,
    stealth: true,
});
Anthropic Computer Use stops when it runs into a CAPTCHA. Use Kernel’s auto-captcha solver by adding this to your prompt:"If you see a CAPTCHA or similar test, just wait for it to get solved automatically by the browser."
