What It Does

This app uses Gemini 2.5's computer use model capabilities to autonomously navigate websites and complete tasks. The example task searches for Kernel's company page on YCombinator and writes a blog post about their product.

Setup

1. Copy the environment file:

   cp .env-example .env

2. Add your API keys to .env:

   • KERNEL_API_KEY - Get from Kernel dashboard
   • GOOGLE_API_KEY - Get from Google AI Studio
   • OPENAI_API_KEY - Get from OpenAI platform

Running Locally

Execute the script directly with tsx:

npx tsx index.ts

This runs the agent without a Kernel invocation context and provides the browser live view URL for debugging.

Deploying to Kernel

1. Deploy the application:

   kernel deploy index.ts --env-file .env

2. Invoke the action:

   kernel invoke ts-stagehand-google-cua-agent google-cua-agent-task

The action creates a Kernel-managed browser and associates it with the invocation for tracking and monitoring.
