+# Claude Agent SDK + Kernel Browser Automation
+
+This template demonstrates how to use the [Claude Agent SDK](https://platform.claude.com/docs/en/agent-sdk/overview) with [Kernel's](https://www.kernel.sh) browser automation capabilities.
+
+## Prerequisites
+
+### Claude Code Installation
+
+The Claude Agent SDK requires Claude Code to be installed. Follow the [official installation guide](https://platform.claude.com/docs/en/agent-sdk/overview#get-started):
+
+```bash
+# macOS/Linux/WSL
+curl -fsSL https://claude.ai/install.sh | bash
+```
+
+> **Note:** When deploying to Kernel, the app automatically installs Claude Code on the remote infrastructure.
+
+### API Keys
+
+You'll need:
+- **ANTHROPIC_API_KEY**: Get from the [Anthropic Console](https://console.anthropic.com/)
+- **KERNEL_API_KEY**: Get from the [Kernel Dashboard](https://dashboard.onkernel.com/api-keys)
+
+## Overview
+
+The Claude Agent SDK provides a powerful way to build AI agents that can autonomously perform tasks. This example combines it with Kernel's Playwright Execution API to create an agent that can browse the web and interact with websites.
+
+## Features
+
+- **Claude Agent SDK**: Uses Claude's agent capabilities with built-in tool management
+- **Kernel Browser**: Cloud-based browser with stealth mode and live view
+- **Playwright Execution**: Execute Playwright code directly in the browser VM
+- **In-process MCP Server**: Custom tool exposed via MCP for the agent to use
+- **Dual Execution**: Run locally via CLI or deploy as a Kernel app
+
+## Setup
+
+1. Install dependencies:
+
+```bash
+uv sync
+```
+
+2. Set up environment variables:
+
+```bash
+cp .env.example .env
+# Edit .env with your API keys
+```
+
+## Running Locally
+
+Run the agent directly from the command line:
+
+```bash
+# Default task (Hacker News top stories)
+uv run main.py
+
+# Custom task
+uv run main.py "Go to duckduckgo.com and search for 'Kernel browser automation'"
+
+# Another example
+uv run main.py "Go to https://github.com/trending and list the top 5 trending repositories"
+```
+
+## Deploying to Kernel
+
+Deploy and invoke the app on Kernel's infrastructure:
+
+```bash
+# Login to Kernel
+kernel login
+
+# Deploy the app with environment variables
+kernel deploy main.py --env-file .env
+
+# Invoke the action (logs stream automatically)
+kernel invoke py-claude-agent-sdk agent-task -p '{"task": "Go to https://news.ycombinator.com and get the top 3 stories"}'
+```
+
+## How It Works
+
+1. **Browser Creation**: A Kernel browser session is created with stealth mode enabled
+2. **MCP Server**: An in-process MCP server is created with an `execute_playwright` tool
+3. **Agent Execution**: The Claude Agent SDK runs with access to the Playwright tool
+4. **Task Completion**: Claude autonomously uses the tool to complete the given task
+5. **Cleanup**: The browser session is deleted when done
+
+When running on Kernel, the app first installs Claude Code on the remote infrastructure before executing the agent.
+
+## Example Tasks
+
+```bash
+# Get top Hacker News stories
+uv run main.py "Go to https://news.ycombinator.com and tell me the top 3 stories"
+
+# Search for something
+uv run main.py "Go to duckduckgo.com and search for 'Kernel browser automation'"
+
+# Extract data from a page
+uv run main.py "Go to https://github.com/trending and list the top 5 trending repositories"
+```
+
+## Environment Variables
+
+| Variable            | Description                                |
+| ------------------- | ------------------------------------------ |
+| `ANTHROPIC_API_KEY` | Your Anthropic API key for Claude          |
+| `KERNEL_API_KEY`    | Your Kernel API key for browser automation |
+
+## API Response
+
+When invoked via Kernel, the action returns:
+
+```json
+{
+  "result": "The agent's final response text",
+  "cost_usd": 0.1234,
+  "duration_ms": 45000
+}
+```
