-# cu-playwright-python
+# Kernel Python Sample App - Computer Use
+
+This is a simple Kernel application that implements a prompt loop using Anthropic Computer Use.
+
+It generally follows the [Anthropic Reference Implementation](https://github.com/anthropics/anthropic-quickstarts/tree/main/computer-use-demo) but replaces `xodotool` and `gnome-screenshot` with Playwright.
+
+# cu-playwright-python
+
+Computer Use Agent for Python - Browser automation with Claude using Anthropic's Computer Use capabilities.
+
+This library provides a clean, simple interface to Anthropic's Computer Use capabilities, allowing Claude to interact with web pages through Playwright. It's the Python equivalent of [cu-playwright-ts](https://github.com/anthropics/cu-playwright-ts).
+
+## Features
+
+- 🤖 **AI-Powered Browser Automation**: Let Claude control web browsers with natural language
+- 🎯 **Simple API**: Clean, intuitive interface for complex browser interactions
+- 📊 **Structured Responses**: Get validated data back using Pydantic models
+- 🛠️ **Built on Playwright**: Reliable browser automation underneath
+- ⚡ **Async/Await**: Modern Python async support
+
+## Installation
+
+```bash
+pip install cu-playwright-python
+```
+
+You'll also need to install Playwright browsers:
+
+```bash
+playwright install chromium
+```
+
+## Quick Start
+
+```python
+import asyncio
+import os
+from playwright.async_api import async_playwright
+from cu_playwright_python import ComputerUseAgent
+
+async def main():
+    # Set up your Anthropic API key
+    api_key = os.getenv("ANTHROPIC_API_KEY")
+
+    async with async_playwright() as playwright:
+        browser = await playwright.chromium.launch(headless=False)
+        page = await browser.new_page()
+
+        # Create agent
+        agent = ComputerUseAgent(
+            api_key=api_key,
+            page=page
+        )
+
+        # Navigate and interact
+        await page.goto("https://example.com")
+        result = await agent.execute("What is the title of this page?")
+        print(result)
+
+        await browser.close()
+
+asyncio.run(main())
+```
+
+## Usage
+
+### Basic Text Responses
+
+```python
+# Simple queries return text
+result = await agent.execute("Describe what you see on this page")
+print(result)  # "This page contains a header with..."
+```
+
+### Structured Data with Pydantic
+
+```python
+from pydantic import BaseModel
+
+class ProductInfo(BaseModel):
+    name: str
+    price: float
+    in_stock: bool
+
+# Get structured data back
+product = await agent.execute(
+    "Find the main product on this page and extract its details",
+    schema=ProductInfo
+)
+print(f"Product: {product.name}, Price: ${product.price}")
+```
+
+### Advanced Options
+
+```python
+result = await agent.execute(
+    "Fill out the contact form with realistic data",
+    system_prompt_suffix="Be extra careful with form validation",
+    thinking_budget=2048  # More reasoning tokens
+)
+```
+
+## API Reference
+
+### ComputerUseAgent
+
+The main class for browser automation with Claude.
+
+#### Constructor
+
+```python
+ComputerUseAgent(
+    api_key: str,              # Anthropic API key
+    page: Page,                # Playwright page instance
+    model: str = "claude-sonnet-4-20250514"  # Claude model to use
+)
+```
+
+#### execute()
+
+Execute a computer use task with Claude.
+
+```python
+async def execute(
+    query: str,                           # Task description
+    *,
+    schema: Optional[Type[BaseModel]] = None,  # Pydantic model for structured responses
+    system_prompt_suffix: str = "",       # Additional system instructions
+    thinking_budget: int = 1024           # Token budget for Claude's reasoning
+) -> Union[str, BaseModel]
+```
+
+**Parameters:**
+- `query`: Natural language description of what you want Claude to do
+- `schema`: Optional Pydantic model class for structured responses
+- `system_prompt_suffix`: Additional instructions appended to the system prompt
+- `thinking_budget`: Token budget for Claude's internal reasoning process
+
+**Returns:**
+- `str`: When no schema is provided
+- `BaseModel`: Instance of the provided schema class when schema is specified
+
+## Examples
+
+See [example.py](example.py) for comprehensive usage examples including:
+
+- Basic page interactions
+- Structured data extraction with Pydantic models
+- Complex multi-step workflows
+- Custom system prompts
+
+## Requirements
+
+- Python 3.9+
+- An Anthropic API key ([get one here](https://console.anthropic.com/))
+- Playwright browsers installed
+
+## Model Compatibility
+
+This library works with Anthropic's Computer Use compatible models:
+
+- `claude-sonnet-4-20250514` (recommended)
+- Other Computer Use enabled models
+
+See [Anthropic's documentation](https://docs.anthropic.com/en/docs/agents-and-tools/tool-use/computer-use-tool#model-compatibility) for the latest model compatibility information.
