-## History Property
-
-For compatibility with evaluation systems, CodeAgent also provides a `history` property that mimics the Agent's history format:
-
-```python
-# Access history property (returns mock AgentHistoryList)
-history = agent.history
-
-# Access the history list
-history.history          # List of CodeAgentHistory objects (converted to dict-like objects)
-history.usage            # UsageSummary with token usage information
-
-# Access individual history items
-for step in history.history:
-    # Model output (code generated by LLM)
-    if step.model_output:
-        code = step.model_output.model_output
-        full_response = step.model_output.full_response
-    
-    # Execution results
-    for result in step.result:
-        output = result.extracted_content
-        error = result.error
-        is_done = result.is_done
-        success = result.success
-    
-    # Browser state
-    url = step.state.url
-    title = step.state.title
-    screenshot_path = step.state.screenshot_path
-    screenshot = step.state.get_screenshot()  # Returns base64 string
-    
-    # Metadata (timing and tokens)
-    if step.metadata:
-        duration = step.metadata.duration_seconds
-        input_tokens = step.metadata.input_tokens
-        output_tokens = step.metadata.output_tokens
-```
-
-## Screenshots
-
-Access screenshot paths using the agent's `screenshot_paths()` method:
-
-```python
-# Get all screenshot paths
-paths = agent.screenshot_paths()
-
-# Get last N screenshots
-last_3 = agent.screenshot_paths(n_last=3)
-```
-
-## Complete Example
-
-```python
-import asyncio
-from browser_use import CodeAgent
-
-async def main():
-    agent = CodeAgent(task="Extract products from example.com")
-    session = await agent.run()
-    
-    # Check completion
-    if session.namespace.get('_task_done'):
-        print("✅ Task completed!")
-        print(f"Result: {session.namespace.get('_task_result')}")
-    else:
-        print("⚠️ Task incomplete")
-    
-    # Review all code execution
-    print(f"\nExecuted {len(session.cells)} cells:")
-    for i, cell in enumerate(session.cells, 1):
-        print(f"\nCell {i}:")
-        print(f"  Status: {cell.status}")
-        if cell.error:
-            print(f"  ❌ Error: {cell.error}")
-        elif cell.output:
-            print(f"  ✓ Output: {cell.output[:100]}...")
-    
-    # Access extracted data
-    if 'products' in session.namespace:
-        products = session.namespace['products']
-        print(f"\n📦 Extracted {len(products)} products")
-    
-    # Get screenshots
-    screenshots = agent.screenshot_paths()
-    print(f"\n📸 Captured {len([p for p in screenshots if p])} screenshots")
-
-asyncio.run(main())
-```
