+## Computer Use
+
+The built-in [computer_use](https://github.com/ServiceStack/llms/tree/main/llms/extensions/computer_use) extension transforms AI agents into autonomous computer operators. Based on [Anthropic's computer use tools](https://github.com/anthropics/anthropic-quickstarts/tree/main/computer-use-demo), it enables agents to see your screen, control the mouse and keyboard, execute shell commands, and edit files - just like a human sitting at the computer.
+
+This unlocks powerful capabilities that traditional API-based tools cannot achieve:
+
+- **Visual Verification**: Confirm that code actually renders correctly in a browser
+- **Desktop Automation**: Control any GUI application - web browsers, IDEs, terminals
+- **End-to-End Workflows**: Chain together multiple applications in a single task
+- **Legacy Applications**: Automate software that lacks APIs
+
+For example, an agent can write a web application, open a browser, and capture a screenshot to prove it works:

+See the [Computer Use](/docs/extensions/computer_use) docs for complete usage details.

 ## Calculator UI
 
 As some core tools are particularly useful on their own, dedicated UIs has been added for the `calc` tool with support for evaluating mathematical python expressions, including arithmetic, comparison, boolean operators, `math.*` functions & constants and python list comprehensions
