Concepts

Understand the design ideas behind Cua and how its main pieces fit together.

Use these pages when you want the model behind Cua rather than a step-by-step guide or API table. They explain what computer use means in Cua, how Cua Driver keeps the desktop usable while it acts, and how Cua Sandbox gives an agent a disposable computer.

Start with What is computer use? for the basic model. Read Best-effort background to understand Cua Driver's default behavior on a shared machine, then Capture and delivery modalities for the action axes. Read How sandboxes work when you need the model for disposable computers.
