This is the code base of AgentNetTool in OpenCUA: Open Foundations for Computer-Use Agents. AgentNetTool is a cross-platform software to annotate computer-use agent tasks. It can record the full video with all the keyboard and mouse inputs as well as the other important system meta data (HTML, A11ytree elements, ...) during the annotator performing the task.
