What problem does it solve? Automating GUI tasks normally requires taking over the user's mouse and keyboard, interrupting their work. This Skill lets an agent click, type, scroll, and drag inside native desktop apps in the background, so the user keeps working while tasks complete on macOS, Windows, or Linux. ## Core Features & Use Cases - Element-indexed interaction: Capture screenshots with numbered accessibility-tree overlays and click elements by index instead of unreliable pixel coordinates. - Background-first input delivery: Actions route without raising windows, switching virtual desktops, or stealing focus, with a structured verify-and-escalate ladder (background → pixel → foreground) when delivery fails. - Cross-platform support: Works with any tool-capable model across macOS (AX), Windows (UIA), and Linux (AT-SPI), powered by cua-driver. - Use Case: Ask the agent to fill out a form in a native desktop app or navigate a Figma canvas while you continue typing in your editor in another window. ## Quick Start Ask the agent to capture the screen of a specific app and click a numbered element, for example: capture Chrome and click the Sign In button.
