Big Arrow on the Screen

What is Big Arrow on the Screen?

Big Arrow on the Screen is a macOS command-line tool that draws large arrows, boxes, and text directly over application windows. It functions as a visual bridge between terminal-based AI agents and the graphical user interface. When an agent needs you to click a button, it generates a transparent overlay pointing exactly to the target element.

The overlay sits above all windows and desktop spaces while allowing mouse clicks and keyboard focus to pass through to the underlying app. Once clicked, the arrow automatically disappears. The tool requires no macOS permissions, runs as a single Swift binary, and contains no background services, accounts, or telemetry.

It includes ready-to-use skills for Claude Code and Codex, enabling coding agents to direct human users through system settings, application menus, or web interfaces. The project is published under the MIT license.
