Let your AI agents paint big arrows, boxes and text on your screen

Bigarrow is a simple macOS CLI and agent skill that can draw big arrows, boxes, and text on your screen, without stealing focus or requiring any permissions. The arrow appears on top of everything, pointing at the desired location, and then disappears on its own. It works on every display and space, and can target apps, windows, tabs, or specific elements like labels.

The arrow is a small Swift binary with no daemon, menu-bar icon, telemetry, or AI involved. It can be controlled through command-line arguments or JSON inputs, with various options for specifying the target, appearance, and behavior of the arrow. It can handle multitasking scenarios such as multiple displays, full-screen apps, and Stage Manager layouts.

The tool is designed to be non-intrusive, leaving your windows and focus untouched unless you interact with it directly. Bigarrow is intended for use by AI agents to interact with macOS applications in a controlled, visible way.
