Tool lets AI agents paint big arrows, boxes and text on screen
A GitHub project called big-arrow-on-the-screen, shared on Hacker News, is described as letting AI agents paint large arrows, boxes and text on the screen. The post drew 100-plus points in Hacker News's AI section, but the source gives no details on how it works, which agents it supports, or its license.
If agents can annotate the screen visually, it may be easier for humans or other agents to see which interface element they mean.
big-arrow-on-the-screen (bigarrow) is a macOS command-line tool, plus a skill for Claude Code and Codex, that draws an arrow and a sign on top of every window. Clicks go through, your keyboard focus stays put, and the arrow removes itself. MIT licensed.

Your AI agent can refactor a monorepo, write a migration and explain monads, but when it needs you to click one button it prints "please click Allow in the dialog" into a terminal you are not looking at.
bigarrowgives it a finger.
bigarrow point --element "Allow" --app "System Settings" --text "Franz, click Allow: Ghostty may control your Mac"
One transparent window above everything, on every display and every Space. Drawing needs no macOS permission at all. One Swift binary: no daemon, no menu-bar icon, no account, no telemetry, and, we checked twice, no AI inside. It is an arrow.
