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. bigarrow gives 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.
