- An AI agent displays an arrow and a guidance message at the top of the Mac screen to point to the button or window the user must press. According to the original, the arrow lets clicks pass through to the app below and disappears on its own after a set time.
- Installation consists of one Homebrew command and the bigarrow install-skill command, which registers a skill so that Claude Code and Codex can use this tool. The original says that building from source requires Xcode 16 or later and macOS 14 or later.
- The --element feature, which finds targets by button name, requires Accessibility permission. The original explains that this permission is granted not to bigarrow but to the app that runs the shell, such as Terminal, and states that drawing the arrow itself requires no permission.
- The figures 1.4 percent CPU usage, 87 automated tests, and 17 behavior checks are described by the project as confirmed on CI runners and similar environments, and they are not presented as results from an independent organization.
The condition that the find-by-button-name feature only works inside Chrome pages when accessibility mode is turned on catches my eye. If I'm working in Chrome day to day and want an agent to point at a page button, I'd want to check first whether name-based targeting actually works or whether I have to supply coordinates directly. The source has no accuracy measurements, so I think I'd need to run it myself to get a real sense of it.
