Step by step
- Open the GitHub repo and read the README.
- On a Mac (macOS 14 or newer): brew install franzenzenhofer/tap/bigarrow.
- Run bigarrow install-skill so Claude Code and Codex learn how to use it.
- Next time the agent needs you to click Allow or sign in, it points at the spot; or ask it to walk you through a setting step by step.
Watch out for
macOS only. Plain arrows need no permission, but pointing at a button by its name needs Accessibility for your terminal app, granted once in System Settings. It only points: it never clicks, types or captures your screen, so check each step yourself before you click.
