bigarrow is a macOS CLI tool that draws persistent arrows, boxes, and text overlays on top of any window to guide users through UI actions, specifically designed for AI agents to point out where humans need to click or act. It combines accessibility APIs for element targeting with a transparent overlay system, and includes features like auto-dismissal, copy-paste buttons, and a Claude Code skill for agent integration. The project is notable for its clear focus on the emerging human-in-the-loop agent interaction problem and its thorough, example-rich documentation.

Target audience: AI agent developers, macOS power users, and developers building human-in-the-loop automation workflows
