This gives Claude Code the ability to automate iOS Simulator interactions through AXe, a CLI tool that uses Apple's Accessibility APIs. The key workflow is running describe_ui first to get precise element coordinates before any taps or gestures, which the skill emphasizes repeatedly because guessing coordinates from screenshots doesn't work reliably. It's a single binary with no daemon required, so setup is straightforward via Homebrew. If you're doing any automated testing or interaction with iOS apps in the simulator, this beats manually clicking around or trying to script things with less reliable methods. The 948 GitHub stars suggest it's solving a real pain point for iOS developers.
