This is the router you need whenever Claude Code touches iOS system APIs. It handles the coordination for Siri integration, Shortcuts, widgets, in-app purchases, camera access, photo library, audio, and haptics. The skill description emphasizes you MUST use it for any iOS system integration work, which suggests it's probably preventing Claude from making common mistakes when dealing with Apple's frameworks. With 183 installs and 945 GitHub stars, it's seeing real adoption. It passed Gen Agent Trust Hub and Socket audits but got a warning from Snyk, so check the security tab if you're integrating sensitive capabilities.
