justinwetch/HIGAgentSkills
A skill library that gives AI coding agents access to Apple Human Interface Guidelines, including a /duo command for adapting iOS apps to the folding iPhone Duo.

The project packages 157 source-reviewed Apple HIG references as an installable agent skill, with a guided /duo workflow that walks an AI coding agent through assessing an existing iOS app’s screens, matching them to Apple’s Duo guidance, recommending changes, and implementing them in SwiftUI or UIKit. It is designed to be installed into agent environments via a copy-paste prompt and exposes a slash command for the Duo redesign task. The repository covers iOS, iPadOS, macOS, tvOS, visionOS, and watchOS guidance.
