Ships with the iOS 26 beta and gives Claude the full PaperKit API for building markup experiences like the one in Notes or Screenshots. You get PaperMarkupViewController for the interactive canvas, PaperMarkup for serialization, and all the insertion controllers for shapes, text boxes, and annotations. Useful if you're adding annotation features to a document viewer, PDF editor, or any app that needs system-standard markup tools. The skill covers UIKit and SwiftUI integration, touch mode switching, and the data model operations. Since the framework is beta, treat API details as subject to change before public release.
