Design tokens and a drop-in SwiftUI token module for iPhone Duo, Apple's foldable, that adapt by size class instead of by device. Covers a 4-point spacing scale, system margins and gutters with a wider gap at the fold, even-column layout grids (4 compact, 8 regular) with spans, one type scale with Dynamic Type for the 5.4-inch outer and 7.6-inch inner display, Liquid Glass usage and legibility (glassEffect, GlassEffectContainer, regular vs clear, dimming, tint), ConcentricRectangle and…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# duo-design-system One set of design tokens for both iPhone Duo displays. The tokens follow the size class and Dynamic Type size of the view that reads them. They never ask which display, device or screen the app is on. Load other skills for neighbouring work: `duo-layout` (size classes, safe areas, reserved regions, `ArrangementView`), `duo-patterns` (which layout, feed reflow), `duo-navigation` (vertical bars), `duo-design-review` (checking screenshots against the rules). Labels: *measured* means we ran it on the iOS 27.1 simulator runtime (offscreen renders and command-line checks, or the iPhone Duo simulator in an earlier skill). *Derived* means arithmetic on measured or Apple numbers. *Duology default* means Apple gives no number and we picked one. *Unverified* means we could not confirm it. Sources: [reference/sources.md](https://github.com/Kimeur/duology/blob/main/reference/sources.md). ## Rules …

How to install
mdr add kimeur/duology/duo-design-system@sha256:afb1fdceb357add6The line at the top of this page pins the label git:20261019.5ff724c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
