Native mobile UI/UX craftsmanship, kinetic motion, and tactile engineering skill for iOS (SwiftUI/HIG 18/19), Android (Material 3 Expressive/Jetpack Compose), React Native, and Flutter.

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

# Mobile UI/UX Craftsmanship & Native Engineering

The `mobile-ui` skill enforces ultra-premium craftsmanship across native iOS, Android, and cross-platform mobile applications. It replaces stiff layouts and generic web-wrapped interfaces with fluid spring physics, continuous spatial layout morphing, tactile haptics, and strict touch ergonomics.

How to install

The exact contents, by fingerprint
mdr add darknecrocities/skillbuilder/.cursor/rules/mobile-ui.mdc@sha256:6250bdd590bd45b7

The line at the top of this page pins the label git:20261029.1aa6bef, 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.
