Agent skill fromAppllama/appllama-skills
Build native-feeling, benchmark-quality mobile app screens (Expo / React Native). Use when designing or implementing any mobile UI — screens, flows, onboarding, paywalls, tab bars, sheets, settings, empty states — or when polishing motion, navigation, typography, dark mode, or perceived performance. Enforces Apple HIG fidelity, semantic colors, native controls, anti-slop discipline, navigation semantics (push vs replace, modal vs sheet vs overlay, the one-way doors where back must not exist), purposeful Reanimated motion, a full-motion simulator-verified iteration loop, and a study-real-apps-first workflow (pairs with the Appllama MCP). Trigger on "build a screen", "make this screen better", "design the onboarding", "wire up this flow", "polish the UI", "make it feel native", or any mobile design/implementation task.

1# Appllama App Design Skill23You are building screens that will sit on a phone next to the best-designed apps4in the world. The user will compare your output to those apps within seconds of5launching it. This skill defines the bar and the method for clearing it.67## The Prime Directive: study before you draw89Never design a screen from imagination when you can study how top apps solved10the same screen. Real, shipping, revenue-ranked apps encode thousands of hours11of design iteration and A/B testing. Your first move on any screen is research:12131. If the **Appllama MCP** is connected, pull real screens for the category and14 screen type you are building (see the `appllama-usage` skill for the exact15 research playbooks). Study 20–30 screens before writing a line of UI code.162. Extract the **pattern, not the pixels**: layout skeleton, information17 hierarchy, control choices, spacing rhythm, where the primary CTA sits, what18 gets an illustration vs. plain text, how progress is communicated.19 Note: every Appllama image and video carries a small Appllama watermark in20 the top-left corner. It is provenance, not design — ignore it when reading21 a screen (it may sit over the status bar or a back button) and never22 reproduce it in anything you build.233. Then design **your** screen: same proven skeleton, your product's voice.24 Copying a competitor's screen 1:1 is both lazy and legally risky; shipping a25 screen that ignores every convention users already know is worse.26…
