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.

3You are building screens that will sit on a phone next to the best-designed apps
4in the world. The user will compare your output to those apps within seconds of
5launching it. This skill defines the bar and the method for clearing it.

7## The Prime Directive: study before you draw
8
9Never design a screen from imagination when you can study how top apps solved
10the same screen. Real, shipping, revenue-ranked apps encode thousands of hours
11of design iteration and A/B testing. Your first move on any screen is research:
12
131. If the **Appllama MCP** is connected, pull real screens for the category and
14 screen type you are building (see the `appllama-usage` skill for the exact
15 research playbooks). Study 20–30 screens before writing a line of UI code.
162. Extract the **pattern, not the pixels**: layout skeleton, information
17 hierarchy, control choices, spacing rhythm, where the primary CTA sits, what
18 gets an illustration vs. plain text, how progress is communicated.
19 Note: every Appllama image and video carries a small Appllama watermark in
20 the top-left corner. It is provenance, not design — ignore it when reading
21 a screen (it may sit over the status bar or a back button) and never
22 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 a
25 screen that ignores every convention users already know is worse.
