Design vs Frontend · both proven

slides vs vercel-react-native-skills

Both skills were run through Claude twice: once on a fixed brief without the skill, once with it. The briefs differ because each is written for the job the skill claims to do, so compare each skill against its own baseline, then decide which difference matters for your work. They are in different categories, so this is a choice of job, not a head-to-head on the same job.

Brief: “Review and improve this React Native screen, and present the findings and the improved code as a single HTML page. ```jsx export default function Feed() { const [posts, setPosts] = useState([]); useEffect(() => { fetch(API + '/posts').then(r => r.json()).then(setPosts); }); return ( <ScrollView> {posts.map(p => ( <View> <Image source={{ uri: p.image }} style={{ width: '100%', height: 300 }} /> <Text onPress={() => navigation.navigate('Post', { post: p })}>{p.title}</Text> </View> ))} </ScrollView> ); } ```”
