Expo skills

Overview

Bundled official Expo agent skills live next to this file—one folder per topic. Open the matching leaf SKILL.md below before implementing; this file only routes.

Routing (symptom → leaf skill)

Read one primary leaf first; open a second only if the task clearly spans topics.

Tie-breakers

• “Upgrade Expo” or SDK mismatch errors → upgrading-expo before changing unrelated UI patterns.
• “Add screen / tab / modal” without deploy context → building-native-ui.
• “API on server” in Expo Router → expo-api-routes, not generic web Next.js docs.
• Styling system setup (Tailwind / NativeWind) → expo-tailwind-setup, not only building-native-ui.

When not to use this index

• Work is only backend (e.g. Supabase SQL, Edge auth) with no Expo surface change—use domain or Supabase skills instead.
• Questions are pure Git or product copy with no Expo/EAS/RN execution.

Common mistakes

• Stopping at this file—always read the leaf SKILL.md for procedures and constraints.
• Mixing web Next.js patterns with Expo Router without checking building-native-ui / expo-api-routes.
• Guessing NativeWind / Tailwind versions—expo-tailwind-setup is version-specific (v4 / v5).
