Expo iOS HIG Verifier

A read-only static checker that scans an Expo (React Native) project for violations of the expo-ios-hig rules and reports them grouped by severity, with file:line locations and links to the rule that explains the fix. It is the automated counterpart to the expo-ios-hig reference skill: that skill teaches the rules; this one checks them.

When to Apply

Run this skill when:

• The user asks to check, lint, audit, or review an Expo app for HIG compliance or native feel
• Before merging or shipping Expo iOS UI changes, as a quality gate
• After scaffolding new screens, to confirm they stay native
• Investigating why an Expo app "feels like a web wrapper" or "feels like Android"

It is read-only — it never modifies the target project, so it is safe to run unsupervised.
