Does it support troubleshooting EAS local builds?

Yes, it includes detailed guides for troubleshooting environment variable issues (.easignore) and tar metadata errors during local EAS builds.

How does it help with Firebase issues in mobile apps?

It provides specific checks for Auth persistence, module naming consistency, and Firestore emulator connectivity (10.0.2.2 vs localhost) for different platforms.

Can it help with app performance and lag?

Yes, it includes specialized logging patterns to track component re-renders, prop changes, and hook executions to identify unnecessary UI updates.

What types of apps does this skill support?

It is specifically designed for React Native applications, with extensive support for both Expo-managed projects and bare React Native workflows.

Mobile Development

Diagnoses and resolves complex React Native and Expo issues including white screens, Firebase connectivity, and performance bottlenecks.

The rn-debug skill provides a systematic troubleshooting framework for React Native and Expo applications, specifically targeting common pain points like the 'White Screen of Death,' Firebase configuration errors, and EAS build failures. It equips Claude with structured workflows to investigate native module mismatches, stabilize Firestore connections, and debug complex re-rendering cycles using standardized logging patterns. By integrating with MobileMCP for visual inspection and providing specific fixes for emulator connectivity, this skill streamlines the entire mobile debugging lifecycle for developers.
