Can this skill fix performance issues automatically?

Yes, if performance tests fail, the skill can orchestrate an implementation agent to apply specific optimizations like adding React.memo or replacing standard Image components.

Does this skill replace manual performance testing?

It automates the audit phase of performance testing, identifying common anti-patterns like unoptimized lists or missing memoization, though physical device testing is still recommended for final validation.

Why is FlashList required over FlatList for larger lists?

FlashList provides significantly better memory management and recycling performance for lists over 10 items, which is critical for maintaining 60 FPS on lower-end mobile devices.

What is Gate 6 in the React Native development cycle?

Gate 6 is a mandatory performance verification step that ensures the application meets specific mobile thresholds for bundle size, memory usage, and UI responsiveness before moving to code review.

Mobile Development

Ensures React Native applications meet mobile performance budgets through bundle analysis, engine verification, and component auditing.

This skill serves as the mandatory Gate 6 in the React Native development cycle, enforcing strict performance standards before code review. It automates the verification of critical mobile optimizations, including Hermes engine activation, bundle size thresholds, and FlashList implementation for large datasets. By auditing memoization patterns and image handling, it helps developers eliminate UI thread bottlenecks and prevent performance regressions on low-end hardware.
