How does this skill improve React performance?

It applies 12 prioritized rules targeting critical areas such as async waterfalls, bundle size, re-render logic, and DOM rendering efficiency.

Can this skill refactor existing code?

Yes, it is designed to be triggered during refactoring tasks to identify and fix suboptimal patterns in existing React components.

Does it support specific data fetching libraries?

Yes, it specifically promotes patterns for Tanstack Query to ensure automatic request deduplication and efficient state management.

How does it handle bundle size optimization?

The skill provides rules to avoid costly barrel file imports and guides the deferral of non-critical third-party libraries.

Is this skill specific to the Mastra framework?

While developed by the Mastra team, the performance guidelines are applicable to any modern TypeScript-based React application.

Design Tools

Optimizes React application performance through automated refactoring guidelines and high-impact implementation patterns.

About

The React Best Practices skill provides Claude with a comprehensive framework for writing, reviewing, and refactoring React code based on Mastra Engineering's performance standards. It organizes 12 high-impact rules across six prioritized categories—including waterfall elimination, bundle size optimization, and re-render management—to ensure that AI-generated frontend code is production-ready, efficient, and scalable. This skill is particularly useful for developers looking to automate performance audits and implement advanced patterns like Tanstack Query integration, lazy state initialization, and immutable state management.
