Can it fix React re-render issues automatically?

Yes, it detects common causes of re-renders, such as inline functions in props or missing memoization, and offers to refactor them using useCallback and React.memo.

Does it support code splitting suggestions?

Yes, it identifies components that would benefit from dynamic imports and lazy loading to improve the initial loading performance of your application.

Is this skill compatible with Storybook 9?

Yes, it is specifically designed for the Storybook 9 ecosystem as part of the Storybook Assistant suite for Claude Code.

How does this skill help reduce bundle size?

The skill identifies heavy 'kitchen-sink' packages like Lodash or Moment.js and suggests tree-shaking friendly imports or lighter alternatives like date-fns and Day.js.

设计工具

Optimizes Storybook component performance and bundle size using AI-powered analysis and automated code fixes.

The Performance Analysis skill provides an automated audit for React components within Storybook, identifying critical bottlenecks such as heavy dependencies, unnecessary re-renders, and inefficient bundle sizes. It goes beyond simple reporting by providing actionable, AI-powered suggestions—like replacing Moment.js with date-fns or implementing React.memo—to ensure your UI library remains lightweight and performant. By scanning imports and render logic, it helps developers achieve up to a 40% reduction in bundle size while improving the overall responsiveness of their components.
