Is it compatible with React 19 features?

Absolutely. It considers the React Compiler, the Activity API, and useSyncExternalStore when analyzing your components and suggesting modern alternatives.

Does this skill support Next.js projects?

Yes, it includes specialized logic for Next.js that encourages the use of Server Components instead of useEffect for data fetching.

What kind of React issues does this skill detect?

It identifies nine specific anti-patterns including derived state in effects, expensive calculations that should be memoized, effect chains, and missing cleanup functions in data fetching.

Will it automatically modify my source code?

No, the skill follows a safety-first workflow where it flags findings and proposes fixes for your review before any changes are implemented.

セキュリティとテスト

Audits React codebases to eliminate redundant useEffect hooks and optimize component performance based on official best practices.

React Effects Auditor is a specialized diagnostic tool designed to scan React and Next.js applications for inefficient or incorrect useEffect patterns. Inspired by the official 'You Might Not Need an Effect' documentation, this skill identifies nine distinct anti-patterns—ranging from derived state issues to complex effect chains—and provides actionable refactoring suggestions. It helps developers prevent race conditions, memory leaks, and unnecessary re-renders while ensuring compliance with SOLID principles and modern React 19 standards.
