React Hooks Auditor
Professional audit tool to detect and fix React hooks anti-patterns, stale closures, and performance bottlenecks.
- Detect stale closures in useEffect and setInterval callbacks
- Identify and fix expensive derived state issues in useState
- Optimize re-renders caused by over-memoization or large Context objects
Free

- Downloadable skill package
- Works with Compatible with Claude Code, Cursor
Sample input
Audit the components in src/features/dashboard for any hooks issues, especially regarding stale closures or unnecessary re-renders.
Sample output
React Hooks Audit Report
Summary: 3 Findings (1 Critical, 1 High, 1 Medium)
[C-1] Stale Closure in useEffect
File: src/features/dashboard/Chart.tsx:22
Pattern: setInterval updates count without including it in deps.
Fix: Use functional update setCount(c => c + 1) or add count to deps.

About This Skill
Deep Analysis for React Hooks
React Hooks Auditor is a specialized development tool designed to catch the subtle, logic-breaking bugs that standard linters often overlook. While ESLint can catch syntax errors, this skill performs a deep conceptual audit of your React components and custom hooks to identify architectural anti-patterns like stale closures, derived state synchronization issues, and improper memoization.
What It Does
The auditor systematically scans your .jsx, .tsx, .js, and .ts files to evaluate how hooks are actually used. It analyzes:
- useEffect Logic: Finds missing cleanups, stale closure risks in intervals/listeners, and dependency array reference issues.
- State Management: Identifies redundant "derived state" patterns and suggests simpler
useMemooruseReduceralternatives. - Performance Pitfalls: Flags over-memoization of trivial primitives and identifies heavy context providers that trigger unnecessary re-renders.
- Rules of Hooks: Detects critical violations like hooks inside loops, conditions, or after early returns.
Actionable Output
Instead of cryptic error messages, the skill generates a detailed REACT_HOOKS_AUDIT.md report. Each finding is ranked by severity (Critical to Low) and includes a "Why it matters" explanation alongside a concrete, copy-pasteable code fix tailored to your specific implementation.
Why Use This Skill?
Manual code reviews for hooks are notoriously difficult and error-prone. This skill automates the mental model check required to ensure your hooks are safe for React's concurrent rendering features. It is faster than manual auditing and more context-aware than basic static analysis, making it an essential tool for pre-merge reviews and legacy code refactoring.
Use Cases
- Detect stale closures in useEffect and setInterval callbacks
- Identify and fix expensive derived state issues in useState
- Optimize re-renders caused by over-memoization or large Context objects
- Enforce Rules of Hooks in complex conditional logic or nested functions
Known Limitations
- Cannot detect logic errors in external libraries.
- Analysis limited to file-level scope (no deep cross-file trace).
- May flag intentional patterns as false positives.
