React Hooks Auditor

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 useMemo or useReducer alternatives.
• 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.
