How do I install the React Hooks skill?

Run npx skillmds@latest add comeonoliver/react-hooks in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is React Hooks safe to use?

This skill has not completed SkillMD's automated safety review yet. Independent scanners report: SkillSpector: PASS, Skill Scanner: PASS. Capability flags: makes network calls. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with React Hooks?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is React Hooks free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

React Hooks

Standards for efficient React functional components and hooks usage. Use when writing custom hooks, optimizing useEffect, or working with useMemo/useCallback in React. (triggers: **/*.tsx, **/*.jsx, useEffect, useCallback, useMemo, useState, useRef, useContext, useReducer, useLayoutEffect, custom hook)

React Hooks Expert

Priority: P0 (CRITICAL)

You are a React Performance Expert. Optimize renders and prevent memory leaks.

Implementation Guidelines

Dependency Arrays: exhaustive-deps is Law. Objects/arrays are recreated each render, causing infinite loops if not handled. Fix by ensuring objects/arrays are memoized with useMemo before putting them in deps, or using useRef for stable refs.
Memoization: useMemo for heavy calc (expensive computed values) and useCallback for props (stabilize function references for memoized children). Measure first to avoid premature complexity.
Custom Hooks: Extract logic starting with use... — use useState for internal state and return only what's needed.
useEffect: Sync with external systems ONLY. Cleanup required for subscriptions/event listeners. Return cleanup function from the effect. Use AbortController for fetch cleanup to prevent state updates after unmount.
useRef: Mutable state without re-renders (DOM, timers, tracking).
useMemo/Callback: Measure first. Use for stable refs or heavy computation.
Stability: Use useLatest pattern (ref) for event handlers to avoid dependency changes; see the useLatest ref pattern example for a reference implementation.
Concurrency: useTransition / useDeferredValue for non-blocking UI updates.
Initialization: Lazy state useState(() => expensive()).

Performance Checklist (Mandatory)

Rules of Hooks: Called at top level? No loops/conditions?
Dependencies: Are objects/arrays memoized before passing to deps?
Cleanup: Do useEffect subscriptions return cleanup functions?
Render Count: Does component re-render excessively?

Anti-Patterns

No Missing Deps: Fix logic, don't disable linter.
No Complex Effects: Break tailored effects into smaller ones.
No Derived State: Compute during render, don't useEffect to sync state.
No Heavy Init: Use lazy state initialization useState(() => heavy()).
