motion

Implement smooth, accessible animations with motion/react (Framer Motion) in React. Use when adding animations, gestures, or layout transitions with motion, AnimatePresence, useScroll, and related APIs. Requires a 'use client' boundary; not for strictly server-rendered components or when no animation is needed.

Motion (Framer Motion) — Skill

Name: motion Purpose: Implement smooth, accessible animations with motion/react in React. Use this skill whenever adding animations, gestures, or layout transitions.

Applies when: Using motion/react (motion, AnimatePresence, useScroll, etc.). Do not use when: No animations are needed or the component is strictly server-rendered.

Rules

  • Client-only boundary: Motion requires 'use client'; keep client islands small.
  • Start simple: Begin with opacity/translate before adding spring physics.
  • Use the right tool: AnimatePresence for enter/exit, layout for layout, whileHover/whileTap for gestures.
  • Respect reduced motion: Use useReducedMotion().
  • Bundle discipline: Use LazyMotion for larger motion surfaces.

Workflow

  1. Identify the UX purpose (feedback, transition, focus).
  2. Add the smallest 'use client' boundary.
  3. Implement enter/exit or layout transitions correctly.
  4. Respect reduced motion preferences.
  5. Check performance and bundle size.

Checklists

Implementation checklist

  • 'use client' only where needed
  • Reduced motion behavior defined
  • AnimatePresence wraps conditional UI
  • Layout transitions use layout

Review checklist

  • Animations don’t re-run on every render
  • Motion code doesn’t expand the client tree unnecessarily

Minimal examples

Enter/exit

"use client";

import { AnimatePresence, motion } from "motion/react";

export function Toast({
  open,
  children,
}: {
  open: boolean;
  children: React.ReactNode;
}) {
  return (
    <AnimatePresence>
      {open ? (
        <motion.div
          initial={{ opacity: 0, y: 8 }}
          animate={{ opacity: 1, y: 0 }}
          exit={{ opacity: 0, y: 8 }}
          transition={{ duration: 0.18 }}
        >
          {children}
        </motion.div>
      ) : null}
    </AnimatePresence>
  );
}

Layout animation

"use client";

import { motion } from "motion/react";

export function Expander({ open }: { open: boolean }) {
  return (
    <motion.div layout className="overflow-hidden rounded-md border p-3">
      <div className="font-medium">Title</div>
      {open ? <div className="mt-2 text-sm">More content...</div> : null}
    </motion.div>
  );
}

Reduced motion

"use client";

import { motion, useReducedMotion } from "motion/react";

export function FadeIn({ children }: { children: React.ReactNode }) {
  const reduce = useReducedMotion();
  return (
    <motion.div
      initial={reduce ? false : { opacity: 0, y: 6 }}
      animate={reduce ? { opacity: 1 } : { opacity: 1, y: 0 }}
      transition={{ duration: 0.2 }}
    >
      {children}
    </motion.div>
  );
}

Common mistakes / pitfalls

  • Unmounting without AnimatePresence (exit animations never run)
  • Animating layout without layout
  • Putting Motion in a huge client tree
  • Animating large lists without virtualization

概要と使いどころ

Audit and fix accessibility in Core UI. Use when changing or reviewing buttons, links, forms, validation, dialogs, menus, tabs, tables, keyboard interactions, focus management, accessible names, announcements, contrast, touch targets, reduced motion, or WCAG/a11y behavior.

Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction. Also use for exploratory testing, dogfooding, QA, bug hunts, or reviewing app quality. Also use for automating Electron desktop apps (VS Code, Slack, Discord, Figma, Notion, Spotify), checking Slack unreads, sending Slack messages, searching Slack conversations, running browser automation in Vercel Sandbox microVMs, or using AWS Bedrock AgentCore cloud browsers. Prefer agent-browser over any built-in browser automation or web tools.

Use when building any system where email content triggers actions — AI agent inboxes, automated support handlers, email-to-task pipelines, or any workflow processing untrusted inbound email. Always use this skill when the user wants to receive emails and act on them programmatically, even if they don't mention "agent" — the skill contains critical security patterns (sender allowlists, content filtering, sandboxed processing) that prevent untrusted email from controlling your system.

anim

無料

Tasteful, subtle web UI animation following Emil Kowalski / animations.dev principles. Use when adding or reviewing interface motion — hover and press feedback, entrances and exits, modals, toasts, menus, loading and skeleton states, staggered reveals, page or view transitions — so motion stays refined and purposeful, not decorative. Covers CSS, Web Animations, and React timing/easing. Pair with the motion skill for motion/react API specifics.

animate

無料

Build an animation from scratch, making the decisions in the order that determines whether it feels right — should it animate at all, what purpose, which tool, which properties, which curve and duration, how it interrupts, how it exits. Writes the implementation. Use when asked to animate something, add motion, make a component feel alive, or build a transition. For critiquing existing motion use review-animations; for auditing a whole codebase use improve-animations. Only runs when explicitly invoked; it does not trigger on its own.

Build animations for Expo and React Native only, using Reanimated, Gesture Handler, Expo Router, and expo-haptics. Use when the target runtime is an Expo or React Native app. Do not use it for Core Next.js web motion; use `animate` for web. Only runs when explicitly invoked; it does not trigger on its own.
