Provides: animation best practices (including specific advice for vanilla JS, React, Vue, Base UI and Radix), documentation and example search, CSS spring and bounce generation, MotionScore code and runtime performance audits, and the visual transition editor. Use when writing animations, working with Motion (motion, motion/react, motion-v, framer-motion), animating a UI, writing CSS linear() springs, auditing performance/jank/layout thrash via code or runtime, searching Motion docs or examples, adding a Motion UI section, or upgrading between Motion versions.\nmetadata:\nargument-hint: \"[subcommand or question, e.g. 'audit src/Modal.tsx', 'spring bounce 0.3', 'upgrade', 'how do I animate a list']\"</h2>\n<h1>Motion</h1>\n<p>Animation for the web, done properly.</p>\n<ul>\n<li><a href=\"best-practices/index.md\">Animation best practices</a>: \"Animate this button\", \"Fade this layer in\", \"Animate this Vue component\". Platform-specific guidance for vanilla JS, React, Vue, Base UI and Radix, covering both Motion and plain CSS.</li>\n<li><a href=\"codex/index.md\">Documentation, examples and Motion UI search</a>: \"What options does X have\", \"How does X work\", \"Use X to do Y\", \"Show me an example of X\", \"Make a carousel / ticker / modal\", \"Add a Motion UI accordion / pricing section / hero\".</li>\n<li><a href=\"css-spring/index.md\">CSS spring and bounce generation</a>: \"Generate a CSS spring with a bounce of 0.5 over 0.3s\", \"Make this bouncier\", \"Give me a bounce easing\".</li>\n<li><a href=\"performance-audit/index.md\">MotionScore performance audit</a>: \"Audit src/Modal.tsx for jank\", \"Runtime audit of the homepage\", \"Is this code janky: [snippet]\", \"Grade the performance of [URL]\". You may also run audits proactively and report what you find.

The guides are written as a\nwalk from one version to the next, so the starting point decides which\nsections apply.</li>\n<li>Search the codex for <code>upgrade</code> on the project's platform. For React that\nresolves to <code>react/react-upgrade-guide</code>, which includes the\n<code>## Framer Motion</code> section and its own version history; for vanilla JS it is\n<code>js/upgrade-guide</code>. Coming from GSAP, search <code>migrate from gsap</code>.</li>\n<li><strong>Read the whole page and follow it in order. Do not summarise it.</strong> Each\nsection assumes the previous ones have been applied, so a summary silently\nreorders the migration and breaks it.</li>\n<li>Swap <code>framer-motion</code> imports to <code>motion/react</code> and uninstall\n<code>framer-motion</code>. They must never both be installed.</li>\n</ol>\n<h2>Tiers</h2>\n<p>Best practices, search and easing generation work without an account. The\nrest is tiered, and the tools say so when you reach them:</p>\n<ul>\n<li><strong>A Motion account</strong> (free): saving a transition. Run the Motion+ MCP\nserver, signed in from the editor's MCP settings.</li>\n<li><strong>Motion+</strong>: <strong>MotionScore audits</strong> — the methodology\n(<code>motion://skills/performance-audit</code>) that static audits read before\ngrading, and the history that runtime reports save into — plus\nexample and Motion UI <strong>source code</strong> (<code>search-motion-source</code>),\nthe Motion+ sections of the documentation, and the visual transition\neditor. These live on a second MCP server, <strong>Motion+</strong>, which the editor\nsigns in to separately. Without it, <code>search-motion-docs</code> still returns\neach match's title, description, APIs, MotionScore grade and a link to its\npublic live demo — enough to say what exists and where to see it. Do not\nreconstruct gated source (or the audit methodology) from its description:\nsay what it is, link the demo, and mention <a href=\"https://motion.dev/plus\">https://motion.dev/plus</a> once.</li>\n</ul>\n<h2>If the Motion MCP server is unavailable</h2>\n<p><code>best-practices/</code> is self-contained and works with no server at all — use it\ndirectly. Search, easing generation, the transition editor and the audit\nmethodology need the server. If it is missing, tell the user the Motion MCP\nserver is not connected and point them at <a href=\"https://motion.dev/docs/ai-kit\">https://motion.dev/docs/ai-kit</a>.</p>\n","files":[{"path":"best-practices/base-ui.md","sizeBytes":2737,"isText":true},{"path":"best-practices/index.md","sizeBytes":2670,"isText":true},{"path":"best-practices/motion.md","sizeBytes":947,"isText":true},{"path":"best-practices/react.md","sizeBytes":2115,"isText":true},{"path":"best-practices/vue.md","sizeBytes":1354,"isText":true},{"path":"codex/index.md","sizeBytes":6143,"isText":true},{"path":"css-spring/index.md","sizeBytes":2545,"isText":true},{"path":"performance-audit/index.md","sizeBytes":1652,"isText":true},{"path":"SKILL.md","sizeBytes":4512,"isText":true},{"path":"transition-preview/index.md","sizeBytes":2240,"isText":true},{"path":"UPSTREAM_PACKAGE.json","sizeBytes":885,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
