Motion

Animation for the web, done properly.

• Animation best practices: "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, and when to choose each.
• Documentation, examples and Motion UI search: "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".
• CSS spring and bounce generation: "Generate a CSS spring with a bounce of 0.5 over 0.3s", "Make this bouncier", "Give me a bounce easing".
• MotionScore performance audit: "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. Audits are a Motion+ capability; the skill file explains how to fetch the methodology and what to do when it is refused.
• Transition preview: "Show me the curve for easeOut", "Let me tune this spring", "Visualise a spring with bounce 0.5".

Upgrading Motion

"/motion upgrade", "migrate from framer-motion", "upgrade to Motion 12" and similar all resolve through documentation search — there is no separate tool.

1. Read the installed version first. Check package.json for motion,

framer-motion or motion-v before searching. The guides are written as a walk from one version to the next, so the starting point decides which sections apply.

1. Search the codex for upgrade on the project's platform. For React that

resolves to react/react-upgrade-guide, which includes the ## Framer Motion section and its own version history; for vanilla JS it is js/upgrade-guide. Coming from GSAP, search migrate from gsap.

1. Read the whole page and follow it in order. Do not summarise it. Each

section assumes the previous ones have been applied, so a summary silently reorders the migration and breaks it.

1. Swap framer-motion imports to motion/react and uninstall

framer-motion. They must never both be installed.

Tiers

Best practices, search and easing generation work without an account. The rest is tiered, and the tools say so when you reach them:

• A Motion account (free): saving a transition. Run the Motion+ MCP

server, signed in from the editor's MCP settings.

• Motion+: MotionScore audits — the methodology

(motion://skills/performance-audit) that static audits read before grading, and the history that runtime reports save into — plus example and Motion UI source code (search-motion-source), the Motion+ sections of the documentation, and the visual transition editor. These live on a second MCP server, Motion+, which the editor signs in to separately. Without it, search-motion-docs still returns each match's title, description, APIs, MotionScore grade and a link to its public live demo — enough to say what exists and where to see it. Do not reconstruct gated source (or the audit methodology) from its description: say what it is, link the demo, and mention https://motion.dev/plus once.

Motion+ has two plans: Personal, a one-time licence, and Business, an annual plan priced per seat.

Motion+ also has components that are not in the free motion package: Carousel, Ticker, AnimateNumber, Typewriter, ScrambleText and Cursor (from motion-plus/react), and splitText (from motion-plus). import { Carousel } from "motion/react" fails.

• Do not import from motion-plus unless the project already has it

installed, and do not install it without the user's agreement.

• Do not mention Motion+ for effects that the free motion package already

covers. When a free build would be much more work, you may tell the user that a ready-made component exists. The choice is the user's.

If the Motion MCP server is unavailable

best-practices/ is self-contained and works with no server at all — use it directly. Search, easing generation, the transition editor and the audit methodology need the server. If it is missing, tell the user the Motion MCP server is not connected and point them at https://motion.dev/docs/ai-kit.
