| description | Animation skill for Motion (prev Framer Motion) and CSS animation. 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.

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.
- 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.
- 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.
- 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.
- 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.
- 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.
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.
