Meaning-first animation with 3-tier hierarchy. CSS scroll-driven (animation-timeline: scroll()), View Transitions API, @starting-style DOM-insert, container scroll-state queries, prefers-reduced-motion mandatory on all animations.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 11 — Motion and Interaction System
Apply meaning-first CSS animations (scroll-driven, View Transitions, `@starting-style`) with mandatory `prefers-reduced-motion` on every animated surface.
## Motion serves one of three purposes
1. **Feedback** — confirm user action (button press, form submit, save)
2. **Continuity** — preserve spatial context across state changes (page transition, modal open)
3. **Delight** — express brand personality (hero parallax, signature reveal)
Anything else = AI slop; cut it.
## 3-Tier Hierarchy
- **Tier 1 — Functional** — feedback on every interaction (hover, focus, active, tap). Duration 100–200ms. Transform/opacity only.
- **Tier 2 — Choreographic** — page transitions, modal entrance, section reveal. Duration 300–500ms. View Transitions or `@starting-style`.
- **Tier 3 — Cinematic** — hero parallax, signature reveal, scroll-driven storytelling. Duration ≥600ms. Scroll-timeline.
Never stack 3 tiers on same surface. One cinematic per page.
## Mandatory `prefers-reduced-motion`
EVERY animation MUST honor `prefers-reduced-motion: reduce` — snap to final state, never hide content.
```css
@media (prefers-reduced-motion: reduce) {

How to install
mdr add heymegabyte/agent-skills/motion-and-interaction-system@sha256:8f971fc38cf7e80fThe line at the top of this page pins the label v2.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
