Use when a web project needs animation or motion-tool selection across native CSS/WAAPI/View Transitions, Motion, Anime.js, GSAP, Lenis, scroll choreography, SVG/text animation, or synchronized motion systems.
インストールする前に、エージェントに与えられる指示の中身を確認できます。
Read references/tool-router.md and references/capability-matrix-2026.md and choose the smallest engine that cleanly implements the interaction.
Use CSS transitions/keyframes, WAAPI, CSS Scroll-Driven Animations or View Transitions when they cover the behavior cleanly.
Prefer for React state/layout/shared-layout, presence, gestures, springs and common scroll-linked UI motion. Read references/motion.md.
Prefer for precise lightweight timelines, staggered choreography, SVG/text/value animation and deterministic sequencing. Read references/animejs.md.
Prefer for advanced multi-part timelines, ScrollTrigger pin/scrub, Flip, SplitText, MotionPath and complex scroll/DOM/3D orchestration. Read references/gsap-lenis.md.
Use only when smooth scrolling or a normalized scroll signal is an intentional part of the experience. Native scroll remains the default.
For notable motion, record: Intent → Engine → Why → Reduced-motion behavior → Performance risk.
