animation-system skillA

animation-system is agent-read markdown (skill) from lukaskellerstein/claude-my-marketplace: CSS and GSAP animation patterns for websites — ScrollTrigger, timelines, stagger effects, page transitions, micro-interactions, and performance optimization. Use when implementing animations for web design projects, when the user wants scroll-triggered animations, page load reveals, GSAP integration with React/Vite, animation planning, performance best practices, or when a design document specifies animations for sections..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
