What is skills?

This repository is a set of instruction files, called skills, meant to teach AI coding assistants good taste in interface design and animation. It is written by a designer with experience at companies like Vercel and Linear, and it packages that hands-on knowledge into files an AI agent can read and follow when it helps build a website or app. The core idea is that AI agents are often technically capable but make small design mistakes that add up: picking the wrong easing curve for an animation, using a solid border instead of a soft shadow, or moving something in a way that just feels off. Each skill in the collection explains these kinds of mistakes and how to avoid them, so an agent following the skill produces more polished, professional looking results. The collection includes several distinct skills. One covers general animation and design principles. Another reviews existing animations in a codebase against a strict set of rules. A third audits an entire project's animations across categories like timing, performance, accessibility, and consistency, then writes out prioritized, step by step plans that another AI agent can carry out without needing any design judgment of its own. There is also a skill for finding places in an interface that would genuinely benefit from added motion, one that teaches the vocabulary needed to describe the animation you want to an AI, a skill based on Apple's own interface design guidance, and a skill that helps an agent choose a trustworthy UI library instead of building components from scratch. Installing the skills is done with a single command line tool built for this purpose. The audience is designers and engineers who use AI coding tools and want those tools to produce better looking, more carefully animated interfaces rather than generic or awkward ones.
