emilkowalski/skills ? reverse-engineered prompt

Build me a small installable skills package for design engineers that helps AI agents make better UI decisions, especially around animation and visual polish. I want it to feel like practical advice from someone with strong product taste, not generic design tips.

The main skill should guide an agent toward better choices for motion, easing, enter and exit behavior, timing, shadows, borders, and other tiny details that make an interface feel refined. Add another skill that reviews animations in a strict way, calls out what feels wrong, and explains how to fix it. The tone should be clear, opinionated, and useful for both designers and engineers.

Please include a clean README that explains what this is, why it matters, and how to install it with the usual skills command so someone can add it like emilkowalski/skill. Make the repo organized so more skills can be added later. If the skills format has changed, look up the current docs online and use the right structure.
