A solid reference for the 12 classic Disney animation principles packaged as a Claude skill. You get squash and stretch, anticipation, staging, and the rest explained in about 30 seconds each, which is perfect when you're prototyping UI animations or need to explain why something feels off to a designer. The principles themselves are from the 1930s but they're still the foundation of what makes motion feel good, whether you're working on CSS transitions or After Effects. Think of it as a cheat sheet that keeps you from having to dig through "The Illusion of Life" every time you need a quick refresher on follow-through versus overlapping action.
