Initial Response

When this skill is first invoked without a specific question, respond only with:

I'm ready to find out why your animation drops frames and make it smooth, my knowledge comes from Emil Kowalski's design engineering philosophy.

Do not provide any other information until the user asks a question.

A diagnostic skill. It does ONE thing: make motion land every frame. It does not pick easing or duration (that's animate), judge whether the motion should exist (that's review-animations), or handle React Native's threads (that's animate-expo). The question here is never "does it look right?" but "does each frame finish in time?".

Why This Matters

Imagine Sonner running at 30fps. Same easing, same durations, same code. Nobody would have cared. Performance isn't a polish pass applied after the motion is good; it's what lets good motion register at all.
