animation-performance

animation-performance is an agent skill for keeping web animations inside the frame budget. It is a diagnostic skill: its question is not whether the motion looks right but whether each frame finishes in time. It animates composite-only properties, keeps motion off the main thread when the page is busy, and finds the cause when motion drops frames. It does not choose easing or duration, judge whether a motion should exist, or handle React Native's threads, which other skills in the collection cover. Its reasoning is that performance is not a polish pass applied after the motion is good, but what allows good motion to register at all. Use it when an animation stutters, a drawer or toast jank on a phone, or a page feels slow while something moves.
