What problem does it solve? Motion code that technically runs can still feel wrong — wrong easing, wrong origin, dropped frames, or animations that fire too often. This Skill reviews animation changes in a diff or PR against a defined craft bar and produces a structured verdict instead of vague feedback. ## Core Features & Use Cases - Ten-Standard Review: Checks every animation against rules covering justification, frequency, easing, duration, origin, interruptibility, GPU usage, accessibility, asymmetry, and cohesion. - Flag-on-Sight Patterns: Instantly catches known anti-patterns like transition: all, scale(0) entrances, ease-in on UI, and keyframes on toasts or toggles. - Structured Output: Produces a findings table with Before/After/Why columns citing file:line, followed by a tiered verdict ending in an explicit Block or Approve decision. - Use Case: A teammate opens a PR adding a dropdown transition and a modal entrance. Run this Skill to get a findings table flagging the ease-in curve and centered transform origin, plus a Block verdict with the exact fixes to request. ## Quick Start Review the animation changes in this pull request and tell me whether the motion should ship.
