Motion Review Gate

Review motion as a pre-ship gate. This skill does not design a whole interface and does not rewrite unrelated frontend code.

Use it after implementation or during review when the diff includes animation, transitions, gestures, Lottie assets, interaction states, or motion-heavy UI polish. Pair it with browser-verification when the visual behavior must be checked in a real browser. When a diff includes drag, swipe, momentum, snap points, or another direct-manipulation gesture, also run fluid-interaction-review; this gate alone does not fully verify gesture physics.

Use For

• CSS transitions, keyframes, @starting-style, WAAPI, Framer Motion, Motion, or Lottie changes;
• drawers, popovers, menus, dropdowns, tooltips, toasts, command palettes, modals, hover states, press states, and gestures;
• frontend diffs where animation might hurt speed, accessibility, or product feel;
• checking whether motion should be removed rather than polished.
