Polishes existing motion against the transitions.dev token scale for duration, distance, scale, blur and easing, matching each value by what the motion does rather than the nearest number, with rules for open/close asymmetry, hover in and out, stagger and intent delays.

Audits animation code against Disney's 12 principles adapted for the web, checking timing, easing, physics and staging rules such as user-initiated motion under 300ms and ease-out entrances, and reports findings as file:line.

Audits Motion (Framer Motion) code against AnimatePresence rules: wrapping conditional exits, exit props and keys, the useIsPresent and usePresence hooks, choosing a mode, and coordinating nested exits. Reports findings as file:line. For React projects.

Audits CSS and JavaScript for pseudo-element and View Transitions API practices: content, positioning and z-index of ::before and ::after, replacing extra DOM nodes, expanding hit targets, naming and cleaning up view-transition-name, and ::backdrop styling. Reports findings as file:line.

Audits animation code for the right timing function: springs for gestures and interruptible motion, easing for system-driven state changes, linear for progress, and no animation for high-frequency interactions. Also checks spring parameters and durations. Reports file:line findings.
