What problem does it solve? Designers, developers, and AI users often know what an animation looks or feels like but not what it is called, making it impossible to search for, specify, or prompt for the effect accurately. This Skill reverse-looks-up a loose description ('the bouncy thing when a popover opens') and returns the precise industry term ('Pop in'). ## Core Features & Use Cases - Reverse-lookup glossary: Covers entrances/exits, sequencing, transforms, transitions, scroll effects, feedback, easing, springs, looping, polish effects, performance, and motion principles, with verbatim authoritative one-line definitions. - Disambiguation of close terms: Contrasts confusable pairs like Morph vs Crossfade vs Shared element transition so the user picks the right word. - Register-neutral naming: Names effects without judging whether they fit a design system, deferring fit decisions to taste rules and build work to motion-craft skills. - Use Case: A user asks 'what's the iOS scroll that resists and snaps back called?' and receives 'Rubber-banding — Resistance and snap-back when you drag past a boundary (the iOS overscroll feel).' ## Quick Start Ask the assistant to name the animation effect you are describing, for example: 'What's it called when a thumbnail expands into a full card when tapped?'
