What problem does it solve? Users often know what a motion effect looks or feels like but not its proper name, making it hard to prompt an AI, brief a designer, or search for implementation guidance. This Skill reverse-looks-up the precise term from a curated glossary of web animation vocabulary. ## Core Features & Use Cases - Reverse glossary lookup: Converts loose descriptions like "the bouncy thing when a popover opens" into exact terms such as Pop in or Rubber-banding. - Disambiguation of close terms: Contrasts competing terms (e.g., Clip-path vs Mask, Morph vs Crossfade) so the user can pick the right one. - Comprehensive coverage: The glossary spans entrances, sequencing, transforms, transitions, scroll effects, feedback, easing, springs, looping, polish, performance, and motion principles. - Use Case: A user asks "what's it called when one image turns into another?" and receives Morph as the primary term with Crossfade and Shared element transition as alternates. ## Quick Start Ask the assistant to name the animation effect you are describing, for example by saying what is it called when a scroll resists and snaps back at the edge.
