What problem does it solve? Interfaces often feel dead or untrustworthy because small interaction details like button feedback, loading states, and toggle behavior are overlooked. This Skill provides a structured framework, based on Dan Saffer's four-part model, to design, score, and fix these contained product moments. ## Core Features & Use Cases - Four-Part Design Framework: Structure any microinteraction around Triggers, Rules, Feedback, and Loops & Modes, with ethical boundaries for each. - Scored Diagnostic Audit: Evaluate any microinteraction against an 8-row diagnostic checklist and compute a 0-10 score with specific fixes for each failure. - Detailed Case Studies: Reference implementation-ready breakdowns of form submission, toggles, pull-to-refresh, loading states, and toast notifications, including animation specs, accessibility requirements, and edge cases. - Use Case: When a user says the interface feels unresponsive, audit the save button flow, identify missing sub-100ms feedback and absent error states, then specify exact visual states, timing, and copy for each transition. ## Quick Start Audit the loading state and submit button feedback in my checkout form using the microinteractions framework and tell me the score with fixes.
