# Motion Design This craft skill governs temporal behavior after UI/UX Designer has selected a visual direction. It does not choose or replace visual direction. All factual output follows the anti-hallucination skill: cite or mark UNKNOWN, never guess. ## Rule block Craft skill. Use it only for motion that communicates hierarchy, continuity, feedback, or state. Decorative motion requires an explicit design reason. Simple feedback can remain in the design record; nontrivial motion uses Motion Designer and `state/motion-<slug>.md`. 1. Record Trigger, User purpose, Frequency, Properties animated, Duration, Easing or spring values, Transform origin, Interruption and cancellation behavior, Final semantic state, Focus behavior, Reduced-motion replacement, Touch behavior, Performance limit, Before, after, and reason evidence, and Rejected alternatives. 2. Prefer transform and opacity. Any other property needs a documented reason and performance limit. Do not use `transition: all`. 3. Interrupted input must leave correct content, focus, and semantic/programmatic state. Touch behavior includes cancellation and an equivalent keyboard operation. 4. Reduced motion preserves the final state and essential feedback without the temporal effect. Focus changes remain visible and deterministic. 5. Motion Designer cannot change layout, content, typography, branding, or the selected visual direction. Return a boundary finding to UI/UX Designer if a change is needed. ## Re
