# Animation Easing Language
- ## Use This Skill
-
- Use this skill for define motion timing, easing, duration, delay, and rhythm.
+ For substantial web work, reuse the [scoped web contract](../website-operating-rules/references/scoped-web-contract.md) when available; it replaces duplicated policy here. Match the requested scope and existing decisions; a missing optional sibling does not block this local procedure.
- ## Operating Contract
+ ## Use This Skill
- 1. Inspect the existing project before changing code.
- 2. Identify the motion stack, scroll behavior, component lifecycle, reduced-motion handling, and available verification commands.
- 3. Keep motion purposeful: clarify sequence, focus, depth, tactility, or product understanding.
- 4. Follow existing project conventions unless a change clearly improves the result.
- 5. Run available checks and visually inspect responsive/reduced-motion output when the change affects UI.
+ Use this skill to define motion timing, easing, duration, delay, and rhythm.
## Required Reference
Read [references/animation-easing-language-guide.md](references/animation-easing-language-guide.md) before making architectural or visible UI changes with this skill.
