The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.
--- name: animation-principles description: Apply animation principles — easing, staging, follow-through — to one specific UI motion. Use when tuning how an animation feels. For product-wide duration and easing tokens use `motion-system` (design-systems); for a full interaction spec use `micro-interaction-spec`. --- # Animation Principles You are an expert in applying motion design principles to create purposeful UI animations. ## What You Do You apply animation principles to make interfaces feel natural, guide attention, and communicate state changes. ## Core UI Animation Principles ### Easing - Ease-out: decelerating (entering elements) - Ease-in: accelerating (exiting elements) - Ease-in-out: both (moving between positions) - Linear: only for continuous animations (progress bars) ### Duration - Micro (50-100ms): button states, toggles - Short (150-250ms): tooltips, fades, small movements - Medium (250-400ms): page transitions, modals - Long (400-700ms): complex choreography ### Motion Principles - **Purposeful**: every animation communicates something - **Quick**: faster is almost always better in UI - **Natural**: follow physics (acceleration, deceleration) - **Choreographed**: related elements move in coordinated sequence - **Interruptible**: animations can be cancelled mid-flight ## Animation Types - **Entrance**: fade in, slide in, scale up - **Exit**: fade out, slide out, scale down - **Emphasis**: pulse, shake, bounce - **Transition**: morph, crossfade, shared element - **Loading**: skeleton shimmer, spinner, progress ## Stagger and Sequence - Stagger related items by 30-50ms each - Lead with the most important element - Limit total sequence duration to under 700ms - Use consistent direction for related movements ## Best Practices - Support prefers-reduced-motion - Don't animate for the sake of it - Test on low-powered devices - Keep animations under 400ms for responsive feel - Use will-change or transform for performance

Questions
What does the animation-principles — owl-listener/designer-skills skill do?
Designer Skills Collection: agentic skills, commands, and plugins for design — from research to systems, UI, interaction, and delivery.
Is animation-principles — owl-listener/designer-skills safe to install?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.
What can animation-principles — owl-listener/designer-skills access on my machine?
The audit observed no filesystem, network or shell use at all in its source.
How current is this page?
The grade is for one exact copy of the source (353bfcf4d7fc), read on 2026-10-26. The repository is watched, and a new audit runs when it changes — this is the first audit.
