Build Apple-inspired translucent interfaces using shared CSS settings and component patterns. The skill covers glass cards, toolbars, buttons, and modals, with light and dark modes, motion guidance, and accessibility requirements for readable text and reduced animation.
Apple Liquid Glass design system. Use when building UI with translucent, depth-aware glass morphism following Apple's design language. Provides CSS tokens, component patterns, dark/light mode, and animation specs.
Review the instructions the agent will receive before you install.
Apple-inspired translucent glass UI with depth, refraction, and ambient light response.
Import the token file in your CSS:
@import 'references/tokens.css';
All tokens are defined in references/tokens.css. Key categories:
| Category | Prefix | Example |
|---|---|---|
| Glass backgrounds | --lg-bg-* | --lg-bg-primary |
| Blur | --lg-blur-* | --lg-blur-md |
| Borders | --lg-border-* | --lg-border-color |
| Shadows | --lg-shadow-* | --lg-shadow-elevated |
| Radius | --lg-radius-* | --lg-radius-lg |
| Animation | --lg-duration-* | --lg-duration-normal |

Tokens auto-switch via prefers-color-scheme. Light mode uses white-tinted glass; dark mode uses dark-tinted glass with higher blur to maintain readability.
/* Force a mode on a subtree */
.light-glass { color-scheme: light; }
.dark-glass { color-scheme: dark; }
Use spring-based easing for physical feel:
/* Entry */
@keyframes glass-enter {
from { opacity: 0; transform: scale(0.95) translateY(8px); }
to { opacity: 1; transform: scale(1) translateY(0); }
}
.glass-animate-in {
animation: glass-enter var(--lg-duration-normal) var(--lg-easing-spring) both;
}

Adapts existing designs for phones, tablets, desktops, print, and email. Adjusts layouts, navigation, content priorities, and touch controls to suit each context, with guidance for responsive sizing and verification across devices and input methods.
Audit a website for Google AdSense application readiness or ongoing ad-serving issues. Check content, navigation, crawler access, and disclosures against official requirements, then receive evidence-based findings, specific fixes, and a complete checklist with unresolved questions clearly marked.
Routes AI development questions to focused references on agents, language model security, retrieval-augmented generation, which uses retrieved information in answers, and prompt design and evaluation. It also outlines principles for validation, safety boundaries, version control, and ongoing assessment.
Review an interface and add purposeful motion to buttons, forms, navigation, and state changes. Plan and implement animations that clarify actions and provide feedback, while checking performance and supporting users who prefer reduced motion.
Find the relevant architectural guidance for API design, security, cloud infrastructure, message queues, and caching. This skill acts as an index to specialized references and lists principles for structuring software, distributed systems, and access controls.
Improve interface layouts by reviewing spacing, alignment, content density, and visual hierarchy, the cues that show what matters most. Refine repetitive card grids and crowded sections into compositions with consistent spacing and responsive structure.
