Skill UI

This comprehensive guide outlines world-class product design principles, mimicking Apple's standard. It covers building robust design systems, defining essential design tokens (color, typography, spacing, motion), structuring UI components (atoms to organisms), optimizing UX flows, and designing engaging onboarding experiences. Ideal for product designers and PMs needing to establish a cohesive, scalable visual language and improve overall user experience.

This skill covers principles for identifying tasks suited to LLM processing, designing effective project architectures, and iterating rapidly using agent-assisted development. It applies to batch pipelines, multi-agent systems, and interactive applications. Key concepts include task-model fit recognition, manual prototyping, pipeline architecture, file system state management, and structured output design for reliable parsing.

A comprehensive style guide and implementation toolkit for achieving authentic vintage aesthetics, inspired by 60s-80s retro design. It covers core principles like warm, muted color palettes, subtle noise textures, and classic typography pairings. Provides detailed code examples for Web (CSS), iOS (SwiftUI), and Android (Flutter) to recreate the analog, nostalgic feel in modern applications.

A comprehensive style guide and implementation reference for the Retro Futurism aesthetic. Perfect for designing interfaces that evoke the 1950s and 1960s space age, atompunk, or mid-century modern vibes. It outlines core principles, color palettes, typography, and provides cross-platform code examples (CSS, SwiftUI, Flutter, React Native) to achieve sleek, aerodynamic, chrome finishes.

This specialized skill reviews user interface animations, motion patterns, and interactive code (CSS, Framer Motion, etc.) against a strict, high-craft standard. It evaluates not only functionality but also performance, accessibility, physical correctness, and adherence to motion design principles. Use it when reviewing diffs related to transitions, keyframes, or gestures to ensure the motion feels right, not just that it runs.

Design, optimize, and test pricing strategies for SaaS products using data-driven frameworks, competitive analysis, and psychological pricing principles. Covers value metrics, Van Westendorp analysis, tier design, pricing experiments, and red flags.

A comprehensive guide for designing futuristic, tactical Heads-Up Displays (HUDs) and user interfaces. This skill provides core principles, visual DNA, and ready-to-implement code snippets for Web (CSS/SVG), App (SwiftUI), and Mobile (Flutter) platforms. Perfect for creating high-tech, sci-fi, or military-themed dashboards, featuring circular radars, minimalist strokes, and technical monospace typography.

This skill designs email nurture sequences and multi-touch communication flows using psychological principles like curiosity loops, reciprocity, and commitment. It helps create a step-by-step persuasion arc where each touchpoint prepares the next, avoiding repetitive appeals. Ideal for sales, onboarding, and marketing campaigns requiring ethical persuasion and relationship building.

Identifies error-prone APIs, dangerous configurations, and footgun designs that enable security mistakes. Evaluates whether interfaces are resistant to developer misuse and promotes secure-by-default principles. Helps review API designs, configuration schemas, and cryptographic library ergonomics to prevent vulnerabilities caused by human error or poor design choices.

This guide details the principles and implementation techniques for Skeuomorphism—the design style that makes digital interfaces resemble real-world physical objects. It covers core principles like realistic textures (wood, leather), physical lighting, depth, and real-world metaphors. Provides detailed code examples for Web (CSS), iOS (SwiftUI), and Android (Flutter) to achieve highly realistic, tactile UI elements.

A comprehensive guide for implementing soft pastel, low-contrast aesthetics across web, iOS (SwiftUI), and Flutter applications. Details include desaturated color palettes (mint, blush, lavender), rounded corner principles, airy spacing techniques, and specific CSS/SwiftUI code examples for achieving a calming, gentle user interface suitable for lifestyle or baby-related branding.

This skill provides guidance for quality-focused software development and architecture based on Clean Architecture and Domain Driven Design principles. It covers code style rules, best practices like library-first approach, naming conventions, separation of concerns, and avoiding anti-patterns to ensure maintainable and scalable code.
