Skill UI

A maximum-level product invention and design skill that fuses product thinking, design systems, UI engineering, cognitive psychology and storytelling to craft Apple-grade product experiences and innovation.

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.

Master advanced prompt engineering techniques to maximize LLM performance, reliability, and controllability. Learn core capabilities including few-shot learning, chain-of-thought prompting, prompt optimization, template systems, and system prompt design. This skill helps design complex prompts for production applications, optimize consistency, and implement structured reasoning patterns for specialized AI assistants.

Build accessible, production-grade design systems with Radix UI headless primitives. Covers theming strategies, compound component patterns, and WCAG-compliant React component libraries with full styling control.

Expert in building Retrieval-Augmented Generation systems for LLM applications. Masters embedding models, vector databases, chunking strategies, and retrieval optimization. Capable of designing retrieval pipelines, implementing hybrid search, and optimizing context windows to ensure high-quality generation from retrieved documents.

This comprehensive workflow guides the end-to-end implementation of Retrieval-Augmented Generation (RAG) systems. It covers critical stages, including selecting optimal embedding models, setting up vector databases, designing chunking strategies, implementing hybrid retrieval, integrating Large Language Models (LLMs), and performing rigorous evaluation. Use this when building knowledge-grounded AI applications or advanced semantic search systems.

Generate production-quality React components and UIs using the specialized Rayden UI component library and Tailwind CSS. This skill ensures that all generated code strictly adheres to a defined design system, including correct component usage, design tokens, prop validation, and established layout patterns. Ideal for scaffolding complex pages like dashboards, login forms, and data tables while maintaining premium aesthetics and consistency.

This skill allows users to build and maintain complex UI components and full screens directly within Figma using the Figma MCP. It rigorously enforces a defined design system (like Rayna UI) by validating design tokens, applying craft rules, detecting anti-patterns, and ensuring visual consistency. Ideal for creating new components, composing entire dashboards or landing pages, or auditing existing files for compliance.

Reference document for monopoly scale-benchmarks. Provides quick formulas for converting DAU to RPS, storage and bandwidth estimation, known scale limits of common technologies (databases, queues, caching), capacity planning by user scale (1K to 10M DAU), SLO targets, and latency budget guidelines. Useful for system design, capacity planning, and architecture decisions.

This specialized skill guides users through a structured, forensic investigation process when facing sudden, significant drops in organic traffic or search rankings. It is designed for incident scenarios—such as suspected penalties, Core Updates, major technical regressions, or unexplained traffic crashes—providing a systematic approach to triage, root-cause analysis, and developing a prioritized recovery plan.

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.

A comprehensive guide for implementing user interfaces that mimic spatial computing devices (like Apple Vision Pro). It focuses on creating digital elements with a sense of depth (Z-Space), utilizing glass-like materials via backdrop blur, and designing gaze-aware interactions, making digital information feel physically anchored in the real environment.
