Skill UI

This comprehensive skill covers the full scope of Firebase services, including Authentication, Firestore, Cloud Functions, and Hosting. It goes beyond basic implementation, focusing on critical architectural principles: adopting a query-first, denormalized NoSQL mindset. Key insights include mandatory security rule design, optimal data modeling for performance, and correctly utilizing modular SDKs to build scalable and secure backends.

A comprehensive guide for designing cross-device applications across the Apple ecosystem. This skill helps developers adhere to the specific Human Interface Guidelines (HIG) for various platforms—including iOS, macOS, watchOS, tvOS, and visionOS. It emphasizes adapting design principles (e.g., touch-first vs. pointer-based vs. spatial) while maintaining brand consistency, ensuring a native and optimal user experience regardless of the operating system.

A comprehensive guide to modern utility-first CSS using Tailwind CSS v4 principles. Covers the shift to CSS-first configuration, utilizing CSS variables for design tokens, implementing advanced container queries, and mastering responsive, dark mode, and complex layout patterns (Grid/Flex). Essential for building modern, component-driven UIs efficiently.

This skill simulates a senior documentation engineer, generating highly comprehensive, evidence-based technical documentation pages. It strictly adheres to engineering best practices, including tracing actual code paths, citing every non-trivial claim with file paths and line numbers, and providing multiple required diagrams (Mermaid format). It structures content from 'Why' (First Principles) through Architecture, Data Flow, and Implementation details, suitable for deep technical deep-dives and wiki content creation.

This skill performs deep, architectural context building by conducting ultra-granular, line-by-line analysis of code. It applies advanced reasoning techniques like First Principles, 5 Whys, and 5 Hows to map system invariants, data flows, and assumptions across entire call chains (including external black-box calls). It is designed to establish a complete, stable mental model of the system's logic before any vulnerability or bug hunting begins, ensuring bottom-up understanding.

Roleplay agent that embodies Elon Musk with high-fidelity psychological and communicational modeling, ideal for first-principles reasoning, innovation brainstorming, and opinionated discussions rooted in Musk’s persona.

Simulates the persona of Geoffrey Hinton, a Turing Award winner and pioneer of deep learning. This skill adopts his first-person voice, combining deep technical knowledge (including backpropagation, deep belief networks, and Boltzmann machines) with academic rigor, epistemic humility, and characteristic British humor. It is ideal for in-depth discussions on the theoretical foundations, history, and principles of complex system learning in AI.

This skill simulates a high-powered 'Board of Advisors,' consulting multiple specialized agents (e.g., Elon Musk, Warren Buffett, Steve Jobs, Bill Gates) simultaneously. It ensures that any topic is analyzed from diverse, unique perspectives—be it first principles, economic moats, design experience, or system scalability. The system gathers these varied insights and synthesizes them into a comprehensive, actionable decision or strategic report that no single expert could produce alone. Ideal for complex product, investment, or technical strategy planning.

Provides actionable guidance and review checklists for modern clean UI/UX, emphasizing CRAP principles, task-first flows, information architecture, system feedback, consistency, and refined iconography.

A comprehensive, systematic framework for auditing and improving web UI designs and frontend code. It teaches core principles like grayscale-first design, constrained scaling (for spacing, type, and color), and establishing clear visual hierarchy. Use this guide when needing to refine an existing UI that 'looks off,' or requires professional structural and aesthetic improvements.

This skill applies principles of behavioral psychology to redesign user onboarding flows. Instead of simple feature tours, it focuses on engineering the first-use experience to achieve 'early wins,' build competence, establish ownership, and trigger habit formation. Use it when the goal is to reduce user friction, combat early drop-off, and shift the user's self-perception from an outsider to an active participant.

This skill guides the creation of highly persuasive sales pitches, investor decks, and presentations using established principles of behavioral psychology. It utilizes a 'Desire-Then-Solution Arc' structure, ensuring that the audience first connects with the problem and the aspiration (building desire) before the solution is presented, thereby maximizing buy-in and making the offer feel inevitable. Ideal for critical business communications.
