Skill UI

This skill covers core principles for building multiplayer games, including architecture selection (dedicated server, P2P), synchronization strategies (state vs input), network optimization techniques, security measures like server authority and anti-cheat, and matchmaking considerations. It helps developers design robust, secure, and performant online experiences.

A comprehensive guide detailing the implementation of the Neo-Brutalist design aesthetic. It specifies core principles, including hard drop shadows, thick black outlines, and high-contrast flat colors. Includes detailed, platform-specific code examples for Web (CSS), SwiftUI, and Flutter, helping developers achieve a playful yet structured, high-impact UI look.

Master Node.js development principles for 2025, covering framework selection, architecture design, async patterns, validation, and security. Focuses on decision-making logic rather than code memorization to help build scalable and secure applications effectively.

Maps customer objections and addresses them with evidence and choice-preserving language when a funnel, sales page, or pitch encounters recurring hesitation. Uses psychological principles like inoculation and reactance avoidance to neutralize doubts without triggering defensiveness.

Engine selection and platform-specific principles for PC and console games. Covers Unity, Godot and Unreal comparison, Steam and console certification features, controller action mapping, haptics, and profiling-driven performance optimization.

Learn performance profiling principles: measurement, analysis, and optimization. Covers Core Web Vitals, profiling workflows, bundle analysis, runtime profiling, common bottlenecks, quick wins, and anti-patterns. Includes a Lighthouse audit script for automated checks.

This skill enables creating, editing, and analyzing PowerPoint (.pptx) files. Since .pptx is a ZIP archive with XML, you can extract text, access raw XML for comments, and analyze design elements. It covers creating presentations from scratch using HTML workflows and applying design principles.

A comprehensive guide to integrating privacy protections into software architecture from the ground up. This skill ensures compliance with major global regulations like GDPR, CCPA, and LGPD by implementing core principles such as data minimization, purpose limitation, and default privacy settings. Essential for developers building any application that handles personal user data.

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 comprehensive guide covers the principles and implementation steps for building Progressive Web Apps (PWAs). Learn to integrate essential components like Web App Manifests and Service Workers to ensure your web application offers a reliable, fast, and truly offline-capable experience, mimicking the feel of a native mobile app. Ideal for enhancing web resilience and installability.

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.
