Master modern API documentation using OpenAPI 3.1, AsyncAPI, and advanced AI tools. This skill facilitates the creation of world-class, interactive developer portals, robust SDK generation, and comprehensive API specifications. It ensures documentation is always accurate, actionable, and significantly improves the overall developer experience (DX), reducing time-to-integration.

A comprehensive guide detailing best practices for creating modern, clean, and highly maintainable user interfaces using Avalonia and Zafiro.Avalonia. It emphasizes leveraging semantic containers, defining shared styles, and utilizing generic components to dramatically reduce XAML redundancy and improve code structure. Learn to adopt patterns like Behaviors over Converters, and prevent deep nesting for optimal developer experience.

This skill acts as a Developer Experience (DX) specialist, focusing on minimizing development friction and maximizing productivity. It helps optimize environment setup, automate repetitive workflows, enhance tooling, and improve project documentation. Use it when establishing new projects, refining existing development cycles, or troubleshooting workflow bottlenecks to achieve seamless and efficient development.

This skill provides guidance on implementing robust error handling strategies to build highly resilient applications. It covers advanced patterns such as circuit breakers, retries, and handling asynchronous errors, ensuring that the application fails gracefully and provides excellent debugging experiences for both developers and end-users.

A comprehensive guide detailing Apple's Human Interface Guidelines (HIG) for building adaptive and consistent user interfaces. It covers best practices for layout architecture, navigation patterns (e.g., Tab Bars, Sidebars, Split Views), and component usage across multiple platforms, including iOS, iPadOS, macOS, and visionOS. Essential for developers aiming for a native, high-quality user experience.

This comprehensive guide outlines Apple's Human Interface Guidelines (HIG) for various technologies and user flows (e.g., Siri, Apple Pay, HealthKit, ARKit, Generative AI). It teaches developers how to ensure their applications feel natively integrated, respect user privacy, and adhere to established platform patterns across iOS, macOS, and other Apple devices. Essential reading for building high-quality, compliant, and seamless user experiences.

This SDK provides Azure Functions extensions for handling Microsoft Entra ID custom authentication events within a .NET environment. Developers can intercept key stages of the authentication lifecycle, such as token issuance, attribute collection, and OTP sending. Use cases include enriching access tokens with custom claims, fetching external user data to populate profiles, and customizing the sign-up user experience.

This skill provides comprehensive principles for developing multiplayer games, covering essential topics from networking architecture (Dedicated, P2P, Host-based) to advanced synchronization techniques. It details how to handle latency via prediction, interpolation, and lag compensation, optimize bandwidth using delta compression, and implement robust security measures like server authority and anti-cheat systems. Ideal for developers building real-time online experiences.

This comprehensive checklist guides developers through the pre-release verification process for Obsidian community plugins. It covers critical technical areas such as validating manifest structure, ensuring clean production builds (e.g., removing sourcemaps), identifying potential memory leaks, and verifying cross-platform readiness, ensuring a high-quality user experience upon submission.

This skill provides comprehensive guides on implementing real-time streaming responses using OpenRouter's Server-Sent Events (SSE) capability. It covers various languages (Python, TypeScript, FastAPI, JavaScript), enabling developers to build modern, fast-feeling chat interfaces. By streaming tokens as they are generated, it significantly reduces the time-to-first-token (TTFT) and improves user experience for long completions and chat applications.

This comprehensive guide covers the full stack of Shopify development. Learn to build robust custom applications, highly customized extensions (for checkout, admin, and POS), and dynamic storefront themes. It details using GraphQL Admin API, managing webhooks, and utilizing Liquid for templating, enabling developers to integrate external services and enhance the entire merchant e-commerce experience.
