SvelteKit is the official full-stack framework built on Svelte, enabling developers to build fast, modern, and highly performant web applications. It provides comprehensive features including file-based routing, Server-Side Rendering (SSR), Static Site Generation (SSG), API routes, and progressive form actions, all while maintaining Svelte's zero runtime overhead. Use this skill when building complex, data-driven web platforms where performance and developer experience are paramount.

Learn how to add Adaptive Card response templates to MCP-based API plugins. This guide details static, dynamic, and combined templates, enabling developers to enhance data presentation and ensure a visually rich, structured user experience within Microsoft 365 Copilot.

This module provides structured implementations of critical reliability patterns (Circuit Breaker, Graceful Degradation, Idempotency) for integrating with the Claude API. It helps developers build resilient, production-grade applications that can handle transient failures, rate limits, and service outages without failing completely, significantly enhancing system stability and user experience.

A comprehensive checklist designed to ensure Claude-powered applications are robust, secure, and production-ready before going live. It guides developers through critical areas, including robust error handling, API security best practices, cost control mechanisms, real-time monitoring setup, and performance optimization, ensuring a stable user experience.

A comprehensive directive for elite frontend developers, focusing on creating high-fidelity, award-winning web experiences. It mandates advanced techniques including GSAP motion triggers, mathematically flawless bento grids, and strict adherence to AIDA structure. This skill is crucial for building visually stunning, deeply interactive, and professional product or portfolio websites, moving beyond standard template limitations.

This comprehensive checklist ensures that your Lucidchart integration is robust and resilient for production use. It covers critical areas such as OAuth2 token lifecycle management, handling document-level collaboration locks, managing rate limits, and ensuring correct API version pinning. By following these steps, developers can mitigate risks associated with concurrent edits, large diagram exports, and schema drift, guaranteeing a stable user experience.

This guide helps developers choose the optimal architecture pattern for building on Shopify. It compares four validated variants: Embedded Remix App (for admin tools), Headless Storefront (for custom e-commerce experiences using Hydrogen), Backend Integration (for system syncing like ERP), and Theme App Extension (for storefront widgets). Use this resource when starting a new Shopify project to determine the correct development path and technology stack.

These extensions enable developers to customize the Shopify checkout experience using sandboxed, React-like components. They serve as the modern replacement for the deprecated checkout.liquid, allowing deep integration into the purchase flow. Use cases include adding custom data fields (metafields), rendering dynamic promotional banners, and reading real-time checkout state information.

This guide details how to build modern, custom headless storefronts using Shopify's Storefront API and Cart API. It covers key functionalities like product querying, cart management (adding/updating lines), and initiating the checkout flow. Designed for developers building client-facing e-commerce experiences, it emphasizes the use of public access tokens for decoupled, highly customizable online stores.

This skill guides developers through advanced techniques to optimize Shopify store performance and improve Core Web Vitals (LCP, CLS, INP). It covers fixing lazy-loaded hero images, migrating to the modern `image_url` filter for responsive images, profiling slow Liquid renders, and optimizing font delivery, ensuring a fast and professional e-commerce experience.

This skill provides the production-grade architectural blueprint for developing browser-based Integrated Development Environments (IDEs) and interactive playgrounds powered by WebContainers. It is essential for developers who are integrating the WebContainers API or utilizing the StackBlitz SDK to create robust, cloud-based development experiences.

A comprehensive guide to implementing the iconic Cyberpunk aesthetic across multiple platforms (Web, iOS, Android, Flutter). This guide details core principles like Neon-on-Black color schemes, sharply angled geometries (using clip-path or custom clippers), and glitch effects. It is ideal for developers needing to create high-tech, dystopian, or hacking interface experiences.
