Skill UI

A specialist skill for building robust, scalable, and high-performance React applications. Expertise covers modern patterns including React 19, Server Components (RSC), Next.js App Router, and advanced state management (Redux/Zustand). Ideal for implementing complex features, optimizing rendering, and adhering to strict TypeScript/accessibility standards.

This skill provides production-ready architectural patterns for developing mobile applications using React Native and Expo. It covers complex topics including state management, advanced navigation patterns, integrating native modules, and implementing robust offline-first functionalities. Ideal for starting new projects or optimizing existing mobile codebases to ensure scalable and performant results.

Expert in writing, reviewing, and debugging idiomatic Rust code. This skill covers deep systems programming concepts, including mastering ownership, lifetimes, and borrowing patterns for guaranteed memory safety. Specializes in building high-performance, concurrent async applications using Tokio, and designing robust APIs using advanced trait hierarchies. Ideal for projects requiring zero-cost abstractions and maximum reliability.

This guide provides expert patterns for building robust and scalable applications on the Salesforce platform. It covers modern UI development using Lightning Web Components (LWC) with reactive data services, and teaches advanced Apex implementation. Key patterns include utilizing handler classes for bulkified triggers to prevent recursion and ensuring separation of concerns, crucial for high-performance, maintainable code.

This skill provides comprehensive patterns and best practices for implementing efficient similarity search mechanisms using vector databases. It is essential for building advanced AI systems such as semantic search engines, implementing Retrieval-Augmented Generation (RAG), and developing recommendation systems. Use this when optimizing retrieval performance or scaling to massive volumes of vectors.

This skill provides systematic patterns and best practices for transforming slow database queries into lightning-fast operations. It covers advanced topics such as proper indexing strategies, detailed query plan analysis (EXPLAIN), resolving common issues like N+1 problems, and designing highly performant database schemas. Use this when debugging performance bottlenecks, improving application response times, or ensuring scalability for growing datasets.

This skill facilitates systematic threat identification by applying the STRIDE methodology (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege). It is crucial for conducting comprehensive security analyses, performing threat modeling sessions on new or existing system architectures, and creating robust security documentation. Use it when reviewing design decisions, preparing for compliance audits, or training teams on advanced threat identification techniques.
