Skill UI

This expert analyzes and refactors existing codebases to enhance quality, maintainability, and performance. It specializes in applying clean code principles, SOLID design patterns, and modern software engineering best practices. Use it to clean up technical debt, simplify complex modules, or prepare a codebase for new feature development.

A comprehensive guide derived from C++ Core Guidelines, enforcing modern, safe, and idiomatic practices for C++17, C++20, and C++23. It emphasizes crucial principles like RAII, type safety, immutability, and proper resource ownership using smart pointers. Use this when writing new features, reviewing existing code, or making architectural decisions to ensure code quality and consistency.

This skill acts as an expert resource for modern .NET development using C#. It guides the creation of enterprise-grade, high-performance applications by leveraging advanced C# features (like records, pattern matching), strictly adhering to SOLID principles, optimizing memory usage, and implementing comprehensive unit tests. Ideal for complex backend services and architecture tasks.

Provides a practical checklist and principles for designing database schemas, indexing strategies, query optimization, and migration planning for both SQL and NoSQL systems, plus guidance on spotting and fixing N+1 issues and denormalization trade-offs.

This skill teaches the critical principles and decision-making processes for safe production releases. It covers platform selection (e.g., Kubernetes, Vercel), mandatory pre-deployment verification (Code Quality, Environment), structured workflows (Prepare, Backup, Deploy, Verify), and advanced strategies like Blue-Green and Canary deployments. Focuses on thinking through risk mitigation, not just executing scripts.

This skill guides the planning and execution of complex business domains using Domain-Driven Design (DDD) principles. It helps developers move from strategic modeling (defining subdomains and bounded contexts) to tactical implementation patterns like CQRS, Event Sourcing, and Saga orchestration. Use it when dealing with complex, high-variability business rules and needing explicit architectural boundaries.

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 practical, jargon-free guide to applying functional programming principles using the fp-ts library in TypeScript. It teaches essential patterns like `pipe`, `Option`, `Either`, and `flatMap` to handle null checks, errors, and complex data transformations in a clean, maintainable, and robustly functional way. Ideal for developers looking to refactor imperative code.

A comprehensive guide covering core principles for game art production. It details art style selection (Pixel Art, PBR 3D, etc.), structured 2D and 3D asset pipelines, color theory, animation guidelines (including the 12 principles), and professional asset organization standards. Ideal for artists and designers managing the entire game art lifecycle.

A comprehensive guide covering the core principles of immersive game audio. Learn how to structure audio categories (SFX, Music, Ambient), implement adaptive music systems, master 3D spatialization, and apply professional mixing techniques (e.g., ducking, hierarchy) to elevate the emotional impact and technical quality of your game's soundscape. Essential for sound designers and game developers.

A comprehensive guide covering the fundamental principles of interactive entertainment design. This resource details core loop creation, structuring a Game Design Document (GDD), analyzing player psychology (motivation, reward schedules), balancing difficulty (flow state), and designing effective progression systems. It is essential for game developers, product managers, and creative designers planning engaging user experiences.

This orchestrator skill provides comprehensive core principles for game development, covering topics like the Game Loop, design patterns (State Machine, ECS), performance budgeting, and input abstraction. It guides users by routing them to specialized sub-skills based on required platforms (Web, Mobile, PC), dimensions (2D, 3D), and specialty areas (AI, Networking, Art). Ideal for structuring complex game projects from concept to implementation.
