Skill UI

Master proven backend architecture patterns including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design to build maintainable, testable, and scalable systems. This skill helps in designing new backend systems, refactoring monolithic applications, and establishing architecture standards for your team. It is suitable for migrating from tightly coupled to loosely coupled architectures and planning microservices decomposition.

Designs data models, API contracts, file structures, and architectural patterns for software systems. Produces structured blueprints with ADR summaries, security notes, and migration strategies to guide implementation and code review handoffs.

Master secure authentication and authorization implementation using industry-standard patterns. Covers user login systems, REST/GraphQL API security, OAuth2, SSO, session management, and RBAC design. Includes guidance on token lifecycle, secrets storage, and threat modeling to protect resource access boundaries effectively.

Design patterns for building autonomous coding agents, covering tool and function calling APIs, permission and approval systems, browser automation, and human-in-the-loop workflows inspired by Cline and OpenAI Codex.

Expert patterns for building Azure Functions: isolated worker model, Durable Functions orchestration, cold start optimization, and production-ready serverless design across .NET, Python, and Node.js.

This skill provides expert guidance on designing scalable backend systems, APIs, and microservices. It covers service boundaries, API contracts, resilience patterns, event-driven architecture, security, and observability. Ideal for planning robust, maintainable infrastructure from day one.

This skill covers backend architecture patterns, API design, and database optimization specifically for Node.js, Express, and Next.js. It provides server-side best practices for building scalable applications. Use this for designing robust backend systems and optimizing performance in modern web development environments.

Patterns and best practices for ClickHouse analytics, including table design, query optimization, aggregations, materialized views, and bulk data ingestion for high-performance OLAP workloads.

This skill provides universal coding standards, best practices, and design patterns for TypeScript, JavaScript, React, and Node.js development projects. It ensures consistency and quality across codebases while referencing detailed guides for execution.

This skill provides a core component library and design system patterns for building consistent user interfaces. It emphasizes using design tokens for spacing, color, and typography instead of hard-coded values. Includes patterns for layout, forms, and interactive elements like buttons and inputs, ensuring maintainable and scalable UI development.

This skill specializes in code refactoring using clean code principles and SOLID design patterns. It helps analyze and refactor code to improve quality, maintainability, and performance. Ideal for cleaning large codebases, removing duplication, and preparing for new features while aligning with modern software engineering best practices.

This skill guides developers in building flexible and maintainable React components by applying composition patterns. It helps avoid boolean prop proliferation through compound components, state lifting, and internal composition. Suitable for refactoring, library building, and API design to improve code scalability for humans and AI agents.
