Skill UI

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.

ClickHouse database patterns for high-performance analytics, including table design, query optimization, bulk inserts, materialized views, and performance monitoring.

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.

Common AWS CDK patterns and constructs for building cloud infrastructure using TypeScript, Python, or Java. Ideal for designing reusable stacks, L3 constructs, and implementing serverless or containerized applications. Helps enforce best practices like least privilege IAM roles and proper resource tagging.

This skill provides specialized guidance and structured patterns for conducting scientific research and analysis tasks. It helps users formulate hypotheses, design experiments, analyze data, and interpret results within a scientific context. Use this when the task involves rigorous scientific methodology, literature review, or technical analysis requiring expert-level reasoning. It is not a substitute for professional validation or safety checks.

This expert AI code reviewer evaluates code across correctness, security, performance, design, and readability. It identifies bugs, vulnerabilities, and anti-patterns with actionable fix suggestions. Supports Python, JavaScript, Go, and Rust. Provides structured feedback with metrics and positive notes to improve code quality.

A skill for building UI with a core component library and design system patterns. Provides guidance on using design tokens for spacing, colors, and typography, and includes patterns for Box, HStack, VStack, Text, Button, Input, and Card components. Ideal for consistent, maintainable UI development.

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.

This guide provides best practices for building flexible, maintainable, and scalable React components. It emphasizes using composition patterns and compound components to avoid 'boolean prop proliferation,' while also detailing advanced concepts in component architecture, state management, and modern implementation techniques (including React 19 APIs). Ideal for refactoring complex systems or designing reusable component libraries.

This skill covers predictable performance degradation patterns in language models as context length increases, including lost-in-middle effects, context poisoning, and distraction. It helps diagnose agent failures and design resilient systems by understanding attention mechanics and context engineering strategies for production environments.

This skill covers building user interfaces using a core component library and design system patterns. It emphasizes using design tokens for spacing, color, and typography instead of hard-coded values. Includes components like Box, Button, Input, and layout patterns for forms and lists. Ensures consistent styling and behavior across the application.

This skill processes raw, unstructured materials (e.g., conversations, reports, controversies) into highly structured, reusable casebook entries. It focuses on identifying core facts, defining mechanism chains, and mapping responsibility links while ensuring rigorous data anonymization. It is designed for deep knowledge management and pattern recognition, helping users build a reliable, reusable knowledge base for future professional analysis, rather than generating immediate advice.
