Use this skill when designing, reviewing, or refactoring software architecture following Robert C. Martin's (Uncle Bob) Clean Architecture principles. Triggers on project structure decisions, layer design, dependency management, use case modeling, boundary crossing patterns, component organization, and separating business rules from frameworks. Covers the Dependency Rule, concentric layers, component cohesion/coupling, and boundary patterns.
Use this skill when reviewing, writing, or refactoring code for cleanliness and maintainability following Robert C. Martin's (Uncle Bob) Clean Code principles. Triggers on code review, refactoring, naming improvements, function decomposition, applying SOLID principles, writing clean tests with TDD, identifying code smells, or improving error handling. Covers Clean Code, SOLID, and test-driven development.
Use this skill when refactoring code to improve readability, reduce duplication, or simplify complex logic. Triggers on extract method, inline variable, replace conditional with polymorphism, introduce parameter object, decompose conditional, replace magic numbers, pull up/push down method, and any task requiring systematic code transformation without changing behavior.
Use when you need to review, improve, or refactor Java code for type design quality — including establishing clear type hierarchies, applying consistent naming conventions, eliminating primitive obsession with domain-specific value objects, leveraging generic type parameters, creating type-safe wrappers, designing fluent interfaces, ensuring precision-appropriate numeric types (BigDecimal for financial calculations), and improving type contrast through interfaces and method signature alignment.

Perform bulk code refactoring operations like renaming variables/functions across files, replacing patterns, and updating API calls. Use when users request renaming identifiers, replacing deprecated code patterns, updating method calls, or making consistent changes across multiple locations.
Apply design principles to create intuitive and robust library interfaces.
Code refactoring best practices based on Martin Fowler's catalog and Clean Code principles (formerly refactoring). This skill should be used when refactoring existing code, improving code structure, reducing complexity, eliminating code smells, or reviewing code for maintainability. Triggers on tasks involving extract method, rename, decompose conditional, reduce coupling, or improve readability.
Use when Code implementation and refactoring, architecturing or designing systems, process and workflow improvements, error handling and validation. Provide tehniquest to avoid over-engineering and apply iterative improvements.
Detect and simplify overly complex code. Apply KISS principle - less is more.
SOLID, DRY, KISS, and clean code principles for TypeScript applications. Use when designing scalable architecture, writing maintainable code, or reviewing code quality.
Refactor legacy codebases, migrate outdated frameworks, and implement gradual modernization. Handles technical debt, dependency updates, and backward compatibility. Use PROACTIVELY for legacy system updates, framework migrations, or technical debt reduction.
Opinionated constraints for writing maintainable, testable code. Apply MTE principles, avoid over-engineering, guide refactoring, and provide code review checklists. Use when users write code, refactor, or need code review. Triggers on keywords like "code quality", "refactor", "review", "MTE", "代码质量", "重构", "审查".
