code-quality

Apply all SOLID principles systematically using solid-principles, interface-design, and function-design skills.

Full quality assessment combining code-complexity-analysis, naming-conventions, and error-handling-patterns.

Safe refactoring combining refactoring-catalog and dependency-injection patterns.

Comprehensive code review combining clean-code-review and code-smell-detector.

Systematic code review checklist for readability, maintainability, and correctness. Use when reviewing pull requests or assessing existing code.

Measuring and reducing cyclomatic complexity and cognitive complexity to improve maintainability.

Identify code smells like long methods, duplication, low cohesion, and high coupling. Use when assessing code health.

Designing loosely coupled code through dependency injection, reducing testability barriers and hidden dependencies.

Strategies for handling errors: exceptions, error types, recovery strategies, and error propagation.

Designing pure functions with single purpose, minimal parameters, clear side effects, and high cohesion.

Designing minimal, cohesive, role-based interfaces that respect Interface Segregation Principle.

Choosing meaningful, pronounceable names that reveal intent for functions, variables, classes, and modules.

Proven refactoring patterns (Extract Method, Replace Temp, Introduce Parameter Object) to improve code structure safely. Use when improving existing code while keeping behavior unchanged.

SOLID principles (Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion) for object-oriented design.
