Review React 19 test quality including coverage, patterns, and React 19 API testing. Use when reviewing tests or test coverage.

This skill analyzes code for design quality improvements across 8 dimensions: Naming, Object Calisthenics, Coupling & Cohesion, Immutability, Domain Integrity, Type System, Simplicity, and Performance. Ensures rigorous, evidence-based analysis by: (1) Understanding code flow first via implementation-analysis protocol, (2) Systematically evaluating each dimension with specific criteria, (3) Providing actionable findings with file:line references. Triggers when users request: code analysis, design review, refactoring opportunities, code quality assessment, architecture evaluation.

Method implementation finder and analyzer for Pharo Smalltalk. Provides expertise in discovering implementors across class hierarchies (search_implementors), analyzing implementation patterns, learning coding idioms from existing implementations, assessing refactoring impact (counting implementors and references), finding duplicate code for consolidation, understanding abstract method implementations (subclassResponsibility), and tracing method overrides through inheritance chains. Use when analyzing method implementations across classes, learning implementation idioms, assessing refactoring risk before changes, finding duplicate implementations for consolidation, understanding how abstract methods are implemented in concrete classes, or tracing which classes override specific methods.

Implement CQRS (Command Query Responsibility Segregation) pattern for Electron services. Use when creating service methods, separating read/write operations, or implementing reactive data streams with Observable for queries and ResultAsync for commands.

This skill should be used when creating or refactoring Claude Code skills, guiding an interactive questionnaire, selecting an archetype (workflow/tool/domain), scaffolding from templates, and validating the result.
