Searches code by AST patterns and performs structural refactoring across files. Use when finding function calls, replacing code patterns, or refactoring syntax that regex cannot reliably match.
Write clean, readable, and maintainable code following principles from Robert C. Martin's "Clean Code" and Object Calisthenics. Use when writing, reviewing, or refactoring code to improve naming, function design, formatting, error handling, and class structure. Includes code smell detection and refactoring guidance.
Guides when to abstract vs duplicate code. Use this skill when creating shared utilities, deciding between DRY/WET approaches, or refactoring existing abstractions.
Systematically fix all failing tests after business logic changes or refactoring
Clean Code practices for TypeScript/JavaScript. Identify code smells, apply refactoring patterns, and write maintainable code. Use when reviewing code quality, refactoring messy code, or ensuring code follows best practices. Triggers on requests like "clean up this code", "refactor for readability", "identify code smells", or "make this more maintainable".
Use when the user needs code quality review, refactoring guidance, SOLID principles application, or help identifying and fixing code smells. Triggers: code smell detection, refactoring planning, naming convention review, complexity reduction, DRY analysis, error handling improvement.
Refactoring workflow — test coverage gate, DRY + SOLID analysis, SRP decomposition, pattern discovery, spec-driven user review, and execution planning
PHPUnit testing best practices and conventions guide. This skill should be used when writing, reviewing, or refactoring PHPUnit tests to ensure consistent, maintainable, and effective test suites. Triggers on tasks involving test creation, test refactoring, test configuration, code coverage, data providers, mocking, or PHPUnit XML configuration.
Analyze code for patterns, complexity, dependencies, and quality. Use when: code review, refactoring, understanding codebases.
Identify refactoring opportunities by surfacing architectural friction. Apply the deletion test, deep-modules vocabulary, and seams analysis. Each opportunity becomes its own evanflow-writing-plans cycle. Use when reviewing code for refactoring, when a file has grown too large, or when architecture concerns surface during feature work.
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
Use this skill when > Identify architectural friction and propose deepening opportunities — refactors that turn shallow modules into deep ones for better testability and AI-navigability. Use when improving architecture, finding refactoring opportunities, consolidating tightly-coupled modules, or making a codebase more testable.
