テスト駆動開発（TDD）ワークフローを実行するスキル。 使用タイミング: (1) 新機能の実装開始時 (2) バグ修正時 (3) リファクタリング前 (4) 「テストから書いて」と言われた時 (5) 品質重視の実装が必要な時。 トリガー例: 「TDDで実装して」「テスト駆動で」「テストから書いて」 「RED-GREEN-REFACTORで」「UserServiceのテストを書いて」
Expert in improving code structure without changing behavior. Specializes in Design Patterns, SOLID principles, and Anti-Corruption Layers.
Modular Code Organization
Language-agnostic guidance for selecting and applying Gang of Four (GoF) design patterns to recurring object-oriented design problems. Use when deciding among design alternatives, evaluating applicability and tradeoffs, or refactoring rigid/conditional-heavy designs toward better extensibility and lower coupling. Do not use for trivial bug fixes, framework/tool setup, or tasks with no architectural decision. Any TypeScript examples are illustrative only and must be translated to the project's language and constraints.
Improve code readability without altering functionality using idiomatic best practices
Run a multi-agent review of changed files for reuse, quality, efficiency, and clarity issues followed by automated fixes. Use when the user asks to "simplify code", "review changed code", "check for code reuse", "review code quality", "review efficiency", "simplify changes", "clean up code", "refactor changes", or "run simplify".
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.
Follow this sub-process for code optimization — handle tasks where 'behavior remains unchanged but structure changes' (structure / performance / readability). Shift single-module internal optimization from 'AI random refactoring' to 'first scan to generate a checklist, confirm each item with the user, execute step by step according to the method library, and obtain manual approval for each step'. Trigger scenarios: When the user mentions phrases like 'optimize / refactor / rewrite / split / poor performance / too long code' without any accompanying behavior changes. Do not handle new requirements (route to feature), bugs (route to issue), or cross-module architecture restructuring (route to architecture + decisions).
Use when writing, fixing, or editing TypeScript with duplicated logic, magic values, unclear one-liners, mixed responsibilities, clutter, arbitrary code, or inconsistent abstraction levels.
Guide for writing, refactoring, and testing MoonBit projects. Use when working in MoonBit modules or packages, organizing MoonBit files, using moon tooling (build/check/run/test/doc/ide etc.), or following MoonBit-specific layout, documentation, and testing conventions.
