Moyu
Plugin Verified ActiveAnti-over-engineering skill for AI coding agents. Teaches your AI when to stop.
To help users train their AI coding assistants to stop over-engineering, produce minimal and focused code, and avoid unnecessary complexity.
Features
- Prevents AI over-engineering
- Enforces three core rules: only change what's asked, use the simplest solution, ask when unsure
- Provides multiple skill variants (strict, lite, localized)
- Supports various AI platforms with specific installation instructions
Use Cases
- When your AI coding assistant adds unnecessary features or refactors excessively.
- To ensure AI-generated code is concise and directly addresses the user's request.
- To train AI agents on best practices for minimal and focused code changes.
- To reduce the time spent reviewing AI-generated code for unnecessary additions.
Non-Goals
- Encouraging AI to be lazy or unproductive.
- Providing a general-purpose AI debugging tool.
- Adding new features or code beyond what the user explicitly requests.
Workflow
- User installs the Moyu plugin/skill for their AI agent.
- The AI agent is prompted or detects over-engineering patterns.
- Moyu's rules are applied, guiding the AI to adhere to core principles.
- The AI produces code that is minimal, focused, and directly addresses the user's request.
- User reviews the code, which is expected to be less verbose and complex.
Practices
- Code Minimalism
- Scope Control
- Prompt Engineering
Prerequisites
- An AI coding agent compatible with the installation method (e.g., Claude Code, Cursor, VS Code with Copilot)

S'active automatiquement lorsque des patterns de sur-ingénierie sont détectés : (1) Modifier du code ou des fichiers que l'utilisateur n'a pas explicitement demandé de changer (2) Créer de nouvelles couches d'abstraction (class, interface, factory, wrapper) sans demande (3) Ajouter des commentaires, de la documentation, JSDoc ou des annotations de type sans demande (4) Introduire de nouvelles dépendances sans demande (5) Réécrire des fichiers entiers au lieu de faire des modifications minimales (6) Le diff dépasse significativement la portée de la demande de l'utilisateur (7) L'utilisateur signale "trop", "ne change pas ça", "change seulement X", "garde ça simple", "arrête" (8) Ajouter de la gestion d'erreurs, de la validation ou du code défensif pour des scénarios impossibles (9) Générer des tests, du scaffolding de configuration ou de la documentation sans demande
過剰エンジニアリングのパターンが検出された場合に自動的に発動します： (1) ユーザーが明示的に変更を求めていないコードやファイルを修正する (2) 要求されていない新しい抽象レイヤー（class、interface、factory、wrapper）を作成する (3) 要求されていないコメント、ドキュメント、JSDoc、型注釈を追加する (4) 要求されていない新しい依存パッケージを導入する (5) 最小限の編集ではなくファイル全体を書き直す (6) diff の範囲がユーザーの要求を明らかに超えている (7) ユーザーが「やりすぎ」「そこは変えないで」「Xだけ変えて」「シンプルに」「やめて」と言う (8) 起こり得ないシナリオに対するエラーハンドリング、バリデーション、防御的コードを追加する (9) 要求されていないテスト、設定のスキャフォールディング、ドキュメントを生成する
과잉 엔지니어링 패턴이 감지되면 자동으로 활성화됩니다: (1) 사용자가 명시적으로 변경을 요청하지 않은 코드나 파일을 수정하는 경우 (2) 요청되지 않은 새로운 추상화 레이어(class, interface, factory, wrapper)를 생성하는 경우 (3) 요청되지 않은 주석, 문서, JSDoc, 타입 어노테이션을 추가하는 경우 (4) 요청되지 않은 새로운 의존성을 도입하는 경우 (5) 최소한의 편집 대신 파일 전체를 다시 작성하는 경우 (6) diff 범위가 사용자의 요청을 명백히 초과하는 경우 (7) 사용자가 "너무 많아", "거기는 건드리지 마", "X만 변경해", "간단하게", "그만" 등의 신호를 보내는 경우 (8) 발생할 수 없는 시나리오에 대한 에러 처리, 유효성 검사, 방어적 코드를 추가하는 경우 (9) 요청되지 않은 테스트, 설정 스캐폴딩, 문서를 생성하는 경우
Lightweight anti-over-engineering guard. Activates when: (1) Modifying code or files the user did not explicitly ask to change (2) Creating new abstraction layers without being asked (3) Rewriting entire files instead of making minimal edits (4) Diff scope significantly exceeding the user's request (5) User signals like "too much", "only change X", "keep it simple" 轻量级反过度工程守卫。当检测到以下模式时激活： (1) 修改用户未明确要求改动的代码或文件 (2) 创建用户未要求的新抽象层 (3) 重写整个文件而非做最小编辑 (4) diff 范围明显超出用户请求 (5) 用户说"太多了"、"只改 X"、"简单点"
Strict anti-over-engineering enforcement. Activates on ANY code change to verify scope: (1) Modifying code or files the user did not explicitly ask to change (2) Creating new abstraction layers (class, interface, factory, wrapper) without being asked (3) Adding comments, documentation, JSDoc, or type annotations without being asked (4) Introducing new dependencies without being asked (5) Rewriting entire files instead of making minimal edits (6) Diff scope significantly exceeding the user's request (7) Adding error handling, validation, or defensive code for scenarios that cannot occur (8) Generating tests, configuration scaffolding, or documentation without being asked (9) Any diff exceeding 20 lines for a single-point change 严格反过度工程执行模式。任何代码变更时激活以验证范围： (1) 修改用户未明确要求改动的代码或文件 (2) 创建用户未要求的新抽象层 (3) 添加用户未要求的注释、文档、类型注解 (4) 引入用户未要求的新依赖 (5) 重写整个文件而非做最小编辑 (6) diff 范围明显超出用户请求 (7) 为不可能发生的场景添加错误处理 (8) 未被要求就生成测试、配置、文档 (9) 单点改动 diff 超过 20 行
