Overview
Refactoring Agent detects code smells, suggests improvements, and executes safe multi-file refactoring operations. It understands your codebase holistically, ensuring that changes in one file are consistently propagated across all dependent files.
Key Features
- Code Smell Detection: Identifies long methods, deep nesting, god classes, feature envy, and other common anti-patterns. Prioritizes findings by severity and impact.
- Pattern-Aware Transforms: Recognizes opportunities to apply Extract Method, Strategy Pattern, Builder Pattern, and other established refactoring techniques.
- Safe Multi-File Operations: When renaming a function or moving a module, all references, imports, and tests are updated simultaneously.
- Incremental Refactoring: For large-scale changes, breaks work into small, reviewable steps that each maintain a passing test suite.
How It Works
The agent builds an abstract syntax tree of your codebase to understand relationships between modules, classes, and functions. It then applies transformation rules while preserving behavior, verified through your existing test suite.
Supported Languages
Primary support for TypeScript, JavaScript, Python, and Rust. Basic refactoring support for Go, Java, and C#. Language-specific idioms are respected in all transformations.
关于此技能
概述
重构代理检测代码异味、建议改进，并执行安全的多文件重构操作。它从整体上理解你的代码库，确保一个文件中的变更在所有依赖文件中一致传播。
核心功能
- 代码异味检测：识别过长方法、深层嵌套、上帝类、特性依恋等常见反模式，按严重程度和影响优先排序。
- 模式感知变换：识别应用提取方法、策略模式、建造者模式等成熟重构技术的机会。
- 安全的多文件操作：重命名函数或移动模块时，所有引用、导入和测试同步更新。
- 增量重构：对于大规模变更，将工作拆分为小的、可审查的步骤，每一步都保持测试套件通过。
工作原理
代理构建代码库的抽象语法树，理解模块、类和函数之间的关系。然后应用变换规则，同时通过现有测试套件验证行为的保持。
支持的语言
主要支持 TypeScript、JavaScript、Python 和 Rust。对 Go、Java 和 C# 提供基础重构支持。所有变换都尊重语言特定的惯用法。
Use Cases / 使用场景
- Extract repeated logic into reusable functions or modules
- Convert callback-based code to async/await patterns
- Identify and eliminate dead code paths
- Apply design patterns to improve code structure
- Rename symbols consistently across an entire codebase
- 将重复逻辑提取为可复用的函数或模块
- 将回调式代码转换为 async/await 模式
- 识别并消除无用代码路径
- 应用设计模式改善代码结构
- 在整个代码库中一致地重命名符号
