SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill detects structural issues like overly long functions, deep nesting, and mixed concerns in codebases, helping developers improve code readability and maintainability.

Core Features & Use Cases

  • Detect Long Functions: Finds functions exceeding 50 lines across multiple languages such as Dart, Python, Go, Rust, and web frameworks, then suggests refactoring strategies.
  • Analyze Widget Build Methods: Identifies overly lengthy build methods in Flutter or similar frameworks and recommends extracting smaller components.
  • Identify Deep Nesting and Coupling: Finds excessive nesting levels and tight dependencies, proposing early returns, modularization, and dependency injection.
  • Detect God Classes and Excessive Coupling: Flags classes with too many responsibilities or tightly coupled modules for splitting or decoupling.
  • Flag Complex Match Chains and Large Impl Blocks: Suggests extraction of functions or splitting large classes for clarity.
  • Cross-language Support: Applies analysis rules to Dart, Python, Go, Rust, and JavaScript/TypeScript, highlighting language-specific refactoring tips.

Quick Start

Detect issues in your codebase using this skill to automatically identify long functions, deep nesting, and large classes requiring refactoring, improving maintainability and clarity.

Frequently Asked Questions about spaghetti-code

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I detect and refactor long functions in my codebase?▼

To detect long functions exceeding 50 lines, this tool analyzes code structure across languages like Dart, Python, and Go, then suggests extracting smaller components and modularization strategies to improve maintainability.

What is the best way to analyze deep nesting and tight coupling in Python code?▼

Analyzing deep nesting and tight coupling involves identifying excessive nesting levels and dependencies, then proposing early returns, modularization, and dependency injection to decouple modules and enhance readability.

Can I identify God Classes and excessive coupling in Rust and Go projects?▼

Yes, you can identify God Classes and excessive coupling in Rust and Go projects by flagging classes with too many responsibilities or tightly coupled modules, recommending splitting or decoupling for clarity.

How do I analyze Flutter widget build methods for structural code issues?▼

Analyzing Flutter widget build methods identifies overly lengthy build methods and recommends extracting smaller components, ensuring high maintainability and readability through targeted refactoring guidance.

Does this structural analysis support JavaScript and TypeScript refactoring?▼

Yes, structural analysis supports JavaScript and TypeScript refactoring by applying analysis rules to detect complex match chains and large implementation blocks, highlighting language-specific refactoring tips.

What are common spaghetti code issues and when do I need structural analysis?▼

Common spaghetti code issues include mixed concerns, deep nesting, and overly long functions; you need structural analysis when code readability drops and maintainability becomes difficult across multiple programming languages.
