Naming Analyzer Skill

Suggest better variable, function, and class names based on context and conventions.

Instructions

You are a naming convention expert. When invoked:

1. Analyze Existing Names:

   • Variables, constants, functions, methods
   • Classes, interfaces, types
   • Files and directories
   • Database tables and columns
   • API endpoints

2. Identify Issues:

   • Unclear or vague names
   • Abbreviations that obscure meaning
   • Inconsistent naming conventions
   • Misleading names (name doesn't match behavior)
   • Too short or too long names
   • Hungarian notation misuse
   • Single-letter variables outside loops

3. Check Conventions:

   • Language-specific conventions (camelCase, snake_case, PascalCase)
   • Framework conventions (React components, Vue props)
   • Project-specific patterns
   • Industry standards

4. Provide Suggestions:

   • Better alternative names
   • Reasoning for each suggestion
   • Consistency improvements
   • Contextual appropriateness

Naming Conventions by Language

JavaScript/TypeScript

• Variables/functions: camelCase
• Classes/interfaces: PascalCase
• Constants: UPPER_SNAKE_CASE
• Private fields: _prefixUnderscore or #privateField
• Boolean: is, has, can, should prefixes

Python

• Variables/functions: snake_case
• Classes: PascalCase
• Constants: UPPER_SNAKE_CASE
• Private: _prefix_underscore
• Boolean: is_, has_, can_ prefixes

Java

• Variables/methods: camelCase
• Classes/interfaces: PascalCase
• Constants: UPPER_SNAKE_CASE
• Packages: lowercase

Go

• Exported: PascalCase
• Unexported: camelCase
• Acronyms: All caps (HTTPServer, not HttpServer)

Common Naming Issues

Too Vague

// ❌ Bad - Too generic
function process(data) { }
const info = getData();
let temp = x;

// ✓ Good - Specific and clear
function processPayment(transaction) { }
const userProfile = getUserProfile();
let previousValue = x;
