SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps software teams automatically detect code smells and anti-patterns in code reviews, enabling early quality feedback and maintainability improvements.

Core Features & Use Cases

  • Smell detection: Analyzes code for common smells across languages, including Long Method, Duplication, and Complex Conditionals.
  • Metrics-backed insights: Reports LOC, complexity, and duplication to prioritize fixes.
  • Use Case: During a pull request, the skill analyzes touched files and returns a prioritized list of issues with actionable suggestions.

Quick Start

Review a target code file (for example, src/utils/data-transform.js) to generate a smells report and suggested refactors.

Frequently Asked Questions about detect-code-smells

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

FAQPage Schema
How do I detect code smells and anti-patterns during a code review?▼

To detect code smells during a code review, open the target source file for analysis. The tool uses AST parsing and metrics-based scoring to identify issues like Long Method and Complex Conditionals, returning a prioritized list with actionable refactoring suggestions.

What are common code smells analyzed using static analysis?▼

Common code smells analyzed using static analysis include Long Method, Duplication, and Complex Conditionals. The tool targets these anti-patterns by implementing pattern matching across multiple programming languages to improve overall code maintainability.

Can I use AST parsing to find complex conditionals across different programming languages?▼

Yes, you can use AST parsing to find complex conditionals across different programming languages. The tool analyzes opened files regardless of language, using AST parsing and pattern matching to spot anti-patterns and provide actionable feedback.

What metrics are used to prioritize code refactoring suggestions?▼

Metrics used to prioritize code refactoring suggestions include lines of code (LOC), complexity, and duplication. These metrics-backed insights help developers focus on the most critical maintainability issues found during audits.

Does static analysis for code smells work on files touched in a pull request?▼

Static analysis for code smells works effectively on files touched in a pull request. The tool analyzes the opened target files, generating a smells report with suggested refactors to provide early quality feedback.
