Problem

No detection of:

  • High cyclomatic complexity
  • Code duplication (beyond basic patterns)
  • Long methods/classes
  • God objects

Developer Pain Points

  • Code quality degrades over time
  • No automated refactoring suggestions
  • Manual code reviews catch issues late
  • No visibility into technical debt

Proposed Solution

Code Quality Analyzer with:

  1. Calculate complexity metrics (McCabe, Halstead)
  2. AST-based duplication detection
  3. Identify refactoring candidates
  4. Suggest design patterns

Features

  • Cyclomatic complexity calculation
  • Code duplication detection (AST comparison)
  • Long method detection (>50 lines)
  • God object detection (>10 methods)
  • Design pattern suggestions

MCP Tools

  • quality-analyze: Analyze code quality
  • quality-complexity: Calculate complexity
  • quality-duplicates: Find duplicated code
  • quality-refactor: Suggest refactorings

Priority

    Implemented code quality & smell detection service with 4 MCP tools:

    • quality-analyze: Comprehensive quality analysis with smell detection
    • quality-complexity: Calculate cyclomatic and cognitive complexity
    • quality-duplicates: Find duplicated code blocks
    • quality-refactor: Generate prioritized refactoring suggestions

    Features:

    • 20+ code smell types (long-method, god-object, high-complexity, etc.)
    • Configurable quality thresholds
    • Quality scoring (0-100) and grading (A-F)
    • Code duplication detection with similarity scoring
