The Evolution of Code Analysis

Code analysis has evolved through three distinct generations:

  1. Static Analysis Era: Tools that find bugs and style issues
  2. Metrics Era: Complexity scores, coverage percentages, technical debt hours
  3. AI Context Era: Intelligent understanding of code purpose and quality

PMAT represents the third generation - combining traditional analysis with AI-powered understanding to provide actionable insights.

What Makes PMAT Different

Zero Configuration Philosophy

# Traditional tools require setup
eslint --init
sonarqube configure
pylint --generate-rcfile

# PMAT just works
pmat analyze .

Instant Results

Within seconds, PMAT provides:

  • Complete repository overview
  • Language distribution
  • Technical debt grading (A+ to F)
  • Actionable recommendations
  • MCP-ready context

Production Quality Standards

PMAT follows the Toyota Way principles:

  • Kaizen: Continuous improvement in every release
  • Genchi Genbutsu: Go and see for yourself (real code analysis)
  • Jidoka: Built-in quality at every step

Core Capabilities

1. Repository Analysis

pmat analyze /path/to/repo

Instant insights into any codebase - structure, languages, complexity, and patterns.

2. Technical Debt Grading (TDG)

pmat analyze tdg /path/to/repo

Six orthogonal metrics provide comprehensive quality scoring:

  • Structural Complexity
  • Semantic Complexity
  • Code Duplication
  • Coupling Analysis
  • Documentation Coverage
  • Consistency Patterns

3. Code Similarity Detection

pmat similarity /path/to/repo

Advanced detection of duplicates and similar code:

  • Type-1: Exact clones
  • Type-2: Renamed variables
  • Type-3: Modified logic
  • Type-4: Semantic similarity

4. MCP Integration

{
  "tool": "analyze_repository",
  "params": {
    "path": "/workspace/project"
  }
}

Native Model Context Protocol support for AI agents.

Real-World Impact

Teams using PMAT report:

  • 50% reduction in code review time
  • 80% faster onboarding for new developers
  • 90% accuracy in technical debt identification
  • 100% coverage of multi-language codebases
