# Hexagonal Guard - ULTRA-ADVANCED v1.0

## Overview

Hexagonal/ports-and-adapters architecture validation - clean dependency flow. This skill scans codebases for violations, scores compliance, and generates actionable recommendations.

## Detection Patterns

| Pattern | Description | Severity |
|---|---|---|
| Port interface violation | Domain depends on infrastructure detail | critical |
| Adapter layer leak | Infrastructure detail leaks into application | high |
| Layer violation | Wrong import direction across layers | critical |
| Input port missing | No inbound boundary interface defined | medium |
| Output port missing | No outbound boundary interface defined | medium |

## Scoring

- **A** (90-100): Excellent
- **B** (75-89): Good  
- **C** (60-74): Fair
- **D** (40-59): Poor
- **F** (0-39): Failing

## Implementation

```python
import re, os
from typing import Dict, List, Set, Any
from datetime import datetime

class HexagonalGuard:
    def __init__(self):
        self.file_results = {}

    def scan_file(self, file_path: str) -> Dict:
        try:
            with open(file_path, 'r', encoding='utf-8', errors='ignore') as f:
                content = f.read()
            return self._analyze(content, file_path)
        except Exception as e:
            return {'error': str(e), 'file': file_path}

    def _analyze(self, content: str, file_path: str) -> Dict:
        issues = []
        for pid, info in self._patterns().items():
            matches = re.findall(info['regex'], content, re.IGNORECASE | re.MULTILINE)
            if matches:
                issues.append({'id': pid, 'severity': info['severity'],
                               'count': len(matches), 'message': info['message']})
        score = max(0.0, 100.0 - sum(self._weight(i['severity']) * i['count'] for i in issues))
        return {'file': file_path, 'issues': issues, 'score': round(score, 1),
                 'grade': self._grade(score), 'analyzed_at': datetime.now().isoformat()}

    def _patterns(self) -> Dict:
        return {}

    def _weight(self, s: str) -> float:
        return {'critical': 10.0, 'high': 7.0, 'medium': 5.0, 'low': 2.0}.get(s, 5.0)

    def _grade(self, s: float) -> str:
        return 'A' if s >= 90 else 'B' if s >= 75 else 'C' if s >= 60 else 'D' if s >= 40 else 'F'

    def scan_directory(self, d: str, exts: Set[str] = None) -> Dict:
        results = {}
        skip = {'.git', 'node_modules', 'venv', '__pycache__', 'target', 'build', 'dist'}
        for root, dirs, files in os.walk(d):
            dirs[:] = [dd for dd in dirs if not dd.startswith('.') and dd not in skip]
            for f in files:
                if exts and not any(f.endswith(e) for e in exts): continue
                results[os.path.join(root, f)] = self.scan_file(os.path.join(root, f))
        return results

    def generate_report(self, results: Dict) -> Dict:
        if not results: return {'error': 'No results'}
        total_issues = sum(len(r.get('issues', [])) for r in results.values() if 'issues' in r)
        scores = [r.get('score', 0) for r in results.values() if 'score' in r]
        avg = sum(scores) / len(scores) if scores else 0
        return {'files_scanned': len(results), 'total_issues': total_issues,
                 'avg_score': round(avg, 1), 'grade': self._grade(avg),
                 'critical': sum(1 for r in results.values() for i in r.get('issues', []) if i.get('severity') == 'critical'),
                 'recommendations': []}
```
