    AI Code Refactoring: Automated Clean Code Transformations

    Paste messy code, get clean code. AI-powered refactoring that applies SOLID principles, reduces complexity, and improves readability.

    Refactoring Code Quality

    Technical Debt Accumulates Faster Than You Think

    Every shortcut, every "I'll fix it later," every copy-paste adds to your codebase's complexity. AI refactoring identifies these patterns and suggests clean transformations — extract method, rename variable, simplify conditionals — at scale.

    How It Works

    Submit a file or function. The AI analyzes cyclomatic complexity, code smells, and design pattern violations, then produces a refactored version with explanations for every change.

    import vincony
    
    client = vincony.Client(api_key="YOUR_API_KEY")
    
    messy_code = """
    def process(data):
        result = []
        for item in data:
            if item['type'] == 'A':
                if item['status'] == 'active':
                    if item['value'] > 100:
                        result.append({'name': item['name'], 'total': item['value'] * 1.1})
        return result
    """
    
    refactored = client.tools.refactor(
        code=messy_code,
        language="python",
        principles=["single_responsibility", "early_return", "descriptive_naming"],
        explain_changes=True
    )
    
    print(refactored.code)
    # def calculate_premium_totals(items: list[dict]) -> list[dict]:
    #     return [
    #         {"name": item["name"], "total": item["value"] * 1.1}
    #         for item in items
    #         if _is_active_premium(item)
    #     ]
    #
    # def _is_active_premium(item: dict) -> bool:
    #     return (item["type"] == "A" and item["status"] == "active" and item["value"] > 100)
    
    for change in refactored.changes:
        print(f"• {change.type}: {change.explanation}")

    Batch Refactoring

    Point the refactoring engine at an entire directory. It analyzes cross-file dependencies, identifies the highest-impact improvements, and produces a prioritized refactoring plan.

    # Analyze an entire project
    analysis = client.tools.refactor.analyze_project(
        files=["src/api/handlers.py", "src/api/models.py", "src/api/utils.py"],
        focus=["complexity_reduction", "duplication_removal"]
    )
    
    print(f"Total issues: {analysis.total_issues}")
    print(f"Estimated time saved: {analysis.time_saved_hours}h")
    for issue in analysis.top_issues[:5]:
        print(f"  [{issue.severity}] {issue.file}:{issue.line} — {issue.description}")

    Safety Guarantees

    Every refactoring preserves behavior. The AI generates before/after test cases to verify equivalence. Diffs are clearly highlighted so you can review every change before applying.
