ArchitectShield is an automated code quality enforcement and refactoring engine for enterprise C# projects, built on top of the .NET Compiler Platform (Roslyn).

Instead of relying on manual code reviews to enforce architectural guidelines, ArchitectShield acts as a real-time guardian inside your IDE. It analyzes your syntax trees on the fly and provides automatic CodeFix providers to transform legacy or non-compliant code into clean, secure, and standardized structures.

• Real-Time Diagnostics: Analyzes syntax and semantic models to detect architecture violations.
• Syntax Transformation: Automatically rewrites code blocks using SyntaxFactory for zero-friction refactoring.
• Security & Hardcode Prevention: Detects sensitive literals (IPs, connection strings) and routes them to configuration management.
• Pattern Enforcement: Enforces the Result<T> pattern and Async naming conventions across the workspace.

ArchitectShield doesn't just warn you; it writes the boilerplate for you.

Before (Non-compliant code):

public class DataService
{
    public Task<Data> FetchSystemData()
    {
        string connStr = "Server=192.168.1.50;Database=Prod;";
        return _repository.GetData(connStr);
    }
}

After (ArchitectShield applied CodeFix):

public class DataService
{
    public async Task<Result<Data>> FetchSystemDataAsync()
    {
        try
        {
            var connStr = ConfigurationManager.AppSettings["DB_CONNECTION"];
            var data = await _repository.GetDataAsync(connStr);
            
            return Result.Success(data);
        }
        catch (Exception ex)
        {
            // Log integration can be configured
            return Result.Failure<Data>(ex.Message);
        }
    }
}

ArchitectShield is designed with a highly modular, multi-layered architecture:

1. Analysis Engine (DiagnosticAnalyzer): Scans SyntaxNodes (e.g., StringLiteralExpression, MethodDeclaration) and queries the SemanticModel to yield precise diagnostics.
2. Transformation Engine (CodeFixProvider): Consumes diagnostics and utilizes SyntaxFactory and DocumentEditor to safely mutate the syntax tree and update workspace references.
3. Resource Provider: A caching layer that acts as a mock Label Management System, syncing hardcoded strings with a centralized labels.json dictionary.
