## 🚀 Quick Start

### Basic Usage

```csharp
using MarketAlly.AIPlugin.Analysis.Infrastructure;
using MarketAlly.AIPlugin.Analysis.Plugins;

// Initialize infrastructure
var config = new AnalysisConfiguration
{
    MaxConcurrentAnalyses = Environment.ProcessorCount,
    EnableCaching = true,
    DefaultTimeout = TimeSpan.FromMinutes(5)
};

var pluginDiscovery = new PluginDiscoveryService();
var resultAggregator = new AnalysisResultAggregator();

// Get built-in plugins
var plugins = pluginDiscovery.GetBuiltInPlugins();

// Execute analysis with error handling
using var context = new AnalysisContext(config);
var results = new List<AIPluginResult>();

foreach (var plugin in plugins)
{
    var result = await ErrorHandling.ExecuteWithRetryAsync(
        () => plugin.ExecuteAsync(parameters, context.CancellationToken),
        maxRetries: 3
    );
    results.Add(result);
}

// Aggregate and analyze results
var aggregatedResult = await resultAggregator.AggregateAsync(results);
var summaryReport = await resultAggregator.GenerateSummaryAsync(aggregatedResult);

Console.WriteLine($"Code Health Score: {aggregatedResult.HealthAssessment.Score:F1}");
Console.WriteLine($"Total Issues: {aggregatedResult.AllIssues.Count}");
```

### Performance-Optimized Analysis

```csharp
// Use performance optimization features
var perfOptimizer = new PerformanceOptimization();

// Parallel analysis execution
var analysisResults = await perfOptimizer.ExecuteInParallelAsync(
    filesToAnalyze,
    async file => await AnalyzeFileAsync(file),
    maxConcurrency: Environment.ProcessorCount
);

// Cached analysis results
var cachedResult = await perfOptimizer.GetOrSetCacheAsync(
    $"analysis_{projectPath}",
    () => PerformExpensiveAnalysisAsync(projectPath),
    TimeSpan.FromHours(1)
);
```

### Advanced Configuration

```csharp
var config = new AnalysisConfiguration
{
    DefaultTimeout = TimeSpan.FromMinutes(10),
    MaxConcurrentAnalyses = Environment.ProcessorCount * 2,
    EnableCaching = true,
    CacheExpirationTime = TimeSpan.FromHours(2),
    AllowDynamicPluginLoading = true,
    TrustedPluginDirectory = "plugins/",
    DefaultParameters = new Dictionary<string, object>
    {
        ["analyzeComplexity"] = true,
        ["suggestOptimizations"] = true,
        ["includeArchitectureAnalysis"] = true
    }
};
```

## 🔧 Plugin Development

### Creating Custom Plugins

```csharp
[AIPlugin("MyAnalyzer", "Custom analysis plugin")]
public class MyAnalyzerPlugin : IAIPlugin
{
    public Dictionary<string, ParameterInfo> SupportedParameters => new()
    {
        ["projectPath"] = new ParameterInfo { Type = typeof(string), Required = true },
        ["depth"] = new ParameterInfo { Type = typeof(string), Required = false }
    };

    public async Task<AIPluginResult> ExecuteAsync(Dictionary<string, object> parameters, CancellationToken cancellationToken)
    {
        // Validate inputs
        var validator = new InputValidator();
        var validationResult = validator.ValidatePluginParameters(parameters);
        if (!validationResult.IsValid)
            return AIPluginResult.Error(validationResult.ErrorMessage);

        // Perform analysis with error handling
        return await ErrorHandling.SafeExecuteAsync(async () =>
        {
            var analysis = await PerformAnalysisAsync(parameters, cancellationToken);
            return AIPluginResult.Success(analysis);
        });
    }
}
```

### Plugin Registration

```csharp
// Register plugins dynamically
var pluginDiscovery = new PluginDiscoveryService();

// Load from directory
var externalPlugins = await pluginDiscovery.DiscoverPluginsAsync("plugins/");

// Load specific plugin
var specificPlugin = await pluginDiscovery.LoadPluginAsync("MyPlugin.dll", "MyPlugin.Analyzer");

// Validate plugin
bool isValid = pluginDiscovery.ValidatePlugin(specificPlugin);
```

var healthAssessment = aggregatedResult.HealthAssessment;
Console.WriteLine($"Overall Health: {healthAssessment.Rating}");
Console.WriteLine($"Score: {healthAssessment.Score:F1}/100");
Console.WriteLine($"Description: {healthAssessment.Description}");

// Component-specific scores
foreach (var component in healthAssessment.ComponentScores)
{
    Console.WriteLine($"{component.Key}: {component.Value:F1}");
}
```
