## Integration Guidelines

### For Plugin Developers

```csharp
// Example usage of new infrastructure in plugins
public async Task<AIPluginResult> ExecuteAsync(Dictionary<string, object> parameters, CancellationToken cancellationToken)
{
    var validator = new InputValidator();
    var context = new AnalysisContext(configuration);
    
    try
    {
        // Validate inputs
        var validationResult = validator.ValidatePluginParameters(parameters);
        if (!validationResult.IsValid)
            return AIPluginResult.Error(validationResult.ErrorMessage);

        // Execute with error handling and retry logic
        var result = await ErrorHandling.ExecuteWithRetryAsync(
            () => PerformAnalysisAsync(parameters, context.CancellationToken),
            maxRetries: 3,
            logger: logger,
            cancellationToken: cancellationToken
        );

        return AIPluginResult.Success(result);
    }
    catch (Exception ex)
    {
        var errorInfo = ErrorHandling.HandlePluginException(ex, "MyPlugin", "ExecuteAsync", logger);
        return AIPluginResult.Error(errorInfo.Exception.Message);
    }
    finally
    {
        context.Dispose();
    }
}
```

### For Analysis Orchestration

```csharp
// Example usage of result aggregation
var pluginDiscovery = new PluginDiscoveryService(logger);
var resultAggregator = new AnalysisResultAggregator(logger);
var plugins = pluginDiscovery.GetBuiltInPlugins();

var results = new List<AIPluginResult>();
foreach (var plugin in plugins)
{
    var result = await plugin.ExecuteAsync(parameters, cancellationToken);
    results.Add(result);
}

var aggregatedResult = await resultAggregator.AggregateAsync(results);
var summaryReport = await resultAggregator.GenerateSummaryAsync(aggregatedResult);
```
