Quick Start: Multi-Agent Documentation Integration

This guide shows you how to integrate the multi-agent documentation system into Semantico in under 30 minutes.

Step 1: Register Service (2 minutes)

Edit Semantico.Core/ServiceConfiguration.cs:

public static IServiceCollection AddSemantico(
    this IServiceCollection services,
    IConfiguration configuration,
    Action<SemanticoConfiguration> configure)
{
    // ... existing code ...

    // AI Services
    services.AddSingleton<IAiDocumentationService, AiDocumentationService>();
    services.AddSingleton<IMultiAgentDocumentationService, MultiAgentDocumentationService>(); // ADD THIS LINE

    // ... rest of code ...
}

Step 2: Create Handler (10 minutes)

Create Semantico.Core/Handlers/Documentation/GenerateMultiAgentDocumentationHandler.cs:

using MediatR;
using Semantico.Core.Data.Entities;
using Semantico.Core.Models.Ai.MultiAgent;
using Semantico.Core.Services.Ai.MultiAgent;

namespace Semantico.Core.Handlers.Documentation;

internal sealed class GenerateMultiAgentDocumentationHandler(
    IMultiAgentDocumentationService multiAgentService)
    : IRequestHandler<GenerateMultiAgentDocumentationCommand, DataSourceDocumentation>
{
    public async Task<DataSourceDocumentation> Handle(
        GenerateMultiAgentDocumentationCommand request,
        CancellationToken cancellationToken)
    {
        var options = new MultiAgentGenerationOptions
        {
            MaxConcurrentAgents = request.MaxConcurrentAgents ?? 5,
            MinTablesPerDomain = 3,
            MaxDomainsToIdentify = 7,
            Temperature = 0.3m,
            EnableOrchestratorCache = true,
            OrchestratorCacheDurationMinutes = 60,
            SpecificTables = request.SpecificTables,
            ExcludedTables = request.ExcludedTables,
            MaxTables = request.MaxTables ?? 200,
            Title = request.Title
        };

        return await multiAgentService.GenerateDocumentationAsync(
            request.DataSourceId,
            request.UserId,
            options,
            request.Progress,
            cancellationToken);
    }
}

public record GenerateMultiAgentDocumentationCommand : IRequest<DataSourceDocumentation>
{
    public int DataSourceId { get; init; }
    public int UserId { get; init; }
    public int? MaxConcurrentAgents { get; init; }
    public List<string>? SpecificTables { get; init; }
    public List<string>? ExcludedTables { get; init; }
    public int? MaxTables { get; init; }
    public string? Title { get; init; }
    public IProgress<DocumentationProgress>? Progress { get; init; }
}

Step 3: Update UI Dialog (15 minutes)

Edit Semantico.UI/Components/Pages/DataSources/GenerateDocumentationDialog.razor:

Add field:

@code {
    // ... existing fields ...

    private bool _useMultiAgent = true; // ADD THIS
    private string? _progressMessage; // ADD THIS
    private int _progressPercent; // ADD THIS
}

Add toggle to form:

<MudSwitch
    @bind-Checked="_useMultiAgent"
    Color="Color.Primary"
    Label="Use Multi-Agent Workflow" />
<MudText Typo="Typo.caption" Color="Color.Secondary">
    Faster for large databases (30+ tables), uses multiple specialized AI agents
</MudText>

Add progress indicator:

@if (_isGenerating)
{
    <MudProgressLinear Value="_progressPercent" Color="Color.Primary" Class="my-4" />
    <MudText Typo="Typo.body2" Align="Align.Center">@_progressMessage</MudText>
}

Update submit method:

private async Task OnSubmitAsync()
{
    _isGenerating = true;
    _progressPercent = 0;
    _progressMessage = "Starting documentation generation...";

    try
    {
        if (_useMultiAgent)
        {
            var progress = new Progress<DocumentationProgress>(p =>
            {
                _progressPercent = p.PercentComplete;
                _progressMessage = p.StatusMessage;
                InvokeAsync(StateHasChanged);
            });

            var command = new GenerateMultiAgentDocumentationCommand
            {
                DataSourceId = _dataSourceId,
                UserId = _currentUserId,
                MaxConcurrentAgents = 5,
                Title = _title,
                Progress = progress
            };

            var result = await Mediator.Send(command);
            // Handle result
        }
        else
        {
            // Use existing single-agent flow
        }
    }
    finally
    {
        _isGenerating = false;
    }
}

Step 4: Test It! (5 minutes)

Basic Test:

// In your test or sample project
var service = serviceProvider.GetRequiredService<IMultiAgentDocumentationService>();

var progress = new Progress<DocumentationProgress>(p =>
{
    Console.WriteLine($"[{p.PercentComplete}%] {p.StatusMessage}");
});

var options = new MultiAgentGenerationOptions
{
    MaxConcurrentAgents = 5,
    EnableOrchestratorCache = true
};

var documentation = await service.GenerateDocumentationAsync(
    dataSourceId: 1,
    userId: 1,
    options: options,
    progress: progress,
    cancellationToken: CancellationToken.None
);

Console.WriteLine($"Documentation generated!");
Console.WriteLine($"Tables: {documentation.TablesAnalyzed}");
Console.WriteLine($"Tokens: {documentation.TokensUsed}");
Console.WriteLine($"Cost: ${documentation.EstimatedCost:F4}");

Expected Console Output:

[10%] Analyzing database schema and identifying domains...
[30%] Documenting User Management (1/5)...
[50%] Documenting Order Processing (2/5)...
[70%] Documenting Notification System (3/5)...
[82%] Documenting Data Pipeline (4/5)...
[90%] Documenting Audit & Logging (5/5)...
[95%] Combining and refining documentation...
[100%] Processing...
Documentation generated!
Tables: 52
Tokens: 24580
Cost: $0.0368

Step 5: Configuration (Optional)

Add to appsettings.json:

{
  "Semantico": {
    "AI": {
      "MultiAgent": {
        "Enabled": true,
        "MaxConcurrentAgents": 5,
        "MinTablesPerDomain": 3,
        "MaxDomainsToIdentify": 7,
        "EnableOrchestratorCache": true,
        "OrchestratorCacheDurationMinutes": 60,
        "DefaultForLargeDatabases": true,
        "LargeDatabaseThreshold": 30
      }
    }
  }
}

Troubleshooting

Issue: “Service not registered”

Solution: Make sure you added IMultiAgentDocumentationService to ServiceConfiguration.cs

Issue: “JSON parsing failed”

Solution: Check LLM response in logs. The LLM might be returning markdown-wrapped JSON. The ExtractJsonFromResponse() method should handle this, but you can add additional cleaning logic if needed.

Issue: “Orchestrator returns 0 domains”

Solution: Check that tables are being passed correctly. Validate that metadata.Tables has data.

Issue: “Domain agent timeout”

Solution: Increase MaxTokens in options or reduce MinTablesPerDomain to create smaller domains.

Issue: “Cache not working”

Solution: Ensure IMemoryCache is registered in DI. It should be added automatically by ASP.NET Core, but you can explicitly add it:

services.AddMemoryCache();

Performance Tips

For Small Databases (<20 tables)

Single-agent might be faster due to parallel overhead
Set MaxConcurrentAgents = 3 to reduce overhead

For Medium Databases (20-60 tables)

Multi-agent provides 2-3x speedup
Default settings work well

For Large Databases (60+ tables)

Multi-agent provides 4-5x speedup
Consider increasing MaxConcurrentAgents to 7
Enable orchestrator cache for repeated generations

Cost Optimization

var options = new MultiAgentGenerationOptions
{
    Temperature = 0.1m, // More deterministic = fewer tokens
    MaxTokens = 3000,   // Limit per-agent output
    MaxConcurrentAgents = 3 // Reduce parallelism if rate-limited
};

Monitoring

Log Analysis

Check logs for:

Token usage per phase
Time per domain
Cache hit rate
Error frequency

Metrics to Track

// Add custom metrics
var stopwatch = Stopwatch.StartNew();
var doc = await service.GenerateDocumentationAsync(...);
stopwatch.Stop();

_metrics.RecordDocumentationGeneration(
    databaseSize: doc.TablesAnalyzed,
    tokensUsed: doc.TokensUsed,
    duration: stopwatch.Elapsed,
    cost: doc.EstimatedCost
);

Next Steps

Add to UI navigation: Link to multi-agent option from data source detail page
Compare outputs: Generate docs with both single and multi-agent, compare quality
Optimize prompts: Refine MultiAgentPrompts.cs based on output quality
Add tests: Create unit and integration tests
Enable by default: After testing, make multi-agent the default for databases >30 tables
