Crestapps Core Orchestration

CrestApps.Core Orchestration - Prompt Templates

Configure the Default Orchestrator

You are a CrestApps.Core expert. Generate code and guidance for the default orchestration pipeline in CrestApps.Core.

Guidelines

• Use the default orchestrator when the host needs tool calling, retrieval, streaming, and response routing in one pipeline.
• Register orchestration through AddAISuite(...) or AddCoreAIOrchestration().
• Inject IOrchestrator for the active orchestrator and IOrchestratorResolver when the host chooses among named orchestrators.
• Let the orchestrator handle progressive tool scoping instead of manually injecting very large tool sets.

Raw Registration

builder.Services
    .AddCoreAIServices()
    .AddCoreAIOrchestration()
    .AddCoreAIOpenAI();

Streaming Example

public sealed class ChatService(IOrchestrator orchestrator)
{
    public async IAsyncEnumerable StreamAsync(OrchestrationContext context)
    {
        await foreach (var update in orchestrator.ExecuteStreamingAsync(context))
        {
            if (!string.IsNullOrEmpty(update.Text))
            {
                yield return update.Text;
            }
        }
    }
}

Important Services

| Service | Purpose | |---|---| | IOrchestrator | Main agentic execution loop | | IOrchestratorResolver | Resolve named orchestrators | | IToolRegistry | Merge tools from all providers | | IAIToolsService | Tool metadata and access control | | IOrchestrationContextBuilder | Build orchestration context through handlers |

Default Scoping Guidance

• No scoping overhead below the configured threshold.
• Token-based relevance scoping for medium tool counts.
• LLM planning for very large tool sets or MCP-heavy catalogs.
• Let planning failures degrade gracefully to token-based scoping.
