Plugin Kernel Orchestrator

Software componentOrchestrationOrchestration & Toolsarc:PluginKernelOrchestrator

A central workflow orchestrator that manages service registration, dependency injection and plugin discovery, and routes each request to registered plugin functions selected by LLM-driven function calling.

Responsibility. Routes requests dynamically to registered capability plugins.

Also known as: Kernel, Semantic Kernel kernel, Plugin router

Variant of Workflow Orchestrator abstract

When to choose. Choose for enterprise agent ecosystems with dozens of specialized capabilities, evolving service catalogs and existing-system integration needing central orchestration; avoid for focused single-purpose agents where plugin abstraction is over-engineering.

Design guidance

SHOULD add new capabilities by registering plugins without modifying core orchestration logic.
SHOULD use dependency injection to centralize monitoring, token tracking and observability across plugins.
