Agentic Development · Architecture
A component (often itself an LLM) that manages the overall workflow: deciding which sub-agent or tool to invoke next, passing outputs between steps, and tracking progress toward the goal.
Example: In LangGraph, a supervisor node reads the latest state and routes to either the 'researcher' or 'writer' node depending on what's still needed.
In practice: The orchestrator is where most of the agent's strategic reasoning lives. A weak orchestrator leads to loops, skipped steps, or tasks that silently fail.
