From loops to graphs: why complex agent systems are shifting to graph engineering
Pavan_Belagatti · x · 2026-09-05
The author argues agentic systems are shifting from simple loops to deliberate Graph Engineering: Loop Engineering runs an agent in continuous reasoning/tool-selection cycles, suited to simple open-ended tasks, while Graph Engineering treats the system like an org chart—engineers define nodes (agents or deterministic functions) and edges (data flow) with fan-out, join, and router patterns, providing the control and debuggability needed for complex multi-step workflows like automated PR pipelines.
