The piece explains graph engineering as a discipline distinct from prompt, context, and loop engineering, describing how structuring agent logic as explicit graphs of workflow steps can offer more control and predictability than freeform agentic loops. ## Content A viral debate over loops versus graphs points to a bigger shift in how we build AI systems. Here’s what graph engineering actually means, how it differs from prompt, context, and loop engineering, and why it matters.
