Three terms now compete for the same line in AI engineering job descriptions. Prompt engineering is the established one. Loop engineering entered the AI vocabulary in late 2025 and dominated developer discussion through June 2026. Graph engineering followed roughly six weeks later.
They get used interchangeably. Should they be?
The three are not competing techniques. They are three different units of control, stacked. A prompt controls one model response. A loop controls one agent’s behavior cycle. A graph controls the organization of many agents. Each layer preserves the layer beneath it. A prompt does not disappear once a loop is built around it. it stops being the thing typed by hand.
This article separates the three: what gets designed at each layer, what the published claim says about when the higher layers pay for themselves, and where the skepticism is warranted.
The stack, in order
Each step in the progression was named in practice before it appeared in vendor documentation.
Prompt engineering covers writing and structuring the instruction for a single call. Anthropic’s guidance is to separate a system prompt into labeled sections — background information, instructions, tool guidance, output description — delineated with XML tags or Markdown headers. The recommendation is to supply the minimal set of information that fully specifies the expected behavior. Minimal does not mean short.
Context engineering came next. Anthropic describes it as the natural progression of prompt engineering. The question moves from finding the right words to deciding what …
