The loop engineering section explains how agents operate as inner while-loops (the ReAct pattern) and discusses the emerging practice of automating the outer loop — removing the human from the iteration cycle — along with real tradeoffs like loss of system understanding, context growth degrading model quality, the need for deterministic stop conditions, and rising costs. The CRAG demo shows a self-assessing RAG workflow built with LlamaIndex, Milvus, Firecrawl, and CometML Opik that falls back to web search when retrieved documents are deemed irrelevant. ## Full article daily.dev links to this article rather than hosting it.
