Liam Ottley. Customer support agents are Liam's bread-and-butter use case, and a sizeable chunk of this course is given over to RAG-grounded chatbots, escalation logic, and the no-code stack he uses with real clients (Botpress, Voiceflow, Make, n8n). The "anatomy of an agent" section in particular maps almost one-to-one onto the article's triage → answer → action → handoff structure.
