These vast multi-agentic systems with roles like 'Researcher', 'Writer' (with a review loop), 'Reflection agent', seem to ~feel~ mostly right but lack evals as to the merit of agent decomposition. So it forms a satisfying enough flowchart but I see no evidence these authors actually tried other approaches or agent roles. And let's be honest: an agent is just a system prompt and output contracts, and these rich architectures seem to be pontificating beyond their worth. It all feels a bit vibe-y.
