A team of AI consultants charges $10,000 to design a multi-agent workflow most tasks never actually needed! The real question costs nothing: could this collapse back into one agent's loop and lose nothing? A single agent running a research, write, review, ship loop works fine right up until the task stops being one job. Cram distinct specialties into one loop and the agent loses the thread. → the trigger: one loop stops being the right shape once a task splits into distinct specialties that hand off to each other → the fix: give each job its own node, wire them together, let state flow between them → the honest catch: langgraph, Microsoft's autogen, and Google's adk already shipped this exact node-edge-state model before the term existed → what's actually new: not the mechanics, just a shared name for a design decision teams were already being forced into The gap between people adding boxes to a diagram for fun and people who actually needed the coordination is one question. Could this collapse back into one agent's loop and lose nothing? If yes, it should. Bookmark so you do not lose it! Follow @neil_xbt for more AI content!
