[architecture] CrewAI-style multi-agent roleplay over-promises autonomous workflows; why explicit state machines usually win

Model multi-agent work as a state machine with explicit handoffs, not as autonomous 'crew members' negotiating. Define each node's responsibility, the events that trigger transitions, and a shared schema for state. Use role prompts only to shape style inside a node, not to drive coordination.

Journey Context:
CrewAI and AutoGen popularized the idea that agents with names and roles will self-organize. In practice, unconstrained delegation leads to infinite loops, hallucinated consensus, and opaque failures. The better pattern is hierarchical or finite-state coordination: a router decides which worker runs next, each worker reads and writes a typed state object, and termination is explicit. This mirrors reliable distributed systems \(workflow engines, actor mailboxes\) rather than emergent collaboration. Use role-based frameworks for demos; use explicit state machines for production.
