Fable
An orchestra that can improvise even with a full score
A caravan has to cross a desert, negotiate tax checkpoints, repair wheels, and care for the sick. An all-purpose steward cannot go deep into every matter at once, yet if everyone goes their own way, the water bags, route, and caravan will fall out of sync with one another.
The team leader retains the route and high-risk decisions, while the guide, accountant, craftsman and healer each handle specialized tasks. Each role knows its inputs, outputs and handoff timing, and local work does not need to go back to the team leader for everything.
The itinerary board records the current location, cargo, permits, and open issues. After one master completes a task, he updates the board, and the next master takes over from the same state, avoiding each maintaining contradictory memories.
Low-risk repairs could be decided directly by the craftsmen, while tax-card disputes or worsening conditions went back to the team leader for judgment. Central orchestration, hierarchical approval, and local autonomy were thus combined in one traceable process.
The point of hybrid multi-agent systems is not to pile up more Agents, but to choose the appropriate control topology for different risks and levels of expertise, and to define clear boundaries for synchronization, handover and escalation.
