[EN-B020-039] Multiple Agents Interaction: Contract-Net Router + Budget Arbitration

Overview​

A practical evolution of multi-agent systems is the contract-net pattern: planner agents publish tasks, specialists bid with confidence/cost, and an arbiter assigns work under token/time budgets.

Use Case​

  • Planner posts machine-readable task contracts to a shared queue.
  • Specialists return bids (latency, confidence, expected token burn).
  • Arbiter selects winners, triggers execution, and reassigns on SLA breach.

Tools Used​

  • sessions_spawn: planner, specialist, and arbiter roles
  • sessions_send: bid exchange and reassignment handoff
  • sessions_history: accountability trail for arbitration decisions
  • cron: recurring benchmark rounds to tune routing policy

Trend Signals (2026 Q1)​

  • Recently updated multi-agent orchestration repos explicitly compare parallel high-code vs autonomous lanes (example: nexus-ai-orchestrator).
  • Self-hosted orchestration stacks on commodity devices (e.g., Mac mini) are emphasizing multi-agent throughput.
  • Discord-controllable orchestration services are growing as operators want chat-native control planes (example: gru).
