[EN-B017-030] Multiple Agents Interaction: Arbiter-and-Witness Pattern

Overview​

Teams are moving beyond simple manager-worker chains by adding an Arbiter agent and a Witness agent to reduce silent failures and conflicting actions.

Use Case​

  • Worker agents produce parallel plans with evidence links.
  • Arbiter agent resolves conflicts and selects one actionable path.
  • Witness agent verifies policy and factual consistency before final execution.

Tools Used​

  • sessions_spawn: parallel specialist workers plus arbiter/witness roles
  • sessions_send: structured challenge prompts and correction loops
  • sessions_history: evidence tracing across agent turns
  • cron: periodic swarm drills to benchmark coordination quality

Trend Signals (2026 Q1)​

  • Multi-agent GitHub repos increasingly add explicit arbitration layers rather than relying on a single planner.
  • Discord builders report better reliability when one agent is dedicated to contradiction detection.
  • Chinese communities discuss this as "仲裁+见证双保险", especially for finance and ops automation.
