Play 07 — Multi-Agent Service 🤖

Supervisor agent routes to specialist agents with shared state and handoff protocol.

A supervisor agent receives requests, classifies intent, and delegates to specialist agents. Each agent has its own model config, tools, and memory. Loop prevention and max-iteration guards keep costs predictable.

Quick Start


cd solution-plays/07-multi-agent-service
az deployment group create -g $RG -f infra/main.bicep -p infra/parameters.json
code .  # Use @builder for topology, @reviewer for loop detection, @tuner for routing
