# Hub-and-Spoke Architecture Template
# ====================================
#
# This template demonstrates the Hub-and-Spoke pattern where a central
# agent_router (hub) routes conversations to specialized subagents (spokes).
#
# Pattern: Multi-purpose agents handling distinct request types
# Use when: Users may have different intents (orders, support, returns)

system:

      welcome: "Welcome! I can help with orders, returns, or general support."
      error: "I apologize, something went wrong. Let me try again."
   instructions: "You are a customer service agent for an e-commerce company."
