Multi-Agent Architectures

Practise and Check

Deliverable

Specialist retrievers: replace the single router from M30 with a supervisor over three specialist RAG agents and compare routing accuracy and cost.

Larkspur's support swarm sometimes takes a minute to fail. The trace shows billing and operations handing the same customer back and forth until LangGraph raises `GraphRecursionError`. What do you look at, and what do you change?

Common mistakes

• Switching to the specialist team on one judge score for one company
• Letting a yes-or-no critic give the verdict instead of code
• Putting a counter with an adding reducer in the shared TeamState
