A team proposes letting the web search subagent send its results directly to the synthesis subagent instead of returning them to the coordinator, to save a hop. Which two benefits of routing all subagent communication through the coordinator would this give up? Select two.

Answer: A and B — A single place where every handoff between agents can be observed and logged / Consistent handling of subagent errors under one policy at the coordinator

Hub-and-spoke routing through the coordinator provides observability, consistent error handling, and controlled information flow. Subagents never share memory automatically (c), and context must always be passed explicitly in their prompts (d), with or without the coordinator in the path.
