D1 Agentic Architecture & Orchestration · Paper 3

[Scenario 3: Multi-Agent Research System] A coordinator agent built on the Claude Agent SDK delegates to specialized subagents — web search, document analysis, synthesis, and report generation — to research topics and produce comprehensive, cited reports. Completed reports are coherent but shallow on some subtopics. You want the system to notice and repair its own coverage gaps before finalizing. Which orchestration pattern achieves this?

• A.Lower the bar: accept the first synthesis as final to control costs
• B.An iterative refinement loop: the coordinator evaluates synthesis output for gaps, re-delegates to search and analysis subagents with targeted queries, and re-invokes synthesis until coverage is sufficient
• C.Ask the report generation agent to pad thin sections with general knowledge
• D.Always run every subagent exactly twice regardless of output quality

Show answer & explanations

Correct answer: B

A: ships the known defect

B: Iterative refinement closes the quality loop: evaluate coverage, dispatch targeted follow-up research where gaps exist, re-synthesize — repeating until the report meets criteria rather than hoping the first pass suffices.

C: fills gaps with uncited generalities — the opposite of a cited research product

D: doubles cost blindly with no gap-detection to aim the second pass
