Question

You are building a multi-agent research system using the Claude Agent SDK. A coordinator agent delegates to specialized subagents: one searches the web, one analyzes documents, one synthesizes findings, and one generates reports. The system researches topics and produces comprehensive, cited reports.

Production monitoring shows the research phase takes longer than expected. Analysis reveals the coordinator invokes the web search subagent, waits for its response, then invokes the document analysis subagent and waits again. These tasks are independent – neither requires the other's output.

How should you modify the system to run these subagents concurrently?

Accepted Answer

D. Structure the coordinator to emit both Task tool calls (for web search and document analysis) in a single response message rather than across separate conversation turns.

Answer

A. Create an async orchestration layer outside the agent that spawns parallel threads, each running a separate coordinator-subagent pair, then aggregates results.

Answer

B. Add detailed instructions to the coordinator's system prompt explaining the performance benefits of parallel execution and requesting it invoke both subagents at the same time.

Answer

C. Switch both subagents to use a Haiku-tier model instead of Sonnet to reduce their individual execution time.
