## Nauti's Take

The useful test is to run your own multi-part questions through both single-shot and agentic retrieval, then inspect the traces and measure cost, latency, and source quality. Adopt the extra orchestration only when those additional steps consistently produce better evidence in workflows that matter to your team.
