This Is Why Your Main Agent Shouldn't Read Every Trace
Screener sub-agents read full traces so the main agent's context stays manageable
“we're really familiar with designing an org chart, in a way”
LangChain describes a production multi-agent pattern where cheap, fast screener sub-agents consume full traces and surface only interesting signals to a main agent, preserving its context window. A verifier agent adds a final lightweight check before issues are filed. The team frames this as an org-chart model: capable generalist at the top, specialized cheaper workers below — a reusable design heuristic for anyone building multi-agent observability pipelines.
