Report #54352
[architecture] Multi-agent chain fails midway due to context window overflow from passing full conversation histories
Implement state summarization or structured memory retrieval at handoff boundaries. Pass only the schema-validated output and a compressed summary of relevant context, not the raw transcript.
Journey Context:
Naive multi-agent systems just append messages to a single growing list. This quickly hits token limits and degrades the reasoning of downstream agents due to lost-in-the-middle effects. The tradeoff is between context richness and token efficiency. Summarization/structured state is the right call because downstream agents usually only need the specific artifact, not the entire thought process.
