Report #67580
[synthesis] Multi-agent handoffs cause edge-case data loss leading to downstream schema failures
Enforce strict schema-to-schema handoffs \(e.g., Pydantic models or JSON Schema\) between agents instead of natural language summaries, explicitly including fields for null/edge cases.
Journey Context:
To save tokens, Agent A extracts data and passes a natural language summary to Agent B. Agent B assumes the summary is exhaustive and builds a database schema. Agent C inserts data, but missing edge cases from the original source cause foreign key violations. The compounding error is that the 'efficiency' of summarization strips out the very anomalies that break downstream deterministic systems. The synthesis links LLM summarization tendencies \(which favor general patterns over outliers\) with rigid downstream schema constraints: the summary optimizes for the norm, guaranteeing catastrophic failure on the edge case.
