[synthesis] Error propagation across multi-agent handoffs via lossy context summarization
Pass raw, structured data \(JSON/AST\) between agents instead of natural language summaries, and enforce schema validation at the receiving agent's entry point.
Journey Context:
Multi-agent frameworks often use natural language summaries for handoffs to save tokens. Information theory dictates this is lossy compression. When Agent A summarizes a file structure for Agent B, it might omit a critical detail \(like a symlink target\). Agent B, forced to act, hallucinates the missing detail with high confidence. By step C, the hallucination is treated as ground truth. The synthesis of multi-agent orchestration and LLM sycophancy reveals that inter-agent communication must be treated like inter-service communication: schema-bound and structured, not conversational. The cost of higher token usage is vastly cheaper than the compounding cost of a confident hallucination executing destructive writes.
