[synthesis] Multi-agent handoffs cause exponential information loss through summarization

Pass references \(e.g., URIs, file paths, or database IDs\) rather than summarized content between agents, and enforce strict schema validation at handoff boundaries.

Journey Context:
When Agent A summarizes data for Agent B to save token costs, it inevitably drops edge cases or precise formatting. Agent B treats this summary as ground truth, compounding the error when it passes it to Agent C. This resembles the telephone game. Developers often try to fix this by asking for 'more detailed summaries,' which only increases token cost without solving the structural information loss. The synthesis of information theory \(lossy compression\) and multi-agent orchestration shows that inter-agent communication must be reference-based, pulling raw data on demand, to prevent compounding fidelity loss.
