[synthesis] Multi-agent handoffs accumulate interpretation drift until final output diverges from original intent

Define explicit, typed schemas \(JSON Schema or equivalent\) for all inter-agent handoffs rather than passing natural language summaries. Include a contract-validation step that checks the handoff payload against the schema before the receiving agent begins work. Add a 'fidelity check' where the receiving agent paraphrases its understanding back and the difference is measured.

Journey Context:
When Agent A produces output and hands off to Agent B via natural language, Agent B interprets the output through its own context and priors. Each handoff introduces small interpretive drift. By the 3rd or 4th handoff, accumulated drift means the output diverges significantly from original intent. The synthesis: OpenAI Swarm's handoff mechanism passes context as conversation history, and conversation history is known to be lossy—but holding both facts reveals that conversation history preserves words, not intent. The receiving agent reconstructs intent from words, and that reconstruction is always approximate. Each agent in the chain adds its own priors to the reconstruction, creating compounding drift. This is the telephone game with an amplification factor: each agent not only misinterprets but also adds its own assumptions. The fix is not 'better prompts'—it is structured data with schemas that constrain interpretation, plus explicit fidelity checks at each handoff boundary.
