[synthesis] Downstream agent acts on incomplete or ambiguous context received from an upstream agent
Use a strict handoff schema with required fields: goal, constraints, success criteria, known facts, outputs so far, and next-step scope. Add a verification gate that makes the receiving agent restate the task before it executes.
Journey Context:
MAST found that 36.9% of multi-agent failures are coordination breakdowns, with ambiguous handoff and missing context as primary modes. From Spark to Fire models how errors amplify under recursive context reuse. No single source turns these findings into a design contract; the synthesis is that handoff failure is not a communication-quality problem but a missing schema contract. A free-form handoff leaves the receiver to guess which constraints matter, and the receiver's confidence masks the missing information. The common mistake is saying Agent B, please continue. The right call is a structured, validated handoff because an LLM cannot reliably infer requirements that were never stated.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
