[synthesis] Critical context lost during multi-agent handoffs causes downstream agents to operate on wrong assumptions

Implement a shared structured state object with mandatory schema validation at handoff boundaries. Require each receiving agent to echo back key constraints before proceeding with work.

Journey Context:
In multi-agent frameworks like OpenAI Swarm, handoffs transfer conversation history but not structured state. Each agent interprets free-text history through its own lens, losing nuance and constraints. The compounding effect is devastating: Agent A decides 'use the staging API endpoint,' Agent B doesn't see this detail in its truncated context, uses production, and Agent C builds on Agent B's production work. By the time anyone notices, production data is corrupted. The naive fix—passing full history—causes context overflow in the receiving agent. Another wrong fix is summarizing, but summarization is lossy and drops exactly the edge-case constraints that matter most. The right fix is a structured shared state with schema enforcement \(like a database transaction log\), combined with a handoff protocol where the receiving agent must acknowledge key constraints before acting. This synthesizes Swarm's handoff mechanics with database transaction isolation concepts—no single source makes this connection.
