[synthesis] Multi-agent handoffs lose implicit context — each agent interprets output literally, compounding misinterpretation across handoffs

Structure handoff payloads as typed schemas with explicit 'implicit\_context' and 'assumptions\_made' fields, not free-form text. The receiving agent must acknowledge these fields before proceeding. Include a 'what\_i\_did\_not\_do' field to prevent the next agent from assuming steps were taken that weren't.

Journey Context:
The drift pattern: Agent A produces output like 'Created the user migration script' — implicitly meaning 'created a draft script that handles the happy path but doesn't handle edge cases for deleted users.' Agent B receives this and interprets it as 'a complete, tested migration script exists.' Agent B builds deployment steps assuming completeness. Agent C runs the deployment and encounters runtime errors from the unhandled edge cases, but now the error manifests in a completely different context, making root-cause analysis nearly impossible. Each handoff acts as a lossy compression step, and the losses compound multiplicatively — not additively. Three handoffs with 90% fidelity each yields 73% fidelity overall. The typed-schema approach is verbose but makes the lossy steps explicit and auditable. The 'what\_i\_did\_not\_do' field is the critical innovation that no single orchestration framework specifies — it captures negative information that free-form handoffs never include but that downstream agents implicitly assume. Without it, agents fill gaps with optimistic defaults.
