[synthesis] Multi-agent handoff loses implicit constraints causing downstream agent to contradict upstream decisions

At each agent handoff point, require the sending agent to produce a constraint manifest: an explicit list of invariants, assumptions, and decisions made \(not just the output\). The receiving agent must acknowledge the manifest and validate that its planned actions do not violate any stated constraint before proceeding.

Journey Context:
In multi-agent systems, agents hand off tasks by passing messages. But messages carry only explicit information—the sending agent's implicit assumptions \(e.g., 'I chose PostgreSQL over MongoDB because the schema is relational,' 'I did not add authentication because the spec said internal-only'\) are lost. The receiving agent, operating with incomplete context, makes decisions contradicting these implicit constraints. This is analogous to consistency problems in distributed systems, but the protocol is natural language, which is lossy for implicit information. Increasing context window size does not help because the problem is not capacity—it is that the sending agent does not know what implicit knowledge to articulate. The constraint manifest forces explicit articulation of decisions and their rationale. Manifests add overhead to every handoff and may over-constrain the receiving agent, but they prevent the far more expensive failure of building on contradictory foundations.
