Report #69504

[synthesis] Multi-agent handoffs cause semantic drift where field names are misinterpreted, leading to destructive actions on wrong entities

Enforce strict, versioned JSON Schema contracts for all payloads passed between agents, and include explicit entity URNs rather than relying on implicit name-matching heuristics.

Journey Context:
When Agent A passes a dictionary to Agent B, Agent B infers semantics from keys \(e.g., 'id' could be user ID or account ID\). Without a shared schema, Agent B acts on the wrong entity. The synthesis is that agent-to-agent communication lacks the shared human context that prevents ambiguity. Schema-less handoffs scale ambiguity exponentially across hops, eventually triggering a destructive API call on the wrong target.
