Report #27069

[architecture] Handoff fails because the receiving agent expects different function schemas than the sender provides

Define a centralized, shared schema registry \(e.g., OpenAPI spec or Pydantic models\) that all agents reference, rather than defining schemas locally per agent.

Journey Context:
In multi-agent systems, Agent A might output a JSON object with camelCase keys, while Agent B expects snake\_case. Local schema definitions drift over time. By centralizing schema definitions in a shared registry and validating inputs/outputs against it at the orchestration layer, you enforce a contract between agents. This shifts the debugging burden from prompt engineering to standard software validation.
