Report #55544

[frontier] Agents failing to parse natural language responses from other agents causing cascade failures

Enforce JSON Schema/Pydantic validation on all inter-agent communication using OpenAI Structured Outputs or Instructor library strict mode

Journey Context:
Natural language 'agent soup' creates parsing ambiguity and failures. Leading practitioners are moving to strictly typed interfaces between agents \(similar to gRPC but for LLMs\) eliminating ambiguity via compile-time schema validation.
