Report #48076

[architecture] Agents communicating via unstructured natural language strings leading to cascading parsing failures

Enforce strict JSON schema for inter-agent messaging, treating agent handoffs exactly like API contracts.

Journey Context:
LLMs are unreliable at extracting structured data from paragraphs. Free-form text between agents leads to hallucinated parameters and cascading parsing errors. Structured schemas allow programmatic validation and fail-fast mechanisms. The tradeoff is slightly higher prompt complexity for massive gains in reliability.
