Report #58184

[architecture] Unstructured text handoffs between agents cause cascading parsing failures

Enforce strict JSON Schema contracts for all inter-agent messages, treating the receiving agent's input parser like an API endpoint.

Journey Context:
Developers often let agents chat in natural language because LLMs excel at it. However, slight variations in formatting \(e.g., adding 'Here is the JSON:'\) break the next agent's regex or JSON parser. By enforcing a strict schema contract, the sending agent is constrained to produce machine-parseable output, and the receiving agent can validate before processing. The tradeoff is slightly higher token usage for schema adherence, but it eliminates an entire class of deterministic parsing errors in probabilistic systems.
