Report #45291

[architecture] Agents fail to parse responses from other agents due to unstructured natural language

Enforce structured-schema \(JSON\) messaging for all inter-agent communication; reserve natural language only for the final user-facing output.

Journey Context:
LLMs generate fluent text, but parsing it reliably in an automated pipeline is brittle. When Agent A returns 'I couldn't find the file' versus a JSON \{"status": "error", "code": "FILE\_NOT\_FOUND"\}, Agent B might hallucinate a fix or fail. The tradeoff is slightly higher token cost and rigidity, but it eliminates cascading parsing errors. Alternatives like regex extraction fail on edge cases. Structured outputs are the right call for machine-to-machine interfaces.
