Report #14068

[architecture] Agents fail to parse each other's outputs when using natural language for inter-agent communication

Enforce structured-schema \(JSON\) for all inter-agent messages, reserving natural language strictly for user-facing outputs.

Journey Context:
LLMs are stochastic; free-form text between agents leads to parsing errors, missing arguments, and infinite loops of 'I didn't understand'. JSON schema enforces a strict contract. Tradeoff: slightly higher token cost for schema overhead and stricter prompt engineering, but yields a massive reduction in coordination failures and eliminates fragile regex parsing of conversational text.
