Report #10175

[architecture] Agents hallucinating parameters or failing to extract intent from free-form natural language messages sent by other agents

Use strongly-typed JSON schemas for all inter-agent communication. Reserve natural language strictly for the final user-facing output.

Journey Context:
LLMs are unreliable parsers of unstructured text when precise arguments \(like file paths, line numbers, or configuration flags\) are required. Free-form chat between agents leads to cascading extraction errors. JSON schemas act as an API contract between agents, ensuring machine-readable fidelity.
