Report #5298

[architecture] Agents hallucinating or failing to parse parameters when passing free-form natural language to each other

Use structured JSON schemas or function calls for inter-agent communication instead of free-form text strings.

Journey Context:
While natural language seems flexible, LLMs frequently omit required parameters or hallucinate formats when generating text for another LLM to parse. Using function calling \(structured JSON\) as the interface between agents creates a strict contract, eliminating parsing failures and making debugging deterministic.
