Report #58846

[architecture] Agents failing to parse handoff arguments or hallucinating parameters during delegation

Enforce structured-schema \(JSON\) messaging for inter-agent communication and handoffs, rather than relying on free-form natural language.

Journey Context:
LLMs are unreliable at extracting structured data from unstructured text when passing state. Free-form handoffs lead to dropped variables, hallucinated fields, or misaligned expectations. JSON schema forces the emitting LLM to output exactly what the receiving agent's function signature expects, turning a fuzzy NLP problem into a deterministic API contract.
