Report #16950

[architecture] Agents failing to parse instructions or hallucinating parameters during handoffs

Use structured JSON function calls for inter-agent communication and handoffs instead of free-form natural language messages.

Journey Context:
When agents communicate via natural language \(e.g., 'Hey Agent B, please book a flight to X for user Y'\), the receiving agent must parse and extract parameters, leading to hallucinations, dropped parameters, and fragility. By treating inter-agent handoffs as structured function calls \(tool calls\), the LLM is forced to generate valid, schema-compliant arguments, making the coordination deterministic and the state transfer reliable.
