Report #4225

[architecture] Agents failing to parse natural language messages from other agents

Enforce structured JSON schema for all inter-agent communication instead of free-form text, treating agent handoffs as typed function calls.

Journey Context:
LLMs are notoriously bad at consistently extracting structured data from unstructured text, leading to cascading parsing errors when Agent B tries to read Agent A's free-form response. Free-form chat is good for human-agent interaction, but agent-agent communication needs a strict contract. By defining handoffs as function calls with JSON Schema, you eliminate extraction ambiguity and make the system debuggable.
