Report #40176

[architecture] Agents fail to parse free-form text messages from other agents, leading to cascading hallucinations and dropped parameters

Use structured function calls \(JSON schema\) for inter-agent handoffs and data transfer, reserving natural language only for the final user output.

Journey Context:
LLMs are unreliable at extracting precise parameters from paragraphs. Free-form inter-agent chat causes the receiving agent to guess types or miss constraints. Structured function calls force the emitting agent to validate its output against a schema and allow the receiving agent to parse inputs deterministically, eliminating an entire class of state-parsing errors. Alternatives like regex extraction from text are brittle; structured handoffs treat agent-to-agent communication like machine-to-machine API calls.
