Report #3134

[architecture] Agents failing to parse arguments passed between each other via natural language

Enforce structured-schema messaging \(e.g., JSON Schema, Pydantic models\) for all inter-agent communication. Never rely on free-form text for parameter passing.

Journey Context:
It is tempting to let agents talk to each other naturally since they are LLMs. However, natural language handoffs inevitably lead to missing parameters, type mismatches, and hallucinated arguments. The receiving agent then fails to execute its tool or requires a clarification loop, burning tokens and time. Structured schemas force the emitting agent to output machine-parseable state, making the contract between agents explicit and testable, similar to microservices API contracts.
