Report #15784

[architecture] Agents failing to parse or hallucinating parameters during inter-agent communication via free-form text

Use structured-schema messaging \(e.g., JSON Schema, tool-call format\) for all agent-to-agent handoffs, treating inter-agent communication as API calls rather than chat.

Journey Context:
LLMs are unreliable at extracting precise action parameters from unstructured text. When Agent A sends a natural language message to Agent B, Agent B often misinterprets constraints or invents missing details. By forcing Agent A to emit a structured JSON payload or a specific tool call that Agent B consumes as input, you shift the burden from semantic interpretation to deterministic parsing. The tradeoff is slightly higher prompt complexity to enforce the schema, but it eliminates an entire class of cascading parsing errors.
