Report #53531

[architecture] Agents failing to extract required parameters from free-form text messages passed between them

Use strictly typed schemas \(e.g., JSON Schema, Pydantic models\) for all inter-agent communication and tool responses, rather than passing natural language strings.

Journey Context:
Relying on an LLM to parse unstructured text to extract exact parameters leads to hallucinations and dropped variables. Structured schemas allow the receiving agent's pre-processing layer to validate inputs programmatically before the LLM even sees them, guaranteeing that required fields exist.
