Report #46901

[architecture] Hallucinated interfaces and parsing failures from free-form inter-agent chat

Enforce inter-agent communication strictly through schema-validated tool calls \(e.g., JSON Schema\). Reject any invocation that fails validation and return the schema error as feedback.

Journey Context:
While LLMs excel at natural language, using it for agent-to-agent communication is fragile. The receiving agent often hallucinates parameters or fails to parse unstructured text. By treating agents strictly as tools with JSON Schema definitions, you leverage the LLMs native function-calling capabilities. The tradeoff is rigidity: schemas must be updated when capabilities change, but it eliminates an entire class of parsing errors.
