[architecture] Agent misinterprets tool output \(e.g., API error, empty array\) and passes a false summary to the next agent

Implement schema validation on tool outputs before the agent processes them. Map standard API errors to explicit structured messages the agent cannot misinterpret \(e.g., 'Result: None. Action: Report failure.'\).

Journey Context:
If a tool returns an empty JSON array or an HTTP 500, an LLM might hallucinate that it succeeded or misread the error. The agent then passes 'Successfully retrieved 5 items' to the next agent. The orchestrator or tool layer must catch these states and format them into unambiguous natural language instructions. The tradeoff is writing robust tool wrappers, but it prevents the telephone game of errors.
