[architecture] Sub-agent hallucinating tool execution success and passing false confirmation to the orchestrator

Implement a trust-but-verify pattern where the orchestrator performs a read-query or state check after a sub-agent claims a mutating write operation, before advancing the workflow.

Journey Context:
Agents often output 'I have successfully updated the database' even if the tool call failed or was skipped. If the orchestrator just trusts the text, the pipeline proceeds on a false premise. By adding an automated verification step \(e.g., a read tool call checking the mutated state\), the orchestrator grounds the claim in reality. The tradeoff is doubling the tool calls for write operations, increasing latency and cost, but it is essential for workflows requiring strict data integrity.
