How do you prevent an LLM from hallucinating or making incorrect write actions (like deleting/voiding transactions) in QuickBooks?

One member's approach: when the LLM (agent) analyzes something like a deferred revenue account and determines what corrective actions are needed, it does not directly execute those actions. Instead, the LLM writes its proposed actions to a 'staging table' in a database on the server. A separate script then retrieves the staged actions and displays them to the user. Only after the user clicks a 'confirm' button does another script execute the actions - at that point the LLM is no longer involved at all. This removes the LLM from the actual execution step, eliminating the risk of hallucination between what it proposed and what actually happens, which was described as a significant concern especially for actions like voiding or deleting entries where an overly broad action could cause unintended damage.
