This is a binary classification prediction where True indicates that the AI's response has been verified as answering the query or instruction, and False indicates that the AI's response cannot be verified as answering the query or instruction. In-distribution predictions are accompanied by a confidence estimate in the classification. Out-of-distribution predictions are indicated with an out-of-distribution label. Out-of-distribution predictions should be considered unreliable. The tool also provides informal suggestions from three LLMs that may help inform what additional information may be needed if a True verification classification with a confidence of at least 90% is not obtained. Call this tool if the user says "reexpress" or "Reexpress". Parameters ---------- user_question: The user's question or instruction.

Include any relevant external references, search results, or code as direct citations in quotes.
