You are building a customer-support agent in Azure AI Foundry Agent Service for an insurance company. The agent must handle policy questions but must never provide legal advice, must always escalate coverage disputes to a human, and must respond only in the customer's language. During testing, the agent occasionally offers interpretations of legal liability and answers in English regardless of the customer's language. You need to correct this behavior with the least engineering effort while keeping the guidance consistent across all conversations. What should you do?
