> Wired up Claude for response generation — The retrieved documents get passed as context to Anthropic Claude (claude-sonnet-4-6) along with a strict system prompt: answer only from the knowledge base, keep responses short and conversational, and if you don’t know — say so and offer to take a message. No hallucinations allowed.
