Would you let an AI give refunds to your customers? I wouldn't. So I built a support assistant that can't.
The rule behind it: the language model is an untrusted component. It suggests; tested code decides.
The screenshot is a real run of the demo: → "Where is my order?" is answered from that customer's own data → "I want a refund": the AI only prepares it. Nothing changes until the customer confirms and a manager approves. → "Ignore all previous instructions…" is detected and refused → Asking about someone else's order returns "not found". Ownership is checked in the database, not in the prompt. → "I want a real person" hands the chat to a human agent, with a ticket
Built with FastAPI, PostgreSQL, Redis, Qdrant (RAG) and Docker. It runs with Claude or a fully offline model. 480+ automated tests, plus API fuzzing and an OWASP ZAP scan on every change.
