Can I vibe code Boost AI?

Build an enterprise-grade customer service chatbot API using Node.js, TypeScript, and Fastify.

1. DATA MODEL & STATE MANAGEMENT:
- Implement a Redis-backed session store tracking conversation history, state variables, user authenticated identity (Shopify customer ID), and active channel.
- Maintain audit logs in PostgreSQL for every turn: prompt, raw LLM completion, detected intent, tool executions, and latency.

2. CORE FUNCTIONALITY:
- Integrate OpenAI API (gpt-4o) using structured outputs via Zod schemas for intent classification: 'ORDER_STATUS', 'RETURN_REQUEST', 'POLICY_FAQ', 'AGENT_HANDOFF'.
- Implement a RAG pipeline over store policy documents using pgvector.
- Integrate with Shopify Admin REST/GraphQL API for authenticated actions: fetch order details by order number and email, issue return shipping labels for eligible items.
- Implement deterministic fallback: if confidence for intent or RAG context is below 0.75, immediately generate a payload for human agent takeover and emit a webhook to Gorgias/Zendesk.

3. PRIVACY & SECURITY:
- Add a redaction middleware scrubbing PII (credit cards, SSNs, passwords) before writing to logs or sending context to external LLMs.
- Require signed JWT tokens for embedded frontend widget communication.

4. FAILURE MODES & OUT OF SCOPE:
- If Shopify API rate limits or errors occur, return a clear graceful apology and auto-route ticket to human support.
- Out of scope for MVP: live voice processing and multi-language dynamic translation.
