Bhavik-Jikadara/ai-customer-service-agent ? reverse-engineered prompt

Build me a production ready AI customer support agent for an e commerce style business. It should handle things like order status checks, refund and return questions, inventory or product availability, and general support chats. I want it to keep track of the conversation so it feels natural across multiple messages, and it should be able to use tools for actions like looking up orders or processing refunds.

Please also add basic sentiment awareness, error handling, fallback responses, and a simple way to see performance reports and conversation summaries. Include a demo script, examples, tests, docs, and a clean setup flow with environment variables for the OpenAI key. Use current OpenAI docs online if you need to, and make it feel ready for real use, not just a toy chatbot.
