Hey, I’m Bheta Maranatha. I build systems powered by AI automation. In this video, I’ll walk you through how I built “Alicia,” an AI receptionist for Bistro Harmony Restaurant using the new OpenAI Agents SDK and Guardrails. This workflow shows you how to: ✅ Create a fully functional AI agent with GPT-4.1 ✅ Connect file search tools for restaurant data lookup ✅ Add moderation & safety layers using @openai/guardrails ✅ Automatically detect PII, toxic content, jailbreaks, or hallucinations ✅ Respond only to relevant restaurant queries and reject the rest politely ⚙️ Tech Stack: – OpenAI Agents SDK – Guardrails API – TypeScript / Node.js – GPT-4.1 Model – File Search Tool (Vector Store Integration) 🔥 Learn more about OpenAI AgentKit: 👉 https://openai.com/index/introducing-agentkit/ 📲 Follow me for more AI system builds: Instagram: @renatha_maranatha TikTok: @renatha_maranatha 💡 If you want to build safe, autonomous AI agents that actually handle real-world business workflows — this tutorial is for you.
