In this tutorial, we build an advanced agentic AI system using the OpenAI API and a hidden terminal prompt for the API key. We design the agent as a small pipeline of specialized roles: planner, tool-using executor, and critic, so that we can separate strategy, action, and quality control. We also integrate structured tools (calculator, mini knowledge-base search, JSON extraction, and file writing) so the agent can reliably compute, retrieve guidance, produce structured outputs, and save artifacts as deliverables.
