Lesson 18: Secure, Professional Vibe Coding and the Final Project

An AI coding agent can build a feature that appears successful while placing an API key in source code, installing an unnecessary package, obeying malicious web content and preparing unsafe production settings. This creates a central question: when is AI-generated software secure and verified enough for responsible acceptance or deployment? Functional success is not the same as trustworthy release readiness. Security must therefore accompany the whole development lifecycle, rather than being added as a final check.
