In this presentation, I will demonstrate how to avoid turning AI-agent development into an endless loop of chat corrections and bug fixes. The talk will break down how to structure chaotic "vibecoding" into a controlled engineering process where quality is driven by planning rather than luck. I will introduce agent-handling techniques from top industry minds and provide a quick overview of the essential toolkit: Skills, MCP, Hooks, and more.
You will learn about Spec-Driven Development, existing frameworks, and how they help solve tasks on the first try without losing context between agent sessions. I will explain the specifics of different approaches and help in choosing the right one. A major focus will be placed on how testing integrates into the vibecoding workflow: what to use instead of Playwright MCP (based on advice from Microsoft themselves) and what testing solutions exist for mobile development. All of this will be demonstrated in practice: throughout the talk, a complete project featuring Web, Android, iOS, and Backend will be built from scratch.
