Agents are powerful—but without feedback, they're flying blind. In this talk, we’ll walk through how to build self-improving agents by closing the loop with evaluation, experimentation, tracing, and prompt optimization. You’ll learn how to capture the right telemetry, run meaningful tests, and apply insights in a way that actually improves performance over time. Whether you’re building copilots, chatbots, or autonomous workflows, this session will give you the practical tools and architecture patterns you need to make your agents smarter—automatically.
