What is an Agent Harness? (And How We Built One)

You don't need the best model to build a great agent—you need a model-driven harness that gets better every time the model does. Learn what agent harnesses are, why they matter, and how to build one using the Strands Agents Framework.We will walk you through a real-world example: building an agent that monitors the OpenAI changelog, classifies updates, searches for duplicate GitHub issues, and automatically files new issues when needed. Perfect for developers who've built a basic agent and want to future-proof it as models evolve.
