Beyond Building Agents: Why Harness Design and Optimisation Matter
Building an AI agent is only the first step. A real agent needs a strong harness around it — the system that controls how the agent thinks, uses tools, manages memory, handles errors, tracks cost, and responds safely.
Without a good harness, even a powerful model can become expensive, slow, unreliable, or difficult to debug. This is why agent optimisation is so important.
In this session, we will explore how to design agents that are not just smart, but also practical for real-world use. We will look at how to reduce token usage, choose the right model for the right task, improve tool calling, manage context, add evaluation checks, and monitor cost before deploying agents into production.
The goal is to help developers move from “I built an agent” to “I built an agent that is reliable, efficient, and ready to use.”
