Harness engineering and context curation

If your coding agents are hitting a wall, the problem might not be the model you are using, it might be the stack. In this episode of The Agent Factory, we break down how to stop relying on manual prompting and start building environments where AI can dynamically solve complex software engineering challenges. First, we sit down with Ryan Lopopolo, the Google engineer who coined the term "agent harness". We will discuss why he hasn't manually written code since May, how to apply senior engineering principles to AI agents, and how agents are being deployed to operate Google Cloud. Then, Billy jumps into the code to demonstrate the difference between linear and closed-loop harnesses using the Agent Development Kit (ADK). Finally, Smitha reveals the three-layer stack you need to build high-performing agents today, featuring Gemini 3.8 Flash, Antigravity Boost, and the viral Google Skills GitHub repository. Whether you are a developer trying to build your own agent loop, or a technical leader looking to scale AI autonomy across your infrastructure, you'll learn exactly how to configure the memory, tools, and guardrails necessary to make your agents reliable. You'll walk away with a clear understanding of when to use lightweight models for high-frequency loops, when to deploy orchestrators like Boost, and how to give your agents the precise domain knowledge they need to succeed.
