What the Claude Agent SDK Is and Why Engineers Build Their Own Harnesses
Udacity Blog
EDITOR BRIEF
The excerpt explains that every Claude experience runs through a harness, which is the software layer around the model. It says users already rely on harnesses in Claude products, but engineers often build their own when creating production AI systems.
INSIGHTS
For learners, this shows that using an AI model is only part of the job; the wrapper around it matters too. A useful next step is to build a simple harness that sends prompts, handles responses, and adds basic safety checks.
