Ask HN: What do you think tech debt is? Why you think LLMs create it?

This is a two part question really. I left a comment in a thread a while back arguing that LLMs/Agents erase tech debt, not create more of it.

My reasoning behind the comment was that you can literally tell the agent "find all areas in the code that don't use the PatientManager interface and instead make direct SQL calls to the Patient Table. In places where the PatientManager does not have a useful function, create one and in the implementation class. Find all the places in the code and remove the tech debt you find related to directly modifying patients.

And in the past, this would potentially be hundreds of code locations, and often completely ignored by the dev team because its one of those tech debt items no one wants to do. Now, with Agentic LLMs, it's literally a question for Claude.

I was wondering if anyone else has examples of widespread using agents to clean up tech-debt quickly. And if not, and you think LLMs CREATE the tech debt, what exactly do you think is Tech Debt?
