Something I've been trying recently for non-throwaway code is extensive refactoring, without typing any code myself but by closely directing the coding agent.

Prompts like "move the code relating to SQL query analysis into a new file", "look for opportunities to use pytest parametrize to remove duplication in that test", "rename method X to Y".

Early indications are that this is helping a lot with the problem where it's easy to churn out thousands of lines of code and not really have it stick in my head, even if I review every line of it.

Reviewing code and actively refactoring it is less tedious and more mentally engaging than reviewing code without changes.

If this was a human collaborator I'd be worried that I'm just creating busywork for them, but I don't care about busywork for LLMs!

The goal is to produce code that I understand and that I can remember just well enough that I get an updated mental model to help me productively make future decisions about the codebase.

There’s a lot of overlap there with the sorts of things traditional automated refactoring tools can do approximately instantly, locally, and for free.

I think the best approach is active code review as the agent does small batches. Or letting it come up with a solution, testing if it passes or fails the desired outcome, then creating a separate fresh project and asking it to rewrite in small parts, and have it explain to you what and why it's doing to achieve each part.

Interesting idea.

It’s almost like a buffer space would be useful for code.

I’ve been using tuicr for agent code reviews and have been enjoying that. I think I’ll try your idea as part of my workflow.
