This is the time to define your zen gardening style with formal tools.

You know just the way you like it, right?

Create an .editorconfig that describes the style, create linters and AST parsers that define your style in a concrete way. (You can actually create these with AI from your existing codebase btw =P)

Then when the AI comes in, it has to use those tools to confirm whatever it produces conforms to the zen garden style you've defined. It's just tools in a loop. Give it the tools to determine what it did is up to par and it will do it.

Peace and harmony for all.
