Ah, that's fair. Didn't think of code that couldn't be changed.

TrainedMonkey • Aug 21, 2025 • View on HN

It has a strong preference to only change pieces of code you asked it to touch.

heavenlyblue • Nov 22, 2018 • View on HN

I did not imply you can change the codebase, by the way.

Wouldn't the AI that wrote the original code be in a better position to modify it too?

sizzle • Jun 20, 2018 • View on HN

Couldn't they just reweite the code after leatving your solution?

webmobdev • Sep 27, 2021 • View on HN

That makes sense - I didn't consider that you may want to change the code yourself.

labster • Nov 8, 2017 • View on HN

It's a code revision, not an article. If you're a programmer the change is super obvious.

RedMist • Aug 29, 2025 • View on HN

No, making edits to an exiting codebase.(If that's what you meant)

Until it can change existing code, I think we're ok.

I agree but it's hard to change tack on older code based without confusing things further
