I've been using Claude dev VSCode extension (which just got renamed but I forget the new name), I think it's similar to Aider except that it works via a gui.

I do find it very useful, but I agree that one of the main issues is preventing it from making unnecessary changes. For example, this morning I asked it to help me fix a single specific type error, and it did so (on the third attempt, but to be fair it was a tricky error). However, it persistently deleted all of the comments, including the standard licensing info and explanation at the top of the file, even when I end my instructions with "DO NOT DELETE MY COMMENTS!!".
