I am using the assistant, and it truly works incredibly. It perfectly runs the code and evaluates the needed changes (I only used Claude 4.6 Opus with High thinking enabled).
I was wondering if there is a way to limit the assistant's capabilities. I asked this to the assistant, but it said it would not access anything not needed, which is not very reassuring. For instance, only give writing permission but no reading permission, or only give permission to certain types of files (e.g. .R and .qmd but not .xlxs or .rds). I also think that upon installation, you should be able to select which folders it has access to.
R is widely used in medical statistics, and being able to ensure the safety of private data is really important.
