At a minimum we need to be able to give copilot access to the working directory and files.
I think many developers would like it to have write access as well as just read.

It could help speed up tasks such as making new reports when there are existing reports for copilot to use as a template.
Create new files based on what's being discussed etc.

I might be trying to jump a couple of years with the write access, but there's no reason it shouldn't be able to read what is right in front of it.
