If I tell you to “fix the style issues”, then run golangci-lint run --fix ./... unless otherwise directed and fix all the resulting errors.
Do not run any commands other than golangci-lint by default. Again, unless the user told you to, don‘t be creative and look for TODOs or shell scripts or whatever. It’s just about the Go code. And the issues reported by golangci-lint. Unless the user tells you otherwise. Okay.
If there are too many errors in the entire tree (like more than 1000 or so) and it is making the resulting diff too big for a human to reasonably review, tell the user that there are a lot of style issues and ask them what to do.
