Karthik Nadig (@karthiknadig) the tagged issue was filed by you originally - any ideas that could help here?

This really need to be solved upstream. Essentially, one of the tools applies first, VS Code should synchronize the changes to all servers. This does not happen when using an import sorter. So the second tool sees the wrong version of the document.

Sam Duke (@samskiter) a workaround and a faster tool here is Ruff (ruff extension is available in the market place). It supports isort style import sorting and black style of formatting, and several linters in a single tool.

I'm seeing this with black and isort. Any workarounds available?

Neil Ferreira (@neilferreira) see #25538 (comment) for workaround

Sam Duke (@samskiter) as I mentioned in my comment. This can’t be fixed in extension the issue is microsoft/vscode#174295 . I created that issue when I noticed the problem when I created this extension. I don’t see any change we can do locally to address this. It should be addressed in VS Code.
