It looks like this regex pattern, which has been copied to several locations, uses a now-invalid escape sequence. These should probably all be raw strings.

Was just going to fix this, but it looks like it's inside autogenerated API code? Unsure where exactly to find the actual contents

Thanks for raising @fennewald ! We'll take a look

I'm getting the same error on the first run after uv pip install cloudsmith-cli. The syntax warning is only raised when there was no bytecode compilation yet, so it isn't showing with pip or after the first run.
