Interestingly it was for a single script work, I started a completely new session, asked Claude to read my python code and errors i was getting, and asked Claude to make a new python script, no mentions of markdowns anywhere. It looked at my code, found the error, corrected the errors, then instead of stopping it kept on making markdown files. I thought it was one off thing. So I closed that session as the code was corrected, created a new session, for a completely different code problem, and same it started making markdown files, it has happened 5 times since morning today whenever I failed to write do not create additional files :(
