Claude Code Fixed One Bug and Introduced Two More

The author asked Claude Code to look into a Python script that sometimes skipped files. The service suggested a fix: the code looked cleaner, the explanation seemed convincing, and the original problem appeared to be solved.

After the script was run again, some files were processed twice, and an empty input folder triggered a separate error. The author writes that this case made them look at AI-assisted programming differently.
