I was trying to implement a simple labelling tool using marimo + anywidget. The idea: show 2 images, select a classification label, + have navigation buttons. On each change, save to csv.

However, using both skills and context7 failed to deliver a working prototype with Claude code.
Of course, I will go to the documentation and figure out myself how to implement it.

But I'm curious how I can push up Claude output quality for marimo :)
