I put your prompt into the vibe coding tool I'm working on (shameless plug).

The first version[0] looked good, but when I inspected it I found that it just picked an I Ching prediction at random on the back-end, instead of actually flipping coins.

I updated the prompt to the following:

Create app where you input a question, then flip coins to generate an I Ching prediction (client-side). First show the standard I Ching prediction and it's hexagram, and then use AI to generate a fortune analysis based on the prediction and your initial question.

And the result was much more laborious[1] of a UI :shrug:
