Did you do anything special? I tried this with just copy and paste with GPT-4o and it was absolutely terrible at it. It usually ended up spamming help in a loop and trying commands that didn't exist.

I have my own agent loop that I wrote, and I gave it a tool which it uses to send input to the parser. I also had a step which took the previous output and generated an image for it. It was just a toy, but it was pretty fun.
