i made a random pool checker using chatGPT

i used chatgpt to make a prompt checker for random pools, it looks like it works but i haven't rested much. if anyone is interested i could share it. i did make it generate a test file for you to drop your prompts into if it doesn't find one. i don't rally know how dangerous that could be, but the file just says "drop your text here".

🔹 Step 1: Save the Script

1. Copy the full code I gave you.

2. Paste it into a text file.

3. Save it as, for example:

   comfy_prompt_checker.py

   
   you should be able to just run it to generate the file it will check, then drop your prompts in whenever you need to.
   after that it will check to find if there are any errors with any pools.
   next it will also give you the odds for each option in the pools.
   its not the best looking output but I don't really know how to python or code or anything but I wanted a tool to make sure things work out.
   
   this is a much better second release. 
   should help with comfyUI random pools and keeping everything in order.
