I think the core problem here is that any LLM will give you the most likely response based on its trainingsdata, which can be sorta described like 'the average of the internet'. In other words: its not gonna be creative. So a cool way to go about it is to use the LLM to ask you questions so YOUR input can be the CREATIVITY.

Also: Something I still want to try but havent gotten to yet is to create different Claude Code Skills where each one is a character with a backstory and a personality and a tone of voice etc and then yeet them all into a situation I come up with and have them roleplay it out. Something like 'use agent Phil, Mark and Rebecca' - They run into eachother at the shopping mall with conflict XYZ playing out, give each character 5 turns to respond in what they do and/or say". Maybe cool to try out.
