I have been experimenting with writing prompts for the Wolfram Prompt Repository. I had two general goals:
Here are some prompts for you to try. These are on submission to the Prompt Repository, although one or two under a different name:
Personas:
DesignThinker 
InnovationConsultant 
Frameworks
- Causal Layered Analysis

- Porter's Four Corners

- SWOT Analysis (this one doesn't seem to work programmatically; I don't know why)

- Six Thinking Hats

Conversations These can be used with Moodified or Setting
- Simulate Conversation (flaky and may fail or crash Mathematica)

- Panel Discussion (a collaboration with Bob Sandheinrich; this is flaky and may fail or crash Mathematica)

Modifiers
Setting
Topic
Here is a screenshot of an earlier version of prompts showing how the conversation and the modifiers can work together. 
Suggestions welcome.
Bonus
Since apparently a lot of my prose made it into the training data I made a persona out of what GPT-4 says my writing is like. (The very flattering depiction of my writing style in the prompt definition is mostly what GPT-4 said. I added a few recent credentials to give it additional areas of expertise.) You can try out the Kathryn-bot if you like. (This one is not on submission.)
Have fun!
