Sample/Example Custom Vocabulary & Tone

I was wondering if anyone would be willing to share their examples of custom vocabulary/tone? While I'm used to creating custom prompts for AI (for example in Perplexity), I'm wrestling with how best to apply this to cleft. Without adding anything to the custom field, it works fantastic (as I've said before I'm Clefts biggest fan! :) )! I'm just curious to test the customfeature and would love some suggetsions to mabye point me in the right direction. Thanks so much!
