Character Forking And Customization With Lightweight Editing

Unique: Implements character forking as a lightweight copy-and-modify operation on prompt definitions, enabling instant character variants without model retraining or infrastructure overhead, similar to GitHub's fork model but applied to AI personas

vs others: Faster iteration than fine-tuning-based character customization, but less flexible than programmatic prompt engineering; trades off control for accessibility
