  1. Foundations of Role Based Prompting
    By defining roles as operating specs, we first need to understand the difference between "roles" and "roleplay" before we can tell AI who to be.
  2. Who / What / When / Where / Why
    Learn how to select the right role, experience, or place of work for AI. And where you should make sure to include it so AI follows it.
  3. Advanced Techniques
    How to avoid forcing hallucinations and a check on how many tokens are saved with a good role in prompts.
