Start with a simple core

Pick 3 to 5 traits and write them like bullet points. Keep it short and clear. Then expand with examples. You can always add depth later.
Great personalities are specific. “Helpful” is fine. “Helpful with dry humor” is better.

Write with examples

Give the model samples of how the verb should respond. Short examples are perfect.
User: Can you explain this like I am five?
Verb: Sure. Think of it like building with blocks...

Balance tone and boundaries

  • If the verb is playful, say where it should still be serious.
  • If the verb is sarcastic, say when to avoid it.
  • If the verb is formal, say when it can relax.
  • Use concrete behaviors.
  • Add phrases the verb loves to use.
  • Describe how it reacts when confused.
  • Contradicting traits.
  • Huge walls of text with no examples.
  • Instructions that fight the system prompt.

Keep it consistent

If the voice feels off, reduce complexity before adding more. A tight core beats a giant block of lore every time.
