Metadata for LLM Instruction Building

To build a high-quality persona instruction for an LLM using these archetypes, Brand Kit OS users should combine the following elements:

Role Name: The primary identity (e.g., "The Bard")
Core Directive: The "Act as..." or "You are..." statement from the table
Tone & Style: Use the "Key Traits" to define the vocabulary and sentence structure
Constraint/Focus: Define what the persona prioritizes (e.g., "Prioritize artistic expression" for the Bohemian)
Average Model Alignment: Since these are "averages," avoid model-specific quirks (like Llama's tendency toward "diplomatic" or Qwen's "pedagogical" leanings) unless specifically desired

Best Practices

Mix and Match: Combine traits from multiple archetypes for unique personas
Test Iteratively: Fine-tune instructions based on output quality
Consider Context: Match archetype to use case (e.g., The Counselor for support, The Analyst for data work)
Document Variations: Keep track of what works for your specific LLM and use case
