HEXACO psychometrics plus dual-process chat is ambitious avatar infrastructure.

Strengths
  • HEXACO personality model with live drift is more rigorous than typical trait systems
  • MCP integration for Cursor means avatars can actually interact with dev workflows
  • 49 passing tests and Soul Studio GUI shows real implementation beyond concept
Weaknesses
  • Feature accumulation feels like checklist — personality, memory, MCP, dual-process all at once
  • AI avatar runtime is crowded space with Character.ai, Replika, and countless agents
