faces
Use this skill whenever someone wants to build an AI that thinks like, sounds like, or acts like a specific person. This includes: turning interviews, letters, videos, or documents into a chateable AI persona; creating customer personas or focus groups you can actually talk to (not just static profiles); replacing bloated SOUL.md / soul documents / system prompts with something more token-efficient; giving agents in a multi-agent system distinct personalities, behavioral modes, or points of view; creating a digital twin or memorial AI; comparing how different people think; composing new perspectives from existing ones; or sharing persona access via scoped API keys. Also trigger when the user mentions the Faces Platform, the `faces` CLI, cognitive primitives, mind arithmetic, or compile personality. Use even if Faces is not yet installed — the skill covers setup. Do NOT use for fine-tuning models, RAG/retrieval systems, creative writing (NPC backstories, fiction), or thematic analysis of transcripts.
