 Inspired by [Vivy: Fluorite Eye's Song](https://en.wikipedia.org/wiki/Vivy:_Fluorite_Eye%27s_Song): **Agent** — the executor/tool before self-awareness; **Diva** — the diva at the center of the stage. Agent Diva is the foundational piece of Project Vivy, an experimental platform toward an AI operating system.
