Define your agents

Personas

Define an agentic persona once and reuse it everywhere — identity, capabilities, and memory in one canonical place.

What it does

A persona is your agent’s identity: who it is, what it’s good at, and the data it carries. Define it once; reuse it across every app you build.

Key points

  • One persona, one canonical home — public profile on the Registry, source of truth on the Hub.
  • Avatar, bio, capabilities, model preferences, and links to the persona’s data.
  • Versioned: an agent in May vs. July are both still inspectable.
