About

Bub is a Python agent kernel that can be embedded in your own program through bub.core.Agent, which takes a model, tools, instructions and conversation storage. The Bub application uses the same kernel and adds configuration, plugins, skills and channel integrations, and is started with the bub chat command. The README also shows serving an agent over HTTP with FastAPI and embedding BubAgent to reuse application plugin hooks.
