bubbuild/bub

Bub it. Build it. A hook-first runtime for agents that live alongside people.

About the project

bubbuild/bub is a small Python runtime for building AI agents that work in shared environments such as conversations with people. It provides a hook-based turn pipeline and runs agents across command-line, Telegram, and other channels, with built-in tools, skills, and model execution; the catalogue entries extend or configure that workflow.
