bub

Bub is a minimal Python runtime designed for building agents in shared environments. Originally intended for group chats, it enables multiple users and agents to collaborate within the same conversation without hiding state or relying on framework-specific magic. Bub supports plugin extensions, where each stage acts as a plugin hook that can replace built-in functionality. The same runtime can operate across CLI, Telegram, and other custom channels. Bub's design allows context to be reconstructed from appended logs rather than being carried as mutable session state, making it easier to inspect, replay, and hand over.
