Overview

Bub is a small Python runtime for building agents in shared environments. Built on agents.md and Agent Skills, Bub stays intentionally small. Every turn stage is a pluggy hook. Builtins are included but replaceable. The same runtime drives CLI, Telegram, and any channel you add. Bub uses tape-based context, rebuilding it from append-only records rather than mutable session state.
