Bub

Bub it. Build it.

Bub is a coding agent CLI built on republic. It is designed for real engineering workflows where execution must be predictable, inspectable, and recoverable.

Four Things To Know

1. Command boundary is strict: only lines starting with , are treated as commands.
2. The same routing model is applied to both user input and assistant output.
3. Successful commands return directly; failed commands fall back to the model with structured context.
4. Session context is append-only tape with explicit anchor/handoff transitions.

Quick Start

cd bub
uv sync
cp env.example .env

Minimal .env:
