Volumes & state

Cache volumes (node_modules, …) are disposable. State volumes (.claude, …) hold the agent’s login and history, per project, and survive rebuilds. Machine volumes let you share volumes between different byre boxes. byre never reads or copies host credentials; nothing crosses unless you enable it, and what you enable, byre status shows.

By default agents log in once per project, inside the box, and maintain their own context. See How do I…? for enabling shared LLM credentials.
