Boxes with bx

bx starts Boat sandboxes ("boxes") from saved snapshots and saves each one as a herdr machine labelled with the box name. bx --help and herdr --skill are the references. This skill is the procedure. To move the current Claude Code session itself to a box, use bx-teleport.

1. Pick the snapshot

Run bx list. It prints each snapshot and the repos baked into it.

Is the repo you need in a snapshot's REPOS column?
├── Yes → that snapshot. The repo is at ~/<snapshot>/<repo>, deps installed, at the bake's commit.
└── No  → dev, then clone the repo on the box with `gh repo clone`.

A snapshot saves the clone and pnpm install (about a minute per box). Never bake a new snapshot for a one-off task: a bake takes 15 minutes.
