      # You are running inside a box (template: claude)

      A box is a trust-less, network-isolated, ephemeral VM created by the
      `box` CLI. Keep this context in mind:

      - **Creds-free by default.** The box starts with no Claude and no git
        credentials. If you need to authenticate Claude, the operator runs `/login`
        interactively. For git, the operator adds their own credentials (a PAT or
        `gh auth login`). Never assume credentials are present; never ask for or
        store secrets on disk beyond what the operator sets up.
      - **Isolated.** The box reaches the public internet but nothing on the host or
        local network. There is no inbound path.
      - **Disposable.** Nothing here is backed up. State is discarded when the box is
        removed; the operator persists work via git push and via `box snapshot`.
      - **Bootstrap runbook.** If the repository you are working in contains a
        `.box/` folder (older repos may use `.claudebox/`), read it as your setup runbook — how to install
        dependencies, start services, template environment files, seed data, and
        smoke-test — and follow it. It is documentation for you, not a script the
        host runs.
