Working on Hostwarden

A Hostwarden checkout does one of two jobs, and the workspace decides which. Where memory/ is the workspace, the checkout administers servers — see Running Hostwarden. Without one, and in every git worktree, whatever its main checkout is, the session works on Hostwarden itself instead.

The development checkout​

A development checkout has no workspace. The session changes Hostwarden itself and reaches no server, not even the local machine. Every git worktree counts as development, whatever its main checkout is.

In Claude Code a hook announces the mode at session start and another enforces it. In development the first also puts a shim in front of ssh, scp, sudo, ansible, terraform and the rest on the PATH of every command the agent runs, so they refuse however they are started; git push still reaches the real ssh. Under WSL the shim also covers the Windows programs that reach a server or administer the machine: ssh.exe, wsl.exe, powershell.exe and the rest. Other tools follow the same rule from AGENTS.md.

The taboo guard in development​

The taboo guard knows the mode as well. In development it judges a command in full only when the command can reach past your own files — it names ssh, sudo, a container, VM or cloud tool — or when the session runs as root or in the disk group. Otherwise a commit message, a pull request title or a search that names mkfs or fdisk is text and goes through. SSH keys, sshd_config, diskutil and the Windows taboos stay guarded in every mode, and so does power off on a machine running systemd, which lets you power off without root.

Asking an operations session​

When development needs to know something about a live server, the agent hands the question to a session in your operations checkout — a message to one already running, or one command that starts it — and reads the answer. That session runs the access lists and the full first-connection pipeline as always, a one-line question included. Details: rules/server-check-handoff.md.
