claude-hdb 16a4c129fc feat: 'claudebox doctor' — the host-health checks as a first-class verb
Every fault the drill's doctor diagnoses is a user's fault first: a
wedged Incus daemon, a dnsmasq that silently isn't serving, a VPN
resolver boxes inherit, isolation claimed by config but off in the
kernel — each has killed a cold mint or weakened a boundary, with a
cloud-init error that names none of them. The CLI half-admitted it:
cmd_new's failure path hand-pointed at issue #33, doing one special
case of a doctor's job inline.

The verb delegates to the installed drill/doctor.sh (the tree ships
whole) — one hardened script, two audiences. Its flags pass through;
the verdict now reads 'fit to mint boxes (and to drill)'; the mint-
failure hint ends with 'claudebox doctor' instead of the hand-rolled
diagnosis.

Closes #46

USAGE

COMMANDS
EOF
local r v sum
for r in "${CMDS[@]}"; do
IFS='^' read -r v _ _ sum _ _ <<<"$r"
printf ' %-9s %s\n' "$v" "$sum"
done
cat <<'EOF'
OPTIONS
--name <box> Name for the new box (new)
--from <src>[/<snap>] Clone from box <src>, or from its snapshot (new)
--vm Force VM mode: the trust-less target (new)
--container Force container mode: weaker isolation, (new)
dev/test only. Default where /dev/kvm is absent.
--json Emit Incus JSON instead of a table (list, info)
--force, -f Delete without the confirmation prompt (rm)
--remote <r> Act on Incus remote <r> (any)
--help, -h Help; after a command, help for that command
--version, -V Print the claudebox version
Options come after the command: 'claudebox list --json', not 'claudebox --json list'.
EXAMPLES
# mint a box and log in inside it — the tool never handles your token
claudebox new --name work
claudebox shell work # then: run 'claude', then /login
# log in once, reuse forever: checkpoint the authed box, clone from it
claudebox snapshot work authed
claudebox new --name feature --from work/authed
# what have I got, and what can I clone?
claudebox list
claudebox info work
# run something without opening a shell
claudebox exec work -- git -C project pull
# anything claudebox doesn't wrap: boxes are plain Incus instances
claudebox incus work -- config show
EXIT STATUS
0 ok
1 it went wrong (Incus failed, no such box, aborted at a prompt)
2 you asked wrong (unknown command, bad flag, destructive act without --force)
THE MODEL
A box carries NO credentials. You authenticate interactively inside it
('claude' then /login; 'gh auth login'); claudebox never stores or injects a
secret. A box reaches the public internet and nothing else — there is no
inbound path. Destroying a box loses nothing you didn't push.
claudebox owns a command when it must enforce something Incus cannot see: the
user.claudebox=1 boundary, the isolation stack, or the creds-free snapshot
workflow. Everything else is Incus's job — and 'claudebox incus' is the door.

new) cat <<'EOF'
Mint a box. Without --from, launches a fresh Debian 13 box from cloud-init
(~10 min cold) with Claude Code installed and NO credentials. With --from,
clones an existing box or one of its snapshots — Claude login, git creds and
clones carry over, isolation is preserved.
--name <box> Required. The box's name.
--from <src>[/<snap>] Clone src's live state, or its snapshot <snap>.
--vm | --container Force the mode. VM is the trust boundary and the
default wherever /dev/kvm exists; container mode
(security.nesting=true) is the fallback for hosts
without nested virt — weaker isolation, dev/test only.
claudebox new --name work
claudebox new --name feature --from work/authed
EOF
;;
list) cat <<'EOF'
List the boxes claudebox minted on this host: name, state, type, snapshot count.
Takes no box — for one box, that's 'claudebox info <box>'.
--json Incus's JSON, straight through, for scripting.
claudebox list
EOF
;;
info) cat <<'EOF'
Show one box: state, type, IP address, and — the reason this exists — the
labels of its snapshots, with the --from line to clone one.
--json Incus's JSON, straight through, for scripting.
claudebox info work
EOF
;;
shell) cat <<'EOF'
Open an interactive shell in a running box as the 'claude' user. This is the
only entry path — there is no SSH and no inbound route to a box.
claudebox shell work
EOF
;;
exec) cat <<'EOF'
Run a command inside a box as the 'claude' user. Everything after -- is passed
through untouched; the -- is required, or claudebox will read your command's
flags as its own.
claudebox exec work -- git -C project pull
claudebox exec work -- claude --version
EOF
;;
snapshot) cat <<'EOF'
Checkpoint a box. Snapshots are how an authenticated box is reused: log in
once, snapshot, then 'new --from <box>/<label>' as often as you like. The
label defaults to manual-<epoch>; 'claudebox info <box>' shows the labels you
have.
claudebox snapshot work authed
EOF
;;
restore) cat <<'EOF'
Roll a box back to one of its snapshots, in place. Anything in the box since
that snapshot is lost. 'claudebox info <box>' lists the labels.
claudebox restore work authed
EOF
;;
rename) cat <<'EOF'
Rename a box. Incus cannot rename a running instance, so stop it first:
claudebox down work
claudebox rename work archive
claudebox start archive
Snapshots and Claude auth follow the box; anything referring to the old name by
hand (a --from line, a script) does not.
EOF
;;
rm) cat <<'EOF'
Delete a box and every snapshot it has. This cannot be undone, so it asks for
confirmation first; --force (-f) skips the prompt. With no TTY to confirm on
(a script, a pipe), it refuses unless --force is given.
claudebox rm work
claudebox rm work --force
EOF
;;
incus) cat <<'EOF'
The door out. claudebox wraps the box lifecycle and the isolation model, not
all of Incus — so when you need something it doesn't wrap, run Incus through
here and keep the safety rail that matters: the box name is resolved and
checked against the user.claudebox=1 tag, so you cannot aim it at an instance
claudebox didn't mint.
Everything after -- is passed to incus verbatim. A literal {} is replaced with
the resolved instance name; with no {}, the instance is appended at the end.
The command that will run is echoed before it runs.
claudebox incus work -- config show
claudebox incus work -- config device add {} extra disk source=/data path=/data
Changing the profile, the network, a device or a security.* key can take a box
outside the isolation stack. claudebox warns and then does as you asked — from
there, the trust boundary is yours to keep.
EOF
;;
doctor) cat <<'EOF'
Answer "is this host fit to mint boxes?" from ground truth, not config claims:
is the Incus daemon answering, is a dnsmasq actually serving claudenet, does
the kernel's bridge port say 'isolated on', is the resolver pinned or is a
host VPN's DNS leaking into boxes, can a box actually resolve names. Every
check exists because its fault has happened — most kill a cold mint with a
cloud-init error that names none of them.
--fix also revert what a drill run may have left behind
--pin-dns pin claudenet's resolver to public upstreams and re-test
(setup-host.sh now pins by default; this is the quick test)
claudebox doctor
claudebox doctor --fix
Exit 0 = clean; 1 = problems found (each printed with its fix). Read-only
unless --fix or --pin-dns is given.
EOF
;;
status) cat <<'EOF'
Deprecated alias for 'claudebox list'. It ignored the <box> argument it
advertised, so it was split into 'list' (all boxes) and 'info <box>' (one). It
still works, and forwards to 'list'.
EOF
