Crabbox
Use Crabbox when OpenClaw needs remote Linux proof for broad tests, CI-parity
checks, secrets, hosted services, Docker/E2E/package lanes, warmed reusable
boxes, sync timing, logs/results, cache inspection, or lease cleanup.
Default backend: blacksmith-testbox. The separate blacksmith-testbox skill
has been removed; this skill owns both the normal Crabbox path and the direct
Blacksmith fallback playbook.
First Checks
- Run from the repo root. Crabbox sync mirrors the current checkout.
- Check the wrapper and providers before remote work:
command -v crabbox
../crabbox/bin/crabbox --version
pnpm crabbox:run -- --help | sed -n '1,120p'
../crabbox/bin/crabbox desktop launch --help
../crabbox/bin/crabbox webvnc --help
- OpenClaw scripts prefer
../crabbox/bin/crabbox when present. The user PATH
shim can be stale.
- Check
.crabbox.yaml for repo defaults, but override provider explicitly.
Even if config still says AWS, maintainer validation should normally pass
--provider blacksmith-testbox.
- If a warm direct-provider lease smells stale, retry with
--full-resync
(alias --fresh-sync) before replacing the lease. This resets the remote
workdir, skips the fingerprint fast path, reseeds Git when possible, and
uploads the checkout from scratch.
- For live/provider bugs, use the configured secret workflow before downgrading
to mocks. Copy only the exact needed key into the remote process environment
for that one command. Do not print it, do not sync it as a repo file, and do
not leave it in remote shell history or logs. If no secret-safe injection path
is available, say true live provider auth is blocked instead of silently using
a fake key.
- Prefer local targeted tests for tight edit loops. Broad gates belong remote.
- Do not treat inherited shell env as operator intent. In particular,
OPENCLAW_LOCAL_CHECK_MODE=throttled from the local shell is not permission
to move broad pnpm check:changed, pnpm test:changed, full pnpm test, or
lint/typecheck fan-out onto the laptop.
- Only use
OPENCLAW_LOCAL_CHECK_MODE=throttled|full when the user explicitly
asks for local proof in the current task. If Testbox is queued or capacity is
constrained, report the blocker and keep only targeted local edit-loop checks
running.
macOS And Windows Targets
Use these only when the task needs an existing non-Linux host. OpenClaw broad
validation still defaults to blacksmith-testbox.
Crabbox supports static SSH targets:
../crabbox/bin/crabbox run --provider ssh --target macos --static-host mac-studio.local -- xcodebuild test
../crabbox/bin/crabbox run --provider ssh --target windows --windows-mode normal --static-host win-dev.local -- pwsh -NoProfile -Command "dotnet test"
../crabbox/bin/crabbox run --provider ssh --target windows --windows-mode wsl2 --static-host win-dev.local -- pnpm test
target=macos and target=windows --windows-mode wsl2 use the POSIX SSH,
bash, Git, rsync, and tar contract.
- Native Windows uses OpenSSH, PowerShell, Git, and tar; sync is manifest tar
archive transfer into
static.workRoot. Direct native Windows runs support
--script*, --env-from-profile, --preflight, and PowerShell --shell.
crabbox actions hydrate/register are Linux-only today; use plain
crabbox run loops for static macOS and Windows hosts.
- Live proof needs a reachable, operator-managed SSH host. Without one, verify
with
../crabbox/bin/crabbox run --help, config/flag tests, and the Crabbox
Go test suite.
Default Blacksmith Backend
Use this for pnpm check, pnpm check:changed, pnpm test,
pnpm test:changed, Docker/E2E/live/package gates, or anything likely to fan
out across many Vitest projects.

Read the JSON summary. Useful fields:
provider: should be blacksmith-testbox
leaseId: tbx_...
syncDelegated: should be true
commandPhases: populated when the command prints CRABBOX_PHASE:<name>
commandMs / totalMs
exitCode
Crabbox should stop one-shot Blacksmith Testboxes automatically after the run.
Verify cleanup when a run fails, is interrupted, or the command output is
unclear:
blacksmith testbox list
Observability Flags
Use these on debugging runs before inventing ad hoc logging:
--preflight: prints run context, workspace mode, SSH target, remote user/cwd,
and target-specific tool probes. Defaults cover git, tar, node, npm,
corepack, pnpm, yarn, bun, docker, plus POSIX
sudo/apt/bubblewrap and native Windows
powershell/execution_policy/longpaths/temp/pwsh. Add
--preflight-tools node,bun,docker, CRABBOX_PREFLIGHT_TOOLS, or repo
run.preflightTools to replace the list. default expands built-ins; none
prints only the workspace summary. Preflight is diagnostic only; install
toolchains through Actions hydration, images, devcontainer/Nix/mise/asdf, or
the run script. On blacksmith-testbox, this prints a delegated-unsupported
note because the workflow owns setup.
CRABBOX_ENV_ALLOW=NAME,...: forwards only listed local env vars for direct
providers and prints set len=N secret=true style summaries. On
blacksmith-testbox, env forwarding is unsupported; put secrets in the
Testbox workflow instead.
--env-from-profile <file> plus --allow-env NAME: loads simple
export NAME=value / NAME=value lines from a local profile without
executing it, then forwards only allowlisted names. --allow-env is
repeatable and comma-separated. Profile values override ambient allowlisted
env values for that run. Direct POSIX, WSL2, and native Windows runs are
supported; delegated providers are not. Crabbox probes the uploaded profile
remotely and prints redacted presence/length metadata before the command.
--env-helper <name>: with --env-from-profile on POSIX SSH targets,
persists .crabbox/env/<name> and .crabbox/env/<name>.env so follow-up
commands on the same lease can run through ./.crabbox/env/<name> <command>.
Use only on leases you control; the profile stays until cleanup, lease reset,
or --full-resync.
--script <file> / : upload a local script into
and execute it on the remote box. Shebang scripts execute
directly on POSIX; scripts without a shebang run through . Native
Windows uploads run through Windows PowerShell, and Crabbox appends
when needed. Arguments after become script args.
Live-provider debug template for direct AWS/Hetzner leases:
mkdir -p .crabbox/logs
pnpm crabbox:run -- --provider aws \
--preflight \
--allow-env OPENAI_API_KEY,OPENAI_BASE_URL \
--timing-json \
--capture-stdout .crabbox/logs/live-provider.stdout.log \
--capture-stderr .crabbox/logs/live-provider.stderr.log \
--capture-on-fail \
--shell -- \
"echo CRABBOX_PHASE:install; pnpm install --frozen-lockfile; echo CRABBOX_PHASE:test; pnpm test:live"
Do not pass --capture-*, --download, --checksum, --force-sync-large, or
--sync-only to delegated providers. Also do not pass --script*,
--fresh-pr, --full-resync, or --env-helper there. Crabbox rejects these
because the provider owns sync or command transport. --keep-on-failure is OK
for delegated one-shots when you need to inspect a failed lease.
Efficient Bug E2E Verification
Use the smallest Crabbox lane that proves the reported user path, not just the
touched code. Aim for one after-fix E2E proof before commenting, closing, or
opening a PR for a user-visible bug.
Pick the lane by symptom:
- Docker/setup/install bug: build a package tarball and run the matching
scripts/e2e/*-docker.sh or package script. This proves npm packaging,
install paths, runtime deps, config writes, and container behavior.
- Provider/model/auth bug: prefer true live E2E. Use the configured secret
workflow, then inject the single needed key into Crabbox if needed. Scrub
unrelated provider env vars in the child command so interactive defaults do
not drift to another provider. If only a dummy key is used, label the proof
narrowly, e.g. "UI/install path only; live provider auth not exercised."
- Channel delivery bug: use the channel Docker/live lane when available; include
setup, config, gateway start, send/receive or agent-turn proof, and redacted
logs.
- Gateway/session/tool bug: prefer an end-to-end CLI or Gateway RPC command that
creates real state and inspects the resulting files/API output.
- Pure parser/config bug: targeted tests may be enough, but still run a
Crabbox command when OS, package, Docker, secrets, or service lifecycle could
change behavior.
Efficient flow:
- Reproduce or prove the pre-fix symptom when feasible. If the issue cannot be
reproduced, capture the exact command and observed behavior instead.
- Patch locally and run narrow local tests for edit speed.
- Run one Crabbox E2E command that starts from the user-facing entrypoint:
package install, Docker setup, onboarding, channel add, gateway start, or
agent turn as appropriate.
- Record proof as: Testbox id, command, environment shape, redacted secret
source, and copied success/failure output.
- If the issue says "cannot reproduce", ask for the missing config/log fields
that would distinguish the tested path from the reporter's path.
Keep it efficient:
- Reuse existing E2E scripts and helper assertions before writing ad hoc shell.
- Use
--script <file> or --script-stdin for multi-line E2E commands instead
of quote-heavy --shell strings on direct SSH providers.
- Use
--fresh-pr <pr> when validating an upstream PR in isolation from the
local dirty tree. Add --apply-local-patch only when testing a local fixup on
top of that PR.
- Use
--full-resync before replacing a warmed direct-provider lease when the
remote workdir or sync fingerprint appears stale.
- Use one-shot Crabbox for a single proof; use a reusable Testbox only when
several commands must share built images, installed packages, or live state.
- Prefer
OPENCLAW_CURRENT_PACKAGE_TGZ with Docker/package lanes when testing a
candidate tarball; prefer the repo's package helper instead of direct source
execution when the bug might be packaging/install related.
- Keep secrets redacted. It is fine to report key presence, source, and length;
never print secret values.
- Include
--timing-json on broad or flaky runs when command duration or sync
behavior matters.
Before/after PR proof on delegated Testbox:
- For PRs that should prove "broken before, fixed after", compare base and PR
on the same Testbox when practical. Fetch both refs, create detached temp
worktrees under
/tmp, install in each, then run the same harness twice.
- Do not checkout base/PR refs in the synced repo root. Delegated Testbox sync
may leave the root dirty with local files;
git checkout can abort or mix
proof state.
- Temp harness files under
/tmp do not resolve repo packages by default. Put
the harness inside the worktree, or in ESM use
createRequire(path.join(process.cwd(), "package.json")) before requiring
workspace deps such as @lydell/node-pty.
- For full-screen TUI/CLI bugs, a PTY harness is stronger than helper-only
assertions. Use a real PTY, wait for visible lifecycle markers, send input,
then send control keys and assert process exit/stuck behavior.
- When validating a rebased local branch before push, remember delegated sync
usually validates synced file content on a detached dirty checkout, not a
remote commit object. Record the local head SHA, changed files, Testbox id,
and final success markers; after pushing, ensure the pushed SHA has the same
file content.
- If GitHub CI is still queued but the exact changed content passed Testbox
pnpm check:changed, pnpm check:test-types, and the real E2E proof, it is
reasonable to merge once required checks allow it. Note any still-running
unrelated shards in the proof comment instead of waiting forever.
Interactive CLI/onboarding:
- For full-screen or prompt-heavy CLI flows, run the target command inside tmux
on the Crabbox and drive it with
tmux send-keys; capture proof with
tmux capture-pane, redacted through sed.
- Prefer deterministic arrow navigation over search typing for Clack-style
searchable selects. Raw
send-keys -l openai may not trigger filtering in a
tmux pane; inspect option order locally or on-box and send exact Down/Enter
sequences.
- Isolate mutable state with
OPENCLAW_STATE_DIR=$(mktemp -d). Plugin npm
installs live under that state dir (npm/node_modules/...), not under
OPENCLAW_CONFIG_DIR. Verify downloads by checking the state dir, package
lock, and installed package metadata.
- To test automatic setup installs against local package artifacts, use
OPENCLAW_ALLOW_PLUGIN_INSTALL_OVERRIDES=1 plus
OPENCLAW_PLUGIN_INSTALL_OVERRIDES='{"plugin-id":"npm-pack:/tmp/plugin.tgz"}'.
Pack with npm pack, set an isolated OPENCLAW_STATE_DIR, and verify the
package under npm/node_modules. Overrides are test-only and must not be
treated as official/trusted-source installs.
- For OpenAI/Codex onboarding proof, the useful markers are the UI line
Installed Codex plugin, npm/node_modules/@openclaw/codex, and the
package-lock entry showing the bundled @openai/codex dependency. A dummy
OpenAI-shaped key can prove only UI/install behavior; it is not live auth.
Reuse And Keepalive
For most Blacksmith-backed Crabbox calls, one-shot is enough. Use reuse only
when you need multiple manual commands on the same hydrated box.
If Crabbox returns a reusable id or you intentionally keep a lease:
pnpm crabbox:run -- --provider blacksmith-testbox --id <tbx_id> --no-sync --timing-json --shell -- "pnpm test <path>"
Stop boxes you created before handoff:
pnpm crabbox:stop -- <id-or-slug>
blacksmith testbox stop --id <tbx_id>
Interactive Desktop And WebVNC
Prefer WebVNC for human inspection because the browser portal can preload the
lease VNC password and avoids a native VNC client's copy/paste/password dance.
Use native crabbox vnc only when WebVNC is unavailable, the browser portal is
broken, or the user explicitly wants a local VNC client.
Common desktop flow:
../crabbox/bin/crabbox warmup --provider hetzner --desktop --browser --class standard --idle-timeout 60m --ttl 240m
../crabbox/bin/crabbox desktop launch --provider hetzner --id <cbx_id-or-slug> --browser --url https://example.com --webvnc --open
Useful WebVNC commands:
../crabbox/bin/crabbox webvnc --provider hetzner --id <cbx_id-or-slug> --open
../crabbox/bin/crabbox webvnc daemon start --provider hetzner --id <cbx_id-or-slug> --open
../crabbox/bin/crabbox webvnc daemon status --provider hetzner --id <cbx_id-or-slug>
../crabbox/bin/crabbox webvnc daemon stop --provider hetzner --id <cbx_id-or-slug>
../crabbox/bin/crabbox webvnc status --provider hetzner --id <cbx_id-or-slug>
../crabbox/bin/crabbox webvnc reset --provider hetzner --id <cbx_id-or-slug> --open
../crabbox/bin/crabbox desktop doctor --provider hetzner --id <cbx_id-or-slug>
../crabbox/bin/crabbox desktop click --provider hetzner --id <cbx_id-or-slug> --x 640 --y 420
../crabbox/bin/crabbox desktop paste --provider hetzner --id <cbx_id-or-slug> --text "user@example.com"
../crabbox/bin/crabbox desktop key --provider hetzner --id <cbx_id-or-slug> ctrl+l
../crabbox/bin/crabbox artifacts collect --id <cbx_id-or-slug> --all --output artifacts/<slug>
../crabbox/bin/crabbox artifacts publish --dir artifacts/<slug> --pr <number>
desktop launch --webvnc --open is usually the nicest one-shot: it starts the
browser/app inside the visible session, bridges the lease into the authenticated
WebVNC portal, and opens the portal. Keep browsers windowed for human QA; use
--fullscreen only for capture/video workflows.
If Crabbox Fails
Keep the fallback narrow. First decide whether the failure is Crabbox itself,
Blacksmith/Testbox, repo hydration, sync, or the test command.
Fast checks:
command -v crabbox
../crabbox/bin/crabbox --version
crabbox run --provider blacksmith-testbox --help | sed -n '1,140p'
command -v blacksmith
blacksmith --version
blacksmith testbox list
Common Crabbox-only failures:
- Provider missing or old CLI: use
../crabbox/bin/crabbox from the sibling
repo, or update/install Crabbox before retrying.
- Bad local config: pass
--provider blacksmith-testbox plus explicit
--blacksmith-* flags instead of relying on .crabbox.yaml.
- Slug/claim confusion: use the raw
tbx_... id, or run one-shot without
--id.
- Sync/timing bug: add
--debug --timing-json; capture the final JSON and the
printed Actions URL. Large sync warnings now include top source directories
by file count and a hint to update .crabboxignore / sync.exclude; inspect
those before reaching for --force-sync-large. Quiet rsync watchdogs and SSH
timeouts now print next_action= hints; follow them, usually --full-resync
first and a fresh lease second.
- Cleanup uncertainty: run
blacksmith testbox list and stop only boxes you
created.
- Testbox queued/capacity pressure: do not convert a broad changed gate or full
suite into local
OPENCLAW_LOCAL_CHECK_MODE=throttled pnpm .... Leave the
remote lane queued, switch to a narrower targeted local check, or stop and
report the capacity blocker.
If Crabbox cannot dispatch, sync, attach, or stop but Blacksmith itself works,
first try the same command through the repo wrapper with --debug and
--timing-json:
pnpm crabbox:run -- --provider blacksmith-testbox --debug --timing-json -- \
CI=1 NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_TEST_PROJECTS_PARALLEL=6 OPENCLAW_VITEST_MAX_WORKERS=1 OPENCLAW_VITEST_NO_OUTPUT_TIMEOUT_MS=900000 pnpm test:changed
Full suite:
pnpm crabbox:run -- --provider blacksmith-testbox --debug --timing-json -- \
CI=1 NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_TEST_PROJECTS_PARALLEL=6 OPENCLAW_VITEST_MAX_WORKERS=1 OPENCLAW_VITEST_NO_OUTPUT_TIMEOUT_MS=900000 pnpm test
Auth fallback, only when blacksmith says auth is missing:
blacksmith auth login --non-interactive --organization openclaw
Raw Blacksmith footguns:
- Run from repo root. The CLI syncs the current directory.
- Save the returned
tbx_... id in the session.
- Reuse that id for focused reruns; stop it before handoff.
- Raw commit SHAs are not reliable
warmup --ref refs; use a branch or tag.
- Treat
blacksmith testbox list as cleanup diagnostics, not a shared reusable
queue.
Escalate to owned AWS/Hetzner only when Blacksmith is down, quota-limited,
missing the needed environment, or owned capacity is the explicit goal. Use the
Owned Cloud Fallback section below.
Blacksmith Backend Notes
Crabbox Blacksmith backend delegates setup to:
- org:
openclaw
- workflow:
.github/workflows/ci-check-testbox.yml
- job:
check
- ref:
main unless testing a branch/tag intentionally
The hydration workflow owns checkout, Node/pnpm setup, dependency install,
secrets, ready marker, and keepalive. Crabbox owns dispatch, sync, SSH command
execution, timing, logs/results, and cleanup.
Minimal Blacksmith-backed Crabbox run, from repo root:
pnpm crabbox:run -- --provider blacksmith-testbox --timing-json -- \
CI=1 NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_TEST_PROJECTS_PARALLEL=6 OPENCLAW_VITEST_MAX_WORKERS=1 pnpm test:changed
Use direct Blacksmith only when Crabbox is the broken layer and you are
isolating a Crabbox bug. Prefer direct blacksmith testbox list for cleanup
diagnostics, not as a reusable work queue.
Important Blacksmith footguns:
- Always run from repo root. The CLI syncs the current directory.
- Raw commit SHAs are not reliable
warmup --ref refs; use a branch or tag.
- If auth is missing and browser auth is acceptable:
blacksmith auth login --non-interactive --organization openclaw
Owned Cloud Fallback
Use AWS/Hetzner only when Blacksmith is down, quota-limited, missing the needed
environment, or owned capacity is explicitly the goal.
pnpm crabbox:warmup -- --provider aws --class beast --market on-demand --idle-timeout 90m
pnpm crabbox:hydrate -- --id <cbx_id-or-slug>
pnpm crabbox:run -- --id <cbx_id-or-slug> --timing-json --shell -- "env NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_TEST_PROJECTS_PARALLEL=6 OPENCLAW_VITEST_MAX_WORKERS=1 OPENCLAW_VITEST_NO_OUTPUT_TIMEOUT_MS=900000 pnpm test:changed"
pnpm crabbox:stop -- <cbx_id-or-slug>
Install/auth for owned Crabbox if needed:
brew install openclaw/tap/crabbox
crabbox login --url https://crabbox.openclaw.ai --provider aws
New users should self-resolve broker auth before anyone asks for AWS keys:
crabbox config show
crabbox doctor
crabbox whoami
- If broker auth is missing, run
crabbox login --url https://crabbox.openclaw.ai --provider aws.
- If the CLI asks for
AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, or AWS
profile setup during normal OpenClaw validation, assume the agent selected
the wrong path. Use brokered crabbox login, --provider blacksmith-testbox,
or an existing brokered lease before asking the user for cloud credentials.
- Ask for AWS keys only for explicit direct-provider/account administration,
not for normal brokered OpenClaw proof.
- Trusted automation may still use
printf '%s' "$CRABBOX_COORDINATOR_TOKEN" | crabbox login --url https://crabbox.openclaw.ai --provider aws --token-stdin.
macOS config lives at:
~/Library/Application Support/crabbox/config.yaml
It should include broker.url, broker.token, and usually provider: aws
for owned-cloud lanes. Do not let that config override the OpenClaw default
when Blacksmith proof is requested; pass --provider blacksmith-testbox.
Interactive Desktop / WebVNC
For human desktop demos, prefer webvnc over native vnc and keep the remote
desktop visible/windowed. Do not fullscreen the remote browser or hide the XFCE
panel/window chrome unless the explicit goal is video/capture output. After
launch, verify a screenshot shows the desktop panel plus browser title bar. If
Chrome is fullscreen, toggle it back with:
crabbox run --id <lease> --shell -- 'DISPLAY=:99 xdotool search --onlyvisible --class google-chrome windowactivate key F11'
Diagnostics
crabbox status --id <id-or-slug> --wait
crabbox inspect --id <id-or-slug> --json
crabbox sync-plan
crabbox history --limit 20
crabbox history --lease <id-or-slug>
crabbox attach <run_id>
crabbox events <run_id> --json
crabbox logs <run_id>
crabbox results <run_id>
crabbox cache stats --id <id-or-slug>
crabbox ssh --id <id-or-slug>
blacksmith testbox list
Use --debug on run when measuring sync timing.
Use --timing-json on warmup, hydrate, and run when comparing backends.
Use --market spot|on-demand only on AWS warmup/one-shot runs.
Failure Triage
- Crabbox cannot find provider: verify
../crabbox/bin/crabbox --help lists
blacksmith-testbox; update Crabbox before falling back.
- Hydration stuck or failed: open the printed GitHub Actions run URL and inspect
the hydration step.
- Sync failed: rerun with
--debug; check changed-file count and whether the
checkout is dirty.
- Command failed: rerun only the failing shard/file first. Do not rerun a full
suite until the focused failure is understood.
- Cleanup uncertain:
blacksmith testbox list; stop owned tbx_... leases you
created.
- Crabbox broken but Blacksmith works: use the direct Blacksmith fallback above,
then file/fix the Crabbox issue.
Boundary
Do not add OpenClaw-specific setup to Crabbox itself. Put repo setup in the
hydration workflow and keep Crabbox generic around lease, sync, command
execution, logs/results, timing, and cleanup.
