--- name: openclaw/crabbox source: https://app.decimal.ai/s/openclaw-crabbox@1/SKILL.md source_sha256: 3272214ae10d --- # Crabbox Use Crabbox when a project needs remote proof, larger cloud capacity, a fresh PR checkout, a reusable warmed box, GitHub Actions-style setup, durable run logs/results, UI proof artifacts, or sync from a dirty local checkout. ## Detect Crabbox - Treat repo-root `crabbox.yaml` or `.crabbox.yaml` as an intentional signal to use this skill for validation work. `.crabbox.yml` is not a supported config filename. - If neither config exists, `command -v crabbox` still identifies an installed CLI. Run `crabbox doctor` before depending on it for remote work. - Inspect config before executing it. Detection does not imply permission to expose secrets, bypass command approval, or start paid infrastructure. ## Source Of Truth - Run Crabbox from the repository root; sync mirrors the current checkout. - Treat repo-local `crabbox.yaml` or `.crabbox.yaml` as executable project automation. Review it before remote runs, especially `provider`, `actions`, `jobs`, `profiles`, `env.allow`, artifacts, and cleanup policy. - Verify the installed binary before relying on examples: `command -v crabbox && crabbox --version && crabbox --help | sed -n '1,120p'`. - Use `crabbox providers` or `crabbox providers --json` for the current provider/capability matrix; provider docs can lag the compiled binary. - Use `crabbox doctor` for live readiness checks and `crabbox config show` to inspect merged config without printing secrets. - Prefer local targeted tests for tight edit loops. Move to Crabbox for broad suites, package-heavy checks, Docker/E2E/live-provider proof, cross-OS proof, UI proof, or commands that bog down the local machine. ## Auth And Config Brokered operation needs a coordinator URL and token. First login usually needs an explicit broker URL: ```sh crabbox login --url crabbox whoami crabbox doctor ``` After `broker.url` is configured, `crabbox login` can reuse it. Trusted operator automation can store a shared token without putting it on argv: ```sh printf '%s' "$CRABBOX_COORDINATOR_TOKEN" | crabbox login --url --provider aws --token-stdin ``` Config precedence is `flags > env > repo config > user config > defaults`. Default user config is `~/Library/Application Support/crabbox/config.yaml` on macOS, `~/.config/crabbox/config.yaml` on Linux, or `$XDG_CONFIG_HOME/crabbox/config.yaml` when set. `crabbox config path` prints the active user config path. Keep provider and broker tokens out of repo config and command arguments. Use environment variables, a credential store, coordinator-managed secrets, or a short-lived token command. ## Choose The Remote Surface - `crabbox run -- `: one command on a fresh or reused box. - `crabbox warmup`: create a reusable lease and run commands later with `--id`. - `crabbox prewarm`: warm a reusable lease and hydrate it from configured GitHub Actions. - `crabbox job run `: use a repo-local named flow that expands to warmup, optional hydration, run, and stop. - `crabbox run --pool `: borrow a hydrated broker ready-pool lease, run, then return/drain/release it according to `--pool-return`. - `crabbox run --fresh-pr ...`: ignore local sync and check out a GitHub PR on the remote; add `--apply-local-patch` to test local uncommitted changes on top of that PR. - `crabbox run --provider ssh`: use an existing macOS, Linux, or Windows host. - `crabbox warmup --desktop --browser`: provision a visible desktop/browser for UI testing, WebVNC, screenshots, and artifacts. If remote proof is blocked, name the missing capability precisely: auth, coordinator, capacity, provider support, target OS, hydration, secret access, artifact storage, desktop support, or a delegated-provider limitation. ## Common Remote Proof One-shot command: ```sh crabbox run --preflight --timing-json -- pnpm test ``` Warm and reuse a lease: ```sh crabbox warmup --class beast --idle-timeout 90m crabbox status --id --wait crabbox run --id -- pnpm test:changed crabbox run --id --full-resync -- pnpm test:changed crabbox stop ``` Use a repo-local job when configured: ```sh crabbox job list crabbox job run --dry-run crabbox job run crabbox job run --id ``` Use a ready-pool lease when the coordinator has hydrated pool capacity: ```sh crabbox pool ready crabbox run --pool -- pnpm test crabbox run --pool --pool-return drain -- pnpm test:flaky ``` Use GitHub Actions hydration when the repository already owns setup in CI: ```sh crabbox warmup --idle-timeout 90m crabbox actions hydrate --id crabbox run --id -- pnpm test ``` Use `--github-runner` only when the workflow needs full GitHub Actions semantics such as repository secrets, OIDC, service containers, job containers, or unsupported `uses:` steps: ```sh crabbox actions hydrate --github-runner --id ``` ## Sync And Fresh Checkouts Normal sync transfers tracked files plus non-ignored untracked files, excludes ignored dependency/build/cache output, honors `.crabboxignore` and `sync.exclude`, seeds the remote checkout from `origin` when possible, and skips rsync when the sync fingerprint matches. Use `crabbox sync-plan` before large runs. Unexpected counts usually mean local generated churn; update `.crabboxignore` or `sync.exclude` instead of forcing huge uploads. ```sh crabbox sync-plan crabbox run --debug --timing-json -- pnpm test crabbox run --full-resync -- pnpm test ``` Use fresh PR checkout when local dependency churn or dirty sync would confuse the result: ```sh crabbox run --fresh-pr example-org/my-app#123 --script ./scripts/e2e-smoke.sh crabbox run --fresh-pr 123 --apply-local-patch -- pnpm test ``` `--fresh-pr` accepts `owner/repo#number`, GitHub PR URLs, or a numeric PR from the current GitHub origin. Non-GitHub hosts are rejected. Fresh PR checkout is an SSH-run sync feature; delegated providers reject it. Native Windows SSH targets are supported. When a warm lease smells stale, prefer `--full-resync` (alias `--fresh-sync`) to reset the remote workdir, skip the sync fingerprint fast path, reseed Git when possible, and upload the checkout from scratch. ## Scripts, Shells, And Windows Targets Use plain argv after `--` for one executable. Use `--shell` for multi-statement shell snippets, pipes, or shell expansion: ```sh crabbox run --id -- go test ./... crabbox run --id --shell 'corepack enable && pnpm install --frozen-lockfile && pnpm test' ``` Prefer uploaded scripts for multi-line commands. Scripts are included in failure bundles and avoid brittle quoted shell strings: ```sh crabbox run --script ./scripts/e2e-smoke.sh --timing-json printf '%s\n' 'echo CRABBOX_PHASE:test' 'pnpm test' | crabbox run --script-stdin ``` Native Windows targets use PowerShell and tar-based manifest sync. Prefer plain argv for one executable such as `dotnet test`; use `--shell` for multi-statement PowerShell and `--script ` for longer scripts. ### Hyper-V Windows leases `hyperv` needs a Generation 2 VHDX, DHCP, and a known local administrator password in trusted config or `CRABBOX_HYPERV_GUEST_PASSWORD`. It installs pinned, verified OpenSSH and MinGit packages when missing, using PowerShell Direct. See `docs/providers/hyperv.md` for template and lifecycle details. For provider testing, prefer an elevated headless runner; early PowerShell Direct failures can show credential UI. Keep passwords out of arguments and logs, and verify the lease becomes ready, runs over SSH, and releases. ## Secrets And Environment Forwarding Crabbox does not forward the whole local environment. Forwarding is name-based: only allowlisted names that are actually set locally or in an allowed profile cross the boundary. Avoid allowlisting secret-shaped names unless the run is an explicit live-secret smoke. ```sh crabbox run --allow-env CI,NODE_OPTIONS -- pnpm test crabbox run \ --env-from-profile ~/.project-live.profile \ --allow-env API_TOKEN \ --preflight \ --script ./scripts/live-smoke.sh ``` `--env-from-profile` parses simple `export NAME=value` and `NAME=value` lines without executing the profile. Crabbox prints redacted presence/length metadata, not values. POSIX SSH leases can persist a helper for later commands on a lease you control: ```sh crabbox run \ --id \ --env-from-profile ~/.project-live.profile \ --allow-env API_TOKEN \ --env-helper live \ -- true crabbox run --id -- ./.crabbox/env/live ./scripts/live-smoke.sh ``` The generated helper and matching secret profile remain in the remote workdir until cleanup, lease reset, or `--full-resync`; do not persist helpers on shared or untrusted leases. ## Profiles, Presets, Proof, And Results Repo config can define profiles, presets, doctor requirements, artifact globs, required artifacts, and proof templates. Use them for stable validation lanes instead of encoding project knowledge in agent prompts. ```sh crabbox run \ --profile live-qa \ --preset qa-live \ --scenario login-regression \ --emit-proof /tmp/proof.md \ --stop-after success ``` Use `--preflight` for a target capability snapshot before the command, not as an installer. Use `--preflight-tools` to tune probes: ```sh crabbox run --preflight --preflight-tools node,bun,docker -- bun test crabbox run --preflight --preflight-tools default,uv -- node --test ``` Attach structured results and proof artifacts when the command emits them: ```sh crabbox run --junit reports/junit.xml -- ./scripts/test-with-junit.sh crabbox run --artifact-glob 'reports/**' --require-artifact reports/summary.json -- pnpm test:e2e crabbox run --download reports/summary.json=.crabbox/logs/summary.json -- pnpm test:e2e ``` `--require-artifact` fails the run if the remote command exits 0 but the proof file is missing. Keep required artifacts bounded and scrubbed; do not collect raw datasets, secrets, credentials, signed URLs, or unredacted customer rows. ## Run Handles And Observability Coordinator-backed runs print a durable `run_...` handle before leasing starts. Keep that run ID in status updates and PR notes. ```sh crabbox history --limit 20 crabbox history --lease --limit 20 crabbox attach crabbox attach --after crabbox events --after --limit 100 crabbox events --json crabbox logs crabbox results ``` Use `--timing-json` on `run`, `warmup`, and `actions hydrate` when a stable machine-readable timing record is needed. Commands can mark subphases by printing markers on stdout or stderr: ```sh echo CRABBOX_PHASE:install pnpm install --frozen-lockfile echo CRABBOX_PHASE:test pnpm test ``` Output events are capped previews. Use `logs` for retained output tails and `results` for parsed test summaries. ## Desktop, WebVNC, And UI Proof Create desktop/browser leases for visual QA, headed browser automation, or UI proof: ```sh crabbox warmup --desktop --browser crabbox warmup --provider aws --os ubuntu:26.04 --desktop --browser --desktop-env wayland crabbox warmup --provider aws --os ubuntu:26.04 --desktop --browser --desktop-env gnome ``` `ubuntu:26.04` is the default portable Linux OS selector where the provider catalog supports it. Use `--os ubuntu:24.04` only when a test must stay on the previous LTS. Explicit provider image flags still win over `--os`. For human demos, prefer WebVNC over native VNC because `crabbox webvnc --open` preloads the lease password in the browser fragment: ```sh crabbox webvnc --id --open --take-control crabbox webvnc status --id crabbox webvnc reset --id --open --take-control crabbox vnc --id --open ``` For input automation, use first-class helpers instead of hand-written `xdotool`: ```sh crabbox desktop doctor --id crabbox desktop launch --id --browser --url https://example.com --webvnc --open --take-control crabbox desktop click --id --x 640 --y 420 crabbox desktop paste --id --text "user@example.com" printf 'user@example.com' | crabbox desktop paste --id crabbox desktop type --id --text "user+qa@example.com" crabbox desktop key --id ctrl+l crabbox screenshot --id --output desktop.png ``` When desktop/WebVNC hangs, trust the inline rescue output first: `problem:` and `rescue:` lines usually name exact next commands such as `webvnc status/reset`, `desktop doctor`, or native `vnc --open`. Use artifacts for UI QA proof instead of committing screenshots or videos to a product repo branch: ```sh crabbox artifacts collect --id --all --output artifacts/ crabbox artifacts publish --dir artifacts/ --pr crabbox artifacts list crabbox artifacts pull --output /tmp/-proof ``` `artifacts publish` uses brokered storage when configured, or explicit S3/R2 / Cloudflare/local hosting flags. Use `--dry-run` before public PR comments when reviewing generated Markdown or storage commands. ## Provider Boundaries SSH-lease providers support the full sync/run surface when the target supports it: scripts, fresh PR checkouts, captures, downloads, Actions hydration, SSH, ports, WebVNC, code-server, desktop, browser, cache volumes, and cleanup. Delegated-run providers own command transport. Expect them to reject SSH-run features such as `--capture-stdout`, `--capture-stderr`, `--capture-on-fail`, `--script`, `--script-stdin`, `--fresh-pr`, local captures, `--download`, `--full-resync`, and `--env-helper` unless `crabbox providers --json` and the provider docs advertise the matching capability. `--keep-on-failure` is still useful for one-shot delegated providers that Crabbox would otherwise stop after a failed command. Module-runtime delegated providers, such as Cloudflare Dynamic Workers, run source modules rather than Linux shell commands. Use `--script ` or `--script-stdin` for module source; trailing `-- `, SSH, rsync, ports, Actions hydration, desktop, browser, and code-server do not apply unless the provider explicitly documents them. Use `--market spot|on-demand` on AWS `warmup` or one-shot `run` when account quota or capacity testing needs a temporary market override. An explicit `--type` means exact type; Crabbox reports quota/capacity/policy failures instead of silently falling back. ## Local And Static Targets Use `local-container` for fast local proof when the host has Docker or Podman. `warmup` creates a container but does not sync; for an interactive synced container, use `run --keep --sync-only`: ```sh crabbox run --provider local-container --keep --slug local-smoke --sync-only eval "$(crabbox ssh --provider local-container --id local-smoke)" ``` Pass `--local-container-runtime docker` or `--local-container-runtime podman` when the engine matters, and keep that flag on reused lease commands such as `run --id`, `ssh`, `status`, and `stop`. `crabbox ssh` prints an SSH command; use `eval "$(crabbox ssh ...)"` to connect. After login, `cd` into the workdir printed by `run --sync-only`. Use static SSH for existing machines: ```sh crabbox run --provider ssh --target macos --static-host mac.example.com -- xcodebuild test crabbox run --provider ssh --target windows --windows-mode normal --static-host win.example.com -- dotnet test ``` Static hosts are host-managed: Crabbox does not provision or delete them. ## Useful Commands ```sh crabbox providers crabbox providers --json crabbox doctor crabbox config path crabbox config show crabbox whoami crabbox sync-plan crabbox warmup --class beast crabbox prewarm crabbox status --id --wait crabbox inspect --id --json crabbox run --id --preflight --timing-json -- pnpm test crabbox job list crabbox job run --dry-run crabbox pool ready crabbox history --lease crabbox events --json crabbox attach crabbox logs crabbox results crabbox cache stats --id crabbox cache volumes crabbox ssh --id crabbox connect crabbox ports --id --publish 8080 crabbox cp --id ./coverage.xml SANDBOX:/tmp/coverage.xml crabbox webvnc --id --open crabbox code --id --open crabbox egress start --id --profile discord --daemon crabbox desktop doctor --id crabbox desktop proof --id --output artifacts/-proof -- ./scripts/visual-smoke.sh crabbox artifacts collect --id --all --output artifacts/ crabbox artifacts publish --dir artifacts/ --pr --dry-run crabbox usage --scope org crabbox pause crabbox resume crabbox stop ``` ## Failure Triage - Provider missing or old CLI: verify `crabbox --help` and `crabbox providers` list the provider, then rebuild or install a current binary. - Bad local config: compare `crabbox config show`, pass `--provider ...` explicitly, and run `crabbox doctor`. - Sync surprise: run `crabbox sync-plan`, add excludes, then retry with `--debug --timing-json` or `--full-resync`. - Raw box missing Node/pnpm/Docker: use `--preflight`; hydrate first if the repo has an Actions workflow, or include setup in the command/script. - Command failed: keep the `run_...` handle, inspect `results`, then rerun the focused failing shard/file before a full suite. - Desktop unhealthy: run `desktop doctor`, then follow `problem:` / `rescue:` output from `webvnc status` or `webvnc reset`. - Cleanup uncertain: use `crabbox list`, `crabbox inspect --json`, and only stop leases or provider resources you created. - Broker/auth confusion: use `crabbox doctor`, `crabbox whoami`, and `crabbox config show` before asking for cloud credentials. ## Cleanup Brokered leases have coordinator-owned idle expiry and local lease claims. Default idle timeout is 30 minutes unless config or flags set a different value. Still stop boxes you created when done: ```sh crabbox stop ``` When `crabbox list` prints `orphan=no-active-lease`, treat it as an operator review hint: verify the provider machine is not referenced by an active coordinator lease before deleting anything, especially if `keep=true` is set.
