View on GitHub

Use Crabbox from macOS, Linux, or native Windows controllers to run OpenClaw Windows node builds, tests, and targeted proof on remote native Windows or WSL2 hosts, including Azure or brokered AWS leases and static SSH hosts. Use when remote Windows validation is needed or the user asks for Crabbox validation. Always report the actual provider and lease id.

Crabbox

Use Crabbox as the transport for Windows-specific validation of this repository. Sync the current checkout to a native Windows host, run the same PowerShell and dotnet entrypoints required locally, collect the result, and stop leases created for the task.

This is a focused port of the OpenClaw Crabbox workflow. Do not copy its Linux pnpm, Blacksmith Testbox, macOS, Docker, package, or OpenClaw gateway-runtime lanes into this repository. They do not prove the Windows node.

Select the target

NeedProvider and target
Normal build, unit tests, CLI, WinUI, installer, or native Windows behavior--provider azure --target windows --windows-mode normal
WSL-side gateway/setup behavior on a Windows host--provider azure --target windows --windows-mode wsl2
An operator-managed Windows machine--provider ssh --target windows --windows-mode normal --static-host <host>
Azure is unavailable and the operator accepts the older AWS Windows path--provider aws --target windows --windows-mode normal

Prefer Azure for Windows and WSL2 work when the installed Crabbox CLI advertises it and Azure auth is already configured. Do not use WSL2 as proof for native WinUI, MSIX, Windows App SDK, PowerShell, registry, or Windows process behavior. Do not use Linux Testbox for this repo's required closeout validation.

First checks

Run from the repository root. Crabbox sync mirrors the current checkout, including tracked and relevant untracked changes.

Prefer the sibling development binary when present because a PATH shim may be stale:

export CRABBOX="$(command -v crabbox || true)"
if [ -x ../crabbox/bin/crabbox ]; then
  export CRABBOX=../crabbox/bin/crabbox
fi
export CRABBOX_PROVIDER="${CRABBOX_PROVIDER:-azure}"
test -n "$CRABBOX"
"$CRABBOX" --version
"$CRABBOX" run --help 2>&1 | rg 'provider|target|windows-mode|static-host|script-stdin|timing-json'
"$CRABBOX" config path
"$CRABBOX" whoami
git status --short --branch
git rev-parse HEAD

Keep CRABBOX and CRABBOX_PROVIDER exported in the shell that runs the remaining commands. If an automation tool starts a fresh shell for each call, replace them below with the resolved binary path and selected provider.

Require the CLI to list the intended provider and the windows target before starting a lease. Use explicit provider and target flags; this repository has no .crabbox.yaml, so inherited user defaults are not a validation contract.

Native Windows controller

When the Crabbox CLI itself runs on Windows, use PowerShell and prefer a sibling development binary over a possibly stale PATH install:

$Crabbox = if (Test-Path ..\crabbox\bin\crabbox.exe) {
    (Resolve-Path ..\crabbox\bin\crabbox.exe).Path
} else {
    (Get-Command crabbox.exe -ErrorAction Stop).Source
}
$CrabboxProvider = "azure"

Get-Command ssh, tar, git -ErrorAction Stop
& $Crabbox --version
& $Crabbox config path
git status --short --branch
git rev-parse HEAD

Use & $Crabbox and $CrabboxProvider in place of "$CRABBOX" and "$CRABBOX_PROVIDER" in later examples. PowerShell 5.1 or newer is sufficient for the controller commands.

For direct Azure, authenticate interactively and persist the approved location before warming a lease:

Get-Command az -ErrorAction Stop
az login
& $Crabbox azure login --location <approved-location>
& $Crabbox doctor --provider azure --target windows

Do not copy az login output or Crabbox config contents into logs, PRs, or chat. crabbox azure login stores Azure identifiers in the user config reported by crabbox config path. Set location with azure login; warmup has no --location flag.

Native Windows targets use local tar plus archive transfer, so a Windows controller does not need WSL or rsync for native-mode validation. POSIX and WSL2 targets use rsync. When wsl.exe exists, Crabbox prefers its rsync, so verify it inside the default distribution; without WSL, verify a native rsync is on PATH:

if (Get-Command wsl.exe -ErrorAction SilentlyContinue) {
    wsl.exe --exec sh -lc 'command -v rsync >/dev/null'
    if ($LASTEXITCODE -ne 0) { throw "Install rsync in the default WSL distribution." }
} else {
    Get-Command rsync.exe -ErrorAction Stop
}

Translate later POSIX here-doc examples into a PowerShell here-string when calling --script-stdin from Windows:

$RemoteScript = @'
# Copy the exact POWERSHELL body from the relevant example here.
'@
$PreviousOutputEncoding = $OutputEncoding
try {
    $OutputEncoding = New-Object System.Text.UTF8Encoding -ArgumentList $false
    $RemoteScript | & $Crabbox run `
        --provider $CrabboxProvider `
        --target windows `
        --windows-mode normal `
        --id <lease-id> `
        --preflight `
        --timing-json `
        --script-stdin --
    $CrabboxExitCode = $LASTEXITCODE
} finally {
    $OutputEncoding = $PreviousOutputEncoding
}
if ($CrabboxExitCode -ne 0) { exit $CrabboxExitCode }

If public SSH is blocked and the operator confirms an approved VPN route to the Azure virtual network is already active, opt into private addressing for that session with $env:CRABBOX_AZURE_NETWORK = "private", then rerun crabbox doctor. Do not port or automate organization-specific VPN, certificate, vault, subscription, tenant, resource, address, or account setup in this skill.

Azure requires its subscription auth and usually the Azure CLI. If Azure is unavailable, use AWS only with an existing Crabbox broker session. If normal AWS validation asks for AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, an AWS profile, or an EC2 instance role, stop: the command fell through to raw cloud auth. Check crabbox config path, crabbox doctor, and crabbox whoami, then authenticate through the broker if authorized:

"$CRABBOX" login --url https://crabbox.openclaw.ai --provider aws
export CRABBOX_PROVIDER=aws

Do not ask the user for raw cloud keys for routine repository validation. Report an auth blocker when neither Azure nor brokered AWS nor an approved static host is available.

Treat contributor or fork code as untrusted until it has been reviewed. This repo does not carry OpenClaw's sanitized Crabbox bootstrap, so do not run unreviewed code on a credentialed or operator-managed Windows host. Use secretless fork CI, or review the exact head and diff before syncing it. --fresh-pr changes checkout mechanics; it does not make untrusted code safe.

Warm and reuse native Windows

Warm one lease early for tasks that will need several build/test iterations:

"$CRABBOX" warmup \
  --provider "$CRABBOX_PROVIDER" \
  --target windows \
  --windows-mode normal \
  --keep \
  --idle-timeout 90m \
  --ttl 240m \
  --timing-json

For UI work, add --desktop to this warmup from the start and use the returned id as both <lease-id> and <desktop-lease-id>. Managed leases cannot gain desktop capability after acquisition. Do not add --desktop to WSL2; managed WSL2 has no separate VNC desktop.

Save the returned raw lease id. Report the provider and id exactly as Crabbox returns them. Reuse the lease with --id <lease-id>, but let each run sync the current checkout. Use --no-sync only for an intentional rerun of unchanged source. If the remote tree looks stale, retry with --full-resync before replacing the lease.

Run required validation

Run the repository-required closeout sequence on native Windows. The explicit test-project builds prevent a fresh remote checkout from silently no-oping on the later --no-restore test commands.

"$CRABBOX" run \
  --provider "$CRABBOX_PROVIDER" \
  --target windows \
  --windows-mode normal \
  --id <lease-id> \
  --preflight \
  --timing-json \
  --script-stdin -- <<'POWERSHELL'
$ErrorActionPreference = 'Stop'
$env:OPENCLAW_REPO_ROOT = (Get-Location).Path

& .\build.ps1
if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }

dotnet build .\tests\OpenClaw.Shared.Tests\OpenClaw.Shared.Tests.csproj
if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }

dotnet build .\tests\OpenClaw.Tray.Tests\OpenClaw.Tray.Tests.csproj
if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }

dotnet test .\tests\OpenClaw.Shared.Tests\OpenClaw.Shared.Tests.csproj --no-restore
if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }

dotnet test .\tests\OpenClaw.Tray.Tests\OpenClaw.Tray.Tests.csproj --no-restore
if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }
POWERSHELL

If prerequisites are missing, diagnose first with:

.\scripts\setup-dev.ps1 -CheckOnly

Use .\scripts\setup-dev.ps1 to install or verify prerequisites, then rerun the complete validation block. If an app locks build outputs, stop that process and rerun all required commands. Never report a prerequisite failure or a skipped test as passing validation.

Add the targeted suite required by AGENTS.md for the touched subsystem. For example, changes to winnode, MCP output, or command docs also require:

dotnet build .\tests\OpenClaw.WinNode.Cli.Tests\OpenClaw.WinNode.Cli.Tests.csproj
if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }

dotnet test .\tests\OpenClaw.WinNode.Cli.Tests\OpenClaw.WinNode.Cli.Tests.csproj --no-restore
if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }

MXC, system.run, approval, or Windows command-execution changes also require:

.\scripts\validate-mxc-e2e.ps1

Do not treat -AllowSkip as merge validation for MXC-related work.

Use WSL2 narrowly

Use WSL2 only when the behavior under test crosses the WSL gateway boundary. Keep the full native Windows closeout run above even when a targeted WSL2 proof passes. Warm WSL2 separately because its VM provisioning and bootstrap differ from native mode:

"$CRABBOX" warmup \
  --provider "$CRABBOX_PROVIDER" \
  --target windows \
  --windows-mode wsl2 \
  --keep \
  --idle-timeout 90m \
  --ttl 240m \
  --timing-json

Save the returned id as <wsl2-lease-id>, then run the focused WSL proof:

"$CRABBOX" run \
  --provider "$CRABBOX_PROVIDER" \
  --target windows \
  --windows-mode wsl2 \
  --id <wsl2-lease-id> \
  --preflight \
  --timing-json \
  --script-stdin -- <<'BASH'
set -euo pipefail
# Run the smallest repository WSL/setup command that proves the changed path.
BASH

Read docs/WSL_EXE_ARGV_PITFALL.md before adding or changing any multi-line WSL script passed through RunInWslAsync.

Use a static Windows host

For an operator-managed machine, use the SSH provider and make the target contract explicit:

"$CRABBOX" run \
  --provider ssh \
  --target windows \
  --windows-mode normal \
  --static-host win-dev.local \
  --static-user <user> \
  --preflight \
  --timing-json \
  -- dotnet --info

Native Windows sync requires OpenSSH, PowerShell, Git, and tar. Set --static-port or --static-work-root when the host differs from Crabbox defaults. Never overwrite real tray settings during proof; use an isolated data directory as required by AGENTS.md and the proof-validation skill.

Collect real behavior proof

Remote build and test output proves automation, not visible WinUI behavior. For tray, Settings, onboarding, chat/canvas, or other UI claims, launch the isolated app in an interactive Windows session and capture current-head evidence:

"$CRABBOX" desktop launch \
  --provider "$CRABBOX_PROVIDER" \
  --target windows \
  --windows-mode normal \
  --id <desktop-lease-id> \
  --webvnc \
  --open \
  --take-control -- \
  powershell.exe -NoProfile -ExecutionPolicy Bypass -File '.\run-app-local.ps1' \
    -NoBuild -Isolated -AllowNonMain

If the leased host has no interactive desktop, state that UI proof is blocked and keep the automated Crabbox result. For node/MCP changes, collect the live winnode --list-tools and winnode --command ... proof required by .agents/skills/openclaw-proof-validation/SKILL.md.

Observe and troubleshoot

Use Crabbox's built-in diagnostics before adding ad hoc logging:

  • --preflight prints the Windows workspace, SSH, PowerShell, execution policy, long-path, temp, and tool probes.
  • --timing-json emits the machine-readable provider, lease, sync, command, and exit summary.
  • --debug adds sync and transport diagnostics.
  • --capture-stdout <path> and --capture-stderr <path> retain noisy output locally; treat captured output as potentially secret-bearing.
  • --capture-on-fail downloads standard failure artifacts when the direct provider supports it.
  • --keep-on-failure preserves a failed one-shot lease for bounded debugging.
  • --script <file> or --script-stdin avoids fragile multi-layer quoting; native Windows scripts run through Windows PowerShell.

Useful read-only commands:

"$CRABBOX" status --id <lease-id> --wait
"$CRABBOX" inspect --id <lease-id> --json
"$CRABBOX" history --limit 20
"$CRABBOX" history --lease <lease-id>
"$CRABBOX" logs <run-id>
"$CRABBOX" results <run-id>

On failure, distinguish provider acquisition, SSH, sync, prerequisites, and the test command. Retry transport or sync once with --debug --timing-json; rerun only the focused failing command until understood, then rerun the full required validation. Do not silently move Windows proof to Linux or WSL2.

On a Windows controller, diagnose sync by target mode: native Windows should use archive transfer and needs local tar; POSIX or WSL2 uses rsync and selects WSL rsync whenever wsl.exe is installed. Do not install WSL solely for a native Windows target.

Cleanup and report

Stop every cloud lease created for the task unless the user explicitly asks for a handoff window:

"$CRABBOX" stop --provider "$CRABBOX_PROVIDER" <lease-id>
"$CRABBOX" stop --provider "$CRABBOX_PROVIDER" <wsl2-lease-id>
"$CRABBOX" stop --provider "$CRABBOX_PROVIDER" <desktop-lease-id>
"$CRABBOX" list --provider "$CRABBOX_PROVIDER"

Run only the unique stop commands for leases actually created. If providers differed, use each lease's actual provider instead of the current variable. Do not stop shared or pre-existing leases. In the handoff or PR body, record:

  • source head SHA and whether the checkout was dirty
  • actual provider, target, Windows mode, and raw lease id
  • exact commands and pass/fail counts
  • focused real-behavior proof, or an explicit blocker
  • cleanup result

Never call a WSL2 run native Windows proof, and never call a skipped/no-op test successful validation.
