About this skill

Native Gateway from source

scripts\Build-NativeGatewayFromSource.ps1 builds OpenClaw from source, packages it with openclaw/openclaw-windows-packaging, and registers a Developer Mode loose package named OpenClawFoundation.OpenClawGateway-<patch> with aliases openclaw-<patch>.exe and clawctl-<patch>.exe. A "patch" is a side-by-side identity slot (upstream Deploy-LocalPackage.ps1 -Patch), not a version: each patch has its own app data, isolated agent account, and Gateway port, and never touches the Store package.

Companion uses the patch only when started with OPENCLAW_NATIVE_GATEWAY_DEV_PATCH=<patch>. Without it, Companion resolves the Store package and installs it with WinGet only when missing. See docs/ONBOARDING_WIZARD.md and docs/ARCHITECTURE.md (native Gateway section).

Prerequisites

Check before building; the script fails fast on most of these:

  • Windows Developer Mode on, isolated-session-capable Windows (native setup's device check).
  • PowerShell 7.4 or later (pwsh). Windows PowerShell 5.1 cannot run the script.
  • git, .NET SDK 10.0.400 or later, Visual Studio Build Tools with C++ and the Windows SDK (the packaging repo builds NativeAOT executables).
  • Node.js 24.16 or later whose process.platform/process.arch is win32/<OS arch>.
  • pnpm with the same major as the source's packageManager (main uses pnpm 12): npm install -g pnpm@<version>. The script prints the exact version on mismatch.

Build and register the latest Gateway

pwsh -File .\scripts\Build-NativeGatewayFromSource.ps1 -OpenClawRef main -Patch source
  • First run clones both repos under %SystemDrive%\OpenClawDev\native-gateway-source and takes roughly 25 to 30 minutes (pnpm build dominates). Run it in the background and do not poll.
  • Success ends with Registered OpenClawFoundation.OpenClawGateway-source_<hash> and OpenClaw <version> (<full sha>). Compare the sha with git ls-remote https://github.com/openclaw/openclaw refs/heads/main.
  • main of both repos moves often. Each rerun fetches them again; a new commit in either repo builds and re-registers a new payload. To get a reproducible rerun, pin both: -OpenClawRef <full sha> -PackagingRef <full sha>. A pinned rerun prints Reusing payload and Already up to date without rebuilding. ACL validation still walks the checkouts and selected payload; large dependency trees take longer.
  • Other sources: -OpenClawSourceDirectory <checkout> builds a local checkout as-is (uncommitted changes allowed, always a fresh payload). -OpenClawPackageDirectory <dir> takes an existing openclaw.tgz + source.json and only builds the payload (about 2 to 3 minutes); previous builds leave these under <WorkRoot>\packages\<id>.
  • -Force builds a new payload and re-registers even when nothing changed.
  • Relative -WorkRoot paths are anchored to the invoking PowerShell location before any directory changes.
  • Only one source build or unregister can run on a machine at a time, even across different patches and work roots. A concurrent invocation fails before changing files. Payload installation also uses a fresh per-run staging directory, removed on exit.
  • Prebuilt packages must include valid commit/hash/version metadata. The archive hash is checked before payload-cache reuse, not just on a fresh build.

Verify the registration:

Get-AppxPackage -Name OpenClawFoundation.OpenClawGateway-source |
    Format-List PackageFamilyName, Version, Publisher, IsDevelopmentMode, InstallLocation
$alias = "$env:LOCALAPPDATA\Microsoft\WindowsApps\OpenClawFoundation.OpenClawGateway-source_rfcbke2p71se2"
& "$alias\clawctl-source.exe" --version        # Payload line shows the source sha
& "$alias\clawctl-source.exe" status --json    # integration.kind = isolated-session

Run Companion against it

Use isolated tray data so the user's real settings and gateways are untouched:

.\build.ps1
$env:OPENCLAW_NATIVE_GATEWAY_DEV_PATCH = 'source'
$env:OPENCLAW_FORCE_ONBOARDING = '1'
.\run-app-local.ps1 -NoBuild -DataDir "$env:TEMP\oc-devgw-source"

In setup choose Install a local native gateway, then Set up gateway. Expected: all four native steps complete and Connect your AI loads from the source-built Gateway. <data-dir>\gateways\native-setup-draft.json records PackageFamilyName = OpenClawFoundation.OpenClawGateway-source_rfcbke2p71se2, and clawctl-source gateway-service status reports [ok] listening on the recorded port. No winget.exe should start. Clear both variables afterwards.

The variable must be set in the shell that launches Companion; a running Companion does not pick it up. Profiles created this way resolve only while the variable names the same patch.

Remove it

pwsh -File .\scripts\Build-NativeGatewayFromSource.ps1 -Unregister -Patch source

This runs clawctl-source teardown --force (removes the isolated session, Gateway records and agent profile), then unregisters. The Store package stays. Payloads and checkouts under the work root are kept; delete them manually only after unregistering. Pass the same -WorkRoot/-PackagingDirectory/-Architecture used to register, or the ownership check refuses before teardown.

Pitfalls

  • Never put the work root or packaging checkout under the user profile. The Gateway runs as a separate isolated agent account that must read the payload through every parent folder; under C:\Users\<you> Node fails with EPERM ... lstat 'C:\Users\<you>\AppData' and setup reports "OpenClaw could not read the effective Gateway configuration". The script refuses such paths. Do not "fix" it with ACL grants.
  • Build trees must not be writable by other accounts. Newly created work directories have protected ACLs: the current user, Administrators and SYSTEM can write; other authenticated accounts, Users and application-package groups get read/execute only. Existing trees, supplied checkouts and prebuilt packages are checked, including linked targets and replaceable ancestors. Unsafe paths are rejected without changing their ACLs. Use a fresh root under a trusted parent (for example C:\OpenClawSourceSafe), not another child of an unsafe directory. For an existing registration, have an administrator verify its files and repair its permissions before retrying unregister. Do not execute potentially modified aliases merely to bypass the check.
  • Never move or delete the work root while registered. The layout links the payload with a junction. Moving keeps the old ACLs (the agent account loses access); icacls /reset /T over the openclaw checkout loops through pnpm symlinks for a long time. Unregister, then rebuild in the new location.
  • A cancelled source build leaves openclaw\.artifacts\dist-artifacts.lock. The next pnpm build refuses with "Could not acquire ... dist-artifacts.lock". After confirming no build process is still running, remove that directory and rerun.
  • Do not run native setup without the variable on a host whose Store Gateway is in use. It pairs a new device with that live Gateway. Prove Store resolution without side effects instead (unit tests, or call NativeGatewayPackageResolver from a throwaway program).
  • Payloads are architecture-specific. An x64 payload on ARM64 registers but clawctl setup fails there (upstream note); build on the target architecture.

Error messages and what they mean

Message Cause Action
The development Gateway package ...-<patch> is not registered ... (new setup) Variable set, patch not registered Run the build, or clear the variable to use the Store Gateway

Proof for PRs

For PRs that depend on a source-built Gateway, follow openclaw-proof-validation: report the registered family, clawctl-<patch> --version, the commit tested, and focused app-window screenshots. Never publish gateways.json, setup drafts beyond family and port, tokens, or identity files.
