dsh → Scan VM

One-line setup for DeepSeek Harness pointed at our shared inference box. Windows, PowerShell.

What it does

• Checks Node (needs ^22.19 or >=24 — note 23 does not qualify) and PowerShell 7, and offers to install either with winget if missing.
• Confirms the Scan VM is reachable and actually serving the model.
• Installs dsh globally at a pinned version.
• Writes the provider route to %USERPROFILE%\.dsh\settings.yaml.

Safe to re-run. It will not overwrite an existing llm-pi-ai section — it writes a sidecar file for you to merge instead.

Then

cd C:\path\to\your\project
dsh web

Open http://127.0.0.1:3080, click Choose workspace, pick your project directory, then select the model in the picker.

Updating

Run the same one-liner again. It is version-aware: if you are already on the pinned version it does nothing, otherwise it updates you to it.

irm https://ai.mindprobe.xyz/go | iex

Do not run npm update -g @deepseek-ai/dsh. It drops the --allow-scripts flag, so koffi never rebuilds and the Windows sandbox fails closed with SANDBOX_UNAVAILABLE on every command. The version here is pinned deliberately — dsh is a developer preview and upstream promises compatibility-breaking changes.

Config files are left alone on a re-run. To pick up a changed model route, use -Force (it backs up your settings.yaml first).

Options

To pass arguments through irm, wrap it in a scriptblock:

& ([scriptblock]::Create((irm https://ai.mindprobe.xyz/go))) -Reasoning xhigh

• -Reasoning — off, low, medium (default), xhigh. Nothing else is valid on this server.
• -Yes — answer yes to every prompt. Required for unattended runs, since a non-interactive host cannot be asked.
• -NoInstall — never install anything; report what is missing and stop.
• -Reinstall — reinstall dsh even when already at the pinned version (for repairing a broken install).
• -ConfigOnly — rewrite settings.yaml, skip the npm install.
• -Force — replace an existing llm-pi-ai section (backs it up first).
• -Endpoint, -ModelId, -DshVersion — override the defaults.

Before you paste

irm … | iex runs whatever this server returns, with your user's authority. That is fine because this is our domain and our script — but the habit is worth keeping deliberate. Read the script first if you have not seen it.

Troubleshooting

• Cannot reach the Scan VM — check you are on the office network, then Test-NetConnection 10.2.2.7 -Port 48765.
• Node too old — winget install OpenJS.NodeJS.LTS, then open a new terminal.
• dsh not found after install — open a new terminal so PATH refreshes, or use npx @deepseek-ai/dsh web.
• UNSUPPORTED_REASONING_EFFORT — something added high, max or minimal to reasoningEfforts. This server rejects all three.
