DeepSeek Harness Quickstart: From Install to First Task

The reliable first run is deliberately small: confirm a supported Node environment, launch the official npm package, open the local Web UI, configure a model credential, select a workspace and submit a harmless inspection task. This page separates verified behavior from community reports and marks the release-candidate context so you can act without mistaking an observation for a permanent guarantee.

What is verified now

The reliable first run is deliberately small: confirm a supported Node environment, launch the official npm package, open the local Web UI, configure a model credential, select a workspace and submit a harmless inspection task.

Evidence basis: Official README and Web UI guide. The status was checked on 14 August 2026; re-check the linked source after any dsh release.

Safe workflow

Use the smallest reversible workflow first. Do not add community plugins or paste credentials while validating the base behavior.

  1. Confirm the page links to a first-party product or repository source.
  2. Check the displayed rc version and last-verified timestamp.
  3. Follow the dedicated setup or troubleshooting guide for the next action.

Verify before moving on

A successful result should be observable: a version string, reachable local URL, valid provider response, loaded configuration, or disappearance of the exact error. If the result differs, stop and capture sanitized evidence rather than stacking unrelated fixes.

  1. Record the exact dsh, Node or Python version.
  2. State the operating system and installation method.
  3. Link the first-party source and include only sanitized logs.

First-party sources

Open the original source before acting on a changed version or unresolved community report.
