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.

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.
- Confirm the page links to a first-party product or repository source.
- Check the displayed rc version and last-verified timestamp.
- 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.
- Record the exact dsh, Node or Python version.
- State the operating system and installation method.
- 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.
