DeepSeek Harness Python SDK: Install & Quickstart
The official Python distribution is deepseek-harness-sdk, imported as deepseek_harness. Its guide requires Python 3.10+, bundles the runtime, and warns that the minimal example uses danger-full-access and belongs in a disposable checkout or container. 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.

Evidence basis: Official SDK docs + PyPI identity. 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.
- Create an isolated Python 3.10+ environment.
- Install deepseek-harness-sdk, not the similarly named third-party package.
- Use a disposable workspace and a fresh session id for the first run.
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.
