Quick start

DeepSeek Harness quick start

Use this page as a short checklist before you open the official repository. The goal is to inspect the harness as runtime infrastructure, not only to confirm that a command launches.

Run from npm

The official preview command is:

npx @deepseek-ai/dsh web

Run from source

Clone the official repository, install dependencies and launch the Web UI from the checkout.

git clone https://github.com/deepseek-ai/deepseek-harness

What to inspect first

  1. Which plugins are mounted for the selected runtime mode.
  2. Whether a run records prompts, tool calls, observations and context injections clearly.
  3. How Standard, Code, Minimal and Creator modes change the capability surface.
  4. Which safety or permission boundaries appear before a tool can affect local state.
