## TESIGN TAKE

One command brings up the web UI, but this is a developer preview: treat it as something to study, not adopt.

## WHY IT MATTERS

An agent harness gets heavier with every capability added, and features nobody asked for come along with them. DeepSeek Harness takes the position that everything is a plugin, so only what is needed gets attached. It is written in TypeScript, published under MIT, and documented on its own homepage. The repository description is a single line, so the supported scope has to be read from the docs.

## BUILD FROM THIS

- An in-house agent setup carrying only the capabilities you need
- A shared set of internal plugins for the team

## WHO IT'S FOR

- Agent developer — wants to compose a harness from plugins
- Platform engineer — builds a shared plugin set for a team

## START IN 5 MINUTES

```
# With Node.js installed:
$ npx @deepseek-ai/dsh web
# The web UI opens at http://127.0.0.1:3080
```

## CAVEATS

- A developer preview; the README states there will be breaking changes
- It asks you to read the repository's safety notice before running it

## How to read this

- This file was produced by the same build, from the same data, as the tesign.com item page. The text is editorial; the numbers are stored observations.
- null in the JSON means not observed — never zero. The Markdown writes [unconfirmed] for it.
- Star total = the value last checked on GitHub (stars_checked_at) + increases observed via GH Archive since. The 24h · 7d · 30d gains are GH Archive hourly events summed to the reference time (as_of). No score of ours.
- A summary, not legal advice.
