A summary, not legal advice.

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
