DeepSeek open-sources dsh-superagent, an autonomous GitHub agent

DeepSeek open-sourced dsh-superagent-prototype on 31 October, a research prototype from its Harness team for running a proactive coding agent against a single GitHub repository. The code is on GitHub under the MIT licence.

The agent watches GitHub, and optionally Feishu, for requests from people on an allowed list. When someone permitted asks for something in an issue or pull request, or a rule the team wrote permits it, the agent takes the work in its own session and replies, usually with a pull request. Running it yourself needs a configured model provider, a dedicated GitHub account and a machine that stays on, since there’s no managed hosting. DeepSeek is explicit that this is reference code: not an official product, not the version it runs internally, and not production-ready.

Why it matters: proactive coding agents are usually sold as a hosted product with the wiring hidden. This gives you a working router and worker implementation, the authorisation rules and the GitHub webhook handling to read, adapt or run yourself, rather than reverse-engineering someone else’s black box.

The caveat: DeepSeek calls this research code, not production-ready, and says some of it was written by AI agents rather than reviewed line by line by a person.
