DeepSeek Open-Sources dsh-superagent, a Router-Worker Coding Agent

The DeepSeek Harness team just released dsh-superagent, an MIT-licensed research prototype.

DeepSeek dsh-superagent is a proactive coding agent for one GitHub repository.

It is packaged as a bundle for DeepSeek Harness.

It listens to GitHub and, optionally, Feishu.

It turns allowed requests into parallel work items, each in its own agent session.

The release shipped alongside a design post, Exploring Super-agent Design: Towards a More Autonomous Agent System.

TL;DaR What is it?: A TypeScript bundle, v0.1.0, released as 1 commit under MIT.

It uses whatever model the Harness profile is set to.

Runs on: Your own machine, as a dedicated DeepSeek Harness profile.

Needs Node.js 22.19+ or 24+, git 2.32+, Python 3.8+, tmux and GitHub CLI 2.48+.

Performance: In DeepSeek’s simulation, it finished tasks far faster under a noisy message stream than a single-session agent.

Best: p95 task completion of 15.7 minutes vs 29.5 minutes for the single-session baseline (about 1.9x faster).

Worst: Tested only on synthetic messages and simulated tools.

Real coding quality was not measured.

What is DeepSeek dsh-superagent?

It is a GitHub agent that waits to be asked.

When an allowed person addresses it, it opens a work item, called a Ticket.

Each Ticket runs in its own session and directory.
