DeepSeek team open-sources proactive coding agent research prototype

DeepSeek’s Harness team has open-sourced dsh-superagent, a research prototype that receives development requests through GitHub and optionally Feishu, works on them in separate sessions, and returns results such as pull requests to the original conversation. The prototype is configured around a single GitHub repository and runs as a bundle for DeepSeek Harness. It converts authorized requests into work items, gives each task its own working directory and agent session, and provides a web panel showing matters that need human attention. The project explores how coding agents can carry out longer-running work while requiring less human coordination. The published implementation grew out of the team’s daily development workflow and is available under the MIT license. [DeepSeek]
