DeepSeek Open-Sources a Prototype That Finds and Fixes Bugs
DeepSeek’s Harness team released an open-source coding-agent prototype under the MIT license.
The system uses a central Router to assign work to separate, isolated Workers.
Those Workers react to GitHub and chat events and can try to fix reported bugs.
They can also respond to bug reports in group chats even when they are not directly tagged.
Once a fix is ready, the system can open a pull request for people to review.
The prototype aims to automate bug fixing, but no further plans for it are stated.
