DeepSeek's open-source agent runtime (dsh): everything is a plugin, one npx command for the Web UI. Developer preview, MIT.
Why it's listed
If you want to take a coding agent apart and see how it turns, DeepSeek Harness is the most direct open chassis right now: model, tools, session and loop are all swappable. It is still a developer preview — good for learning the architecture and writing plugins, not for pinning production flows to the current API.
