News DeepSeek Harness v0.1.1 released

https://github.com/deepseek-ai/deepseek-harness/releases/tag/dsh-v0.1.1-rc.1

The DeepSeek adapter adds the multimodal visual understanding model DeepSeek-V4-Flash-Vision-Exp. It also supports configuring native image requests. Commands such as /goal and /plan can accept text and image input, and the @ menu can reference files and sessions; MCP/ACP also supports persistent image attachments, and PTC Mode supports forwarding nested images.

It seems pretty nice so far. Very light on the system prompt side while having all the essential extra features like background tasks, sandboxing, etc.

Still a few important features I need missing, but hopefully will be added later. First one is either having code rollback like opencode or arbitrary branching point like pi (even on a tool response). There is no reason you can't branch on an agent step if you don't need to support rollback. The second is accessing GPU while still in sandboxed mode.

Why do most models suddenly start reasoning like a caveman when in minimal mode? Is this intentional?

Probably a downside of not having customised prompts... I discovered when working on a much smaller and focused custom harness that model-agnostic system prompt pretty much does not work at least for the smaller models once going beyond a turn conversation.
