The Harness is useful, but it can also read and edit files, run commands, install plugins, and store model credentials. I wanted a repeatable setup where the agent starts with a much smaller view of the host.</p> <p>This builds on my earlier note about <a href="https://singularity.sg/2026/08/deepseek-released-the-agent-harness-too/">why I want to try DeepSeek Harness</a>. The difference here is packaging and containment rather than another agent plugin.</p>
