DeepSeek Harness makes the agent loop configurable

DeepSeek Harness is an open-source agent harness in developer preview. Its architecture treats model adapters, the tool registry, the session log, and the agent loop as plugins composed through profiles and bundles. Why it matters: The runtime composition can be inspected and changed without treating the agent loop as a fixed core. That makes the tool and policy choices easier to review, but the project warns that preview releases can include compatibility-breaking changes.

Try this: Run `dsh --profile web --dump-config` in a disposable workspace. Inspect the configured tools and policies before connecting credentials or real systems.
