DeepSeek Harness Plugin: dsh-trail-plugin

dsh-trail-plugin adds a "History Index" sidebar to DSH to address the difficulties of locating specific points and switching branches within linear conversation logs. By utilizing a persistent index, the plugin supports inline navigation, node continuation, fork switching, and left-panel collapse adjustment. To enable it, users need to install Node.js ≥ 20 and restart DSH. This tool is designed for developers who need to quickly locate context in complex, lengthy conversations or conduct multi-branch experiments.
