dsh-v-explorer

DeepSeek Harness Web is conversation-first, but files in the working directory have no intuitive browsing surface. dsh-v-explorer borrows the VS Code sidebar model: a single toggle in the session header opens a lazy-loaded file tree, and a right-click menu covers open-in-explorer, copy path, insert as an @ reference into the composer, and launch HTML in the default browser—all without leaving the session window.

The bookmark panel lets you pin frequently used files or folders as virtual root trees, persisted per project and synced across tabs in real time via SSE; stale entries are flagged but never silently removed. Clicking a supported file opens a draggable floating preview: Markdown rendered with a Deep Ocean theme, JSON auto-formatted, and source code shown as escaped text, each format carrying its own style hook. The standout feature is the reference excerpt: select a range in the preview, send it with a line-number syntax, and the host snapshots the text at the exact moment the message enters the model step, so later edits cannot alter what the model already saw.

Built as a pure additive plugin that replaces no official component, it is ideal for developers who frequently browse, preview, or cite files inside their Harness working directory. Install, refresh, and the sidebar is ready.
