About this plugin
Browsing workspace files, previewing documents, or editing content in DeepSeek Harness Web used to mean leaving the browser and opening a local editor, breaking the flow of an ongoing conversation or task. dsh-preview-ui brings file browsing, format preview, and inline editing directly into the browser panel, with zero external dependencies.
The plugin renders a lazy-loaded, filterable file tree and previews a wide range of formats: syntax-highlighted code, full Markdown, images, PDFs, Office files (DOCX/XLSX/PPTX via OOXML parsing), sandboxed HTML, and binary hex dumps. A textarea with a highlight overlay enables online editing; pressing Ctrl+S saves the file and automatically writes a version snapshot, keeping up to 50 reversible snapshots per file. It also ships with full-text search, drag-and-drop preview of local files or entire project folders, and two Agent tools (list_files, preview_file) so a conversing Agent can proactively open the preview panel.
Built for developers who live in DSH Web and frequently need to inspect workspace source and docs, quickly verify PDF or Office content, make quick text edits with full revision history, or wire file preview into Agent-driven automation workflows.
Use Cases
- Quickly preview PDFs, Office docs, or code files inside a DSH conversation
- Edit text files inline and roll back to a previous snapshot via version history
- Drag a local project folder into the panel to recursively browse and preview its contents
Best For
- Developers who frequently inspect workspace source and docs in DSH Web
- Users who need to preview multi-format files and make quick edits entirely in the browser
- Automation builders who want an Agent to proactively open the file preview panel
