Plugin Overview & Capabilities

AI-assisted organization based on the public repository snapshot. The content must be grounded in source evidence and does not replace compatibility or security verification.

source-grounded
dsh-viewer (@crosery/dsh-viewer) is a DeepSeek Harness plugin providing a display_file tool that embeds rich media directly into the web UI. Supporting 36 file extensions across 6 render types—including images, seekable videos, audio players, interactive PDFs, Office document conversions via LibreOffice, and sandboxed HTML—it streams assets over a signed HMAC HTTP route with range requests and feeds compatible image files back into the model's visual context.

Key Capabilities

  • Displays 36 file formats inline including images (PNG, JPG, SVG, WebP), video (MP4, WebM), audio (MP3, WAV, FLAC), PDF, Office files, and HTML
  • Streams local media securely using per-harness HMAC-signed HTTP routes supporting byte-range seeking
  • Integrates with LibreOffice to automatically convert DOCX, XLSX, and PPTX files into viewable PDFs
  • Dual-feeds supported raster images directly into vision-capable model context while displaying visual cards
  • Intercepts binary read failures gracefully to redirect execution to display_file
  • Sandboxes HTML rendering with strict Content-Security-Policy headers to protect the host origin

Useful For

  • Reviewing visual artifacts, design assets, and charts generated by agents in real time
  • Playing back agent-generated or workspace audio and video files without external desktop apps
  • Previewing Office documents (Word, Excel, PowerPoint) and generated PDF reports directly inside DSH chat
  • Inspecting sandboxed local web pages and HTML reports within the DeepSeek Harness UI

Who It Fits

  • DeepSeek Harness web UI users working with multimodal workflows
  • Developers inspecting generated media, charts, and document artifacts
  • Data analysts and researchers viewing Office spreadsheets, slide decks, and audio/video files

Documented Limitations

  • Requires LibreOffice installed on host PATH to convert and render Office documents
  • Supports local file paths only; remote external URLs cannot be fetched directly
  • Does not transcode unsupported codecs (e.g., ProRes inside .mov containers)
  • Remote workspaces without local filesystem paths cannot stream non-image media files
