dsh-image-preview

When you call the built-in read_image tool in DeepSeek Harness, image results are usually rendered as an abstract tool row with little visual context. dsh-image-preview plugs into DSH's public tool.call.toolview slot to inject an inline renderer, so you see the actual image right inside the tool tree. A single renderer covers both direct read_image calls and tools.read_image(...) subcalls nested inside run_code Code Mode, with no extra wiring required.

On the security side, every byte is fetched exclusively through the authenticated session attachment API via ctx.sessions.binding. The model-supplied file path is treated as display metadata only and is never re-read by the browser plugin. Rendering is limited to authenticated PNG, JPEG, WebP, and GIF attachments. Clipboard copies reuse the same attachment Blob, and formats that lack direct clipboard support are converted to PNG in-browser with no network fallback. Malformed or expired attachments degrade to a bounded inline message rather than failing silently.

If your daily workflow involves DeepSeek Harness vision capabilities—OCR, image description, side-by-side comparison, or multi-step image pipelines orchestrated in Code Mode—this plugin makes every intermediate image result visible at a glance. From the DSH Settings plugin card you can toggle the inline-preview renderer on or off and choose whether previews expand automatically or stay collapsed until you click Show preview.
