DSH Image Download Plugin
Adds a download button when the pointer is over an image in a DeepSeek Harness conversation.
example
Install
Install the plugin through the DeepSeek Harness client or 1024 Store by
searching for the npm package name:
@zivye/dsh-img-save
Until the package is published to npm, the catalog lists this plugin
browse-only; the install command appears automatically once the npm
package is detected. The plugin itself ships under the name
dsh-img-save in the Web profile roster (see cordis.patch.yml).
Design
- Client-only behavior: the plugin uses the exact image URL that DSH is already rendering. It does not read local files, upload image bytes, run shell commands, or call a remote service.
- No polling or DOM observers: pointer, scroll, and resize events drive positioning. This avoids observer feedback loops and UI freezes.
- Preview-safe interaction: pointer/click events on the download button are stopped so clicking it does not trigger the image's built-in preview/lightbox action.
- Local URLs: uses the browser download mechanism for
file:, blob:, data:, and browser-accessible HTTP(S) image URLs. Browser security policy ultimately decides whether a particular local URL may be downloaded.

Development
The client entry is an ESM source file. The published package ships an esbuild
bundle at lib/client.js, which the 1024 Store loads through
exports["./client"]. Build the bundle locally:
npm install
npm run build
npm run check runs a syntax-only check on the source files.
Intended DSH integration
The client bundle is a Cordis plugin which registers with the queried
shell.overlay slot. It requires the DSH client runtime to provide:
slots.inject() and slots.register();- the
shell.overlay slot;
- React (provided as an npm dependency) and the dynamic client builtins
(
document, window, requestAnimationFrame).
cordis.patch.yml mounts the plugin into the Web roster of any DSH profile
that installs this package.
