DSH Image Download Plugin

Adds a download button when the pointer is over an image in a DeepSeek Harness conversation.

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.
