Plugins

Model-facing display_file tool that renders 36 file extensions inline in the web UI: images with a click-to-zoom lightbox, seekable video, audio, PDF, Office and OpenDocument files converted to PDF on the host via LibreOffice, and local HTML in a sandboxed frame; bytes stream from a signed HTTP route with range support, and PNG/JPEG/WebP/GIF also enter model context on image-capable routes.

GPT Image 2 `image_gen` with Codex subscription OAuth by default or explicit API-key mode: developing card, up to three live API partials, durable attachment replay/lightbox/download, text-only model output, and bounded credential-safe requests.

Image previews for DSH sessions: read_image thumbnails plus user, assistant, Markdown and present images in a lightbox with zoom, rotate, pan, download, sidebar and native file actions.

Render local image paths from assistant replies inline in the message body (9 formats, click-to-zoom lightbox, adjustable size).

Upgrades DSH image viewing with pointer-centered zoom, pan, galleries, downloads, keyboard support, and inline region notes.

Full-screen lightbox for chat images: click any image to open the full-resolution original with zoom (wheel, buttons, shortcuts), drag panning, prev/next paging, filename caption and download, plus keyboard-arrow and touch-swipe navigation. One "image display control" popover next to the composer collapses every image in the conversation into a thumbnail grid whose column count (1-12) is configurable and remembered, or hides them entirely so the space closes up and restores them later; images are styled in place and no node is ever moved or reparented. The host-side display_image tool takes a local path or directory (TIFF/HEIC transcoded, originals still saved on download), a remote URL, or a keyword search over Bing, Huaban and Sogou that samples loadability before picking a source, re-saves images blocked by hotlink protection and drops dead links after a magic-byte check, returning paste-ready Markdown. It also keeps a system-prompt rule that every delivered image must appear in the reply body as  markdown, because collapsed tool rows are invisible to the reader.

Right-click menu for DeepSeek Harness conversation content: copy the selection or the whole message, copy message images and the preview lightbox to the clipboard as PNG (or save them), open file paths (absolute, relative to the session working directory, or ~/), reveal them in the file manager, open them with another registered application, and copy paths or links. Every candidate path is verified by the Host filesystem before an open action appears.

Draws circles, arrows, boxes and text on the DSH image preview, keeps every mark selectable so it can be dragged, scaled or re-edited later, and attaches the flattened PNG to the composer at the original image resolution.

Text-to-video and image-to-video generation via DashScope Wanx, Volcengine Seedance, Google Veo and OpenAI Sora, with tool results saved to the session workspace and a video gallery (grid, lightbox, download, delete) that survives DSH restarts.

A right-sidebar gallery of every image and video in your workspace, newest first, with thumbnails, type filters, search, and a lightbox.

In-chat image viewer for the web UI: takes over content image clicks (Markdown images, message attachments rendered as blob: URLs, and read_image results) and opens a dialog with pointer-centered wheel zoom and an editable percentage, drag pan, 90° rotation, download with progress, copy as PNG, open with the default app, and ←/→ gallery browsing across the conversation.

Generate images and videos directly in chat and deliver them to the conversation: generate_image / generate_video / send_media tools, a built-in Agnes free tier plus any OpenAI-compatible backend, background jobs that auto-push finished media, and inline gallery and video cards with download, lightbox, and native open.
