Plugins

Turns one plain-language request into a live workbench window: a sidebar panel asks a few clarifying questions, the model writes a single-file HTML artifact, and the plugin mounts it in a resizable floating window or a standalone browser tab. Declared window actions are recorded as info-level project journal entries (without their payloads), and workbenches can be imported, exported, or installed from a market index.

Interactive cards in replies, built from a fixed catalog of 31 components (sliders, inputs, sortable tables, charts, function plots, typeset formulas, tabs, checklists, flowcharts, quiz buttons, an animation player): controls recompute in the browser without another model call, and the model never writes HTML or JavaScript. Includes a calculus engine (integrals, derivatives, limits, sums, roots, Taylor polynomials) and a bundled skill that teaches the model when to use a card.

A temp note in the DSH right sidebar with session, workspace, and global scopes, browser-local autosave, one-click copy, and one-click LLM polish through the default model.

Local file manager served by the DSH web server itself: whole-disk browsing, previews for images, PDF, video and audio, text, Markdown, JSON, CSV, sandboxed HTML, docx and xlsx, Range downloads, folder ZIP, drag-and-drop upload, copy/paste, conflict-checked text editing, create/rename/delete-to-trash, and xlsx cell editing saved as a copy.

Global back/forward navigation for the DeepSeek Harness Web UI: remembers every session and whole-page panel you visit, shows a configurable 1-7 entry history strip you can click, and supports browser-style shortcuts plus mouse side buttons.

Opens STL meshes in the right-Sidebar document preview: binary/ASCII parsing in the browser, a WebGL viewport, and size, volume, surface-area and watertightness statistics.

Give DeepSeek Harness its own persistent computer: a bundled microVM with shell, browser, live view and approval gates

Operate the Chrome or Edge tab you are already in, through the unpacked extension: hover, coordinate clicks, drag, batched actions, whole-page screenshots, file upload, image addresses and switching between connected browsers — with approval-gated actions

Exports the plugin profile together with selected $DSH_HOME files and browser localStorage into one JSON, imports it back after a per-file preview, and can run pnpm install to reinstall the listed plugins; the format is interchangeable with the dsh-market profile backup.

Connects the DeepSeek Harness agent running on your own computer to the HarnessMate platform, so you can chat with it, exchange files and approve its tool calls from a phone or a browser.

Adds a right-column panel that compares a set of images the user picks from the workspace — 1/2/3/4/6 per page, per-image zoom and pan, the zoom and viewed position of one image synced onto the whole set, and a reorderable filmstrip. The browser loads every image, so none of it reaches the model.

Keyless web powers for any MCP client: web_search, JS-rendered web_extract over dual CDP Chrome with proxy failover, and 7 real-browser page_* tools in an isolated context.

Annotate pages inside the existing Harness Browser: click or drag to select, comment or ask, then send marked screenshots or DOM location details to the current session. While enabled it replaces the official Browser, Chat and Layout providers; targets Harness 0.2.1-alpha.2.

Chat with the DeepSeek web app (chat.deepseek.com) in a native DSH panel — a real browser drives the site on your existing web login, with streaming replies, deep-thinking and smart-search toggles, and image or document attachments. Conversations can be recovered from the web side, exported as Markdown, and distilled or replayed into a harness session, and the agent reaches the same web chat through six tools (dschat_status, dschat_send, dschat_stop, dschat_recover, dschat_import, dschat_transfer).

Keeps the current chat in a movable, resizable floating window when the right file or browser panel enters full view, with a compact input bar, a whale restore button and a return to the original split layout.

Gives an installed dsh web app a native-looking window caption through Window Controls Overlay - the manifest route is served with display_override, the app's own sidebar brand row and session header become the drag region, and the app's own trailing controls are inset clear of the browser's caption chrome.

Select text in the DSH web client and a translate button appears at the end of the selection; clicking it translates that text in place. Translation goes through the host llm service, so it reuses the model the current session already has selected and needs no separate API key; an OpenAI-compatible endpoint can be configured instead. The result opens in a popover that stays inside the viewport, with one-click copy, a row of language buttons for instant retranslation, and smart Chinese-to-English / other-to-Chinese as the default. Configuration is stored host-side and its API key is never sent to the browser.

Select a passage in a DSH conversation and read a plain-language explanation in a floating panel, which carries the surrounding message as the context. Three explanation depths (plain / general / pro) that re-explain on the spot when switched; optional web search and local file lookup (the model decides by default, and a button can force one lookup that reports only what is new); follow-up questions; and a button that hands the whole exchange to a new session in standby mode - the background is queued without waking the model or spending tokens. Settings live on the host in settings.json, and nothing is written until you press save. The repository also ships an OpenAI-compatible endpoint and a browser extension (source).

Drive the desktop and Chrome from DeepSeek Harness using the computer-use runtime inside the ChatGPT desktop application.

\!WARNING\! this removes the authentication step !WARNING! Exchanges the process launch token for the browser-session cookie, so a first visit needs no ?token=... in the URL.

Speaker button left of the model selector in the composer tool row — one click scrolls to the start of your newest question, marks it with a blinking caret and reads from there through the newest agent reply (dsh-tts, browser voice as fallback); press-and-hold the icon and then click anywhere on the page to pick another reading start position; press-and-drag-up opens a vertical mixer for in-page media volume and system output volume.

Connects DeepSeek Harness to the AdWhispr remote MCP server through mcp-remote with browser OAuth sign-in, adding tools for competitor ad research, ad creative cloning, and launching and managing Meta, Google and TikTok campaigns. Requires an AdWhispr account.

Replaces the shipped sidebar workspace browser with Recents, a project editor that adds extra source folders, and pin, rename, fork, and archive row actions.

Automatically group every DeepSeek Harness (DSH) Web GUI tab into one browser tab group. One package, two faces: the Chromium extension owns all grouping behaviour, and the DSH plugin mirrors it to a fixed path, detects it in the Web GUI, guides installat
