A modular office plugin for DeepSeek Harness

DeepSeek Harness (DSH) has released dsh-univer-office, a modular office plugin that enables the AI agent to create, edit, inspect, and deliver spreadsheets, documents, presentations, databases, and canvases. The plugin supports natural-language requests, live preview and approval of changes, and exports to standard formats such as .xlsx, .docx, and .pptx. It also allows importing and editing existing Office files, with all changes made in isolated worktrees for safe review and merging.

Give DeepSeek Harness the ability to create, edit, inspect, and deliver spreadsheets, documents, presentations, databases, and canvases. English · 简体中文 /dream-num/dsh-univer-office/blob/main/README.zh-CN.md dsh-univer-office is the Univer office plugin for DeepSeek Harness DSH . Tell the agent what you need and it can create or edit spreadsheets, documents, presentations, multidimensional tables, and canvases, or work with existing Excel, Word, and PowerPoint files. Every change is verified and stays in the conversation for you to preview, approve, or discard. After installation, describe the result you want in natural language. The agent handles creation, editing, and verification while you follow the work live and review the result in the conversation. Deliver spreadsheets as Excel .xlsx , documents as Word .docx , and presentations as PowerPoint .pptx files when needed. The agent created this spreadsheet from a natural-language request, then added conditional formatting and a chart in the same conversation. The result can be previewed, revised, merged into the current version, or discarded in place. Deliver a standard Excel file:after review, ask the agent to export the spreadsheet as .xlsx so it can be opened and edited in Excel, WPS Office, and other compatible office applications. See the complete workflow from request to review Give the agent a topic, audience, page count, content outline, and visual direction. It can build the complete presentation, verify content and layout page by page, and leave the result in the conversation for review. Deliver a standard PowerPoint file:after review, ask the agent to export the presentation as .pptx so it can be presented and edited in PowerPoint, WPS Office, and other compatible office applications. See the presentation workflow from request to finished deck Analyze and build spreadsheets — read or create Excel data, clean fields, write formulas, apply formatting and validation, create tables, charts, pivots, filters, sparklines, conditional formatting, and images, then export the result as .xlsx , .csv , or .tsv . Write and lay out documents — create paragraphs, rich text, lists, tasks, tables, images, charts, headers, footers, pagination, and page layouts. Create and revise presentations — generate a deck from an outline, redesign selected pages, edit text, shapes, images, tables, charts, and transitions, then detect off-page, overflowing, and overlapping text. Build lightweight databases — create Base tables, fields, records, and views with formula fields, filters, sorting, grouping, and Sheet-backed references. Draw editable canvases — create shapes, text, connectors, images, native charts, and diagrams, with connector and layout analysis. Compose several content types — one .univer file can contain Sheet, Doc, Slide, Base, and Board Units. Formulas and embedded content can reference other Units in the same file. Work with Office files — import .xlsx , .csv , .tsv , .docx , and .pptx , then export the edited content in the matching format. Review agent changes safely — every write starts in an isolated worktree. Watch changes live, then merge or discard them from the conversation instead of letting the agent overwrite the current version. Create a simple payroll spreadsheet with employee, base salary, bonus, deduction, gross pay, and net pay columns. Calculate the totals automatically. Create a six-slide lesson deck about bubble sort. Explain the concept, each comparison pass, pseudocode, and complexity, and check every page for layout problems. Create a formal weekly project report with an executive summary, this week's progress, a risk table, next week's plan, headers, and footers, then export it as docx. Create a customer-tracking Base with company, contact, stage, expected value, and next action fields, plus a view grouped by stage. Create a sales Sheet and a summary Slide in the same .univer file, with the Slide chart reading the Sheet data. | Content | Create and edit | Verify and review | Import | Export | |---|---|---|---|---| | Sheet | Cells, formulas, styles, tables, charts, pivots, filters, validation, images, and more | Structured range inspection, recalculation, live preview | .xlsx .csv .tsv | .xlsx .csv .tsv | | Doc | Paragraphs, rich text, lists, tasks, tables, images, charts, headers, footers, pagination | Document readback, live preview | .docx | .docx | | Slide | Pages, text, shapes, images, tables, charts, SVG layouts, transitions | Structure inspection, text bounds/overflow/overlap lint, live preview | .pptx | .pptx | | Base | Tables, fields, records, views, formulas, filters, sorting, grouping | Facade readback, live preview | .xlsx .csv .tsv | .xlsx .csv .tsv | | Board | Shapes, text, connectors, images, native charts, routing | Element and connector analysis, live preview | mermaid | .png .jpeg .pptx | Every content type supports isolated worktree editing, review submission, reopening, merging, and discarding. Base and Board currently use exact Facade readback for structural verification. Board file export is not yet supported. If DSH is running, first press Ctrl+C in the terminal that started it. You can run the installation command while DSH is running, but the current DSH process will not load the new plugin automatically. Install the plugin from npm: dsh plugin --profile web add dsh-univer-office Restart DSH after installation: dsh web After DSH starts successfully, refresh the existing DeepSeek Harness browser page with Cmd+R / Ctrl+R . Create reports/q2-review.univer. Read data/q2-sales.xlsx and build a management dashboard with summary metrics, monthly trends, and regional rankings. The agent automatically loads the relevant skills and selects the univer tools. A typical task creates the file and a worktree, imports or creates a Unit, edits it, reads the result back for verification, and submits the worktree for review. - Creating a .univer file, creating or reopening a worktree, writing content, and submitting for review opens a live window in the top-right. A non-terminal worktree left open in one turn stays open in the next. - Every touched .univer file that still exists at the end of the Turn uses the same foldable, fullscreen-capable Turn card; historical Turns keep the same card collapsed by default. Temporary files created and then removed during the Turn do not leave cards behind. - Submit, merge, and discard through the full Univer page embedded in the card instead of duplicate controls outside the Viewer. A .univer file is a composable office container that can hold several Units of different types. The plugin puts each agent task in an isolated worktree: Your request ↓ Load the matching Univer skill ↓ Create / import / edit in a draft worktree ↓ Readback + recalculation + Slide layout lint ↓ Live preview and in-conversation review ↓ Revise / merge / discard Only merge and discard end a worktree, and both require an explicit user request plus DSH approval. ready only submits the worktree for review; it does not change the trunk. You do not need to call tools manually in normal use; DSH selects them from your request. This list shows what the plugin exposes to the agent. | Tool | Purpose | |---|---| univer new | Create an empty .univer file without overwriting an existing file | univer status | List Units and worktrees in trunk or a selected worktree | univer worktree | Create, submit, reopen, merge, or discard an isolated worktree | univer unit | Create or remove a Sheet, Doc, Slide, Base, or Board Unit | univer import | Import an Office file as a new Unit | univer inspect | Read document structure or a selected Sheet range | univer execute | Read or modify content with the exact Univer Facade API | univer export | Export a Sheet, Doc, Slide, or Base Unit | univer lint | Detect off-page, overflowing, and overlapping Slide text | univer compile svg | Compile SVG into an explicit Slide page with real font metrics | univer api | Search the exact Univer Facade API bundled with this plugin | The plugin also ships eight version-matched, lazily loaded skills: core orchestration, Sheet, Doc, Slide, Base, Board, Embed, and cross-Unit formulas. Live Univer window — file creation plus worktree creation, reopening, writing, and submission open it automatically. Drag, resize, fold, or maximize it; non-terminal windows left open carry into the next Turn. Unified Turn cards — every touched .univer file that still exists has its own full Univer card, later reads do not erase a lifecycle result already produced in that Turn, and deleted temporary files do not leave loading cards behind. Historical review — draft, ready, merged, and discarded results all remain in the same card layout at their original Turn, with historical cards collapsed by default. Session isolation — each DSH session shows only its own windows, cards, and review state. English and Chinese UI — the plugin shell and every open Viewer follow the DSH locale. - DeepSeek Harness and Node.js =22.19.0 . - Slide layout lint and real SVG text measurement require a local Chrome/Chromium executable. Set UNIVER RENDER BROWSER to use a specific browser path. - The plugin does not currently expose screenshots to the model. Structural and layout checks are not a substitute for pixel-level visual approval; you can still inspect the result in the live Viewer. - Slide master pages, layout pages, and speaker notes are outside the current editing scope. - Board mind maps, tables, ink, advanced editing, and file export are not yet supported. The defaults are designed for local use: the Gateway starts on the first file-state request at 9080 . If that port is occupied, it tries 9081 , then continues upward one port at a time. Configure the bundle's Cordis layer when you need different values: | Field | Default | Purpose | |---|---|---| gatewayPort | 9080 | Initial loopback port for the bundled Gateway; occupied ports advance by one | autoStartGateway | true | Start the Gateway on first use | gatewayStartupTimeoutMs | 10000 | Gateway startup timeout | gatewayRequestTimeoutMs | 3000 | State-read timeout | gatewayMutationTimeoutMs | 60000 | Gateway mutation timeout | unitContentOperationTimeoutMs | 120000 | Import, export, inspection, and execution timeout | tools | true | Register the univer tools | skills | true | Register the bundled Univer skills | See src/host/config.ts /dream-num/dsh-univer-office/blob/main/src/host/config.ts for the remaining cache and commit-confirmation options. dsh plugin --profile web remove dsh-univer-office This project is a standard DSH bundle https://github.com/deepseek-ai/deepseek-harness/blob/main/docs/user/develop/basic/publish.md .
