Docs & Rendering

Generate validated, self-contained interactive architecture, workflow, sequence, data-flow, and lifecycle diagrams from repositories or system descriptions.

Give DeepSeek Harness a real office environment. Univer Office Plugin brings spreadsheets, docs, slides, canvases, relational tables, and more into one runtime — with connected data, validation, versioned changes, and isolated worktrees for multi-agent collaboration.

Expose MineRU document parsing tools to the model.

Deterministic industry research reports for DeepSeek Harness — company and industry research flows produce structured, verifiable reports from staged evidence.

Workspace-safe Office tools for agents: create/read Word, create/read/update Excel, and create/read PowerPoint decks with PNG/JPG/GIF image placement.

Connect multiple Overleaf projects to DSH through OverleafMCP for browsing, analysis, and Git-based file updates.

Render Mermaid code fences in DSH Web chat messages as lazy-loaded SVG diagrams with strict sanitization and light/dark theme follow.

Editable Excalidraw diagrams for DeepSeek Harness conversations.

Document reading mode for DSH.

Create, read, and edit PPTX, DOCX, XLSX, and PDF via the local zagens-office CLI as office_schema / office_write / office_edit / office_read tools.

Bounded, cell-addressed `doc_read`/`doc_write` for xlsx / pdf / docx / pptx / ipynb, plus an MCP server and CLI.

DeepSeek Harness Web plugin — PDF text-layer and scanned-PDF OCR, Office docx/xlsx/pptx to Markdown, TIFF/epub and long-document index cards.

Markdown sidebar preview and source editor for dsh-better-sidebar, with block- and text-range annotations that can be sent to the conversation as structured revision requests.

PDF document editing plugin for precise text editing in PDF files.

HTML↔Markdown conversion, GFM table normalization, and TOC generation.

Overleaf-style LaTeX paper workbench: annotate any text in the rendered PDF and let a dsh agent revise the sources with compile checks and git history.

Technical documentation agent preset for DeepSeek Harness: template-driven writing with a self-learning template library, AI-flavor removal for tech docs, and a quality-assurance toolkit (document audit, cross-document consistency, numbering resequencing, version sync, PDF and Word export, screenshot automation).

Turn raw data (CSV / pasted table / SQL results / DuckDB) into a structured Markdown report with business conclusions, metrics and charts.

In-chat preview for produced files: click a produced-file chip to render Markdown (server-side markdown-it + highlight.js), images, or plain text right in the conversation; system-app open and reveal-in-folder stay one click away.

Dockable Markdown preview for the DSH Web UI: side-by-side with the conversation, a per-session recently-read .md list, local relative-path images render in place, and clicking an in-chat .md reference previews it instead of launching the system editor; follows the shell light/dark theme.

Render Mermaid code fences as SVG diagrams with streaming support, diagram/code switching, fullscreen zoom and pan, SVG export, and a bundled same-origin runtime.

Preview Mermaid diagrams as images via local rendering in DSH Web when the chat message contains a Mermaid fenced code block, and also allow integration with external rendering servers.

Offline mirror of the official DeepSeek Harness documentation as a dsh skill: 168 site pages (EN/zh) plus 52 repository-only reference docs, with topic navigation and a full-text search index for plugin development.

Writing bridge to the open-source QingAgent client: the agent drafts and revises documents through qing_ prefixed host tools, typeset on a rice-paper panel with mermaid, drawio, tables and KaTeX; edits stage as reviewable diffs and land only on commit, and it requires the QingAgent desktop app on the same machine.

Context7 MCP bridge: gives the model up-to-date, version-specific library documentation and code examples through the Context7 MCP server, keyless by default.

Package and install code-server (the web version of VSCode) as a plugin within dsh to quickly achieve professional file editing.

Render Markdown to a standalone, self-contained HTML page: an `md_html_render` tool that works in a headless profile, plus a web drawer to browse, preview, edit and export local `.md` files; both share one renderer, with no runtime dependencies.

Mermaid diagram renderer for the Web UI conversation: renders mermaid code blocks into interactive cards (zoom, fit-width, fullscreen viewer, preview/code toggle) with official UI primitives, and keeps the original code block with an inline error banner when rendering fails.

Browse, preview, edit, and save files under the current project's openspec/ directory from a Web UI header panel that follows the session workspace.

PDF parsing tools for DSH: pdf_info, pdf_extract_text, and pdf_render_page with dual pdfjs and built-in rendering engines, including system-font rendering for PDFs with non-embedded CJK fonts.

Presentation skill and tools: one sentence or one document to an HTML slideshow plus editable PPTX, with five built-in themes, default theme/language config and bilingual support.

Publish TXT, Markdown, HTML, PDF, Word, and PowerPoint files as ShareOne links with passwords, watermarks, text-page updates, and TXT/Markdown/HTML comments.

Registers the Inspiration Deck Workshop skill for DSH: local static HTML presentation decks (6 deck templates, 25+ layouts, 23 themes & motion showroom) with a validate + PNG/PDF export CLI and smoke tests, zero runtime dependencies.

Renders mermaid/mmd code blocks in the conversation as chart cards with preview/code toggle; the engine is inlined so it works fully offline with no CDN (npm: `dsh-mermaid-render`).

Obsidian-style Markdown workbench for DSH: browse, edit, preview, create, move, and delete notes inside the selected local vault.

Registers the remove-pdf-background-gray skill for DSH: whitens gray/off-white scan backgrounds in image-based PDFs while preserving resolution, page geometry, and anti-aliased text edges (lossless Flate write-back), via a single Python script (pypdf + Pillow + numpy).
