Plugins

A content-aware PDF reading plugin for vision models: profiles each page for figures (vector and raster), tables, formula risk and double-column layout, then applies content-aware hybrid extraction, rendering figure/table/formula pages as high-DPI region crops. Provides a low-resolution preview to understand the page layout, and renders a specified region at high resolution. Packaged as multiple tools for agents.

Inline preview for \[图片: path] image bridge markers: after the marker renders, the image shows in chat automatically, keeping long instructions out of the conversation.

Image viewer for the dock workbench: PNG, JPEG, GIF, WebP, BMP, SVG, ICO and AVIF, with SVG rendered as image data only.

Renders live multi-agent session activity as a pixel-art office in a Web UI side panel - each session is an ox/horse worker typing at its desk when busy or wandering off when idle, with click-to-view work monitors and in-place approval cards.

A desktop pet plugin for DeepSeek Harness (DSH): import Codex-style sprite-sheet pets and render them in the DSH Web GUI as a floating shell.overlay, with a pet library, interactions, and Agent-state linkage. / DSH 桌面宠物插件：导入精灵图序列帧宠物并在 Web GUI 悬浮渲染。

Markdown rendering for DeepSeek Harness sent user messages: every message bubble renders lists, code, tables, quotes and inline formatting through the host's own Markdown pipeline, while queues, previews and the composer keep their plain projection.

Web reading tools for text-only agents. Five read-only tools: web_fetch (any URL rendered as clean Markdown or plain text), web_links (inventory of a page's links), web_feed (RSS 2.0 / Atom entries), web_headers (HTTP status, response headers and redirect chain without downloading the body, HEAD with automatic GET fallback), and web_table (HTML tables extracted as structured rows with header detection and colspan/rowspan grid expansion). Transport is Node fetch plus a zero-dependency HTTP proxy implementation (CONNECT tunnelling, absolute-URI requests, NO_PROXY with suffix/wildcard/IPv4-CIDR matching, Proxy-Authorization). Zero runtime dependencies.

WeChat Official Account typesetting workbench: renders Markdown into inline-styled HTML you paste straight into the WeChat editor, with a sidebar panel, 11 themes and five model tools for block-level revision.

Renders HTML, React (JSX/TSX), Vue, SVG, Mermaid and Markdown written by the agent in an isolated iframe sandbox with SSE hot-reload, and adds a DOM click inspector, side-by-side visual diff, a responsive device matrix and one-click Vite ZIP export.

Page-level UI generation for DeepSeek Harness: design tokens (theme.json) and code standards (code-style.json) drive a dsh-fuse fence that renders whole pages, with spec pre-validation, a theme contrast guard, a pixel-level style inspector (getComputedStyle), undo history, and a settings UI.

Hebrew RTL rendering for the web GUI: per-block direction by dominant script, bidi-safe input fields, and RTL-aware Cmd+Left/Right line navigation.

Renders image, video, and audio paths and URLs from DSH conversations inline, with workspace-confined local reads and an optional ComfyUI proxy.

Hand a DSH web session to the locally installed Claude Code CLI: a per-session engine selector (DSH | Claude Code), Claude models and reasoning effort in the model seat, Claude permission modes in place of the access-mode selector, and permission requests, AskUserQuestion and ExitPlanMode routed to the native DSH approval, question and plan-review cards. The stream is written as native DSH session events, so the built-in transcript, tool cards and nested subagents render it; Claude slash commands merge into the command palette; the CLI is held by a detached broker, so plugin updates and DSH restarts do not interrupt a running turn.

Codex-style /btw command: answer side questions in a conversation-seeded subagent (fork provider), rendered in the UI without entering the main session history.

Markdown viewer for the dock workbench: GFM rendering with DOMPurify sanitization, document outline and relative-path image/link resolution, with one-click switch to editing.

Evidence-driven company and job due-diligence for DSH: logs sources with evidence levels, adds evidence-bounded claims, verifies the legal entity against official registries, and renders a PROCEED/VERIFY/STOP report with a verification checklist and interview questions.

DeepSeek Harness plugin that turns UI screenshots into implementation-grade web specs using OCR, deterministic geometry, scene graphs, assets, and render comparison.

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.

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.

Renders pasted/uploaded images inline in the DSH Web chat and gives text-only models vision: the model-invokable visual_review tool calls any OpenAI-compatible multimodal API first, falling back to a local Qwen3-VL worker.

**DeepSeek Chat (chat.deepseek.com) same-style attachments**: paperclip upload button, 240×64 DS-style file cards with official colored doc icons (PDF/DOCX/XLSX/PPT/IMG extracted from the DS frontend bundle), drag-and-drop, text extraction (PDF/DOCX/XLSX/TXT) injected into the message, and real attachment cards rendered in the transcript (custom user renderer) with the model reading full content.

Feynman learning-mode plugin: teach → teach-back → judge → re-explain loop rendered as rich HTML lesson cards (mermaid diagrams + shiki code highlighting).

Session execution analytics: steps, tool calls, failures, repeated actions, token usage and verification signals, rendered as text/Markdown/JSON reports.
