Plugins

Message timeline rail for DeepSeek Harness web chat: evenly spaced ticks for each user message on the right edge, click to jump, hover to preview.

Transactional data-only configuration pack manager with integrity, ownership, preview, diff, and rollback safeguards.

Design Studio tab: design briefs become html/css/js mockups with live preview, element picker, design-agent chat with vision review, identity presets and zip export.

Browse and manage the community plugin catalog from a first-level DeepSeek Harness Settings page, with verified installs and updates, removal, pause and resume, installed-package state, and sanitized README previews.

Adds a produced-files card row to the chat and a resizable split-screen preview panel for workspace artifacts (Markdown, source code, CSV, JSON, images, HTML), plus a localhost port preview.

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.

Deep-collaboration writing agent for DSH: per-user writing-style learning from edit pairs, clarify→outline→section-writing→red-team→reader-gallery flow, project-to-report synthesis (lab report / product intro / survey / README), 41 MCP tools, and web selection-improve UI with in-app file preview.

DSH Web skin manager for mainstream DSH skin packages: import local paths or GitHub collections, scan installed skins from the web profile, preview/use/disable/refresh/delete, with host-side persistence.

Floating workspace file-tree browser for the Web GUI with line-numbered syntax highlighting and Markdown preview.

Google AI Studio-style floating preview for the Web UI: a draggable/resizable iframe preview with aspect-ratio and resolution presets, plus a VS Code-style code window with direct editing, confirmed writes, and session-log recording.

Line-range selection: browse workspace files, preview code with line numbers, visually select a line range, and write a `@path:start-end` reference into the composer; the agent receives the exact selected lines on send.

Tick-rail conversation navigator: one tick per message you sent, a lit peak that follows the mouse with an even falloff, hover previews, click or keyboard to jump.

Left-edge turn-marks strip in chat: one bar per user message, click to jump to that message, hover for a preview, active bar turns white.

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.

Read-only Git and SVN change preview for DSH

Creates local, content-addressed workspace checkpoints with diff previews and two-phase restore confirmation.

Standalone DeepSeek Harness plugin: preview .drawio (mxGraph XML) diagrams in the Web Sidebar

Preview native WeChat Mini Programs in the DSH sidebar with a local runtime and WXML source locations.

Version-control workbench for the DSH Web sidebar: local changes grouped by type, per-file and multi-file staging, preview-confirmed commit / update / push, and a failure dialog that shows the raw Git output instead of a four-second toast.

Auto-archives sessions idle beyond a configurable threshold, with safety guards (never touches live or running sessions), plus a full archived-session management UI: list, unarchive, safe delete and content preview.

Quick-open palette for the Web GUI: Ctrl+P fuzzy-searches an in-memory index of the session workspace (about 51k entries, median query 5 ms) with per-segment path anchoring, dir: and file: prefixes, Tab directory drilling and :line jumps, opens the picked file in the native right sidebar, and drops a file reference into the conversation draft with Ctrl+Enter. Also adds in-file find (Ctrl+F) and a selection-to-reference action to the built-in file preview.

Shared engineering skills, a read-only memory-bank dashboard with SQLite audit guidance, and workflow request previews for DSH.
