Plugins

Mic button in the composer tool row: Web Speech API speech-to-text (Chrome/Edge), language switching, and optional auto-send, zero dependencies.

Host-side Typert remote for dsh-tool-writing: serves project volumes, chapter status, corpus library, full-text search, evolution entries, and thread-graph data to the client writing panel.

Client-side writing panel for the Web UI: project volumes and stats, corpus library, full-text search, evolution version-chain diffs, and an SVG thread graph, shown only in writing-preset sessions.

11 shareable workflow skills (handoff, triage, to-spec, to-tickets, wayfinder, teach, wait-what, dsh-mode-routing, ask-matt, overnight-execution, full-throttle) as an installable skill pack.

Search, list and read past and current sessions through the harness's own `sessionQuery` service: uses the SQLite FTS5 index where a deployment enables it, and falls back to a bounded newest-first scan where it does not.

DSH plugin: drive PhotoCraft (raster image editing) headlessly through its own CLI and MCP server.

Chinese industry and technology research report skill with an offline DOCX build pipeline (build_docx.py). Enforces a 9-chapter structure with a plain-language timeline (Section 2.1), 5-dimensional technical bottleneck criteria, and Make-vs-Buy cost/compensation trade-offs, verified by check_threads.py and compiled to .docx with a 3-level auto TOC. Requires Python 3.9+ with lxml.

Six-layer local memory for dsh: captures turns, stages them through an L2 buffer into DL3 summaries via a staging model, injects a stable memory block each turn and replaces chat history with placeholders. Ships five memory tools and a config page.

DSH plugin: native browser_* tools that drive the Chrome you are already using, over native messaging + CDP. No WebSocket, no port, no Connect button. The native host and the MV3 extension ship inside this package and are installed automatically on first

Control the Chrome browser you are already using: open new tabs or reuse your logged-in tabs, so the model can read pages, click, fill inputs, drag page elements, scroll, take screenshots, open tabs in groups and close the tabs it opened, inspect console and network logs, and debug the browser. Requires Chrome 120 or newer; install the extension from the Chrome Web Store and pair it with an 8-digit code.

Connects Tencent CodeBuddy CLI to DeepSeek Harness through ACP, with native CLI tool execution, multi-account management, and a standalone codebuddy_ask tool.

Performance optimization and smoothness enhancement for DSH Desktop (renderer-side only; host code untouched, no on-disk config): skips offscreen message rendering, stops frames and timers while the window is hidden, lazily loads media, coalesces session-list repaints and pre-warms large session files; shows the measured main-thread saving in settings. A lightweight speed-up for lag, dropped frames, slow large-session opening and background CPU use.

AI video creation and editing inside DeepSeek Harness, with conversation-driven revisions, multitrack timelines, audio waveforms, and MP4 export. Requires Node 22, FFmpeg and Chrome; audio generation calls a Qianwen MaaS endpoint only after you add an API key.

Context indicator for the DeepSeek Harness composer: segmented occupancy, compression points, and the native auto-compaction line (flashes red when crossed). Supports preview-then-confirm compaction (/bc), seamless handoff (the old session becomes "History N" while the new one keeps the name; a relay bar above the composer shows the full handoff chain with two-way jumps), and message pinning with stale-pin labels. Thresholds, colors, and auto-archive after handoff are configurable in Settings.

Fixes plugins a DSH upgrade left behind: rehearse each rejected plugin in a throwaway home, grant a reversible exact-version exemption when it boots, and refuse when it does not. Also a multi-host compatibility matrix, a public table of every catalogued plugin, and a read-only plugin_health tool.

Union web search for DSH (consolidated successor of DDDMUC/dsh-free-search, which it credits): 28 engines across three tiers — keyless free (Bing/DuckDuckGo/AnySearch/SearXNG multi-instance union, plus Exa/Tavily/Keenable/Firecrawl/Parallel keyless modes), paid-with-key (Zhihu/Perplexity/Serply/DeepSeek official/You.com/Baidu/Kimi/Aliyun/Doubao/Zhipu/Bocha/Metaso), and model built-in search (OpenAI/Gemini/Claude/Grok, explicit opt-in only) — with auto smart routing, per-engine enable/disable & fallback priority, parallel top-3 merge, multi_search, failure-aware fallback, a toggle to block the system built-in search, time filtering, platform search, web_fetch and a web settings UI. Experimental free advance_fetch: whole-page GFM-Markdown or CSS-selector/fields structured extraction with no API key and no per-call billing; fetch identity configurable (custom User-Agent, Referer, per-domain cookies attached only on domain match, never leaked across cross-domain redirects). Hosts 0.1.0-rc.2 through 0.2.1-rc.2 (17-tag exact engines.dsh enum; the rc.2 search-provider takeover goes through volatile config pinning after capability probing, never version branches). Paid engines need your own API keys (optional; free engines work keyless). npm: @drscrewdriver/dsh-union-search and bare dsh-union-search.

Locks the model's reasoning, replies and tool-call descriptions to a chosen target language (Simplified Chinese by default) with system-prompt sections at the head, middle and tail of the prompt, offering three strength levels, an auto mode that follows the DSH interface language, a settings panel that shows the language currently in effect, and a sidebar quick switch.

Watches a turn for long silences and, once the threshold passes, injects a user message asking the model to state in prose what it is doing before carrying on, so the turn keeps going. The same text is mirrored in a lower-left overlay above the composer. The silence threshold and the minimum gap between reports are set in minutes, the prompt can be replaced wholesale, and it runs with no runtime dependencies. Requires DSH 0.2.1+ and Node.js 18+.

Turn another computer into a remote Agent teammate: the worker runs its own DSH and a full Agent loop locally, so dispatched tasks keep running when the link drops and its model credentials never leave that machine. The hub dispatches through 8 remote_* tools, receives only a handoff summary plus an artifact manifest, and pulls finished products on demand — intermediate artifacts stay on the worker. Pairing-code onboarding, direct or relay transport for NAT, Web panel on both sides.

Read-only Git panel for the current workspace — branch, changed files, diffs and image before/after compare — plus three capsules above the composer (Git status, tool and skill activity, session running time) and per-session change attribution with review progress.

Finishes 头歌 (EduCoder) homework over the platform JSON API, with no browser automation. educoder_sweep scans every course for homeworks that still have unfinished challenges — complete homeworks are skipped without reading a single challenge, so a full-account scan costs no model tokens — and can finish them; multiple-choice challenges also cost no model tokens, because the platform returns the answer key in any submission response, while code challenges are generated by the model, uploaded with evaluate:0 and graded once per challenge, then retried using the error report the platform returns. Three tools: educoder_sweep, educoder_homework, educoder_account.

Category tree for the DSH sidebar workspace browser: workspaces and their sessions nest under user-made categories (collapsed state remembered), rows drag between categories, a new workspace can be created straight into one through the directory picker, categories rename and delete in place, sessions archive and unarchive from their own row (the built-in browser's stop-active-work confirmation included) alongside a hide / show / only-archived filter, row buttons carry the app's own hover tooltips, and a footer toggle switches the panel back to the built-in list.

Expert roster for DeepSeek Harness: 636 experts across 22 divisions with full Chinese names and bios, summoned as subagents from the @ menu or by the model through list_t_experts / summon_t_expert / summon_t_experts, plus custom experts and a skill on/off switch.

Turns each long dsh conversation into a three-level trail (topic to progress steps to milestone timeline) and shows it in a draggable overlay, where one click jumps back to the matching message in the transcript. Topics are distilled by the DeepSeek model with a zero-cost rule-based fallback, can be renamed, locked, merged by drag and drop, and support per-conversation notes plus a vector drawing board.
