Unified search with evidence verification for agents: 120+ engines with multilingual routing, vertical domains and structured modality cards, 10 MCP tools plus wide_research orchestration, and a fetch-verify loop that backfills evidence scores.

Let DeepSeek Harness see and operate any program on Windows. The model looks at the real screen and drives the mouse, keyboard and windows itself. It is fast: several steps run in a single round trip, and a window can be focused before input lands, so the click hits the right one. It can do anything you would do on a desktop, including but not limited to CAD drawing, circuit simulation, and sending messages.

Search built for agents: multilingual coverage across web, academic, code, shopping, finance, news, and encyclopedias.

Research-assistant plugin suite (literature search, research wiki, LaTeX compile, independent subagent review) for the DeepSeek Harness

Zotero as an evidence store for agents: search your library, inspect metadata and notes, retrieve evidence passages, open source PDFs, and generate citations and bibliographies.

Academic assistant plugin.

Academic writing guard (EN/ZH bilingual): removes AI-style defensive writing, protects scientific evidence (numbers, citations, claim strength, null findings, scope) during polishing, and calibrates writing toward a target journal (Journal Profile + Journal Fit). Deterministic local regex/statistics, zero network/LLM; writing_rules / writing_audit / writing_style_profile / writing_journal_profile with auto-audit on paper writes.

Installs four multi-agent math-research presets for DSH: v2 (probability-driven pipeline with multi-verifier debate), v3 (paper-style Markdown knowledge base with a planner agent and a reusable method library), v4 (persistent self-organizing residents that message and meet), and v5 (a research institute with an academician who decomposes and assigns work, voting researchers, temp workers, group chat and a compare-and-set task board); all four support checkpoint resume, human intervention, and an optional Lean formal-verification switch (off/encourage/require) whose passing proof turns the vote into a fidelity check of the Lean statements.

AI4Scholar academic search: 38 tools over Semantic Scholar, PubMed, Google Scholar, arXiv, bioRxiv/medRxiv, and DOI resolution (search, citation graph, authors, recommendations, PDF full text in slices, auto-cite, scientific figures), a unified cross-platform search with de-duplication, an API-key card in Settings, and per-call credit accounting with an `/ai4scholar` balance card.

Side-panel arcade: 18 offline mini-games to play while the model thinks.

Views and builds CAD models (STL, OBJ, STEP, IGES, DXF, SVG) via cad_view/cad_info and OCCT parametric modeling tools, with an interactive viewer card and a resident CAD panel in the Web UI.

Ported from the ARS Claude Code plugin (44k+ stars on GitHub): academic research skills for DeepSeek Harness — a deep-research agent team, a paper-writing pipeline, a multi-perspective peer-review panel, and an end-to-end orchestrator, plus sixteen /ars-* commands.

DeepSeek Harness bundle registering one skill that turns long-form production (academic papers, industry analysis, business commentary) into a 9-role pipeline: T1 literature / T2 data / T3 case scouts running in parallel, T4 analyst, T5 writer, T6 critical companion, T7 auditor, T8 finalizer run by the coordinator, T9 peer reviewer — across 6 phases with triangular evidence verification, a 26-check M-gate (25 scripted checks plus one human checkpoint), a G0-G16 audit including a Chinese AI-trace gate, peer-review scoring with journal matching, and 4 human checkpoints. Installs with `dsh plugin add lunheng-article-pipeline` (package.json#dsh.bundle.patch plus a lib/index.js entry that registers the skill); ships role cards for T1-T9, templates and 36 zero-dependency verification scripts, with five-language READMEs.

AI-for-Science research workflow skill for DeepSeek Harness, aimed at researchers and grad students using agentic AI: multi-angle literature review with per-angle files, experiment design with a caveat list, figures and paper reading; each job returns files plus a cross-verification brief for a second model. Zero deps, MIT.

Research Agent skills, literature search with citation tracking, document-to-markdown knowledge base builder, and in-depth reading with browser workbench for DeepSeek Harness.

Curated research plugin market: adds a Research plugins page to Settings with hand-reviewed plugins for literature search, reference management, writing and workbenches — one-click install, update and remove pinned to the reviewed version, restart from the panel, and exactly one network request (its own catalog).

Manage conversation records from the DSH web GUI settings page: delete a whole session (archive plus physical log removal) or a single message (deleting a user message cascades to its assistant replies and tool results). Running and current sessions are protected.

Registers two MCP servers that drive the installed AutoCAD and SolidWorks desktop apps over COM, plus two on-demand skills. Windows only, Python 3.11+; the pinned upstream servers install themselves on first load, and only the sides whose CAD application is registered get a row. Each server advertises two meta-tools instead of its full catalog (a discovery shim here for SolidWorks, upstream DISCOVERY_MODE=search for AutoCAD), taking the schemas loaded before the first request from 23,404 to 256 tokens and from 83,732 to 365 respectively.

Prose-editing skill for academic and professional writing. The composer offers three modes: Check — review and suggest without editing, with a verdict when readiness is asked; Polish — improve the wording while keeping the meaning, facts and citations; Draft — draft from the supplied material without adding facts.

Caddy forward_auth administrator login for DeepSeek Harness Web, with Argon2id passwords, revocable sessions, bilingual UI, and a native sidebar sign-out action.

Windows KiCad 10 IPC FreeRouting adapter with live editor preview and transactional final import

Heap-allocated stack-safe fork tree with two-track indentation, title marquee, and physical cascade purge.

Exposes Cue public data MCP services to DeepSeek Harness: 15 streamable-http domains (~104 tools) for regulatory, macro, disclosures, statute, holdings, entity, academic, IPO, ESOP, buyback, footnote and fact-index data as native mcp__cue_<domain>__* tools.

Academic writing toolkit for DSH agents: paper outlines, title and abstract skeletons, GB/T 7714 / APA / MLA citations, phrasing QA, and a pre-submission checklist.
