Skill that fact-checks a claim against the open web rather than model memory: it splits the claim into independently checkable fact points, routes each point to the primary-source ladder for its domain (policy, academic, medical, financial, disaster and accidents, food safety, science, education, sports, entertainment, judicial, and more), searches domestic and international ecosystems in parallel, fetches primary pages, grades sources by type, re-searches with debunking keywords, and reports conclusion-first with a full URL and citation position behind every statement, keeping unverified and undecidable points separate from confirmed ones. Three factual judgements can be routed to a TypeSafe Jev (System One) decision model when a key is configured, falling back to the skill's deterministic rules when it is not; a model verdict can only lower a confidence tier.

Drive CADCraft from the agent: draw lines, arcs and splines, manage layers, add dimensions, hatches and blocks, then export DXF, DWG, SVG, PNG or PDF. Exposes both CADCraft's command ids and its own MCP server, so a drawing can be created and read back. Requires the matching ArtCraft app CLI installed locally; it is not bundled.

Academic tools in TypeScript, no Python or MCP server: the Zotero library through its local API or zotero.org (search, annotations, full text, citation export; add by DOI / arXiv id, notes and tags when writing is turned on), starting Zotero when it is closed; paper search across arXiv, OpenAlex, Crossref, Semantic Scholar, PubMed and Europe PMC, plus CNKI and Google Scholar through a browser window; open-access full text, citations from the DOI registry, reference checking; 11 bundled skills.

Delete a session from the UI (session-header button or sidebar row menu) or with the session_delete tool: stops and releases a running agent and its live session first, then removes the log directory, projection cache and workspace accounting, and cascades into the subagent sessions it owns while leaving forked branches untouched.

Adds a 3D model library in its own conversation tab, where agents store models built from CadQuery scripts or supplied as tessellated meshes; the library previews them with three-cad-viewer, organises them into folders and exports them to 10 formats including STEP, BREP, STL and DXF.

Academic literature search and citation tools for DeepSeek Harness: paper search via Crossref and OpenAlex with no API key, related-works discovery, and citation formatting in GB/T 7714, APA and BibTeX.

Reads and edits STEP models through FreeCAD, measures geometry (distance, angle, diameter), and generates first-angle 2D machining drawings with a hole table as SVG, DXF, PDF or PNG.

Connects the hosted Knowra MCP server: search arXiv papers by topic, author or exact UTC dates without an account, and sign in with OAuth from the plugin page to read Scout reports on methods, evidence and limitations.

Eight academic skills bundled for one-command install — publication-ready academic figures designed from real data with visual review, AI-text humanization, paper polishing and rewriting, PubMed citation verification (DOI/PMID reconciliation), Chinese citation and medical-book reference checks, and WeChat medical article structuring. Three skills run fully local, five call external services only when used (NCBI E-utilities, DOI resolvers, publishing platforms), declared per skill. Zero telemetry, no install-time scripts. Skills run local Python 3.8+; the academic-figures skill also needs its pip dependencies installed.

Local-first academic assistant: event-sourced courses, tasks, plans, reminders, course materials and 23 DSH tools.

DSH sidebar and panel for courses, tasks, plans, connections, course materials, automation and settings.

NURBS BRep solid modeling studio with natural-language input, live 3D viewport (measure/wireframe/fit), STEP export, and agent tools driving NVIDIA usd-brep through a managed CPython venv. Needs CPython 3.12; usd-brep wheels cover 64-bit Windows and Linux only.

Floating, browser-local whale arcade with three score games and ocean-themed Gomoku for breaks while waiting on the agent.

Password gate for the DeepSeek Harness Web UI that also removes the 403 a reverse proxy causes, with revocable sessions, an admin page and zero dependencies.

Turns one journal paper PDF into a Chinese group-meeting literature report deck (.pptx) in the Nanyang Normal University physics template, plus a matching Word speaker script. Requires Python 3 with python-pptx, python-docx, Pillow and pymupdf (pypdf fallback); install them with pip install -r requirements.txt.

Adds right-sidebar document previews for STL, OBJ, PLY, glTF and GLB models, zip/tar/gzip archives, audio and video, fonts, subtitles, TOML, Intel HEX, JCAMP-DX spectra, VCD waveforms, KiCad schematics and boards, and DFU firmware images.

Drives Siemens NX 2406 and 2506 from DeepSeek Harness, plus NX 12: an executor that judges a journal run from its log rather than its exit code (NX returns 0 for a journal that swallowed its exception, and 0xC0000409 after a clean one), 16 typed tools over a resident batch NX, and a probe that keeps the three releases apart. Windows only; NX 2406 is the reference release, 2506 expected. Requires a local Siemens NX install and a free NX licence seat; run `dsh-nx install` once, and the 16 MCP tools stay off until `NX_ENABLE_MCP=1` is set (the skill route works without it).

DSH plugin to read AutoCAD DWG/DXF, PDF and images without installing AutoCAD or Tesseract; DXF requires Python 3 and ezdxf on the machine.

Drives the installed AutoCAD over COM and exposes it to the agent as 18 mcp__autocad__ tools: connect and status, cancel the current command, list registered ProgIDs, list or create documents, save, create and list layers, draw lines, circles, rectangles, polylines, arcs and text, list entities, zoom to extents, and pass any native command through. A sidebar panel owns the Python bridge process — start, stop, restart, dependency bootstrap, live logs and crash recovery — and resolves every path at runtime, so the same bundle serves both the web app and the desktop app. Windows only, Python 3.10-3.12, AutoCAD 2022-2024 documented (2024 is the default; other versions require setting CAD_PROG_ID to the matching ProgID).

A neon pixel theme for DeepSeek Harness desktop with playable air-battle, pig-sling and fruit-slicing backgrounds, mouse controls and a day/night switch for the sling game.

Connects DeepSeek Harness to a local SolidWorks install through an MCP server, with a read-only default mode and per-call confirmation for high-risk operations. Windows 10/11 x64 only; needs Python 3.10+ with mcp, pydantic and jsonschema (plus pywin32 and comtypes on Windows) and a local SolidWorks 2023-2026 installed and started at least once.

Scientific figures as code: agents create a versioned figure IR, patch it incrementally (one node at a time — untouched objects never move), and export publication-ready, true-vector SVG / PDF / PPTX. Seven papercanvas_* tools (create, get, patch, layout, lint, render, inspect) over a deterministic engine with FC001-FC008 quality lint and CJK-aware font resolution. Verified on DSH 0.1.5-rc.3 through 0.2.2-alpha.2. By the author of dsh-sessionflow. Requires the PaperCanvas engine installed separately: Python 3.11+ and the papercanvas CLI (not yet on PyPI — install it from this repository, put it on PATH or set papercanvasBin); the plugin is a thin adapter and ships no engine.

Native generation-time Mixture-of-Agents: every turn, reference models run the same session context in parallel as pre-run drafts and one aggregator executes with full tooling; config-as-model recipes, F mirror / R trimmed views, enforced subagent gating (dual-shape session indexing), derived per-recipe vision (vision refs relay image reads to text-only aggregators), tiered cadence with separate steering and patrol rosters plus frozen reuse between beats, degeneration guard dropping degenerate reference output, anonymized model face (failure notices carry no provider identity), and cache-friendly guidance placement (the rehearsal record is pinned where it was produced instead of appended to every request, so the cached prefix covers it and each step pays only for what was added since - on by default across every cadence).

Three literature-research skills packaged as one DSH plugin: academic-web-research (lightweight proxy fetch), academic-literature-research (Scholar/IEEE/CNKI/Wanfang/Sci-Hub pipeline), off-campus-literature (campus WebVPN/CARSI access). Installing drops the three SKILL.md folders into ~/.dsh/skills/, so the agent can invoke them by name after a restart. The bundled web-research skill assumes a local HTTP proxy at 127.0.0.1:7897; edit it if your setup differs.
