Plugins

Read-only CAD tools that inspect, extract and export DWG/DXF drawings, including SVG and PNG previews and DXF conversion.

Registers /wrapped, which reads the session's own stats and renders a shareable dark SVG summary card — tool vs. thinking time, decode speed, and a tool/thinking-ratio verdict.

Publishes a project plan the agent writes: ordered steps in a panel docked to the right of the frame, and the framework graph as an auto-laid-out diagram in its own centre tab, downloadable as SVG or PNG. Charts are rebuilt from the session log, so they survive restart and resume.

Visual HTML/SVG Studio：一个 DeepSeek Harness 网页插件，用于在浏览器中打开、实时预览、检查并批注工作区里的 HTML/SVG 文件，批注会直接送回当前 Agent 会话由 AI 修改源码。

Client-only dsh plugin that renders Mermaid fenced code blocks as SVG diagrams in the web UI

`describe_image` tool: a vision bridge that sends images to mimo-v2.5 through the opencode Zen API (credential `OPENCODE_GO_API_KEY`, free route first with paid fallback) and returns text descriptions for text-only models, with native passthrough and ImageMagick transcoding of SVG/TIFF/HEIC formats.

Reminds you to stop working at several times a day (default 12:10 and 18:00, up to 12 editable points): at each time the host raises the DSH window to the front — restoring it if minimized and taking the foreground even from another application — and a full-screen animated alert appears with a five-minute snooze and a dismiss button. The alert can show your own image (SVG, PNG, GIF, JPEG or WebP, with GIF animation) instead of the default clock icon; times, image, mute and the auto-focus switch persist in localStorage.

Test configured DSH models with connectivity, behavioral fingerprint and a local 18-item weighted intelligence battery scoring 0-100 with a tier and per-question evidence, plus animated or custom SVG probes, quick SVG limits, concurrency controls, and latency and token metrics.

Sidebar and conversation top-bar menu editor for DSH web: reorder, group, hide and re-icon entries (drag and drop, group flyouts, custom SVG or uploaded icons), reserves a configurable minimum height for the workspace tree, and exposes window.__dshSidebarManager for agents.

Let agents read and control the web page open in the right Sidebar Browser tab — read text, run JS, click (HTML and SVG), type, scroll, screenshot, with a per-command token bridge behind the Harness connection fence. Full control and screenshots need the DSH Desktop app; in a regular browser (Web) only same-origin pages can be read or scripted.

A local mirrored A/B benchmark for context compression, not another compressor. It runs one fixed read-only scenario twice with the same model and temperature — compression off, then on — and reports input tokens, turns, tool-call success, fact coverage, answer similarity and a per-line diff, with JSON, a self-contained SVG and raw warnings. 18 node --test tests, zero dependencies. The first measured run: 63,029 → 6,927 locally estimated input tokens (−89.0%), 3 → 3 turns, facts 3/3 → 3/3, answer similarity 1.00 on one sample.

Left sidebar poster workshop with a live deepseek.com/harness fluid-shader background: edit an eyebrow, a two-line headline, subtitle, body copy and footer, switch between four ratios and four palettes, then export a PNG or a self-contained SVG. The official Montserrat font is embedded, so no network is needed.

Renders SVG code fences in chat as theme-aware inline figures with source, copy, download and zoom.

VS Code-style multi-repository Git panel in the DSH right sidebar: repository and branch pickers, staged/unstaged changes with inline diffs and per-file actions, commit, stash/tag/worktree menus, a connected SVG commit graph with branch multi-select, and fetch/pull/push/sync.

Channel test page for any configured provider/model: multi-round prompt-cache hit rate, streaming TTFT and tok/s, and a pelican SVG test.

GIS/CAD analysis toolkit for dsh: read DXF, convert DWG to DXF, query layers/entities, export styled analysis maps (SVG/PNG/JPG/PDF, plus PSD on Windows x64), and run GIS summary/buffer/overlay on SHP/GeoJSON/KML — pure-JS parsing, no GDAL.

Codebase knowledge graphs for DeepSeek Harness: seven graphify_* Agent tools, a /graphify command, and a Graphify page build and query a project graph locally with AST parsing (no API key), plus path/explain/god-node lookups and wiki/HTML/SVG/GraphML/Obsidian exports. Requires the graphify CLI (graphifyy); only full document/PDF/image extraction needs an LLM key.

Assign per-session duotone SVG icons and colors from the sidebar menu or a model tool, with browser-local persistence and cross-tab updates.

DSH 插件：在右侧栏预览里对科研配图、SVG、PDF、HTML 直接圈画批注，标注写进侧车文件并可一键交给智能体改图源

Syntax-highlighted code for reports via one highlight_code tool: 68 languages, 15 themes, 11 output formats (inline HTML, Word-ready SVG/PNG, LaTeX), incl. the classic SyntaxHighlighter themes. PNG output needs Python 3 with Pillow; other formats need no external runtime.

Export diagram-design HTML diagrams to SVG/PNG, extract draw.io/Mermaid/Excalidraw structure, validate output, and browse 45 diagram types. Built on cathrynlavery/diagram-design (MIT); needs python3, and PNG export additionally needs Playwright.

Whale-girl desktop pet for the DSH Web UI, drawn with hand-written SVG + CSS (no image or audio assets, zero runtime dependencies): swims while a turn runs, blows labeled bubbles on tool calls, taps the glass with an amber pulse when an approval is waiting, jumps with a turn duration/tool-count report on success and droops on failure, naps after dark or when idle. Click to poke, double-click to pet (affinity hearts), drag with remembered position, right-click menu (feed / mute / reset / hide), hover card with level, title, XP bar and per-turn stats. A `whale_say` tool lets the agent make her speak or act as a lightweight visible notification. Read-only over sessions and workspace; only ~/.dsh/whale-girl/state.json is written.

Renders an Agent Teams swimlane canvas above the composer: lead centred with members below, tasks laid out in lanes by longest dependency path, and four SVG connector families drawn as dashed paths (task dependency as a cubic bezier from the upstream card edge to the downstream card edge, lead bus, peer bus, member-to-task tether). Cards are absolutely positioned DOM, connectors are one SVG layer sharing the same geometry constants. Layout constants and path algorithms are ported from cc-haha. Reads the live per-session agentTeam projection (roster, shared tasks, dependency edges, running state) and falls back to the session todo list when the session has no team; team messages are not part of the projection yet, so the communication panel shows an empty state. Body colours come from host theme tokens; the eight member identity colours are the deliberate exception — fixed hues mixed with the theme accent via color-mix, declared as CSS variables because the same values feed an SVG stroke attribute that rejects colour functions. Ships zh/en dictionaries with identical keys.

Generates release material from what a local repository can actually support: a hero image, a feature grid and bilingual copy rendered as SVG and HTML from `README.md`, `package.json` and optional screenshots. Facts are quoted from those files — name, version, license, summary, features, install snippet — and a field that is missing is left unrendered rather than filled with placeholder text. Every feature carries a source citation such as `README.md#L42`, and a claim the repository cannot substantiate is linted out before anything is written, with the reasoning left in `lint-report.json`. `manifest.json` records a sha256 for each input and output, and `--now` or `SOURCE_DATE_EPOCH` makes a run byte-identical. Also ships a GUI panel that regenerates from inside a session.
