dsh-artifacts

Claude-Artifacts-style rendering for DeepSeek Harness. Turn raw agent output — Markdown + JSON — into beautiful, shareable, self-contained HTML documents, cards, dashboards, and galleries. One command. Zero runtime dependencies.

English | 中文

Your agent produces Markdown and JSON all day. Most of it ends up as unstyled terminal text that nobody shares. dsh-artifacts fixes that: the same content, rendered as a polished, dependency-free HTML artifact you can open from disk, attach to an email, or drop on any static host.

Live demo: https://zoahdev.github.io/dsh-artifacts/

Published on npm: dsh-artifacts

Why

• No design skills required. Pick a template + theme, get a finished page.
• Self-contained. All CSS is inlined — no external fonts, frameworks, or tracking. The output works offline and forever.
• Works two ways. A CLI for you, and an artifact_render tool for the agent itself.
• Zero runtime dependencies. Node ≥ 18 only; nothing to audit.

Quick start

# As a standalone CLI
pnpm add -g dsh-artifacts
# or: npm install -g dsh-artifacts
dsh-artifacts notes.md --title "Release notes" --theme dark --out notes.html
dsh-artifacts notes.md --serve 8080          # live preview

# Or via npx without installing
npx dsh-artifacts notes.md --theme paper --out notes.html

Install as a DeepSeek Harness plugin:

dsh plugin --profile web add dsh-artifacts
# or, using the upstream CLI directly:
pnpm dlx @deepseek-ai/dsh plugin --profile web add dsh-artifacts

Then the agent can call artifact_render from chat to write a styled report to disk and hand you back the path.

Templates

All four templates, rendered from the same demo inputs in this repo:

Themes

Examples

Document from Markdown:

dsh-artifacts demo/sample.md \
  --title "Release notes" \
  --subtitle "dsh-artifacts v0.1.0" \
  --theme dark \
  --out release-notes.html

Dashboard from JSON:

dsh-artifacts --data demo/metrics.json \
  --title "Agent fleet dashboard" \
  --template dashboard \
  --theme brand \
  --out dashboard.html

{
  "metrics": [
    { "label": "Sessions", "value": 128, "delta": "+12" },
    { "label": "CI", "value": true }
  ],
  "bars": [
    { "label": "Monday", "value": 8 },
    { "label": "Tuesday", "value": 14 }
  ],
  "columns": ["tool", "calls", "median_ms"],
  "rows": [["read_file", "412", "38"]]
}

Gallery from JSON:

dsh-artifacts --data gallery.json --template gallery --theme light

{ "items": [ { "title": "A", "image": "https://…/a.png", "tag": "new" } ] }

Vault export (Obsidian / VS Code / any folder of Markdown)

dsh-artifacts is not DSH-only. Point it at any folder of .md notes — an Obsidian vault, a VS Code notes directory, blog drafts, or docs — and it renders one self-contained HTML page per note plus a linked index.html:

dsh-artifacts vault ./my-notes --theme paper --out site
# site/index.html + site/<note>.html

The first # heading of each note becomes its title; the first meaningful line becomes the index excerpt. Ignored folders include node_modules, .git, .obsidian, and .trash. Use --no-recursive for the top level only.

In-harness tool

artifact_render accepts:

It returns { path, bytes, title, template, theme }.

Library use

import { renderArtifact } from 'dsh-artifacts'

const { html } = renderArtifact({
  title: 'Weekly report',
  markdown: '# Shipped',
  template: 'doc',
  theme: 'dark',
})

What CI actually proves

build → unit tests → pack → install the real tarball into a fresh project → load the packed bundle → register artifact_renderviaapply() → execute the real handler → assert a real HTML file + rendered output.

In a second step, CI installs the packed plugin into a fresh DSH_HOME profile, verifies it appears in --dump-config, boots the real dsh web server, and asserts HTTP 200.

The smoke test also installs against an old @deepseek-ai/dsh-tools RC and asserts the runtime guard rejects it loudly (instead of failing later).

Tested with

• @deepseek-ai/dsh-tools ^0.1.0-rc.6
• @deepseek-ai/cordis ^4.0.1
• Node ≥ 18 (CI runs Node 22)

The peer range is declared as a caret range (not a hard pin). At runtime the plugin refuses to load if the resolved dsh-tools version is outside that tested range.

Troubleshooting

Installing the plugin fails with ERESOLVE / a peer-dependency conflict against an older @deepseek-ai/dsh-tools RC.

The plugin is tested against ^0.1.0-rc.6. If your harness is on an older RC (for example 0.1.0-rc.5), upgrade the host first, then install the plugin:

pnpm dlx @deepseek-ai/dsh --version          # check your version
pnpm dlx @deepseek-ai/dsh plugin --profile web add dsh-artifacts

If a package manager still resolves an old RC into the plugin's peer slot, the plugin throws on load:

dsh-artifacts: resolved @deepseek-ai/dsh-tools 0.1.0-rc.5, but this plugin is
tested with ^0.1.0-rc.6. Upgrade DeepSeek Harness to 0.1.0-rc.6 or later, then
reinstall.

Upgrade the host environment to 0.1.0-rc.6 (or later) and reinstall; do not edit the plugin's peer range to "fix" the conflict, because older RCs are not verified.

Honest limits

• The Markdown renderer covers the common subset (headings, lists, quotes, code, tables, links, images). It is not a full CommonMark implementation.
• Dashboards are static HTML/CSS; there is no JavaScript runtime, streaming, or live data binding (the --serve mode re-renders on refresh).
• This is a community plugin, not an official DeepSeek product. It is not a security boundary and has not been security-audited.

Publishing checklist

• pnpm install --frozen-lockfile
• pnpm typecheck
• pnpm build
• pnpm test
• pnpm pack
• packaged plugin loads and artifact_render invokes successfully
• bilingual README

Releases

Push a v* tag and GitHub Actions publishes the package to npm automatically:

npm version patch && git push --tags

The NPM_TOKEN repository secret is a granular access token scoped to dsh-artifacts (read + write, 2FA bypass for automation).

中文

给 DeepSeek Harness 的「Claude Artifacts」式渲染。 把 Agent 产出的 Markdown + JSON，一键变成漂亮、可分享、自包含的 HTML 文档、卡片、仪表盘和 画廊。零运行时依赖。

你的 Agent 整天都在输出 Markdown 和 JSON，但大多数最后都只是没人愿意分享的 终端文本。dsh-artifacts 解决这个问题：同样的内容，渲染成干净、自包含的 HTML 产物，可以直接打开、发邮件或放到任意静态站点。

特点

• 无需设计能力 — 选模板 + 主题，直接得到成品页面。
• 完全自包含 — CSS 全部内联，不依赖外部字体、框架或追踪脚本，离线永久可用。
• 两种用法 — 命令行给你用，artifact_render 工具给 Agent 用。
• 零运行时依赖 — 只需 Node ≥ 18。

快速开始

pnpm add -g dsh-artifacts
dsh-artifacts notes.md --title "发布说明" --theme dark --out notes.html
dsh-artifacts notes.md --serve 8080        # 实时预览

作为 DeepSeek Harness 插件安装：

dsh plugin --profile web add dsh-artifacts
pnpm dlx @deepseek-ai/dsh plugin --profile web add dsh-artifacts

模板

主题

Vault 导出（Obsidian / VS Code / 任意 Markdown 文件夹）

不只用于 DSH。指向任意 .md 笔记目录（Obsidian 库、VS Code 笔记、博客草稿、文档）， 每条笔记生成一个自包含 HTML 页，外加带链接的 index.html：

dsh-artifacts vault ./my-notes --theme paper --out site

已验证

• @deepseek-ai/dsh-tools ^0.1.0-rc.6
• @deepseek-ai/cordis ^4.0.1
• Node ≥ 18（CI 使用 Node 22）

排障

安装插件时因旧版 @deepseek-ai/dsh-tools RC 出现 ERESOLVE / peer 冲突。

先把宿主环境升级到 0.1.0-rc.6 或更新版本，再安装插件；不要靠放宽 peer 范围 来「修复」冲突，因为更旧的 RC 未经验证。插件在加载时若解析到不兼容版本会直接 报错并给出升级提示。

诚实边界

• Markdown 渲染覆盖常用子集（标题、列表、引用、代码、表格、链接、图片），并非 完整 CommonMark。
• 仪表盘是静态 HTML/CSS，没有 JS 运行时、流式或实时数据绑定。
• 这是社区插件，不是 DeepSeek 官方产品，未经安全审计。
