dsh-diagram
将 DeepSeek Harness 中的文章转换为可编辑的 Excalidraw 画布
插件会安装到这里；不确定时保持 web。
npx -y @deepseek-ai/dsh plugin --profile web add dsh-diagram@0.5.0Diagram 以 dsh-diagram 发布，当前版本为 0.5.0。Plugin Hub 会校验它的 manifest，并保存精确安装来源，便于复现安装结果。
English | 简体中文
Your DSH session already understands the article. Turn that understanding into an Excalidraw canvas you can keep editing.
The Agent creates the first structure; you refine it in DSH, autosave it, and export it. The result stays editable instead of becoming disposable Mermaid output.
From a DSH article session to an editable, saved Excalidraw canvas
Install it in one command, then type / and pick canvas-diagram in any DSH session:
npx -y @deepseek-ai/dsh@0.1.5-rc.1 plugin --profile web add dsh-diagram@latest
Useful for your DSH toolbox? Star the repo so you can find it when the next long article needs a diagram.
Full requirements and verification: Quick install.
.excalidraw, SVG, or PNG.Requirements:
0.1.5-rc.1 (latest); also verified on 0.1.5-rc.2 and 0.1.2-rc.1. DSH 0.1.1-rc.2 and older need dsh-diagram 0.4.0^22.19.0 or >=24.0.0>=10 on PATH (the DSH plugin command delegates package management to pnpm)127.0.0.1DeepSeek Harness does not install a global dsh command by default; the official way to launch it is through npx. The commands below work on any machine that meets the requirements:
npx -y @deepseek-ai/dsh@0.1.5-rc.1 plugin --profile web add dsh-diagram@latest
npx -y @deepseek-ai/dsh@0.1.5-rc.1 --profile web --dump-config
npx -y @deepseek-ai/dsh@0.1.5-rc.1 web
The config dump should contain this block:
# == dsh-diagram
- id: diagram
name: dsh-diagram
If DSH Web was already running, restart it after adding or updating the plugin. Then open an existing session and look for the Canvas tab.
Run the same commands from a DeepSeek Harness checkout that matches a supported release, using pnpm dsh as the prefix:
pnpm dsh plugin --profile web add dsh-diagram@latest
pnpm dsh --profile web --dump-config
pnpm dsh web
dsh is on your PATHIf you installed the CLI globally or created a shell alias, the short form works the same way:
dsh plugin --profile web add dsh-diagram@latest
dsh --profile web --dump-config
dsh web
Later sections use this short dsh form; substitute the npx -y @deepseek-ai/dsh@0.1.5-rc.1 or pnpm dsh prefix that matches how you run DSH.
Open a DSH session that already contains the article, or let the Agent read it with DSH's existing file or Web tools.
Type / in the composer and pick canvas-diagram — the plugin registers this skill so you never have to remember a tool name. Plain requests such as "把这篇文章画成架构图" route through the same skill automatically. An explicit prompt also works:
Create one clear diagram for this article. Choose the most suitable diagram type, call diagram_create, and keep the title and node labels concise.
For the optional editorial hand-drawn treatment, say so explicitly:
Turn this article into an editable sketchnote diagram. Use semantic icons only for the key concepts.
After the tool finishes, select Canvas at the top of the conversation.
Edit the diagram directly. Saved means the Host has completed a durable write.
Export the result, or ask the Agent to call diagram_read before continuing from your manual changes.
The plugin supports report boards, flowcharts, architecture diagrams, timelines, hierarchies, comparisons, and relationship diagrams. Visual style is independent of diagram type: omitted/clean preserves the original rendering, while sketchnote uses warm paper, near-black ink, low-saturation marker fills, handwritten text, and a controlled set of native Excalidraw icons. Evidence-heavy reports use deterministic full-width context/outcome bands, aligned main columns, semantic colors, and converter-measured native text placement. Report and grouped-architecture connectors select stable node-boundary ports and orthogonal corridors while avoiding unrelated nodes, group headings, and independent routed edges.
| Surface | Behavior |
|---|---|
diagram_create | Creates a diagram for the current Agent Session from a compact semantic specification. visualStyle: "sketchnote" selects the optional hand-drawn compiler; controlled icon values compile to editable native primitives rather than images. |
diagram_read | Reads a bounded summary of the current editable scene into the conversation transcript. |
canvas-diagram skill | Built-in bilingual routing entry: selectable from the composer's / menu and matched by generic diagram requests, so the Agent reaches diagram_create without exact tool-name prompts. |
| Inline chat preview | After diagram_create, a preview card appears in the conversation flow and always renders the diagram's current content — including later canvas edits — as a static SVG. |
| Canvas tab | Opens the Excalidraw editor only when selected, keeping it out of the normal chat startup path. |
| Diagram list | Switches between diagrams; collapses on desktop and becomes a selector on narrow screens. |
| Autosave | Debounced durable writes with revision conflict protection and tab-local pending-draft recovery. |
| Export | Downloads .excalidraw, SVG, or PNG files. |
The plugin does not fetch articles and does not inject UI into arbitrary websites. Article acquisition stays with the DSH conversation, file tools, or Web tools.
| Item | Supported in 0.5.0 |
|---|---|
| DeepSeek Harness | 0.1.5-rc.1, 0.1.5-rc.2, 0.1.2-rc.1 (older DSH: use dsh-diagram@0.4.0) |
| Profile | web |
| Web bind address | 127.0.0.1 only |
| Node.js | ^22.19.0 or >=24.0.0 |
| Editor | Excalidraw 0.18.1 |
| Storage | Plugin-owned DSH storage-domain sidecar |
| Install artifact | Prebuilt npm package or GitHub Release tarball with SHA-256 checksum |
The npm package has no install lifecycle scripts. Installation adds a bundle to the selected DSH profile; it does not compile code or modify the DeepSeek Harness source tree.
dsh plugin --profile web update dsh-diagram --latest
Restart DSH Web after the update.
The release page publishes the same prebuilt tarball with a SHA-256 checksum:
dsh plugin --profile web add \
https://github.com/hanzhangzzz/dsh-diagram/releases/download/v0.5.0/dsh-diagram-0.5.0.tgz
See v0.5.0 for the checksum and release notes.
dsh plugin --profile web remove dsh-diagram
Removing the bundle does not delete saved diagram sidecar data. Reinstalling the plugin can make that data available again to the same Session identity.
{createdAt, cwd} lifecycle fingerprint. A reused Session id cannot read older data.cordis.patch.yml.0.0.0.0; this release does not expose the canvas RPC to a LAN.Confirm that you installed the plugin into the web profile, that --dump-config contains the dsh-diagram block shown above, and that DSH Web was restarted after installation.
The model chooses freely among all tools and workspace skills in the session. The plugin registers its own canvas-diagram skill so generic diagram requests normally route to the canvas; if a workspace skill with a stronger matching description still wins, pick canvas-diagram from the / menu or mention the Canvas explicitly — for example, "call diagram_create so I can edit the result in the Canvas tab".
Manual edits are not silently injected into model context. Ask the Agent to call diagram_read; its result is then recorded in the normal conversation transcript.
No. First let DSH obtain the content through the conversation, a file tool, or a Web tool. Then ask for a diagram.
0.0.0.0?The canvas RPC is not designed for LAN exposure in this release. The plugin fails closed unless DSH Web is physically bound to 127.0.0.1.
The editor keeps the local draft. Export it before choosing Reload server version if you need to preserve both versions.
Under the strict content security policy, Excalidraw may fall back from glyph subsetting to embedding the full self-hosted font. The exported SVG remains self-contained; the plugin does not enable unsafe-eval to suppress the warning.
git clone https://github.com/hanzhangzzz/dsh-diagram.git
cd dsh-diagram
pnpm install --frozen-lockfile
pnpm run bundle
pnpm pack
Install the generated tarball from a DeepSeek Harness checkout:
cd /path/to/deepseek-harness
pnpm dsh plugin --profile web add /absolute/path/to/dsh-diagram-VERSION.tgz
pnpm dsh --profile web --dump-config
pnpm dsh web
Developer checks:
pnpm run typecheck
pnpm run test
pnpm run bundle
pnpm pack --json
pnpm run smoke:dsh-install
Every installable development commit must use a new prerelease version; never repack changed code under an existing version. Before a public release, pack once and exercise the same DSH profile update path from the previous public version to that exact tarball:
pnpm run smoke:dsh-install -- \
--tarball /absolute/path/to/dsh-diagram-VERSION.tgz \
--upgrade-from PREVIOUS_PUBLIC_VERSION
This verifies the client-side update mechanics and both pre/post-update Web
boots without publishing the candidate. Registry discovery through @latest
is verified separately after the version is publicly released.
