🎨 dsh-genui
Give the model's answers a face — the text is still there, and an interactive UI is already live.
🔌 Ecosystem: the repo carries the #dsh · #dsh-plugin topics — welcome to be listed by @dsh-plugin.
dsh-genui turns a model reply into a safe, interactive DSH surface. Ask “how are this month’s orders doing?” and the answer can include a sortable data panel, a native video, a draggable plot, a local quiz, or a persistent session panel — without replacing the surrounding text.

Three real outputs inside a DSH reply
1. A monitoring panel is an answer, not a separate dashboard
Real dsh-genui monitoring panel rendered inside a DSH conversation
Real output: refresh/reset controls, time-range selection, statistics, charts, and a service table live inside the assistant reply.
2. A function plot redraws locally as its parameters change
Real dsh-genui function plot with draggable parameter sliders
Real output: `plot` renders curves while sliders, reset, and animation controls update the graph locally.
3. Layout primitives compose into structured work surfaces
Real dsh-genui layout and card component composition
Real output: typography, grid, card, and row/column primitives combine into a hierarchy the model can describe declaratively.
⚠️ Read this first: dual-channel rendering (no host source patch required)
The plugin ships two rendering channels and picks one automatically after the host activates its browser module:
- Registry channel: when the host exposes the
fence-registry extension point (newer dsh builds), fences register through the host's streaming render pipeline and behave seamlessly with the host;
- DOM channel: when the host lacks that extension point (including stock DSH and older builds), the plugin observes the session DOM and mounts its own render tree. Since 0.7.2 it supports streaming rendering: components appear as the model writes them — the first finished component shows up immediately, no need to wait for the whole reply. Since 0.8.3 fence discovery is multi-surface: it matches the stock
md-code-block surface, the deepsuite-style .code-block / .code-block-small surfaces some host builds render instead, and — as a structural backstop — any element whose banner labels it dsh-ui and contains a <pre> body. If your dsh build renders fences with a different class name, they still render (and a one-time console warning tells you the host DOM drifted).
Whichever channel is active, components, interactions, panels, and persistence behave identically.
The repository ships both renderer channels, the host plugin, and the built browser bundle. The host still owns client activation and must provide the slots and sessions services. A downloaded client.js or a ModuleLoader cache entry proves only that bytes arrived — successful activation always prints [genui] client active; fence-channel=registry|dom. If that line is absent, fix package/profile identity or host activation first; DOM attributes such as data-streaming and data-chat-anchor-key are optional fallbacks, not installation prerequisites.
✨ Before vs. after
| Plain answer | With dsh-genui |
|---|
| "Revenue this month: ¥128,430, +12.4% MoM — watch the conversion rate." | One line of analysis + three stat cards (revenue / orders / conversion), a trend chart, and a progress bar rendered right beside it |
| Want to see more? Type another question. | The panel already has "Refresh" / "Switch view" buttons — click, and the model updates the data |
🚀 Quick start
Prerequisites — all required:
- dsh installed (any open-source build works — the plugin picks its rendering channel at startup, see "dual-channel rendering" above)
pnpm on your PATH: the dsh plugin command depends on it. If missing: corepack enable (or npm i -g pnpm), then open a new terminal and confirm pnpm -v prints a version
Install (one command, all dependencies included):
# Public GitHub install (works without an npm account)
dsh plugin --profile web add git+https://github.com/omdsh-dev/dsh-genui.git
⚠️ Don't use link: on a freshly cloned directory — link: does not install the plugin's dependencies (mermaid / three / react), so the renderer will break. Use the git URL form above; reserve link: for local development iteration (see below).
Verify the install in 60 seconds
After the command completes, restart dsh web and hard-refresh the browser. In a new session, say:
Use dsh-ui to draw a stats dashboard with a sortable service table.
You should see the reply turn into an in-place dashboard rather than a code block. For an unambiguous technical check, open the browser console: successful activation prints [genui] client active; fence-channel=registry|dom.
One-click script (recommended)
After cloning, just run it — the script checks the prerequisites above, performs the install, and prompts you to restart:
git clone https://github.com/omdsh-dev/dsh-genui.git
cd dsh-genui
./scripts/install.sh
Developer iteration (link mode)
cd dsh-genui
pnpm install
dsh plugin --profile web add link:$PWD
🧩 Capability map
| Surface | First thing to try | Observable behavior |
|---|
| Data | Ask for an order or service dashboard | stat, table, chart, and progress appear inside the reply; supported numeric table values sort numerically. |
| Media | Ask for an audio or video reference | Browser-reachable media plays inline, with poster/aspect-ratio and failure states. |
| Exploration | Ask for plot with a parameter | Dragging sliders redraws the curve locally and immediately. |
| Feedback | Ask for a short quiz | The UI grades and explains locally; only the next model step needs an action. |
| Workspace | Ask for /panel or panel: true | A persistent, resizable session dock is updated in place. |
The following is the detailed capability reference. Every behavior is constrained by the whitelisted dsh-ui specification; see SKILL.md for the JSON syntax.
-
Answer-as-UI: components are embedded in the reply and appear as they stream — no waiting for the whole message
-
30+ components: cards, tables, charts, forms, tabs, accordions, file trees, timelines, diffs…
-
Native media: audio and video play inline from browser-reachable http(s) or same-origin relative URLs, with user-controlled playback, video posters/aspect ratios, and visible failure states
-
ECharts integration: the echart node renders full ECharts charts with theme-aware colors, tooltips, and legends. Two modes: preset shorthand (preset: 'bar' | 'line' | 'area' | 'pie' | 'scatter' + data/series) for quick upgrade from the chart node, or full option (option field) for custom chart types, dataZoom, visualMap, and other advanced ECharts features. The echarts engine (~1 MB) is lazy-loaded on demand — the main bundle never carries it, and conversations without echart nodes never download it- Function plots: plot draws curves; parameter sliders redraw in real time, with optional auto-animation
-
Quiz: quiz grades on click with explanation and retry; with action, the answer is also sent back to the model (grading stays local and instant)
-
Local grading (submit): a multiple-choice set = one radio per question with group + answer (correct answer) + explanation, plus one submit button — after the user answers everything and clicks once, the score, per-question right/wrong, and explanations appear right in the UI with zero model round-trips; the quiz then locks, and "retake" resets locally (optional resetAction notifies the model). Questions without an answer fall back to an aggregated action (fields collects every input with an id)
-
State persistence: answers, submission locks, and input values are saved per "session + content fingerprint" — refresh or reopen restores everything; re-rendering identical content keeps user state; new content starts fresh; LRU cap of 200 blocks
-
Form semantics: input Enter / textarea Ctrl+Enter submits immediately (submit:true), no blur needed; fields with an are collected into the submit's
Component JSON syntax: SKILL.md (also copyable to ~/.dsh/skills/genui/ to boost the model).
📄 Example
The model outputs this fence (written for the browser — you don't need to read it):
{"title":"Order overview","items":[
{"type":"stat","label":"Total revenue","value":"¥128,430","delta":"+12.4%"},
{"type":"stat","label":"Orders","value":"1,024","delta":"-3.1%"}
]}
What you see: two stat cards.
ECharts example
{"title":"Q1 Revenue","items":[
{"type":"echart","title":"Monthly Revenue","preset":"bar","data":[
{"label":"Jan","value":98},
{"label":"Feb","value":112},
{"label":"Mar","value":128}
]}
]}
What you see: a themed bar chart with tooltips and axis labels — rendered by ECharts, lazy-loaded on demand.
🔧 How it works
The model writes the interface description as JSON inside a dsh-ui fence; the browser-side renderer (src/client) claims this language through the main repo's fence-registry interface and renders it. Components are whitelisted — the model can't smuggle in HTML/scripts; function expressions go through a standalone parser, never eval.
The core render package stays light (≈110 KB min / 28 KB gzip); the mermaid, three.js, and echarts engines are bundled separately as on-demand assets (loaded through the plugin's self-registered HTTP routes the first time they're used), so startup only downloads the rendering core.
❓ FAQ
- Rendering as a code block? First check the browser console for
[genui] client active; fence-channel=registry|dom. If absent, the client bundle was not activated even if its URL returns 200 — align the profile dependency, package.json.name, cordis.patch.yml, ModuleLoader id, and configured bundle name. If present, inspect the fence label/body; registry-less hosts automatically use the DOM channel.
- Chat UI goes blank when rendering a dsh-ui fence? Your dsh is too old — update dsh first, then reinstall the plugin.
dsh: pnpm not found on PATH? Install pnpm, then open a new terminal and retry (corepack enable or npm i -g pnpm).
- Stuck on git credentials / 404 during install? The repo is public (
omdsh-dev/dsh-genui) — the git URL above needs no login; a 404 for @omdsh-dev/dsh-genui means the npm package has not been published yet.
- Installed but scene3d/mermaid/echarts don't render? The engines (mermaid / three / echarts) are no longer inlined in client.js — they load on demand the first time they're used (
/plugins/@omdsh-dev/dsh-genui/assets/*.js, hosted by the plugin's own HTTP routes). First restart dsh web + hard refresh (Cmd+Shift+R); still broken, remove and reinstall (dsh plugin --profile web remove @omdsh-dev/dsh-genui, then add again). Hosts without the asset routes degrade to source/load-error hints — update dsh.
- Model not outputting fences? New sessions pick it up after a restart; or just say "output it with dsh-ui".
- No lib/ after cloning? Build it yourself:
pnpm install && pnpm run check.
🧑💻 Development
pnpm install
pnpm run check # type check + full tests + build
Real-device e2e
The real chain end to end: start a temporary dsh web → install the plugin → send a message in a browser so the model outputs a dsh-ui fence → assert the rendering → click an action button → assert the model responds (event-loop closure):
DEEPSEEK_API_KEY=sk-... node scripts/e2e.mjs # link-installs the current workspace
DEEPSEEK_API_KEY=sk-... node scripts/e2e.mjs --install git # friend path (git URL)
Prereqs: dsh/pnpm on PATH, DEEPSEEK_API_KEY, and the main repo's web build output (playwright resolves it from the main repo). On PASS it saves an e2e-final.png screenshot.
Visual e2e (no model key)
For style/component iterations, a visual smoke that needs no API key: boots a real dsh web with the plugin link-installed, injects the component gallery fence through the DOM channel, renders it in headless Chrome, screenshots the full page, and exercises local interactions (table sort, quiz judging, tree collapse, numeric alignment) with hard assertions:
npx tsx scripts/e2e-visual.mts # → .e2e-artifacts/gallery.png + interactions.png
npx tsx scripts/e2e-visual.mts --keep # keep the scratch DSH_HOME for debugging
Overridable: --port 3098, --out <dir>, DSH_BIN (defaults to the npm-mode ~/node_modules/.bin/dsh), PLAYWRIGHT_PATH (defaults to the global playwright-core).
🗺️ Roadmap (evaluated)
| Direction | Verdict | Rationale |
|---|
| Incremental patching (model sends diffs, not full specs) | Not doing | A fence costs 200–800 tokens; resending is nearly free; a patch protocol's teaching cost and error rate aren't worth it. Revisit if sub-second auto-refreshing panels ever appear |
| Action debounce/dedup | ✅ Done (300 ms trailing edge, per action name) | Rapid-click spam is real friction; one choke point |
| Cross-session state persistence (replay restores tabs/switches) | Not doing | Replay-reset is the more correct default (the model has already updated the UI with a new fence); state survives naturally during streaming |
| MCP adapter / standalone gallery page / i18n | Not doing | No cross-tool demand signal; gallery material is covered by gallery.ts + demo-prompts + README screenshots; only 6 built-in strings |
Unit tests and builds use the locked published dsh rc.8 packages. DSH_ROOT is only needed by source-level or end-to-end checks.
