generative-ui
Design system and templates for Claude's built-in generative UI — the show_widget tool that renders interactive HTML/SVG widgets inline in claude.ai conversations. Use this skill whenever the user wants visual or interactive output rather than plain text or markdown: charts and dashboards, diagrams, flowcharts and architecture drawings, mockups, comparison grids, illustrations, interactive explainers ("explain how X works" with a visual), or tools with sliders, toggles, and live-updating displays — including financial data shown visually and requests phrased as "show me", "visualize", "draw", or "chart this".

- Design system and templates for Claude's built-in generative UI — the show_widget tool that renders interactive HTML/SVG widgets inline in claude.ai conversations. Use this skill whenever the user wants visual or interactive output rather than plain text or markdown: charts and dashboards, diagrams, flowcharts and architecture drawings, mockups, comparison grids, illustrations, interactive explainers ("explain how X works" with a visual), or tools with sliders, toggles, and live-updating displays — including financial data shown visually and requests phrased as "show me", "visualize", "draw", or "chart this".
# Generative UI Skill
This skill contains the complete design system for Claude's built-in `show_widget` tool — the generative UI feature that renders interactive HTML/SVG widgets inline in claude.ai conversations. The guidelines below are the actual Anthropic "Imagine — Visual Creation Suite" design rules, extracted so you can produce high-quality widgets directly without needing the `read_me` setup call.
**How it works**: On claude.ai, Claude has access to the `show_widget` tool which renders raw HTML/SVG fragments inline in the conversation. This skill provides the design system, templates, and patterns to use it well.
---
## Step 1: Pick the Right Visual Type
Route on the **verb**, not the noun. Same subject, different visual depending on what was asked:
| User says | Type | Format |
|---|---|---|
| "how does X work" | Illustrative diagram | SVG |
| "X architecture" | Structural diagram | SVG |
| "what are the steps" | Flowchart | SVG |
| "explain compound interest" | Interactive explainer | HTML |
| "compare these options" | Comparison grid | HTML |
| "show revenue chart" | Chart.js chart | HTML |
| "create a contact card" | Data record | HTML |
| "draw a sunset" | Art/illustration | SVG |
---
## Step 2: Build the Widget
### Structure (strict order)
```
<style> → HTML content → <script>
```
Output streams token-by-token. Styles must exist before the elements they target, and scripts must run after the DOM is ready.
### Philosophy
- **Seamless**: Users shouldn't notice where the host UI ends and your widget begins
- **Flat**: No gradients, mesh backgrounds, noise textures, or decorative effects. Clean flat surfaces
- **Compact**: Show the essential inline. Explain the rest in text
- **No stock "AI design" defaults**: skip cream or off-white panels, italic accent words in headings, numbered "01 / 02 / 03" section labels, monospace labels outside code, and pill-shaped buttons — they read as generic and clash with the host UI
- **Text goes in your response, visuals go in the tool** — write explanatory text, descriptions, and summaries as normal response text outside the tool call; the widget holds only the visual element
### Core Rules
- No `<!-- comments -->` or `/* comments */` (waste tokens, break streaming)
- No font-size below 11px
- No emoji — use CSS shapes or SVG paths
- No gradients, drop shadows, blur, glow, or neon effects
- No dark/colored backgrounds on outer containers (transparent only — host provides the bg)
- **Typography**: two weights only: 400 regular, 500 medium. Never use 600 or 700. Headings: h1=22px, h2=18px, h3=16px — all font-weight 500. Body text=16px, weight 400, line-height 1.7
- **Sentence case** always. Never Title Case, never ALL CAPS
- No mid-sentence bolding — entity names go in `code style` not **bold**
- No `<!DOCTYPE>`, `<html>`, `<head>`, or `<body>` — just content fragments
- No `position: fixed` — use normal-flow layouts
- No tabs, carousels, or `display: none` sections during streaming
- No nested scrolling — auto-fit height
- Corners: `border-radius: var(--border-radius-lg)` for cards, `var(--border-radius-md)` for elements
- No rounded corners on single-sided borders (border-left, border-top)
- **Round every displayed number** — use `Math.round()`, `.toFixed(n)`, or `Intl.NumberFormat`
### CDN Allowlist (CSP-enforced)
External resources may ONLY load from:
- `cdnjs.cloudflare.com`
- `cdn.jsdelivr.net`
- `unpkg.com`
- `esm.sh`
All other origins are blocked — the request silently fails.
### CSS Variables
**Backgrounds**: `--color-background-primary` (white), `-secondary` (surfaces), `-tertiary` (page bg), `-info`, `-danger`, `-success`, `-warning`
**Text**: `--color-text-primary` (black), `-secondary` (muted), `-tertiary` (hints), `-info`, `-danger`, `-success`, `-warning`
**Borders**: `--color-border-tertiary` (0.15α, default), `-secondary` (0.3α, hover), `-primary` (0.4α), semantic `-info/-danger/-success/-warning`
**Typography**: `--font-sans`, `--font-serif`, `--font-mono`
**Layout**: `--border-radius-md` (8px), `--border-radius-lg` (12px), `--border-radius-xl` (16px)
All auto-adapt to light/dark mode.
**Dark mode is mandatory** — every color must work in both modes:
- In HTML: always use CSS variables for text. Never hardcode colors like `color: #333`
- In SVG: use pre-built color classes (`c-blue`, `c-teal`, etc.) — they handle light/dark automatically
- Mental test: if the background were near-black, would every text element still be readable?
### `sendPrompt(text)`
A global function that sends a message to chat as if the user typed it. Use it when the user's next step benefits from Claude thinking. Handle filtering, sorting, toggling, and calculations in JS instead.

## Step 3: Render with `show_widget`
The `show_widget` tool is built into claude.ai — no activation needed. Pass your widget code directly:
```json
{
"title": "snake_case_widget_name",
"widget_code": "<style>...</style>\n<div>...</div>\n<script>...</script>"
}
```
| Parameter | Type | Required | Description |
|---|---|---|---|
| `title` | string | Yes | Snake_case identifier for the widget |
| `widget_code` | string | Yes | HTML or SVG code. For SVG: start with `<svg>`. For HTML: content fragment |
For SVG output: start `widget_code` with `<svg` — it will be auto-detected and wrapped appropriately.

## Step 4: Chart.js Template
For charts, use `onload` callback pattern to handle script load ordering:
```html
<div style="display: grid; grid-template-columns: repeat(auto-fit, minmax(140px, 1fr)); gap: 12px;">
<div style="background: var(--color-background-secondary); border-radius: var(--border-radius-md); padding: 1rem;">
<div style="font-size: 13px; color: var(--color-text-secondary);">Label</div>
<div style="font-size: 24px; font-weight: 500;" id="stat1">—</div>
</div>
</div>
<div style="position: relative; width: 100%; height: 300px; margin-top: 1rem;">
<canvas id="myChart"></canvas>
</div>
<div style="display: flex; align-items: center; gap: 12px; margin-top: 1rem;">
<label style="font-size: 14px; color: var(--color-text-secondary);">Parameter</label>
<input type="range" min="0" max="100" value="50" id="param" step="1" style="flex: 1;" />
<span style="font-size: 14px; font-weight: 500; min-width: 32px;" id="param-out">50</span>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/4.5.1/chart.umd.js" onload="initChart()"></script>
<script>
function initChart() {
const slider = document.getElementById('param');
const out = document.getElementById('param-out');
let chart = null;
function update() {
const val = parseFloat(slider.value);
out.textContent = val;
document.getElementById('stat1').textContent = val.toFixed(1);
const labels = [], data = [];
for (let x = 0; x <= 100; x++) {
labels.push(x);
data.push(x * val / 100);
}
if (chart) chart.destroy();
chart = new Chart(document.getElementById('myChart'), {
type: 'line',
data: { labels, datasets: [{ data, borderColor: '#7F77DD', borderWidth: 2, pointRadius: 0, fill: false }] },
options: {
responsive: true,
maintainAspectRatio: false,
plugins: { legend: { display: false } },
scales: { x: { grid: { display: false } } }
}
});
}
slider.addEventListener('input', update);
update();
}
if (window.Chart) initChart();
</script>
```
**Chart.js rules:**
- Canvas cannot resolve CSS variables — use hardcoded hex
- Set height ONLY on the wrapper div, never on canvas itself
- Always `responsive: true, maintainAspectRatio: false`
- Always disable default legend, build custom HTML legends
- Number formatting: `-$5M` not `$-5M` (negative sign before currency symbol)
- Use `onload="initChart()"` on CDN script tag + `if (window.Chart) initChart();` as fallback

## Step 5: SVG Diagram Template
For flowcharts and diagrams, use SVG with pre-built classes:
```svg
<svg width="100%" viewBox="0 0 680 H">
<defs>
<marker id="arrow" viewBox="0 0 10 10" refX="8" refY="5" markerWidth="6" markerHeight="6" orient="auto-start-reverse">
<path d="M2 1L8 5L2 9" fill="none" stroke="context-stroke" stroke-width="1.5" stroke-linecap="round" stroke-linejoin="round"/>
</marker>
</defs>
<!-- Single-line node (44px tall) -->
<g class="node c-blue" onclick="sendPrompt('Tell me more about this')">
<rect x="250" y="40" width="180" height="44" rx="8" stroke-width="0.5"/>
<text class="th" x="340" y="62" text-anchor="middle" dominant-baseline="central">Step one</text>
</g>
<!-- Connector arrow -->
<line x1="340" y1="84" x2="340" y2="120" class="arr" marker-end="url(#arrow)"/>
<!-- Two-line node (56px tall) -->
<g class="node c-teal" onclick="sendPrompt('Explain this step')">
<rect x="230" y="120" width="220" height="56" rx="8" stroke-width="0.5"/>
<text class="th" x="340" y="140" text-anchor="middle" dominant-baseline="central">Step two</text>
<text class="ts" x="340" y="158" text-anchor="middle" dominant-baseline="central">Processes the input</text>
</g>
</svg>
```
**SVG rules:**
- ViewBox always 680px wide (`viewBox="0 0 680 H"`). Set H to fit content + 40px padding
- Safe area: x=40 to x=640, y=40 to y=(H-40)
- Pre-built classes: `t` (14px), `ts` (12px secondary), `th` (14px medium 500), `box`, `node`, `arr`, `c-{color}`
- Every `<text>` element must carry a class (`t`, `ts`, or `th`)
- Use `dominant-baseline="central"` for vertical text centering in boxes
- Connector paths need `fill="none"` (SVG defaults to `fill: black`)
- Stroke width: 0.5px for borders and edges
- Make all nodes clickable: `onclick="sendPrompt('...')"`

## Step 6: Interactive Explainer Template
For interactive explainers (sliders, live calculations, inline SVG):
```html
<div style="display: flex; align-items: center; gap: 12px; margin: 0 0 1.5rem;">
<label style="font-size: 14px; color: var(--color-text-secondary);">Years</label>
<input type="range" min="1" max="40" value="20" id="years" style="flex: 1;" />
<span style="font-size: 14px; font-weight: 500; min-width: 24px;" id="years-out">20</span>
</div>
<div style="display: flex; align-items: baseline; gap: 8px; margin: 0 0 1.5rem;">
<span style="font-size: 14px; color: var(--color-text-secondary);">$1,000 →</span>
<span style="font-size: 24px; font-weight: 500;" id="result">$3,870</span>
</div>
<div style="margin: 2rem 0; position: relative; height: 240px;">
<canvas id="chart"></canvas>
</div>
