What does the Generative Ui AI skill do?

Design system and guidelines for Claude's built-in generative UI — the show_widget tool that renders interactive HTML/SVG widgets inline in claude.ai conversations. This skill provides the complete Anthropic "Imagine" design system so Claude produces high-quality widgets without needing to call read_me first. Use this skill whenever the user asks to visualize data, create an interactive chart, build a dashboard, render a diagram, draw a flowchart, show a mockup, create an interactive explainer, or produce any visual content beyond plain text or markdown. Triggers include: "show me", "visual...

Why use Generative Ui on TypingMind?

Because you install it once and use it with any model. Generative Ui is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Generative Ui in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/himself65/finance-skills/tree/main/plugins/ui-tools/skills/generative-ui. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Generative Ui?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Generative Ui?

As many as you like. As long as a model supports skills, you can use Generative Ui with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Generative Ui AI skill free?

Yes. It is published on GitHub by himself65 under the MIT license. You only pay your own AI provider for the tokens you use.

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.

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
Text goes in your response, visuals go in the tool — all explanatory text, descriptions, and summaries must be written as normal response text OUTSIDE the tool call. The tool output should contain ONLY the visual element

Core Rules

No  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>

<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/4.5.1/chart.umd.js" onload="initChart()"></script>
<script>
function initChart() {
  // slider logic, chart rendering, sendPrompt() for follow-ups
}
if (window.Chart) initChart();
</script>

Use sendPrompt() to let users ask follow-ups: sendPrompt('What if I increase the rate to 10%?')

Step 7: Respond to the User

After rendering the widget, briefly explain:

What the widget shows
How to interact with it (which controls do what)
One key insight from the data

Keep it concise — the widget speaks for itself.
