Design system and guidelines for Claude's built-in showwidget tool to render high-quality interactive HTML/SVG widgets, charts, diagrams, and explainers inline.

  • The user asks for generative ui design system work
  • SKILL.md covers Instructions, Always, Never and Examples, plus 1 more section
  • Calls npx
  • Tasks that involve Diagrams

What it does

Fin Generative UI is an agent skill from criptogus/agent-evolve-network. Design system and guidelines for Claude's built-in showwidget tool to render high-quality interactive HTML/SVG widgets, charts, diagrams, and explainers inline. Use when the user asks for generative ui design system work, or mentions fin, generative, ui.

Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Diagrams, UI design and HTML artifacts. It works with Chart.js. The licence is MIT.

When your agent uses it

  • The user asks for generative ui design system work
  • Tasks that involve Diagrams
  • Tasks that involve UI design

Example prompts

  • “/fin-generative-ui”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit d19b920. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • superagentskill.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Fin Generative UI loads about 972 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 409 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~972

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Generative UI Design System

Use this skill whenever the user wants visual or interactive output beyond plain text: visualize data, build an interactive chart or dashboard, render a diagram or flowchart, show a mockup, create an interactive explainer, or build tools with sliders/toggles/live displays. It also applies to displaying financial data visually and comparison grids.

It provides the Anthropic "Imagine" design system for the show_widget tool (which renders raw HTML/SVG inline in claude.ai), so Claude can produce high-quality widgets directly without a setup call. It covers picking the right visual type (route on the verb), widget structure and core rules, the CSP-enforced CDN allowlist and CSS variables, sendPrompt for interactivity, and templates for Chart.js charts, SVG diagrams, and interactive explainers.

Instructions

You are a generative-UI designer using Claude's built-in show_widget tool (renders HTML/SVG inline). Step 1 - Pick the right visual type by routing on the verb, not the noun: "how does X work" -> illustrative SVG diagram; "X architecture" -> structural SVG; "what are the steps" -> SVG flowchart; "explain X" -> interactive HTML explainer; "compare options" -> HTML comparison grid; "show revenue chart" -> Chart.js (HTML); "contact card" -> HTML data record; "draw a sunset" -> SVG art. Step 2 - Build the widget in strict structure order following the design philosophy and core rules. Only use libraries on the CSP-enforced CDN allowlist. Use the provided CSS variable system for colors/spacing. Use sendPrompt(text) to wire interactive controls back into the conversation. Step 3 - Render with show_widget (raw HTML/SVG fragment). Step 4 - Use the appropriate template: Chart.js for charts, SVG for diagrams, interactive HTML for explainers. Step 5 - Respond to the user with the rendered widget and a brief explanation. Follow the Imagine design rules for high visual quality; respect the CDN allowlist and CSS variables.

Always

  • Route the visual type on the verb (how/architecture/steps/explain/compare/show), not the noun.
  • Only load libraries from the CSP-enforced CDN allowlist and use the design-system CSS variables.
  • Render via show_widget and follow the strict widget structure order.

Never

  • Load scripts or assets from outside the CDN allowlist.
  • Return a wall of text when an interactive widget was requested.

Examples

Chart

Input:

Show me a revenue chart for these quarterly figures

Expected output:

Routes to a Chart.js HTML widget using the allowed CDN and CSS variables, renders it via show_widget,
and gives a one-line summary of the trend.
Interactive explainer

Input:

Explain compound interest interactively

Expected output:

Builds an interactive HTML explainer with sliders wired via sendPrompt, renders via show_widget, and
briefly explains how to use the controls.
