Individual skill

generative-ui

Design system and templates for interactive HTML/SVG visuals in Claude and Codex, using an available inline renderer or a standalone HTML file. 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.

**Codex and other hosts**: First check the available tools. Use the host's documented visualization interface when provided; otherwise save a complete HTML document in the workspace and return a clickable file link. For standalone output, the fragment-only rule below does not apply: include a document wrapper and viewport metadata, define the CSS variables and SVG classes used by the templates (including dark-mode colors), and load chart dependencies explicitly. The host-specific CDN allowlist and injected styles below describe Claude's renderer; they are not Codex capabilities. Remove chat follow-up buttons and `sendPrompt` handlers when that bridge is unavailable; keep local sliders and calculations functional. Verify the saved output in a browser when available.

## Step 1: Pick the Right Visual Type

Route on the **verb**, not the noun. Same subject, different visual depending on what was asked:
