- Create shareable HTML canvases via the gui.new API. Use when: (1) generating visual output (dashboards, charts, forms, tables, diagrams, landing pages, interactive tools), (2) user asks to share or preview HTML as a live link, (3) user wants to turn code output into something viewable by others, (4) creating Mermaid diagrams as shareable links. POST HTML, get a live URL with real-time input sync and state persistence built in.
gui.new
HTML in, URL out. One API call turns HTML into a shareable link.

Security Note
This skill sends HTML content to https://gui.new, a third-party hosted service. Do not send sensitive, private, or confidential data. Canvases are publicly accessible via their URL. Links expire (24h free, up to 30d Pro).
Built-in Components (auto-injected)
Use these tags directly — no script imports needed:
<gui-chart type="bar" data='[{"label":"Q1","value":42}]'><gui-table data='[{"name":"Alice","role":"Eng"}]'><gui-card title="Metric" value="1,247" change="+12%"><gui-code language="javascript">code</gui-code><gui-timeline data='[{"date":"Mar 1","title":"Launch"}]'><gui-kanban columns='[{"title":"Todo","items":["Task 1"]}]'><gui-form fields='[{"name":"email","type":"email","label":"Email"}]'><gui-grid columns="3">content</gui-grid>
Real-Time Sync
All form inputs (text, range, select, checkbox) sync across viewers automatically. No setup needed.
