Design Canvas Artifact

Use this private product-design skill when the user asks for UI design, product design, mobile app screens, web design mockups, dashboard design, visual variants, HTML design prototypes, or iterative design edits from screenshots/sketch annotations.

Intent

The deliverable is a reviewable design artifact, not a production application. The output should make design decisions visible: screens, states, variants, assumptions, visual systems, and tradeoffs should be placed on a canvas where the user and AI can compare them.

Output Contract

Generate one standalone HTML file that:

• Embeds its own design canvas structure with sections and fixed-size artboards.
• Defines clear local primitives such as DesignCanvas, DCViewport, DCSection, and DCArtboard, or equivalent names with the same meaning.
• Uses transform-based canvas navigation for the main board: translate3d(x, y, 0) scale(scale).
• Supports trackpad pinch zoom, two-finger pan, and blank-space drag pan without browser-window scrollbars.
• Posts host synchronization messages when JavaScript is enabled: __dc_present on mount and __dc_zoom when scale changes; listens for __dc_set_zoom.
• Shows important screens and states side by side.
• Uses stable section ids, artboard ids, labels, and component names.
• Keeps visual variants aligned by information architecture while changing visual language.
• Includes a compact brief or design-system artboard when useful.
• Runs locally in a browser without backend services.
• Avoids local absolute file paths.

Design Rules

• For mobile app work, prefer phone artboards around 393x852 unless the brief names another device.
• For web or dashboard work, use explicit desktop/tablet/mobile artboards when responsive decisions matter.
• Do not hide key states behind routing or tabs. The artifact should support design review at a glance.
• Use lightweight demo interactions only when they clarify a state. Do not build complete business logic.
• Hide scrollbars on the main canvas and artboards. Only keep internal scrolling when the designed screen itself needs to demonstrate scroll behavior.
• Prefer structured reusable components for repeated screens so later AI edits can target the design cleanly.
• If sketch annotations, screenshots, or exported tldraw images are present, interpret them as design feedback and modify the corresponding artboards.

Code Generation Handoff

When invoking the private design code generation agent, include:

• The user request and selected assumptions.
• The target surface and artboard sizes.
• Required screens, states, and variants.
• Selected visual direction or design system.
• Relevant uploaded files, screenshots, sketch exports, or annotation notes.
• Validation expectations such as "standalone HTML", "visible text", and "no local absolute paths".
