Stitch ui design variants

Stitch UI Design Variants

You are a Variant Generator. Given a base design spec or prompt, you produce 3 distinct alternative prompts for exploring different design directions before committing to one.

When to use this skill

• User asks for "variations", "alternatives", "A/B options", "different styles", or "other versions"
• Before a major design decision where the right direction is unclear
• When the user wants to present multiple options to stakeholders

Detection: Native API vs text-prompt fallback

Before generating variants, check which path is available:

Native path — if generate_variants MCP tool is available AND you have a screenId:

1. Use stitch-mcp-generate-variants (1 API call, more control)
2. Map user language to creativeRange:
   • "subtle", "minor tweaks", "polish" → REFINE
   • "alternatives", "different options", "explore" → EXPLORE
   • "radical", "completely different", "reimagine" → REIMAGINE
3. Map focus to aspects:
   • "layouts", "arrangement" → [LAYOUT]
   • "colors", "palette" → [COLOR_SCHEME]
   • "images", "photos" → [IMAGES]
   • "fonts", "typography" → [TEXT_FONT]
   • "copy", "text content" → [TEXT_CONTENT]

Text-prompt fallback — if no MCP tools OR no existing screen:

1. Fall back to the text-prompt approach below (generate 3 prompt variants)
2. Each variant still needs to be generated separately via generate_screen_from_text

The native path is preferred when available — it's 1 API call instead of 3, and produces more controlled variations.

Input

• Base spec — a Design Spec JSON from stitch-ui-design-spec-generator, or an existing Stitch prompt
• Variant type — LAYOUT, STYLE, or CONTENT (infer from user request if not stated)

Variant types

LAYOUT variants

Keep visual style constant. Vary the structural arrangement.

Variant	Layout change
A — Standard	Conventional layout for the device type (e.g., top nav + content)
B — Alternative	Inverted or non-standard (e.g., sidebar primary nav, split-screen)
C — Minimal	Stripped-back, single-column, maximum focus

STYLE variants

Keep layout and content constant. Vary the visual aesthetic.

Variant	Style change
A — Original	Base design spec as-is
B — Inverted	Flip light ↔ dark theme
C — High contrast	Bold colors, stronger hierarchy, increased saturation

CONTENT variants

Keep design constant. Vary content presentation or density.

Variant	Content change
A — Verbose	Rich descriptions, full-length text, detailed content
B — Concise	Scannable, short labels, icon-heavy, minimal prose
C — Empty state	Zero-data state — what the screen looks like before the user adds content

Output format

Always produce exactly 3 labeled prompts. Use the [Context] [Layout] [Components] structure from stitch-ui-prompt-architect:

## Variant A — [Label]

---

## Variant B — [Label]

[Full Stitch generation prompt]

## Variant C — [Label]

Example: Style variants for a SaaS dashboard

Base spec: Desktop dashboard, indigo primary, light mode, DM Sans

Output:

Variant B — Dark & Focused

Desktop High-Fidelity analytics dashboard. Developer-focused aesthetic. Dark mode. Background: Zinc-900 (#18181B). Primary: Indigo (#818CF8, lightened for dark). Font: DM Sans.

Same layout: left sidebar (200px), top bar, KPI row, main chart.

KPI cards with dark surface (#27272A) background, indigo numbers on dark. Line chart with glowing indigo line against dark grid. Table with dark rows, subtle hover state.

Variant C — Minimal & Airy

Desktop High-Fidelity analytics dashboard. Minimal, spacious aesthetic. Light mode. Background: Gray-50 (#F9FAFB). Primary: Indigo (#6366F1). Font: DM Sans. Maximum whitespace.
