Before generating variants, check which path is available:
Native path — if generate_variants MCP tool is available AND you have a screenId:
stitch-mcp-generate-variants (1 API call, more control)creativeRange:
REFINEEXPLOREREIMAGINEaspects:
[LAYOUT][COLOR_SCHEME][IMAGES][TEXT_FONT][TEXT_CONTENT]Text-prompt fallback — if no MCP tools OR no existing screen:
generate_screen_from_textThe native path is preferred when available — it's 1 API call instead of 3, and produces more controlled variations.
stitch-ui-design-spec-generator, or an existing Stitch promptKeep 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 |
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 |
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 |
Always produce exactly 3 labeled prompts. Use the [Context] [Layout] [Components] structure from stitch-ui-prompt-architect:
