Meng To's UI Prompting Skill

This skill is for design-first prompting: turn fuzzy ideas into a tight spec that produces consistent UI.

Core principle

Prompt like a design system, not a wish.

The Meng To prompt structure (copy/paste)

Use this skeleton, then fill the blanks.

GOAL
- What are we making? (e.g., landing page hero / onboarding / dashboard / carousel slide)
- Who is it for? (persona)
- What's the success criteria? (clarity, conversion, vibe)

FORMAT
- Size/aspect: (e.g., 1080x1350)
- Safe margins: (e.g., 90px)

LAYOUT (wireframe in words)
- Grid: (e.g., Swiss 6-col)
- Placement: (e.g., type-left / image-right)
- Hierarchy: H1 → subhead → body → CTA

TYPE SYSTEM
- Font vibe: (e.g., Söhne / Neue Haas / SF Pro)
- Weights: (H1 700, body 400)
- Leading: (tight for H1, readable for body)
- Tracking: (micro labels wider)

COLOR + MATERIAL
- Background: (hex or description)
- Text: (white/ivory/charcoal)
- One accent only: (cyan/lime/purple)
- Texture: (subtle grain, no plastic HDR)

IMAGERY / UI STYLE
- UI style: (minimal / glass / editorial / playful 3D)
- If photo: lighting + crop + texture rules
- If 3D: materials + lighting + softness

COPY (render EXACTLY)
- Line 1:
- Line 2:
- ...

CONSTRAINTS (change 1–2 things only)
- FONT: ___
- STYLE: ___
- MODE: ___

NEGATIVE PROMPT
- No logos, no watermarks
- No extra text beyond provided lines
- No gibberish typography

Rules that improve consistency

1) Lock one "system", then iterate with variants

• First output: nail layout + hierarchy + copy.
• Variants: change ONE variable at a time (angle/crop, accent color, card arrangement, background tone).

2) Treat typography as fragile

If the model keeps misspelling:

• Use 2-pass workflow:
  1. Generate without text (reserve a clean text-safe area)
  2. Typeset in Figma

3) Use "constraints cards"

When you want the model to obey a style, add a small "Constraints" panel with explicit values.

4) Keep a private reference pack

Don't ask the model to "remember" taste. Save references into refs/... and point prompts to the reference style.

Fast iteration checklist

• Spacing: margins, leading, baseline rhythm
• Contrast: background vs text
• Hierarchy: one hero line, one support line
• One accent only (don't rainbow)
• Texture: add grain, remove smoothing

Tips for AI Agents

• Always ask for the single message of the screen before designing.
• Confirm hierarchy (H1 / sub / CTA) before generating layouts.
• Choose a style lane early: minimal editorial vs playful 3D vs glass UI.
