swiftui-design-skill

Type one line in your agent. Get back a SwiftUI interface that doesn't look AI-generated.

In 3 to 30 minutes, you can design a signature iOS interface — not "AI-made-it-looks-okay" quality, but something that looks like it was crafted by a designer with taste.

Anti-AI Slop 6 Iron Rules, Design Direction Advisor, Brand Asset Protocol, 5-Dimension Review — all built in. Give the skill your brand palette and it will read your vibe; give nothing and the 5 built-in design languages will still hold their ground.

Works across agents — Claude Code, Cursor, Codex, OpenCode, Hermes, all supported.

Core Mechanisms

Anti-AI Slop 6 Iron Rules

This is the hardest set of rules in the skill. All designs must pass these 6 checks:

#	Iron Rule	❌ Forbidden	✅ Alternative
1	Start from context	Inventing from a blank canvas	Ask about design system / UI kit / brand assets first
2	Junior Designer Mode	Waiting for the perfect solution	Gray placeholder > bad SVG
3	Give variants, not finals	One "final answer"	2–3 differentiated directions
4	Placeholder > bad implementation	AI-generated clip art	Clean gray placeholder + text label
5	System-first, don't fill	Packing every pixel	Every element must justify its existence
6	Ban AI slop patterns	Purple-blue gradients, emoji icons, rounded cards + left border	Single warm accent color, SF Symbols, serif headlines

See references/anti-ai-slop.md for details.

Design Direction Advisor

When requirements are vague, the skill recommends 3 differentiated directions from 5 major design schools:

School	Characteristics	Signature Style
Informational	Data-first, chart-dense	Bloomberg Terminal
Editorial	Magazine layout, serif type, generous whitespace	NYT, Medium
Expressive	Bold color, asymmetric layout, motion-forward	Stripe, Linear
Functional	Dense tool feel, monospace accents	Things, OmniFocus
Warm Minimal	Soft neutrals, rounded corners, subtle texture	Notion, Craft

Brand Asset Protocol

A mandatory 5-step hard process when working with a specific brand:

Step	Action	Purpose
1 · Ask	Does the user have brand guidelines?	Respect existing assets
2 · Search	Search the brand's official pages	Obtain real materials
3 · Download	Download actual asset files	PNG/SVG logos, fonts
4 · Verify	Verify colors match official sources	Cross-check hex values
5 · Write	Generate brand-spec.md	Record complete design system

Quality threshold: 5 real brand colors, 10 design tokens, 2 font families, 8pt spacing grid.

5-Dimension Review

Every design must pass a 5-dimension review before delivery:

Dimension	Scoring Criteria	Minimum Score
🎯 Philosophy Consistency	Does the design embody the chosen design philosophy?	≥ 7/10
📐 Visual Hierarchy	Is the information priority clear?	≥ 7/10
🔧 Detail Execution	Are spacing, typography, and colors precise?	≥ 7/10
⚡ Functionality	Does the layout serve user goals?	≥ 7/10
✨ Originality	Is there at least 1 signature detail?	≥ 7/10

Difference from swiftui-expert-skill

	SwiftUI Design Skill	swiftui-expert-skill
Focus	Visual design, aesthetics, brand feel	Code quality, performance, correctness
Question	"How does it look?"	"Is the code correct?"
Output	Design direction, color palette, layout, review	Code review, Instruments analysis, API modernization
Complementary	Use Design first to set direction	Then use Expert to ensure code quality

The two skills work together: Design decides what to build, Expert ensures how to build it right.
