How to Use

Search specific domains using the CLI tool below.

---

Prerequisites

Requires python3 (available by default in the Claude Code shell and in claude.ai's code-execution sandbox). This skill does not install anything.

Always pass -f markdown on --design-system. The default is ascii, which is built for a terminal: it emits about 7,000 bytes carrying raw ANSI colour escapes, and hex_to_ansi has no isatty guard, so those escapes survive being piped and land in the context window as garbage. -f markdown returns the same information in about 2,100 bytes of clean markdown. The consumer here is a model, not a terminal, so this is a 3.3x token reduction on the most-run command in this skill.

How to Use This Skill

When user requests UI/UX work (design, build, create, implement, review, fix, improve), follow this workflow:

Every command below runs in the same shell call as this block. Shell state does not survive between calls, and the working directory is not guaranteed to either, so UIUX_DIR is derived again each time and every command names the script by its full path. The block tries, in order: $SKILL_BASE/ui-ux-pro-max when an orchestrator's skill-base block ran earlier in the same call; a directory you name yourself by putting UIUX_DIR='/absolute/path/to/ui-ux-pro-max' in front of the block; this skill's own directory when the host substitutes CLAUDE_SKILL_DIR (a standalone install); then a bounded search of the usual skills directories. When you already know the absolute path, you may write it in place of $UIUX_DIR.

# Commands run from the project, so --persist writes to the project root and
# never into the skill directory.
PROJECT_ROOT="$PWD"
uiux_given="${UIUX_DIR:-}"
UIUX_DIR=""
for uiux_c in "${SKILL_BASE:+$SKILL_BASE/ui-ux-pro-max}" "$uiux_given" "${CLAUDE_SKILL_DIR}"; do
  [ -n "$uiux_c" ] && [ -f "$uiux_c/scripts/search.py" ] && { UIUX_DIR="$uiux_c"; break; }
done
if [ -z "$UIUX_DIR" ]; then
  for uiux_root in "$HOME/.agents/skills" "$HOME/.claude/skills" "$HOME/.claude/plugins" /mnt/skills; do
    [ -d "$uiux_root" ] || continue
    uiux_hit="$(find -L "$uiux_root" -maxdepth 9 -type f -path '*/ui-ux-pro-max/scripts/search.py' 2>/dev/null | sort -V | tail -1)"
    [ -n "$uiux_hit" ] && { UIUX_DIR="${uiux_hit%/scripts/search.py}"; break; }
  done
fi
[ -n "$UIUX_DIR" ] || echo "genjutsu: ui-ux-pro-max not found. Say so in one line and derive the design system from the thesis by hand." >&2

Step 1: Analyze User Requirements

Extract key information from user request:

• Product type: SaaS, e-commerce, portfolio, dashboard, landing page, etc.
• Style keywords: minimal, playful, professional, elegant, dark mode, etc.
• Industry: healthcare, fintech, gaming, education, etc.
• Stack: React, Vue, Next.js, or default to html-tailwind

Step 2: Generate Design System (REQUIRED)

Always start with --design-system to get comprehensive recommendations with reasoning:

python3 "$UIUX_DIR/scripts/search.py" "<product_type> <industry> <keywords>" --design-system [-p "Project Name"] -f markdown

This command:

1. Searches 5 domains in parallel (product, style, color, landing, typography)
2. Applies reasoning rules from ui-reasoning.csv to select best matches
3. Returns complete design system: pattern, style, colors, typography, effects
4. Includes anti-patterns to avoid

Example:

python3 "$UIUX_DIR/scripts/search.py" "beauty spa wellness service" --design-system -p "Serenity Spa" -f markdown

Step 2b: Persist Design System (Master + Overrides Pattern)

To save the design system for hierarchical retrieval across sessions, add --persist (point --output-dir at the project root so files land there, not in the skill dir):

python3 "$UIUX_DIR/scripts/search.py" "<query>" --design-system --persist -p "Project Name" --output-dir "$PROJECT_ROOT" -f markdown

This creates:

• design-system/<project-slug>/MASTER.md - Global Source of Truth with all design rules
• design-system/<project-slug>/pages/ - Folder for page-specific overrides

--persist skips writing if MASTER.md already exists; add --force to overwrite.

With page-specific override:

python3 "$UIUX_DIR/scripts/search.py" "<query>" --design-system --persist -p "Project Name" --page "dashboard" --output-dir "$PROJECT_ROOT" -f markdown

This also creates:

• design-system/<project-slug>/pages/dashboard.md - Page-specific deviations from Master

How hierarchical retrieval works:

1. When building a specific page (e.g., "Checkout"), first check design-system/<project-slug>/pages/checkout.md
2. If the page file exists, its rules override the Master file
3. If not, use design-system/<project-slug>/MASTER.md exclusively

Context-aware retrieval prompt:

I am building the [Page Name] page. Please read design-system/MASTER.md.
Also check if design-system/pages/[page-name].md exists.
If the page file exists, prioritize its rules.
If not, use the Master rules exclusively.
Now, generate the code...

Step 3: Supplement with Detailed Searches (as needed)

After getting the design system, use domain searches to get additional details:

python3 "$UIUX_DIR/scripts/search.py" "<keyword>" --domain <domain> [-n <max_results>]

When to use detailed searches:

Need	Domain	Example
More style options	style	--domain style "glassmorphism dark"
Chart recommendations	chart	--domain chart "real-time dashboard"
UX best practices	ux	--domain ux "animation accessibility"
Alternative fonts	typography	--domain typography "elegant luxury"
Landing structure	landing	--domain landing "hero social-proof"

Step 4: Stack Guidelines (Default: html-tailwind)

Get implementation-specific best practices. If user doesn't specify a stack, default to html-tailwind.

python3 "$UIUX_DIR/scripts/search.py" "<keyword>" --stack html-tailwind

Available stacks: html-tailwind, react, nextjs, astro, vue, nuxtjs, nuxt-ui, svelte, swiftui, react-native, flutter, shadcn, jetpack-compose, threejs, angular, laravel, javafx, wpf, winui, avalonia, uno, uwp

Example Workflow

User request: "Build a landing page for a professional skincare service"

Step 1: Analyze Requirements

• Product type: Beauty/Spa service
• Style keywords: elegant, professional, soft
• Industry: Beauty/Wellness
• Stack: html-tailwind (default)

Step 2: Generate Design System (REQUIRED)

python3 "$UIUX_DIR/scripts/search.py" "beauty spa wellness service elegant" --design-system -p "Serenity Spa" -f markdown

Output: Complete design system with pattern, style, colors, typography, effects, and anti-patterns.

Step 3: Supplement with Detailed Searches (as needed)

# Get UX guidelines for animation and accessibility
python3 "$UIUX_DIR/scripts/search.py" "animation accessibility" --domain ux

# Get alternative typography options if needed
python3 "$UIUX_DIR/scripts/search.py" "elegant luxury serif" --domain typography

Step 4: Stack Guidelines

python3 "$UIUX_DIR/scripts/search.py" "layout responsive form" --stack html-tailwind

Then: Synthesize design system + detailed searches and implement the design.

---

Output Formats

The --design-system flag supports two output formats:

# ASCII box (default) - best for terminal display
python3 "$UIUX_DIR/scripts/search.py" "fintech crypto" --design-system -f markdown

# Markdown - best for documentation
python3 "$UIUX_DIR/scripts/search.py" "fintech crypto" --design-system -f markdown

---

Tips for Better Results

1. Be specific with keywords - "healthcare SaaS dashboard" > "app"
2. Search multiple times - Different keywords reveal different insights
3. Combine domains - Style + Typography + Color = Complete design system
4. Always check UX - Search "animation", "z-index", "accessibility" for common issues
5. Use stack flag - Get implementation-specific best practices
6. Iterate - If first search doesn't match, try different keywords

Common Rules for Professional UI

These are frequently overlooked issues that make UI look unprofessional:

Icons & Visual Elements

Rule	Do	Don't
No emoji icons	Use SVG icons (Heroicons, Lucide, Simple Icons)	Use emojis like 🎨 🚀 ⚙️ as UI icons
Stable hover states	Use color/opacity transitions on hover	Use scale transforms that shift layout
Correct brand logos	Research official SVG from Simple Icons	Guess or use incorrect logo paths
Consistent icon sizing	Use fixed viewBox (24x24) with w-6 h-6	Mix different icon sizes randomly

Interaction & Cursor

Rule	Do	Don't
Cursor pointer	Add cursor-pointer to all clickable/hoverable cards	Leave default cursor on interactive elements
Hover feedback	Provide visual feedback (color, shadow, border)	No indication element is interactive
Smooth transitions	Use transition-colors duration-200	Instant state changes or too slow (>500ms)

Light/Dark Mode Contrast

Rule	Do	Don't
Glass card light mode	Use bg-white/80 or higher opacity	Use bg-white/10 (too transparent)
Text contrast light	Use #0F172A (slate-900) for text	Use #94A3B8 (slate-400) for body text
Muted text light	Use #475569 (slate-600) minimum	Use gray-400 or lighter
Border visibility	Use border-gray-200 in light mode	Use border-white/10 (invisible)

Layout & Spacing

Rule	Do	Don't
Floating navbar	Add top-4 left-4 right-4 spacing	Stick navbar to top-0 left-0 right-0
Content padding	Account for fixed navbar height	Let content hide behind fixed elements
Consistent max-width	Use same max-w-6xl or max-w-7xl	Mix different container widths
