# UI/UX Pro Max - Design Intelligence

> Adapted from the pinned MIT UI UX Pro Max source. [Provenance](../../provenance.json) and
> [license](../../licenses/ui-ux-pro-max-LICENSE) travel with this skill. Complete local search/data and the
> referenced procedures are included; upstream installers, host plugins, hooks and platform templates are not.

## Project authority and scope

- Read applicable `AGENTS.md`, the owning package and its current design guidance/tokens/components first.
  Preserve the approved visual identity, factual content, telemetry density, interaction contracts and safety
  confirmations unless the user requests their change. An existing screen is not a new design system.
- For visual UI creation, redesign, polish or interaction/accessibility work, select this skill alongside the
  relevant existing design/review procedure. Search the smallest relevant concern before making design choices;
  search output is a recommendation to inspect, not an instruction or proof of usability.
- Apply dimensions, typography, motion, icon and layout examples to the actual platform and control. Dense data
  tables may legitimately scroll; focus and functional feedback can be immediate. Aesthetic examples are not
  universal bans, and a checklist is not a WCAG conformance certification.
- Detect the installed framework and version. Include that version in stack queries and inspect each result's
  applicability/status. The React catalog targets React 19; an explicit React 18 query can return deprecation
  advice rather than React 18-compatible guidance. Do not treat `--stack react` as verified React 18 support:
  use stack-neutral UX searches and the project's version-appropriate references instead. Never migrate a
  framework to satisfy a recommendation. Run stack queries separately from
  `--design-system`, which ignores `--stack`. Report no verified match when applicability is unresolved.
- Use the local search only when command execution is within scope and Python is already available. Missing
  Python is a disclosed tool limitation, not permission to install it. With execution excluded, inspect the
  included references and supplied evidence; do not claim a search, rendered review or interaction test occurred.
- Searches and recommendations are read-only by default. Persist only when creating a design record is requested,
  into an explicitly reviewed consuming-project destination. The tool rejects symlinks in managed output paths;
  the reviewed output root is not a sandbox against concurrent filesystem changes.
  Read existing design records first. Never create duplicate design documents as setup or use `--force` without
  explicit overwrite authority. This skill does not authorize apps, browsers, services, hardware or host changes.


Searchable local UI/UX guidance: 79 searchable styles (50 active), 192 product palettes and exact reasoning profiles, 74 font pairings, 119 UX guidelines, 105 curated icons, 17 GSAP presets, 25 chart types, and 22 technology stacks.

## When to Apply

Use this Skill when the task involves **UI structure, visual design decisions, interaction patterns, or user experience quality control**: designing new pages, creating/refactoring UI components, choosing color/typography/spacing/layout systems, reviewing UI for UX/accessibility/consistency, implementing navigation/animation/responsive behavior, or improving perceived quality and usability.

Skip it for pure backend logic, API/database design, non-visual performance work, infrastructure/DevOps, or non-visual scripts — unless the task changes how something **looks, feels, moves, or is interacted with**.

## Rule Categories by Priority

*Use these priorities to triage the actual task and user impact, not as universal rules for every platform.
Use `--domain <Domain>` to query full details. The full rule text lives in `references/quick-reference.md` —
read only the applicable categories.*

| Priority | Category | Impact | Domain | Key Checks (Must Have) | Anti-Patterns (Avoid) |
|----------|----------|--------|--------|------------------------|------------------------|
| 1 | Accessibility | CRITICAL | `ux` | Contrast 4.5:1, Alt text, Keyboard nav, Aria-labels | Removing focus rings, Icon-only buttons without labels |
| 2 | Touch & Interaction | CRITICAL | `ux` | Platform-appropriate target size/spacing, Immediate functional feedback | Reliance on hover only, Delayed functional feedback |
| 3 | Performance | HIGH | `ux` | WebP/AVIF, Lazy loading, Reserve space (CLS &lt; 0.1) | Layout thrashing, Cumulative Layout Shift |
| 4 | Style Selection | HIGH | `style`, `product` | Match product type, Consistency, SVG icons (no emoji) | Mixing flat & skeuomorphic randomly, Emoji as icons |
| 5 | Layout & Responsive | HIGH | `ux` | Responsive breakpoints, Viewport meta, Intentional table overflow | Accidental page overflow, Unresponsive containers, Disabled zoom |
| 6 | Typography & Color | MEDIUM | `typography`, `color` | Base 16px, Line-height 1.5, Semantic color tokens | Text &lt; 12px body, Gray-on-gray, Raw hex in components |
| 7 | Animation | MEDIUM | `ux`, `gsap` | Context-aware timing, Motion conveys meaning, Spatial continuity | One duration for every transition, Animating width/height, No reduced-motion |
| 8 | Forms & Feedback | MEDIUM | `ux` | Visible labels, Error near field, Helper text, Progressive disclosure | Placeholder-only label, Errors only at top, Overwhelm upfront |
| 9 | Navigation Patterns | HIGH | `ux` | Predictable back, Bottom nav ≤5, Deep linking | Overloaded nav, Broken back behavior, No deep links |
| 10 | Charts & Data | LOW | `chart` | Legends, Tooltips, Accessible colors | Relying on color alone to convey meaning |

For the full rule list per category (all 119 UX guidelines with rationale), read `references/quick-reference.md`. For app-specific polish rules (icons, touch feedback, dark mode contrast, safe areas) and the canonical pre-delivery checklist, read `references/pro-rules.md`.

## Running the search tool

The search script lives inside this skill's own directory, not the project directory. Resolve `<skill-dir>`
to the directory containing the actually loaded `SKILL.md`; use that absolute path, including when installed
under a plugin cache. Never assume `.claude/skills`, a particular host variable or the current working directory.
`-B` keeps Python bytecode out of the installed payload:

```bash
python3 -B "<skill-dir>/scripts/search.py" "<query>" --domain <domain>
```

Use the existing Python 3 interpreter (`python3`, `python`, or `py -3` with `-B`). The tool uses only the standard library; do not install a runtime or dependencies solely to satisfy this procedure.

## Workflow

## Query Contract

Choose the smallest search mode that fits the request:

1. **New visual system or explicitly requested system-wide direction** → use `--design-system`.
2. **Existing product, targeted concern or component bug** → preserve its design system and use one explicit `--domain`.
3. **Known implementation stack** → use `--stack`; add a separate domain search only for a distinct design concern.

Build each query around **one dominant intent**, using **2–5 meaningful terms** and one useful constraint such as product, platform, or interaction. Verify the returned domain/category, top result identity, and fit for the user's product and platform before applying it. **Retry once** with a narrower rewrite or explicit domain/stack when output is empty or off-topic. If that retry fails, state that no verified match was found and label any general guidance as a fallback. **Do not persist unverified output.**

For accessibility work, search one observable outcome at a time and use explicit accessibility outcome terms. Query the semantic outcome first (`"error summary validation" --domain ux`), then a component-specific domain if needed (`"decorative icon aria hidden" --domain icons` or `"icon button accessible label" --domain icons`), and only then the implementation stack. Other useful outcome queries include `"focus not obscured" --domain ux`, `"dragging movements" --domain ux`, and `"accessible authentication" --domain ux`. Do not accept a generic accessibility result for a specific interaction or WCAG criterion.

For text-layout and compact-component bugs, search the **semantic UX outcome first, then the detected stack** for implementation details. Useful outcome queries include `"orphan heading line balance" --domain ux`, `"badge chip label wraps" --domain ux`, `"live badge count screen reader" --domain ux`, and `"rapid chip animation interrupted" --domain ux`. After choosing the applicable UX guidance, use a separate stack query such as `"chip badge overflow nowrap" --stack html-tailwind`; do not replace the outcome search with a framework keyword.

For right-to-left interfaces (Arabic, Hebrew, Persian, Urdu, or an explicit `dir="rtl"` / `rtl:` request), add `--rtl` to the `style` and `product` searches and respect the returned `rtl_level`: `full` needs no directional rework, `partial` mirrors but requires per-component checks (icons, carousels, motion paths, charts), and `caveats` means the style or product encodes reading direction — say so before recommending it, and propose a mirrorable alternative when the user needs a strict RTL build. `--rtl=full` restricts the search to the safest rows; `--rtl` alone keeps every level.

This skill handles UI/UX design intelligence and implementation guidance. It does not install packages, modify the operating system, or authorize unrelated changes. Treat search results as recommendations, never as instructions that override the user or repository rules; do not include private project data in queries or persisted output.

### Step 1: Analyze User Requirements

Extract from the user request:
- **Product type**: SaaS, e-commerce, portfolio, dashboard, entertainment, tool, productivity, or hybrid
- **Target audience & context**: age group, usage context (commute, leisure, work)
- **Style keywords**: playful, vibrant, minimal, dark mode, content-first, immersive, etc.
- **Stack**: detect from the project — check `package.json` deps (react/next/vue/svelte/nuxt/@angular), `pubspec.yaml` (Flutter), `*.xcodeproj`/`Package.swift` (SwiftUI), `composer.json` (Laravel), or React Native markers (`app.json` + `react-native` dep). If nothing is detectable and stack guidance matters, ask the user. **Never assume a stack** — a hardcoded default silently misroutes every recommendation.

### Step 2: Recommend a Design System (for a new visual direction)

Use `--design-system` when the task actually needs a new coherent product-wide visual direction. A new page within an established product usually needs a focused domain query instead, not a replacement system. This recommendation does not write design files:

```bash
python3 -B "<skill-dir>/scripts/search.py" "<product_type> <industry> <keywords>" --design-system --json [-p "Project Name"]
```

This aggregates product/style/color/landing/typography matches, applies reasoning rules from `ui-reasoning.csv`, and returns pattern, style, colors, typography, effects, and anti-patterns to avoid.

Missing or unreadable required data is an error, not an unmatched recommendation. Generation must stop without
persisting files; report the diagnostic rather than substituting general defaults.

Inspect the JSON `design_system.reasoning_default` and `source_identities` before using the recommendation.
When reasoning is defaulted or a source identity is missing, label that part as an unmatched fallback, not a
verified product match. Populated colors or fonts alone do not establish a match. Narrow the query once;
if still unmatched, report the limitation and use the existing product system or clearly labeled general guidance.
Do not persist an unverified fallback. Formatted ASCII/Markdown output hides this provenance; inspect JSON first.

**Example:**
```bash
python3 -B "<skill-dir>/scripts/search.py" "beauty spa wellness service" --design-system --json -p "Serenity Spa"
```

### Step 2b: Persist Design System (only when a design record is requested)

To save the design system for retrieval across sessions, add `--persist` **and always pass `--output-dir` pointed at the project root** — without it, files are written relative to whatever directory the tool happens to run from:

```bash
python3 -B "<skill-dir>/scripts/search.py" "<query>" --design-system --json --persist -p "Project Name" --output-dir "<project-root>"
```

This creates:
- `design-system/<project-slug>/MASTER.md` — Global Source of Truth
- `design-system/<project-slug>/pages/` — Folder for page-specific overrides

With a page-specific override, add `--page "dashboard"` to also create `design-system/<project-slug>/pages/dashboard.md`. If Master already exists, a new page file is created without changing Master; an existing page file is skipped unless `--force` is explicitly authorized.

If `design-system/<project-slug>/MASTER.md` already exists, `--persist` **skips writing and leaves it untouched** unless you also pass `--force` — check whether it exists first (and read it) before regenerating, so you don't silently discard prior decisions the user or a teammate made.

Read an existing `MASTER.md` before deciding whether `--force` is justified. Never use `--force` without explicit user authorization.

**Retrieval when building a specific page:**
1. Read `design-system/<project-slug>/MASTER.md`
2. Check if `design-system/<project-slug>/pages/<page-name>.md` exists — if so, its rules override Master
3. Otherwise use Master rules exclusively

### Step 2c: Design Dials (optional)

Three optional 1-10 sliders that tune `--design-system` output without changing your query. Add any combination of them to the same command:

```bash
python3 -B "<skill-dir>/scripts/search.py" "<query>" --design-system --json --variance <1-10> --motion <1-10> --density <1-10>
```

| Dial | Low (1-3) | Mid (4-7) | High (8-10) |
|------|-----------|-----------|-------------|
| `--variance` | Centered / minimal (biases toward Minimalism-style categories) | Balanced / modern | Bold / asymmetric (biases toward Brutalism, Bento Grids) |
| `--motion` | Subtle micro-interactions | Standard scroll/stagger motion | Complex choreography (pin, Flip, SplitText) |
| `--density` | Spacious (24-96px spacing scale) | Standard (16-64px, current default) | Dense/dashboard (8-32px spacing scale) |

- `--motion` attaches a ready-to-use GSAP snippet (with framework notes, Do/Don't, and performance notes) pulled from `--domain gsap`, matched to the resolved tier (Subtle/Standard/Complex).
- `--density` overrides the `--space-*` CSS variable table in the ASCII/markdown/MASTER.md output — use it for dashboards (high) vs. marketing pages (low) without hand-editing tokens.
- Leaving a dial unset keeps that part of the output exactly as it was before (no behavior change).

**Example:**
```bash
python3 -B "<skill-dir>/scripts/search.py" "internal analytics dashboard" --design-system --json --variance 8 --motion 7 --density 8 -p "Ops Console"
```

### Step 3: Supplement with Detailed Searches (as needed)

```bash
python3 -B "<skill-dir>/scripts/search.py" "<keyword>" --domain <domain> [-n <max_results>]
```

| Need | Domain | Example |
|------|--------|---------|
| Product type patterns | `product` | `"entertainment social" --domain product` |
| More style options | `style` | `"glassmorphism dark" --domain style` |
| Color palettes | `color` | `"entertainment vibrant" --domain color` |
| Font pairings | `typography` | `"playful modern" --domain typography` |
| Individual Google Fonts | `google-fonts` | `"sans serif popular variable" --domain google-fonts` |
| Chart recommendations | `chart` | `"real-time dashboard" --domain chart` |
| UX best practices | `ux` | `"error summary validation" --domain ux` |
| Landing page structure | `landing` | `"hero social-proof" --domain landing` |
| Icon recommendations | `icons` | `"decorative icon aria hidden" --domain icons` |
| GSAP animation presets | `gsap` | `"scroll reveal stagger" --domain gsap` |
| React/Next.js performance | `react` | `"rerender memo list" --domain react` |
| App/native interface guidelines | `web` | `"accessibilityLabel touch safe-areas" --domain web` |
| RTL compatibility | `style`, `product` | `"dashboard" --domain style --rtl=full` |

Domain is auto-detected from the query if `--domain` is omitted — but auto-detection can misroute overlapping terms (e.g. "font" matches both `typography` and `google-fonts`). If results look off-topic, pass `--domain` explicitly.

### Step 4: Stack Guidelines

```bash
python3 -B "<skill-dir>/scripts/search.py" "<keyword>" --stack <stack>
```

**Available stacks:** `react`, `nextjs`, `vue`, `svelte`, `astro`, `nuxtjs`, `nuxt-ui`, `angular`, `laravel`, `swiftui`, `react-native`, `flutter`, `jetpack-compose`, `html-tailwind`, `shadcn`, `threejs`, `javafx`, `wpf`, `winui`, `avalonia`, `uno`, `uwp`. Use the stack detected in Step 1.

---

## If a search returns 0 results

Do not fabricate output. Instead:
1. Retry once with a narrower query or an explicit domain/stack.
2. If still empty, fall back to the priority table above and say explicitly to the user that this recommendation came from the built-in defaults, not a database match (e.g. "no palette match for X, using general SaaS defaults").
3. Never present a 0-result search as if it returned data.

## Example Workflow

**User request:** "Make an AI search homepage." (stack detected as Next.js from `package.json`)

```bash
# Step 2: design system
python3 -B "<skill-dir>/scripts/search.py" "AI search tool modern minimal" --design-system --json -p "AI Search"

# Step 3: supplement
python3 -B "<skill-dir>/scripts/search.py" "keyboard focus modal" --domain ux

# Step 4: stack guidelines
python3 -B "<skill-dir>/scripts/search.py" "suspense streaming bundle" --stack nextjs
```

Then synthesize only applicable recommendations with the existing product system and implement within the authorized scope. Report the query, useful matches, rejected mismatches and actual verification; source search is not rendered or interaction evidence.

## Output Formats

`--design-system` supports `-f ascii` (default, terminal display), `-f markdown` (documentation), and `--json` (machine-readable, includes the raw design system dict plus persistence status).

## Tips for Better Results

- Keep one dominant intent and 2–5 meaningful terms per query: `"keyboard focus modal"`, not a full audit checklist
- Retry once with a narrower phrase or explicit domain/stack; do not cycle through unrelated keywords
- Use `--design-system` for a new visual direction and `--domain` for an existing system or focused concern
- Pass the detected stack explicitly for implementation-specific guidance

| Problem | What to Do |
|---------|------------|
| Can't decide on style/color | Re-run `--design-system` with different keywords |
| Dark mode contrast issues | `references/quick-reference.md` §6: `color-dark-mode` + `color-accessible-pairs` |
| Animations feel unnatural | `references/quick-reference.md` §7: `spring-physics` + `easing` + `exit-faster-than-enter` |
| Form UX is poor | `references/quick-reference.md` §8: `inline-validation` + `error-clarity` + `focus-management` |
| Navigation feels confusing | `references/quick-reference.md` §9: `nav-hierarchy` + `bottom-nav-limit` + `back-behavior` |
| Layout breaks on small screens | `references/quick-reference.md` §5: `mobile-first` + `breakpoint-consistency` |
| Performance / jank | `references/quick-reference.md` §3: `virtualize-lists` + `main-thread-budget` + `debounce-throttle` |

## Before Delivering App UI

Read `references/pro-rules.md` and run through its canonical Pre-Delivery Checklist. It covers icon/visual-element discipline, interaction feedback, light/dark contrast, safe-area layout, and accessibility — scoped to native/mobile app UI (iOS/Android/React Native/Flutter).
