Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00162 | $0.03361 |
| Opus 5 | $0.00081 | $0.01681 |
| Sonnet 5 | $0.00032 | $0.00672 |
| Haiku 4.5 | $0.00016 | $0.00336 |
Grade A, and why
ui-ux-pro-max scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
95% identical to ui-ux-pro-max — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UI/UX Pro Max - Design Intelligence
Searchable database of UI/UX design rules with priority-based recommendations: 84 styles, 192 color palettes, 74 font pairings, 192 product types with reasoning rules, 99 UX guidelines, 105 icon entries, 16 GSAP motion presets, and 25 chart types across 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
Follow priority 1→10 to decide which category to focus on first; use --domain <Domain> to query full details. The full rule text for every category lives in references/quick-reference.md — read it on demand rather than loading it every time.
| 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 |
Min size 44×44px, 8px+ spacing, Loading feedback | Reliance on hover only, Instant state changes (0ms) |
| 3 | Performance | HIGH | ux |
WebP/AVIF, Lazy loading, Reserve space (CLS < 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 |
Mobile-first breakpoints, Viewport meta, No horizontal scroll | Horizontal scroll, Fixed px container widths, Disable zoom |
| 6 | Typography & Color | MEDIUM | typography, color |
Base 16px, Line-height 1.5, Semantic color tokens | Text < 12px body, Gray-on-gray, Raw hex in components |
| 7 | Animation | MEDIUM | ux, gsap |
Duration 150–300ms, Motion conveys meaning, Spatial continuity | Decorative-only animation, 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 |

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 10d ago First seen · 197 lines · 162 tokens per session scan A 658812bb3a1a
ui-ux-pro-max is a skill published in the GitHub repository nicohodt/claude-code-ui-ux-skill (3 stars, last pushed 9d ago), licensed MIT. It adds 162 tokens to every session and 3,361 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to ui-ux-pro-max, differing in 6 lines, and is treated as a copy.
