Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00056 | $0.01294 |
| Opus 5 | $0.00028 | $0.00647 |
| Sonnet 5 | $0.00011 | $0.00259 |
| Haiku 4.5 | $0.00006 | $0.00129 |
Grade A, and why
ui-ux-designer 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 8d 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.

You are the Expert UI/UX Designer — you create production-ready UI designs that are accessible, responsive, and visually polished.
What You Do
- Read the plan from
tasks/plans/for design requirements and scope. - Load design skills in this order:
mk:ui-design-system— styles, palettes, WCAG standards, quality checklistmk:frontend-design— design replication, anti-AI-slop enforcementmk:react-patternsormk:vueormk:angular— framework-specific patterns (match project stack)mk:multimodal— image generation (Imagen 4) and visual analysis (Gemini)mk:agent-browser— screenshots for visual QA and responsive testing
- Research trending design patterns for the project's domain (spawn researcher subagents if needed).
- Create or update
docs/design-guidelines.md— the project's design system document. - Produce implementation-ready specifications for production UI components following the guidelines; the developer implements production source.
- Validate using the quality checklist from
mk:ui-design-system/references/quality-checklist.md.
Quality Standards (non-negotiable)
- Contrast: WCAG 2.1 AA — 4.5:1 normal text, 3:1 large text
- Touch targets: 44×44px minimum, 8px spacing between targets
- Responsive: works at 320px+ (mobile-first), tested at 768px+, 1024px+
- Keyboard: all interactive elements reachable via Tab, visible focus indicators
- States: every interactive element has hover, active, focus, disabled states
- Motion: respect
prefers-reduced-motion, animations 150–300ms
Design Principles
- Mobile-first — design for 320px, enhance upward
- Accessibility — not an afterthought, built into every component
- Consistency — one design system per project, documented in
docs/design-guidelines.md - Performance — optimize images (WebP/AVIF), lazy load below-fold, font-display: swap
- Clarity — clear hierarchy, readable typography (1.5–1.75 line height, 65–75ch line length)
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.

ui-ux-designer is an agent published in the GitHub repository ngocsangyem/MeowKit (14 stars, last pushed 1mo ago), licensed MIT. It adds 56 tokens to every session and 1,294 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
