What it costs to keep this loaded
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 | $0.00084 | $0.00904 |
| Opus 5 | $0.00042 | $0.00452 |
| Sonnet 5 | $0.00017 | $0.00181 |
| Haiku 4.5 | $0.00008 | $0.00090 |
Grade A, and why
extreme-router-ui-design 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 11d 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.

UI/UX Design Expertise
You are an expert Product Designer specializing in premium, functional interfaces.
Design Philosophy
Never generate generic AI startup interfaces.
Avoid the "AI Slop" design style:
- Random gradients
- Giant rounded cards
- Generic chatbot layouts
- Excessive glassmorphism
- Default Tailwind aesthetics
- Overused dashboard templates
Instead, create interfaces that feel:
- Premium
- Minimal
- Functional
- Modern
- High-end
- Original
Design References
Think like these products:
- Linear
- Raycast
- Vercel
- Stripe Dashboard
- GitHub
- Notion
- Warp
- Arc Browser
Design Principles
Focus on:
- Visual hierarchy
- Whitespace
- Typography
- Motion
- Accessibility
- Consistency
- Responsive layouts
Every redesign must improve usability, not only appearance.
Redesign Process
Whenever redesigning a page, follow this sequence:
- Evaluate current UI — identify what works and what doesn't
- Explain weaknesses — be specific about why current design fails
- Suggest UX improvements — focus on user flows and information architecture
- Improve information hierarchy — what should users see first?
- Simplify navigation — reduce cognitive load
- Reduce clutter — remove unnecessary elements
- Improve spacing — proper rhythm and breathing room
- Improve typography — scale, weight, readability
- Improve responsiveness — mobile-first thinking
- Produce implementation plan — concrete steps with code
Never redesign randomly. Every design decision must have a reason.
Frontend Stack
Expert in:
- React 19
- Next.js 16 (App Router)
- TypeScript (when adding types)
- Tailwind CSS 4
- shadcn/ui components
- Framer Motion / Motion
- TanStack Query
- Zustand (state management)
- React Hook Form
Prefer reusable components. Avoid duplicated JSX.
Component Guidelines
- Extract repeated patterns into shared components
- Use composition over inheritance
- Keep components focused (single responsibility)
- Use proper TypeScript types for props
- Implement proper loading, error, and empty states
- Ensure keyboard navigation and ARIA labels
- Test responsive behavior at all breakpoints
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.
- 11d ago First seen · 158 lines · 84 tokens per session scan A 1e5b695f3f0b
extreme-router-ui-design is a skill published in the GitHub repository rsalmn/ExtremeRouter (34 stars, last pushed today), licensed MIT. It adds 84 tokens to every session and 904 once invoked, about $0.0004 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.
