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.

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 | $0.00091 | $0.01525 |
| Opus 5 | $0.00046 | $0.00763 |
| Sonnet 5 | $0.00018 | $0.00305 |
| Haiku 4.5 | $0.00009 | $0.00153 |
Grade A, and why
frontend-ui-ux-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 12d 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.

Frontend UI/UX Design
Overview
This skill enables creation of production-ready frontend UI/UX designs from research through implementation. Follow a structured design process that balances user needs, business goals, technical constraints, and accessibility requirements.
Design Workflow
1. Understand Requirements
Gather Context:
- Project goals and success metrics
- Target audience and user personas
- Technical constraints (frameworks, browsers, devices)
- Brand guidelines and design language
- Accessibility requirements (WCAG level)
Clarify Scope:
- Type of deliverable (wireframes, mockups, design system, component library)
- Fidelity level (low, medium, high)
- Responsive breakpoints needed
- Browser and device support
2. Research & Strategy
User Research:
- Analyze user needs, goals, and pain points
- Review existing analytics or user feedback
- Identify key user journeys and scenarios
- Define information architecture
For complete research process: See uiux-design-process.md for detailed research, personas, journey mapping, and information architecture guidelines.
3. Design & Prototype
Create Wireframes:
- Start with low-fidelity layouts
- Focus on content hierarchy and structure
- Define user flows for key tasks
- Iterate based on feedback
Apply Visual Design:
- Define color palette (primary, secondary, semantic colors)
- Establish typography scale and spacing system
- Design components with variants and states
- Ensure visual hierarchy and consistency
For design principles: See design-principles.md for visual hierarchy, consistency, simplicity, feedback, and error prevention guidelines.
For design systems: See design-systems.md when building comprehensive design systems with design tokens, governance, and documentation.
4. Ensure Accessibility
WCAG Compliance:
- Minimum contrast ratios (4.5:1 for text, 3:1 for large text/UI)
- Keyboard navigation support
- Screen reader compatibility (semantic HTML, ARIA labels)
- Focus indicators and skip links
- Alternative text for images

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.

frontend-ui-ux-design is a skill published in the GitHub repository DauQuangThanh/hanoi-rainbow (17 stars, last pushed 7mo ago), licensed MIT. It adds 91 tokens to every session and 1,525 once invoked, about $0.0005 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 2026-08-31.
