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 | $0.00146 | $0.02611 |
| Opus 5.5 | $0.00058 | $0.01044 |
| Sonnet 5.5 | $0.00029 | $0.00522 |
| Haiku 4.5 | $0.00015 | $0.00261 |
Grade A, and why
frontend-design-review 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 1mo 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 Design Review
Overview
This skill provides expert guidance for conducting thorough frontend design reviews, covering UI/UX design quality, design system consistency, accessibility compliance, and responsive design patterns. The skill helps identify design issues early in the development lifecycle, ensuring designs meet quality standards, accessibility requirements, and business objectives before implementation.
Core Capabilities
1. UI/UX Design Quality Review
- Visual design assessment (typography, color, spacing, layout, visual hierarchy)
- User experience evaluation (flows, interactions, navigation, usability)
- Design consistency verification across screens and journeys
- Brand alignment and visual identity validation
- Cognitive load analysis
2. Design System Validation
- Component library review (design, variants, states, reusability)
- Design tokens validation (colors, typography, spacing)
- Pattern library assessment for consistency
- Documentation quality evaluation
- Design system governance assessment
3. Accessibility Compliance
- WCAG 2.1 AA compliance verification
- Color contrast validation (4.5:1 text, 3:1 UI components)
- Keyboard navigation and focus management
- Screen reader support validation
- Accessible interaction patterns review
4. Responsive Design Review
- Breakpoint strategy evaluation
- Mobile-first approach assessment
- Touch target sizing verification (44x44px minimum)
- Content adaptation across viewports
- Performance considerations
5. Component Architecture Assessment
- Component hierarchy and composition patterns
- Reusability and flexibility evaluation
- State management review (default, hover, active, disabled, error, loading)
- Component variants and customization patterns
- Component documentation quality
Workflow
Phase 1: Pre-Review Preparation
1. Gather Design Assets
- Collect Figma/Sketch files, design specifications, mockups
- Obtain design system documentation and component library
- Review brand guidelines and style guides
- Gather user research findings and personas

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-design-review is a skill published in the GitHub repository DauQuangThanh/hanoi-rainbow (17 stars, last pushed 9mo ago), licensed MIT. It adds 146 tokens to every session and 2,611 once invoked, about $0.0006 per session on Opus 5.5. 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.
