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 | $0.00086 | $0.00604 |
| Opus 5 | $0.00043 | $0.00302 |
| Sonnet 5 | $0.00017 | $0.00121 |
| Haiku 4.5 | $0.00009 | $0.00060 |
Grade A, and why
wicked-garden-engineering-frontend 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.
What it actually says
Frontend Skill
Specialized frontend engineering guidance for React, CSS, and browser-based applications.
When to Use
- Building React components
- CSS and styling questions
- Browser API usage
- Frontend performance optimization
- Accessibility (a11y) guidance
- User says "frontend", "React", "CSS", "component", "UI"
Key Focus Areas
React Patterns
- Component composition and single responsibility
- Hook usage (useState, useEffect, custom hooks)
- State management (context, props, lifting state)
- Performance (memo, useMemo, useCallback)
- Error boundaries
CSS & Styling
- Responsive design (flexbox, grid, media queries)
- Modern CSS (custom properties, container queries)
- Animations (GPU-accelerated)
- Theming and design systems
Browser APIs
- Fetch API and async operations
- Local/Session Storage
- Event handling
- Performance API
Accessibility
- Semantic HTML elements
- ARIA labels and roles
- Keyboard navigation
- Screen reader compatibility
- WCAG color contrast
Performance
- Code splitting and lazy loading
- Bundle optimization
- Image optimization
- Virtual scrolling
- Debouncing and throttling
Review Process
Use comprehensive checklists for:
- Component quality (responsibility, props, composition)
- React best practices (hooks, effects, state)
- Styling (responsiveness, consistency)
- Accessibility (semantic HTML, keyboard nav, ARIA)
See refs/checklists.md for detailed checklists, anti-patterns, and output templates.
Code Patterns
Common React and CSS patterns for:
- Component structure with TypeScript
- Custom hooks (debounce, etc.)
- Responsive design
- Accessibility patterns
- Performance optimization
See refs/patterns.md for code examples and best practices.
Notes
- Prioritize accessibility from the start
- Mobile-first responsive design
- Use semantic HTML before reaching for ARIA
- Test with keyboard navigation and screen readers
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

wicked-garden-engineering-frontend is a skill published in the GitHub repository mikeparcewski/wicked-garden (9 stars, last pushed yesterday), licensed MIT. It adds 86 tokens to every session and 604 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 2026-08-31.
