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 | $0.00042 | $0.00545 |
| Opus 5 | $0.00021 | $0.00272 |
| Sonnet 5 | $0.00008 | $0.00109 |
| Haiku 4.5 | $0.00004 | $0.00055 |
Grade A, and why
frontend-audit 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.

Auto-Triggered Checklist
When this skill activates on a frontend file:
- Component Structure — Composition over prop drilling, proper state management
- Accessibility — ARIA labels, keyboard navigation, color contrast, semantic HTML
- Responsive Design — Mobile-first breakpoints, touch targets, viewport handling
- Performance — Lazy loading, code splitting, image optimization, bundle size
- Error States — Empty states, loading skeletons, error boundaries, offline handling
- Design System — Token consistency, spacing scale, typography hierarchy
- TypeScript — Strict typing, no
any, proper interfaces for props
Quality Dimensions (score 1-10)
| Dimension | What to Check |
|---|---|
| Visual Design | Color system, typography, spacing, hierarchy, dark mode |
| Component Architecture | Composition, reusability, state management |
| Performance | Bundle size, LCP, FID, CLS, lazy loading |
| Accessibility | WCAG 2.1 AA, keyboard nav, screen readers |
| Responsive | Mobile-first, breakpoints, touch targets |
| Animation | Transitions, micro-interactions, loading states |
| Error States | Empty, error, loading, offline, stale data |
| Code Quality | TypeScript strict, naming, DRY, file structure |
Red Flags — STOP If You See These
- Components with more than 5 levels of prop drilling
- Missing loading/error/empty states on data-fetching components
- Hardcoded pixel values instead of design tokens
- No keyboard navigation support on interactive elements
- Images without alt text or width/height attributes
- Client-side data fetching without SWR/React Query caching
- Inline styles instead of design system classes
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-audit is a skill published in the GitHub repository ShaheerKhawaja/ProductionOS (8 stars, last pushed 4mo ago), licensed MIT. It adds 42 tokens to every session and 545 once invoked, about $0.0002 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.
