## Quick Reference

### Semantic HTML Mapping
```
clickable action     → <button>          NOT <div onClick>
navigation link      → <a href>          NOT <span onClick>
navigation section   → <nav>             NOT <div class="nav">
main content         → <main>            NOT <div class="content">
modal/dialog         → <dialog>          NOT <div class="modal">
list of items        → <ul>/<ol>/<li>    NOT <div> repeated
section heading      → <h1>-<h6>         NOT <div class="title">
form field           → <input> + <label> NOT unlabeled input
```

### Focus Management Patterns
```typescript
// Modal: trap focus, restore on close
const previousFocus = useRef<HTMLElement>(null);
const openModal = () => {
  previousFocus.current = document.activeElement as HTMLElement;
  // focus first focusable in modal
};
const closeModal = () => {
  previousFocus.current?.focus();
};

// Route change: focus main heading
useEffect(() => {
  document.querySelector('h1')?.focus();
}, [pathname]);
```

### Required ARIA for Custom Components
- Tabs: `role="tablist"`, `role="tab"`, `aria-selected`, `aria-controls`
- Accordion: `aria-expanded`, `aria-controls`, button trigger
- Dropdown: `aria-haspopup`, `aria-expanded`, `aria-activedescendant`
- Toast: `role="status"`, `aria-live="polite"`
- Alert: `role="alert"`, `aria-live="assertive"`
- Loading: `aria-busy="true"`, `role="status"` with text

### Minimum Touch Target: 44×44px

generating-lwc-components

Included

Lightning Web Components with PICKLES methodology and 165-point scoring. Use this skill when the user creates or edits LWC components, builds wire service patterns, or writes Jest tests for LWC. TRIGGER when: user creates/edits LWC components, touches lwc/**/*.js, .html, .css, .js-meta.xml files, or asks about wire service, SLDS, or Jest LWC tests. DO NOT TRIGGER when: Apex classes (use generating-apex), Aura components, or Visualforce.

tanstack-query

Included

Manage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.

document-processor-api

Included

Process documents with Nutrient DWS. Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.
