AI-first code editor with Composer
Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionreact-specialistExecute the skills CLI command in your project's root directory to begin installation:
Fetches react-specialist from 404kidwiz/claude-supercode-skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate react-specialist. Access via /react-specialist in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Invoke this skill when:
Do NOT invoke when:
Start here: What type of state?
├─ Server state (API data)?
│ ├─ Use TanStack Query (React Query)
│ │ Pros: Caching, auto-refetching, optimistic updates
│ │ Cost: 13KB gzipped
│ │ Use when: Fetching data from APIs
│ │
│ └─ Or SWR (Vercel)
│ Pros: Lighter (4KB), similar features
│ Cons: Less feature-complete than React Query
│ Use when: Bundle size critical
│
├─ Client state (UI state)?
│ ├─ Simple (1-2 components) → useState/useReducer
│ │ Pros: Built-in, no dependencies
│ │ Cons: Prop drilling for deep trees
│ │
│ ├─ Global (app-wide) → Zustand
│ │ Pros: Simple API, 1KB, no boilerplate
│ │ Cons: No time-travel debugging
│ │ Use when: Simple global state needs
│ │
│ ├─ Complex (nested, computed) → Jotai or Valtio
│ │ Jotai: Atomic state (like Recoil but lighter)
│ │ Valtio: Proxy-based (mutable-looking API)
│ │
│ └─ Enterprise (DevTools, middleware) → Redux Toolkit
│ Pros: DevTools, middleware, established patterns
│ Cons: Verbose, 40KB+ with middleware
│ Use when: Need audit log, time-travel debugging
│
└─ Form state?
├─ Simple (<5 fields) → useState + validation
├─ Complex → React Hook Form
│ Pros: Performance (uncontrolled), 25KB
│ Cons: Learning curve
│
└─ With schema validation → React Hook Form + Zod
Full type safety + runtime validation
| Issue | Symptom | Solution | Expected Improvement |
|---|---|---|---|
| Slow initial load | FCP >2s, LCP >2.5s | Code splitting (React.lazy) | 40-60% faster |
| Re-render storm | Component renders 10+ times/sec | React.memo, useMemo | 80%+ reduction |
| Large bundle | JS bundle >500KB | Tree shaking, dynamic imports | 30-50% smaller |
| Slow list rendering | List >1000 items laggy | react-window/react-virtualized | 90%+ faster |
| Expensive computation | CPU spikes on interaction | useMemo, web workers | 50-70% faster |
| Prop drilling | 5+ levels of props | Context API or state library | Cleaner code |
| Use Case | Pattern | Complexity | Flexibility | Example |
|---|---|---|---|---|
| Simple UI | Props + children | Low | Low | <Button>Click</Button> |
| Configuration | Props object | Low | Medium | <Button config={{...}} /> |
| Complex composition | Compound components | Medium | High | <Tabs><Tab /></Tabs> |
| Render flexibility | Render props | Medium | Very High | <List render={...} /> |
| Headless UI | Custom hooks | High | Maximum | useSelect() |
| Polymorphic | as prop |
Medium | High | <Text as="h1" /> |

Common Pitfalls
✓ Do
✗ Don't
💡 Pro Tips
✓ Use when
Use when skill capabilities match your task, clear ROI on time saved, and you can validate outputs. Best for repetitive tasks, learning, and quality improvement.
✗ Avoid when
Avoid when task requires deep expertise you can't validate, involves sensitive decisions, or when learning process is more valuable than speed of completion.
