What it does
Frontend Patterns is an agent skill from vibeeval/vibecosystem. React, Next.js, TypeScript frontend patterns - component design, state management, performance
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering State management and Web performance. It works with React, Next.js and TypeScript. The repository describes itself as: AI software team for Claude Code - 138 agents, 295 skills, 73 hooks. Self-learning, multi-agent swarm, autonomous skill evolution. The licence is MIT.
When your agent uses it

- Tasks that involve Web performance
Example prompts

Workflow steps

What it can do on your machine
Read from SKILL.md and the folder at commit 3b763b1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Frontend Patterns loads about 1k tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 232 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Frontend Patterns
Component Design
Composition over Inheritance
// DOGRU: Composition
function Card({ children, header }: { children: ReactNode; header: ReactNode }) {
return (
<div className="card">
<div className="card-header">{header}</div>
<div className="card-body">{children}</div>
</div>
);
}
// Kullanim
<Card header={<h2>Title</h2>}>
<p>Content here</p>
</Card>Container/Presenter Pattern
// Container: Data fetching + logic
function UserListContainer() {
const { data, isLoading } = useQuery(['users'], fetchUsers);
if (isLoading) return <Skeleton />;
return <UserList users={data} />;
}
// Presenter: Pure rendering
function UserList({ users }: { users: User[] }) {
return (
<ul>
{users.map(u => <UserItem key={u.id} user={u} />)}
</ul>
);
}State Management
| Cozum | Ne Zaman | Karmasiklik |
|---|---|---|
| useState | Local component state | Dusuk |
| useReducer | Complex local state | Orta |
| Context | Theme, auth, locale | Dusuk-Orta |
| Zustand | Global client state | Orta |
| React Query | Server state | Orta |
| URL params | Navigation state | Dusuk |
Performance
// React.memo: Expensive render onleme
const ExpensiveList = React.memo(({ items }: { items: Item[] }) => (
<ul>{items.map(i => <ListItem key={i.id} item={i} />)}</ul>
));
// useMemo: Expensive hesaplama cache
const filtered = useMemo(
() => items.filter(i => i.status === status),
[items, status]
);
// useCallback: Referans stabilitesi
const handleClick = useCallback((id: string) => {
setSelected(id);
}, []);Next.js Patterns
| Feature | Ne Zaman |
|---|---|
| Server Component | Data fetch, no interactivity |
| Client Component | onClick, useState, useEffect |
| Route Handler | API endpoint |
| Middleware | Auth, redirect, rewrite |
| Streaming | Buyuk data, progressive rendering |
shadcn/ui Best Practices
// Theme config: globals.css'te CSS variable kullan
// shadcn/ui dark mode: class strategy (Tailwind darkMode: 'class')
// Component override: cn() ile extend et, fork etme
import { Button } from '@/components/ui/button'
<Button variant="outline" className={cn('custom-class', className)} />
// Compose, override etme:
function SubmitButton({ children, ...props }: ButtonProps) {
return <Button type="submit" variant="default" {...props}>{children}</Button>
}
// A11y: shadcn radix tabanli, otomatik ARIA ama kontrol et
// Dark mode: CSS variable'lar otomatik switch ederPerformance Budget
