react-vite-web

Coding rules for React applications built with Vite, a tool that develops and bundles web projects. They cover navigation, component folders, application state, forms, and API requests.

In plain words
What is it for?
Use them when building React pages, routes, reusable components, forms, data fetching, and client-side state in a Vite project.
Why use it?
They give a project a consistent structure and specify which library handles each kind of state, reducing ad hoc decisions across the codebase.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

react-vite-web scanned grade A with 1 finding 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 yesterday.

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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What it actually says

Web Rules (React + Vite)

Template for React projects using Vite.

Routing

  • React Router v6 for navigation
  • Lazy load route components with React.lazy()
  • Route guards in routes/guards/

Component Structure

State Management

Type Solution
Server State TanStack Query
Client State Zustand
Form State React Hook Form
URL State React Router

API Integration

// services/api.ts
export const apiClient = {
  get: <T>(url: string) => fetch(url).then(r => r.json() as T),
  post: <T>(url: string, data: unknown) => 
    fetch(url, { method: 'POST', body: JSON.stringify(data) }).then(r => r.json() as T),
};

// hooks/useUsers.ts
export const useUsers = () => useQuery({ queryKey: ['users'], queryFn: userService.list });

Component Patterns

// ✅ Good: Function component with typed props
interface ButtonProps {
  variant: 'primary' | 'secondary';
  onClick: () => void;
  children: React.ReactNode;
}

export function Button({ variant, onClick, children }: ButtonProps) {
  return <button className={styles[variant]} onClick={onClick}>{children}</button>;
}

Styling

  • CSS Modules or Tailwind CSS
  • Design tokens in styles/tokens.css
  • No inline styles except dynamic values

Changes

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.

react-vite-web is a cursor rule published in the GitHub repository WellApp-ai/Well (341 stars, last pushed 25d ago), licensed MIT. It adds 427 tokens to every session, about $0.0021 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
