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.
npx agentmods add rules/wellapp-ai/well/react-vite-webgit clone --depth 1 https://github.com/WellApp-ai/WellWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00427 | $0.00427 |
| Opus 5 | $0.00214 | $0.00214 |
| Sonnet 5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00043 | $0.00043 |
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.

Routing

State Management

| 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

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.
