wealvest-ai: Skill for Claude Code

When to Use

Use this skill when designing, building, or modifying interactive user interface widgets that display custom React content inside AI clients or NitroStudio.

1. Backend Definition (@Widget)

To display a React-based widget for a tool's output, decorate the tool method with @Widget.

Options:

• String Route: A simple string representing the route identifier in the frontend React app (e.g. 'product-card').
• Object Route: Object including:
  • route (required): The route path.
  • domain (optional): Allowed sandbox domain.
  • csp (optional): Content Security Policy guidelines.

Example:

import { Tool, Widget, z } from '@nitrostack/core';

export class CatalogTools {
  @Tool({
    name: 'fetch_product',
    description: 'Get product information by barcode.',
    inputSchema: z.object({ barcode: z.string() }),
  })
  @Widget('product-details') // Maps to the "product-details" frontend component
  async fetchProduct(input: { barcode: string }) {
    return {
      name: 'Super Nitro Energy Drink',
      price: 2.99,
      sku: input.barcode,
    };
  }
}

2. Frontend React Widget (@nitrostack/widgets)

In your React widget frontend application (typically a Next.js client component), use the useWidgetSDK hook to receive input data from the client host.

React Component Example:

'use client';

import React from 'react';
import { useWidgetSDK } from '@nitrostack/widgets';

interface ProductData {
  name: string;
  price: number;
  sku: string;
}

export default function ProductDetailsWidget() {
  const { isReady, getToolOutput, theme } = useWidgetSDK();
  const data = getToolOutput<ProductData>();

  if (!isReady) {
    return <div className="loading">Connecting to host...</div>;
  }

  if (!data) {
    return <div className="error">No product data received.</div>;
  }

  return (
    <div className={`product-card ${theme === 'dark' ? 'dark' : 'light'}`}>
      <h3>{data.name}</h3>
      <p className="price">${data.price.toFixed(2)}</p>
      <span className="sku">SKU: {data.sku}</span>
    </div>
  );
}
