基本スクレイピング

「[URL]から商品情報をスクレイピングして」
「[サイト]の全記事タイトルを抽出」

詳細指定

「URL: [target_url]
 抽出項目: [name, price, image, description]
 ページ数: [max_pages]
 出力形式: [CSV/JSON/Excel]」

技術スタック(ローカル版)

前提条件

npm install puppeteer cheerio

ブラウザベース(JavaScript必要なサイト)

const puppeteer = require('puppeteer');

async function scrapeWithBrowser(url, extractScript) {
  const client = await createClient({ headless: true });

  await client.executeSequence([
    { type: 'navigate', url: url },
    { type: 'wait', ms: 3000 }
  ]);

  // JavaScript実行でデータ抽出
  const data = await client.page.evaluate(() => {
    return [...document.querySelectorAll('.product')].map(el => ({
      name: el.querySelector('.name')?.textContent,
      price: el.querySelector('.price')?.textContent,
      image: el.querySelector('img')?.src
    }));
  });

  await client.close();
  return data;
}

HTTPベース(静的サイト)

const cheerio = require('cheerio');

async function scrapeStatic(url) {
  const response = await fetch(url);
  const html = await response.text();
  const $ = cheerio.load(html);

  return $('.product').map((i, el) => ({
    name: $(el).find('.name').text(),
    price: $(el).find('.price').text()
  })).get();
}

アンチボット対策

// ランダム遅延
await new Promise(r => setTimeout(r, 2000 + Math.random() * 3000));

// User-Agent設定
const client = await createClient({
  userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36'
});

nano-banana-pro

garg-aayush

Generate and edit images using Google's Nano Banana Pro (Gemini 3 Pro Image) API. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y"). Supports both text-to-image generation and image-to-image editing with configurable resolution (1K default, 2K, or 4K for high resolution). DO NOT read the image file first - use this skill directly with the --input-image parameter.
