How It Works / 工作原理

Safe Data Collection Method

# Step 1: Search each platform via search engine
web_search(
    query="商品名称 site:jd.com OR site:tmall.com OR site:pdd.com",
    count=10,
    safeSearch="moderate"
)

# Step 2: Extract visible data from search snippets
# Only reads what's already indexed and publicly shown

# Step 3: Generate comparison report
# Combines data with context analysis

Key Safety Features:

  • ✅ No direct HTTP requests to target sites
  • ✅ No JavaScript execution or DOM parsing
  • ✅ No cookies or session manipulation
  • ✅ Rate-limited to prevent overloading search engines
  • ✅ Only uses public search results

Limitations / 局限性

Understand these constraints when using this skill:

What Search Results CAN Provide

  • ✅ List prices displayed in search snippets
  • ✅ Product titles and basic specifications
  • ✅ Sales volume indicators (if indexed)
  • ✅ Basic platform reputation signals

What Search Results CANNOT Provide

  • ❌ Member-only prices (requires login)
  • ❌ Real-time coupon calculations
  • ❌ Shipping costs to your specific location
  • ❌ Current stock availability
  • ❌ Live promotional discounts
  • ❌ Bundle deals requiring page interaction

Workarounds

For most accurate pricing:

  1. Manual Verification (Recommended)

    1. OpenClaw provides links to each platform
2. You manually open these pages
3. Tell me the actual prices you see
4. I'll generate final comparison

  2. Accept Approximate Data

    • Use search-based estimates for initial research
    • Verify final decision on-platform
    • Factor in potential ±10-20% price variance

Usage Best Practices / 最佳实践

DO ✅

  • Use for personal shopping decisions
  • Compare a few items occasionally
  • Verify important purchases on-platform
  • Respect rate limits (ask questions spaced out)
  • Accept data limitations gracefully

DON'T ❌

  • Use for commercial price monitoring
  • Request hundreds of comparisons at once
  • Try to get around login requirements
  • Distribute collected data to others
  • Treat search snippets as authoritative prices

Examples / 使用示例

Basic Comparison

User: 帮我比价华为 MateBook 14 2024 款
Agent: (Uses web_search → generates markdown report)

With Budget Constraint

User: 找 MacBook Air M2，不要超过 7000 元，包邮
Agent: (Filters by price constraint → shows matching options)

Platform-Specific

User: 只查京东自营和天猫旗舰店的价格
Agent: (Limits search to specified platforms only)
