Quick Start (For AI)
When to use this skill : When user asks to analyze, research, or extract insights from e commerce products (Amazon, Temu, Shopee).
What you should do :
1. Extract product identifiers (ASINs or URLs) from user input
2. Call the scraper script to get product data
3. Call the AI analysis with the analysis prompt template
4. Output results in BOTH formats: Google Sheets + Markdown
Input examples :
"Analyze B0C4YT8S6H"
"Analyze these products: B0C4YT8S6H, B08N5WRQ1Y, B0CLFH7CCV"
"Research this competitor: https://amazon.com/dp/B0C4YT8S6H"
Output requirements :
Google Sheets table with: ASIN, Title, Price, Rating, 4 analysis summaries
Markdown report with detailed 4 dimensional analysis
How AI Should Process Requests
Step 1: Extract Product Identifiers
From user input, extract all ASINs and/or URLs:
Example inputs :
Extract : ['B0C4YT8S6H', 'B08N5WRQ1Y', 'B0CLFH7CCV']
Mixed input handling :
Extract : ['B0C4YT8S6H', 'B08N5WRQ1Y'] (extract ASIN from URL)
Step 2: Batch Scrape Product Data
For each product identifier:
1. Detect platform (use scripts/detect platform.js if available)
2. Call appropriate scraper (Amazon: scripts/scrape amazon.js )
3. Use Olostep API with configured API key from .env
Batch processing pattern :
Step 3: Batch AI Analysis
For each successfully scraped product:
1. Read the analysis prompt from prompts/analysis prompt base.md
2. Replace product data placeholders in the prompt
3. Call Gemini API (model: gemini 3 flash preview)
4. Extract structured analysis results
Analysis framework (4 dimensions):
1. 文案构建逻辑与词频分析 (The Brain) Copywriting strategy & keywords
2. 视觉资产设计思路 (The Face) Visual design methodology
3. 评论定量与定性分析 (The Voice) Review sentiment analysis
4. 市场维态与盲区扫描 (The Pulse) Market positioning & blind spots
Step 4: Generate Dual Format Output
Format 1: Google Sheets (Structured Data)
Write to Google Sheets with columns:
ASIN 产品标题 价格 评分 文案分析摘要 视觉分析摘要 评论分析摘要 市场分析摘要
Sheet selection priority :
1. User explicitly specified Sheet ID/Name/URL
2. Default from .env ( GOOGLE SHEETS ID )
3. Ask user to provide Sheet ID
Format 2: Markdown Report (Detailed Analysis)
Generate file: 竞品分析 YYYY MM DD.md
Structure:
File Structure
Configuration Files
platforms.yaml
Contains platform specific configurations:
URL patterns for platform detection
ASIN extraction regex patterns
Scraper API endpoints
Data extraction patterns
Key sections :
.env.example
Template for required API keys:
Critical : Always check if .env file exists and contains required keys before processing.
Analysis Prompt Template
The AI analysis uses a proven 4 dimensional framework. The exact prompt is stored in:
prompts/analysis prompt base.md
Key sections :
1. Role : 10 year experienced Amazon Operations Director & Brand Strategist
2. Goal : Deep scan of product listing to extract strategic insights
3. Output Structure :
Part 1: 文案构建逻辑与词频分析
Part 2: 视觉资产设计思路
Part 3: 评论定量与定性分析
Part 4: 市场维态与盲区扫描
Important : Use the prompt EXACTLY as provided in the template without modifications.
API Services
Olostep API (Web Scraping)
Purpose : Scrape Amazon product pages with rendered JavaScript
Endpoint : https://api.olostep.com/v2/agent/web agent
Cost : 1000 free requests/month, then $0.002/request
Key param : comments to scrape: 100 (matching n8n config)
Google Gemini API (AI Analysis)
Purpose : Generate comprehensive product analysis
Model : gemini 3 flash preview (cost effective)
Cost : ~$0.001/product
Alternative : gemini 2 flash thinking (for complex analysis)
Google Sheets API (Data Storage)
Purpose : Export structured results
Authentication : OAuth2 service account
Cost : Free tier
Error Handling
Batch Processing with Error Isolation
Critical pattern from n8n workflow :
Common Errors & Solutions
Error Cause Solution
OLOSTEP API KEY not found Missing .env file Check .env exists and contains key
Invalid ASIN format Malformed ASIN Validate ASIN: 10 alphanumeric chars
Scraping timeout Slow page load Increase timeout or retry
Gemini rate limit Too many requests Add delay between batches
Platform Detection Logic
Implementation Notes
Current Version: Phase 1 MVP
Supported Platforms : Amazon (US only)
Input Method : Dialog based (ASINs or URLs)
Output Format : Google Sheets table + Markdown report
Roadmap
✅ Phase 1: Amazon MVP (current)
🔄 Phase 2: Add Temu & Shopee platforms
🔄 Phase 3: Cross platform comparison
🔄 Phase 4: Historical tracking & price alerts
Design Philosophy
This skill follows the error isolation pattern from the n8n workflow:
Single product failure NEVER stops the entire batch
Always report both successes and failures
Provide detailed error messages for debugging
Performance Benchmarks
Operation Time Cost
Single product scrape ~30 seconds $0.002 (Olostep)
Single product analysis ~45 seconds $0.001 (Gemini)
Total per product ~1 2 minutes ~$0.003
Batch of 10 products ~10 15 minutes (parallel) ~$0.03
References
n8n Workflow : Based on v81 workflow logic
Platform Config : See platforms.yaml for URL patterns and extraction rules
Analysis Prompt : See prompts/analysis prompt base.md for exact prompt template
Important Reminders for AI
1. ALWAYS extract ALL product identifiers from user input before processing
2. ALWAYS use batch processing with Promise.allSettled for error isolation
3. ALWAYS generate BOTH output formats : Google Sheets + Markdown
4. NEVER modify the analysis prompt use it exactly as provided
5. ALWAYS validate .env exists before starting processing
6. ALWAYS report processing summary : X succeeded, Y failed
7. If Google Sheets ID is missing , ask user to provide it
8. Use the exact prompt from prompts/analysis prompt base.md without any modifications
