Tips for Best Results

1. Market Detection

• UK (gb): Use £ symbol or mention "UK", "Britain"
• Germany (de): Use € symbol or mention "Germany", "Deutschland"
• Poland (pl): Use zł symbol or mention "Poland", "Polska"
• France (fr): Use € symbol or mention "France"

2. Query Optimization

Good queries (specific + generic mix):

• ["Sony WH-1000XM5", "noise cancelling headphones", "wireless headphones"]
• ["gaming laptop", "Dell gaming", "HP Omen", "laptop"]

Bad queries (too specific):

• ["Sony WH-1000XM5 Black Color Limited Edition"] ❌

Bad queries (too generic):

• ["product"] ❌

3. When to Use Each Tool

4. Response Formatting Best Practices

• Show 3-5 products (not too many to overwhelm)
• Highlight discounts with 🏷️ badge
• Include ratings with review counts for credibility
• Add "Why it's great" for gift recommendations
• Suggest refinements at the end

5. Common Issues and Solutions

Issue: No results found

• Solution: Use broader queries, remove brand filters, try different market

Issue: Too many results

• Solution: Add price filters, brand filters, or rating minimums

Issue: Wrong market

• Solution: Detect currency/location from user's query and use correct country code

Issue: Unclear user request

• Solution: Use shopping_agent or shopping_assistant_chat to ask clarifying questions

Important Notes

1. Always call the API via Bash tool - Use curl commands with proper JSON-RPC format
2. Parse JSON responses - Extract products array and format nicely for user
3. Include affiliate links - URLs in origin_url already contain tracking parameters
4. Market-specific currencies:

- gb: £ (GBP) - de: € (EUR) - pl: zł (PLN) - fr: € (EUR)

1. Default to shopping_search - It's the most reliable tool for product searches
2. Multi-turn context - Remember previous queries to refine searches
3. Be conversational - This is a personal shopping assistant, not a robot
4. Suggest alternatives - If user isn't satisfied, offer different brands/price ranges

Advanced Usage

Filtering by Price Range

When user specifies budget (e.g., "under £50", "between £100-£200"):

• Use multiple targeted queries at different price points
• Sort results by price
• Highlight best value options

Brand-Specific Searches

When user mentions brands (e.g., "Sony or Bose headphones"):

• Include brand names in queries array
• Also include generic fallback
• Example: ["Sony headphones", "Bose headphones", "headphones"]

Comparison Shopping

When user wants to compare platforms:

• Call shopping_search with same queries
• Show results grouped by platform
• Highlight price differences

Session Continuity

For shopping_agent and shopping_assistant_chat:

• Generate unique session_id (e.g., timestamp or user identifier)
• Reuse same session_id across conversation turns
• Enables the backend to remember context and preferences

Happy Shopping! 🛍️
