Germany (de): Use € symbol or mention "Germany", "Deutschland"
Poland (pl): Use zł symbol or mention "Poland", "Polska"
France (fr): Use € symbol or mention "France"

["gaming laptop", "Dell gaming", "HP Omen", "laptop"]

Bad queries (too specific):

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

3. When to Use Each Tool

shopping_search	User knows what they want, direct product searches
shopping_agent	Gift recommendations, need to clarify preferences
shopping_assistant_chat	Multi-turn conversation, slot filling needed
shopping_chat	Simple conversational queries

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

Always call the API via Bash tool - Use curl commands with proper JSON-RPC format
Parse JSON responses - Extract products array and format nicely for user
Include affiliate links - URLs in origin_url already contain tracking parameters
Market-specific currencies:
- gb: £ (GBP)
- de: € (EUR)
- pl: zł (PLN)
- fr: € (EUR)
Default to shopping_search - It's the most reliable tool for product searches
Multi-turn context - Remember previous queries to refine searches
Be conversational - This is a personal shopping assistant, not a robot
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! 🛍️
