### 4. Response Formatting Best Practices

- **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

**Issue**: Unclear user request

## 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)
5. **Default to shopping_search** - It's the most reliable tool for product searches
6. **Multi-turn context** - Remember previous queries to refine searches
7. **Be conversational** - This is a personal shopping assistant, not a robot
8. **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
