- `["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

| Tool | Use When |
|------|----------|
| **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

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
