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

| 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
