Phase 2 Tools (8)

All Phase 2 intelligence tools are registered and accessible:

1. ✅ get_product_details_enhanced - Product attributes with user context
2. ✅ track_spending_patterns - Spending analytics by category/brand/store
3. ✅ optimize_offer_activation - Offer stacking optimization
4. ✅ get_user_location_context - Primary stores and venue distribution
5. ✅ discover_new_products - New product recommendations
6. ✅ get_household_context - Household members and shared patterns
7. ✅ predict_category_expansion - Category growth predictions
8. ✅ get_community_insights - Similar users and community trends

Points Tools (2)

Points tools are now properly registered with nil-safe handlers:

1. ✅ get_points_balance - Returns error message when API key not configured
2. ✅ get_redemption_options - Returns error message when API key not configured

Fix Applied:

• Removed conditional registration (if pointsClient != nil)
• Always register tools but return helpful error when client is nil
• Error message: “Points service is not configured. Please configure POINTS_API_KEY to use this feature.”

Issue Resolved

Problem

Failed to register tools with server: tool get_points_balance is enabled but not registered

Root Cause

• Points tools were only registered when pointsClient != nil
• In local env without POINTS_API_KEY, pointsClient was nil
• Tools were listed in tools-config.yml but not registered in registry

Solution

1. Modified pkg/tools/registry.go to always register points tools
2. Added nil checks in pkg/tools/points_balance.go handlers
3. Return user-friendly error when points service not configured

Files Modified

• pkg/tools/registry.go:77-80 - Removed conditional registration
• pkg/tools/points_balance.go:35-37 - Added nil check for get_points_balance
• pkg/tools/points_balance.go:88-90 - Added nil check for get_redemption_options
