Issues Resolved

Points Tools Registration

Problem: tool get_points_balance is enabled but not registered

Root Cause: Points tools were only registered when pointsClient != nil. In local environment without POINTS_API_KEY, pointsClient was nil, causing registration mismatch.

Solution:

1. Modified pkg/tools/registry.go - Always register points tools
2. Added nil checks in handlers (pkg/tools/points_balance.go)
3. Return helpful error message when service not configured

Result: All 31 tools now register correctly ✅

Database Schema Documentation

Created comprehensive schema documentation in COMPLETE_SCHEMA.md including:

• All 5 node types (User, Product, Retailer, Offer, Household)
• All 7 relationship types with detailed properties
• Calculation formulas (Jaccard similarity, price trends, predictions)
• Critical date/datetime type handling warnings
• Performance recommendations and suggested indexes

Verification Scripts
