Priority 1 (Critical): - Fix NULL handling in get_entity_timeline sort using datetime.min fallback - Add UUID validation to both get_entity_connections and get_entity_timeline - Add comprehensive automated integration tests (test_graph_exploration_int.py) Priority 2 (Important): - Improve exception handling with specific Neo4jError, ValueError, AttributeError - Add performance limitation documentation to tool docstrings - Generalize coaching references to technical/research examples Technical Details: - Import datetime and UUID for validation/sorting - Import Neo4jError for specific exception handling - Validate entity_uuid format before database calls - Handle None values in chronological sort with datetime.min - Add exc_info=True to error logging for better debugging - Sanitize error messages to avoid exposing internal details Test Coverage: - Tool availability verification - Invalid UUID validation - Nonexistent entity handling - Real data flow (add → search → explore) - Max limits parameter testing - Chronological ordering verification Performance Notes Added: - Document fetching behavior (database → application filtering) - Warn about high-degree nodes (1000+ connections/episodes) - Recommend smaller limits for large result sets All changes maintain backward compatibility and follow existing code patterns.
