Next steps: Add custom context

You can add custom context to help the AI better understand your data structure and business logic. Consider adding context at the database or schema level if you notice the AI struggling to locate or understand specific data.

When to add context

• Complex analytics data: When the AI needs help understanding data structure and metrics
• Business-specific metrics: If calculated fields or KPIs need additional explanation
• Unclear naming conventions: When table or column names don’t clearly indicate their purpose

For detailed guidance, see our custom context documentation.
