What problem does it solve? Building Databricks AI/BI (Lakeview) dashboards by hand often produces broken widgets, field name mismatches, and invalid widget definition errors because the dashboard JSON schema has strict versioning, encoding, and layout rules. This Skill enforces a mandatory validate-then-deploy workflow so every SQL query is tested before the dashboard is deployed. ## Core Features & Use Cases - Mandatory SQL validation workflow: Test every dataset query via execute_sql before deploying, preventing broken widgets. - Widget specifications: Correct version and encoding rules for counters (v2), tables (v2), bar/line/pie charts (v3), text headers, and filter widgets. - Layout and filter guidance: 6-column grid layout with no gaps, plus global vs page-level filters using PAGE_TYPE_GLOBAL_FILTERS and PAGE_TYPE_CANVAS. - Use Case: A data analyst needs a KPI dashboard over Unity Catalog sales data with region filters; the Skill walks through schema inspection, query testing, JSON construction, and deployment via create_or_update_dashboard. ## Quick Start Ask the agent to build an AI/BI dashboard on Databricks from a specified Unity Catalog table, including KPI counters, charts, and filters.
