What problem does it solve? Building Databricks AI/BI (Lakeview) dashboards by hand is error-prone: untested SQL queries, mismatched widget field names, wrong spec versions, and broken layouts cause "Invalid widget definition" errors. This Skill enforces a mandatory validate-then-deploy workflow so dashboards render correctly on the first deployment. ## Core Features & Use Cases - Mandatory SQL validation workflow: Requires testing every dataset query via execute_sql before calling create_or_update_dashboard, preventing broken widgets. - Complete widget specifications: Provides exact JSON patterns for counters, tables, bar/line/pie charts, text headers, and global or page-level filters, including correct spec versions and field-name matching rules. - Layout and readability rules: Enforces a 6-column grid with no gaps, recommended widget sizes, and cardinality limits so charts stay readable. - Use Case: Ask the agent to build a sales dashboard from a Unity Catalog table; it inspects the schema, tests each query, assembles the dashboard JSON with KPIs, charts, and filters, and deploys it to your workspace. ## Quick Start Create an AI/BI dashboard from the samples.nyctaxi.trips table showing total trips, average fare, and trips by pickup ZIP, then deploy it to my workspace.
