Use this skill when an operator wants to analyze SourceMedium-hosted BigQuery data, verify BigQuery access, discover available SourceMedium tables or semantic metrics, generate safe SELECT-only SQL, produce auditable SQL receipts, or join their own warehouse tables to SourceMedium data. Do not use for DDL, DML, infrastructure provisioning, dbt authoring, or cross-tenant joins.
Use this skill when an operator wants to build a correct, accurate, and useful dashboard from SourceMedium BigQuery data or from their own warehouse tables joined to SourceMedium data. Default to a standalone HTML dashboard with auditable SQL receipts and portable chart specs. Also use for dashboard SQL planning, BI metric validation, chart selection, Metabase/Looker/Tableau-ready query handoff, or dashboard QA. Do not use for mutating warehouse data.
