Evidence (BI as Code)
Build BI reports as code with Evidence. Writes SQL plus Markdown pages that render interactive charts and tables, parameterizes reports with query results, and ships polished, version-controlled data apps as static sites — no drag-and-drop BI.
This skill builds code-driven BI with Evidence: writing pages that mix SQL queries with Markdown to render interactive charts, tables, and value components, parameterizing reports and drill-downs with query results, templating pages over a dataset, and deploying the whole report as a fast static site that lives in version control alongside your code.
When to use
Use when building Evidence report pages, turning SQL results into interactive charts and tables, parameterizing a data app, or deploying an Evidence BI site.
